The Rise of Multi-Functional Travel Lighting
The Modern Traveler’s Dilemma
Gone are the days when travel meant disconnecting completely. Today’s journeys blend work and leisure, often in the same 24-hour period. You might spend the morning reviewing contracts on your laptop in a hotel lobby, then unwind with a paperback in a poorly lit Airbnb bedroom that evening. Carrying separate task lights for each activity isn’t just impractical—it’s a violation of minimalist packing philosophy. The friction of fumbling with inadequate overhead airplane lights or straining your eyes in a hostel dorm after lights-out has created a genuine need for adaptable solutions that respect both your luggage weight limit and your retinal health.
How Dual-Purpose Lights Solve Common Problems
A well-engineered clip-on light addresses multiple pain points simultaneously. The same precision optics that cast an even glow across textbook pages can eliminate screen glare when positioned above a laptop. The sturdy clip that secures to a thick hardcover can just as easily grip a laptop bezel without damaging delicate screens. This convergence means one less charger to pack, one less item to remember at the security checkpoint, and one less gadget cluttering your workspace. More importantly, it provides consistent, personalized lighting that adapts to your environment rather than forcing you to adapt to inadequate illumination.
Core Features That Define Quality
Brightness Levels and Lumen Output
When evaluating any portable light, lumen output tells only part of the story. For dual-purpose use, you need a range—typically between 50 and 300 lumens—to accommodate different scenarios. Reading a printed page in pitch darkness requires surprisingly little light (around 80-100 lumens), while compensating for harsh overhead office lighting might demand the full 300. Look for models offering at least five distinct brightness levels rather than simple high-medium-low settings. This granularity lets you fine-tune illumination to prevent eye strain during extended use. The sweet spot for most travelers is a light that can dim low enough for intimate reading but crank up high enough to make video calls look professional.
Color Temperature Control
The ability to shift between warm and cool light isn’t just a luxury—it’s essential for both productivity and circadian rhythm management. Cool white light (5000K-6500K) boosts alertness and is ideal for laptop work, making your screen appear crisper and reducing perceived eye fatigue. Warm light (2700K-3500K), conversely, preserves melatonin production for pre-sleep reading. Premium models offer a continuous spectrum adjustment rather than preset steps, letting you dial in the exact temperature for your environment. Some even include a “neutral” 4000K setting that splits the difference for versatile use. For travelers crossing time zones, this feature becomes a powerful tool for managing jet lag and maintaining sleep hygiene.
Beam Angle and Light Distribution
A narrow spotlight might work for highlighting textbook margins but will create harsh hotspots on a laptop screen. Conversely, an overly wide floodlight wastes lumens and can disturb seatmates on planes. The ideal dual-purpose light employs a beam angle between 30° and 60°, with advanced optics that create an even, edge-to-edge illumination pattern. Look for descriptions like “asymmetric lighting” or “anti-glare diffusion”—these indicate engineering that directs light downward onto your workspace while minimizing stray photons that might annoy others or reflect off your screen. Some designs incorporate adjustable heads that rotate 180 degrees, allowing you to modify the beam direction without repositioning the entire clip.
Power Solutions for Travel
Battery Types and Longevity
Lithium polymer batteries dominate the category for good reason—they pack maximum capacity into minimal space. However, capacity ratings (measured in mAh) can be misleading. A 2000mAh battery might power a 100-lumen light for 8 hours but drain in 2.5 hours at maximum brightness. Real-world usage matters more than specifications. For travel, prioritize lights that offer at least 6 hours of runtime at medium brightness, which typically translates to 3-4 hours at high settings. Some advanced models feature replaceable batteries—a game-changer for multi-week trips where charging opportunities are scarce. Just ensure spare batteries are carried in compliance with airline regulations, typically requiring them to be in carry-on luggage only.
USB-C Charging Standards
The universal adoption of USB-C has revolutionized travel gear, but not all USB-C ports are equal. Seek lights that support USB-C PD (Power Delivery) for faster charging—ideally replenishing to 80% capacity in under 90 minutes. More importantly, verify that the light can charge while operating. This “pass-through” functionality means you can plug into a power bank during a long-haul flight and never experience darkness. Be wary of proprietary charging cables; they become single points of failure. The best travel lights charge via standard USB-C to USB-C cables, eliminating the need to carry yet another cord. Some even function as emergency power banks themselves, though this feature often sacrifices lighting performance.
Power Bank Compatibility
Your clip-on light should play nice with your existing power ecosystem. Models drawing less than 5V/1A can run indefinitely from even modest power banks, effectively giving you unlimited runtime. This is particularly valuable for camping or remote work scenarios. Check the light’s minimum operating voltage—some sophisticated models with touch controls require a stable 5V supply and may flicker or shut off when connected to low-quality power banks with inconsistent output. The most travel-savvy designs include a power indicator that shows remaining battery percentage rather than ambiguous LED dots, letting you plan charging sessions proactively.
Mounting Mechanisms and Versatility
Clip Strength and Grip Range
The clip mechanism determines whether your light becomes an indispensable tool or a constant source of frustration. A quality clip opens at least 1.5 inches to accommodate thick textbooks, clipboards, and laptop lids. The internal padding deserves scrutiny—silicone or rubber grips prevent slippage without marring surfaces, while foam padding degrades quickly and leaves residue. Spring tension should be firm enough to hold securely on a vertical laptop screen but not so aggressive that it damages delicate e-reader bezels. Test the clip’s “mouth” design: flat-edged clips suit laptop screens, while curved or contoured jaws grip book spines more naturally. Some premium models feature interchangeable clip inserts for different surfaces.
Laptop Screen Compatibility
Attaching a light to a laptop requires finesse. The ideal clip distributes pressure across a wide area to avoid creating pressure points on LCD panels. Look for models with a minimum contact surface area of 2 square inches and padding that’s at least 2mm thick. The clip’s profile should be low enough to avoid interfering with laptop cases or sleeves. For MacBook users, the tapered screen design demands clips with adjustable jaw angles—rigid clips will apply uneven pressure and may slip. Some lights include a “laptop mode” that automatically reduces brightness to prevent screen glare, a thoughtful touch that shows manufacturer attention to real-world use.
Book Spine and Edge Clamping
Traditional book lights clamp to the top of a page, but this creates shadows and limits page-turning. Modern designs clip to the back cover or spine, casting light across the entire open spread. This approach requires a clip that can grip thin paperback spines without damaging binding glue while also handling leather-bound hardcovers. The best designs feature a rotating head that lets you position the light source above the gutter (center binding) for perfectly even illumination. For travelers who read in multiple languages, consider how the clip handles right-to-left texts—some asymmetrical designs only work optimally with left-page clamps.
Portability Factors
Weight and Size Considerations
Every ounce matters when you’re living out of a backpack. The most travel-friendly lights weigh under 3 ounces (85 grams) and collapse to pocket dimensions—roughly 6 inches long when folded. However, ultralight designs often compromise on battery capacity or clip robustness. The sweet spot for most users is 4-6 ounces, which provides sufficient battery life and durable construction without noticeable pack weight. Pay attention to the light’s center of gravity when clipped; a top-heavy design will constantly tilt forward on a laptop screen. The most packable models fold flat, with the LED head tucking into the clip body, creating a slim profile that slides into laptop sleeves or book pockets.
Foldable and Collapsible Designs
A light that folds in multiple directions offers unmatched positioning flexibility. Look for at least two hinge points: one at the clip-neck junction and another at the neck-head junction. This allows you to position the light parallel to a book page or perpendicular to a laptop screen. Some innovative designs incorporate a telescoping neck, extending reach from 4 to 8 inches—useful for illuminating large textbooks or creating distance from a glossy laptop screen. The folding mechanism should feel precise, not loose; quality models use metal pins and friction washers rather than plastic tabs that wear out. Test the range of motion: can the light point straight up for use as an ambient tent lamp? Can it angle downward 90 degrees for reading in bed?
Travel Cases and Protection
While many travelers skip cases to save space, a simple protective pouch prevents the light from turning on accidentally in your bag and draining the battery. The best cases are integrated—built into the light’s design as a foldable cover that protects the LED lens. If a separate pouch is included, ensure it’s slim enough to be worthwhile. Some premium models feature a travel lock function: holding the power button for 3 seconds disables all controls until repeated. This electronic solution eliminates the need for a case entirely. Consider whether the charging port has a dust cover; exposed USB-C ports collect lint and debris from backpack interiors, eventually causing connection issues.
Light Quality and Eye Protection
Flicker-Free Technology
Invisible to the naked eye, PWM (Pulse Width Modulation) flicker can trigger headaches and eye fatigue during extended use. Quality lights use constant current drivers that eliminate flicker across all brightness levels. How can you verify this without specialized equipment? Wave the light quickly in front of your phone’s camera—if you see strobing bands, the light uses low-frequency PWM. Premium models advertise “flicker-free” or “eye-care” technology and typically operate at frequencies above 20kHz, well beyond human perception. For laptop use, this is non-negotiable; screen flicker compounded by light flicker multiplies eye strain exponentially.
Blue Light Filtering
While blue light gets blamed for sleep disruption, the reality is more nuanced. Quality travel lights filter out the specific 415-455nm wavelength range that’s most disruptive to circadian rhythms while preserving the 460-500nm range that maintains alertness and color accuracy. Look for lights with a “reading mode” that automatically shifts to warmer temperatures and reduces blue light emission by 70% or more. Some models include a physical filter that slides over the LED, transforming the light into a pure amber source for pre-sleep reading. Be skeptical of vague “blue light reduction” claims—reputable manufacturers specify the exact percentage reduction and wavelength range affected.
Glare Reduction Features
Glare occurs when bright light reflects off glossy surfaces—a common issue with laptop screens and magazine pages. Advanced lights use textured diffusers that scatter light rays, creating a soft glow rather than harsh points. The LED’s position relative to the diffuser matters: recessed LEDs (set back 5mm or more) provide better diffusion than flush-mounted chips. For laptop use, the ability to angle the light source away from the screen is crucial. Some models include a polarizing filter that aligns light waves to minimize reflections—a feature borrowed from photography lighting that works remarkably well for digital nomads.
Durability for Travel
Material Selection
Travel gear endures abuse: crushed in overhead bins, jostled in backpacks, dropped on hostel floors. Polycarbonate bodies offer the best strength-to-weight ratio, resisting cracks and impacts better than ABS plastic. Metal clips, preferably aluminum alloy, maintain spring tension far longer than plastic alternatives. The finish matters too—matte textures hide scratches and provide better grip than glossy surfaces. For the lens, acrylic is lighter but scratches easily; tempered glass maintains clarity but adds weight. Some manufacturers use sapphire-coated polymer lenses that combine the best of both: scratch resistance at minimal weight. Check the IP rating—IPX4 indicates splash resistance, protecting against rain or spilled coffee, while IPX7 means brief submersion survival.
Hinge and Joint Longevity
The folding mechanism is typically the first failure point. Quality lights use metal pins through metal housings, often with brass bushings for smooth rotation. Plastic-on-plastic hinges develop play within months of travel use. Test the hinge tension: it should hold position without drifting but move smoothly when adjusted. Some premium models include user-tightenable screws, allowing you to restore stiffness as the mechanism wears. The cable routing through hinged necks deserves attention—look for strain relief boots where wires exit the housing. Repeated bending can fracture internal connections, rendering the light useless. The best designs route cables through the center of rotation, minimizing flex.
Warranty and Support
A two-year warranty indicates manufacturer confidence in travel-grade durability. Read the fine print: does coverage include “normal wear and tear” or only manufacturing defects? Some brands offer “no-questions-asked” replacement policies specifically for travelers, understanding that gear fails in unpredictable ways. Check the repairability—are replacement batteries available for purchase? Can you buy a new clip mechanism if yours breaks? Companies that sell spare parts demonstrate a commitment to longevity over planned obsolescence. For international travelers, verify whether warranty service is available globally or only in the country of purchase.
Smart Features and Modern Tech
Touch Controls vs Physical Buttons
Touch-sensitive panels look sleek but frustrate when you can’t locate them in the dark. Physical buttons provide tactile feedback but can wear out. The hybrid approach works best: a physical power button with touch sliders for brightness and temperature adjustment. Some models incorporate haptic feedback—subtle vibrations confirm your input without requiring visual confirmation. For travel, glove compatibility matters if you’re heading to cold climates; capacitive touch screens won’t work with gloves, while physical buttons do. Consider accidental activation: touch controls are more prone to being bumped in a bag, though travel lock features mitigate this.
Memory Functions
A light that remembers your last-used settings saves frustration. This seems simple but requires non-volatile memory that preserves settings even when the battery dies completely. Premium models store separate profiles for different usage modes—one brightness for reading, another for video calls. Some even detect orientation: clip it to a book and it defaults to warm 3000K; position it on a laptop and it switches to cool 5500K. This contextual awareness, powered by accelerometers, represents the cutting edge of travel lighting design. For multi-user scenarios, look for lights with profile switching, allowing you and a travel partner to maintain separate preferences.
Auto-Dimming and Ambient Sensors
Built-in light sensors that adjust brightness based on ambient conditions sound gimmicky but prove invaluable in practice. They prevent the jarring transition when cabin lights suddenly dim or when moving from a sunny café to a shadowy corner. The sensor should face away from the LED to avoid feedback loops—some poorly designed models brighten indefinitely when their own reflection triggers the sensor. Advanced implementations include a “delay” setting, preventing the light from flickering with every passing cloud. For laptop use, ensure the sensor can be disabled; screen brightness changes can confuse the auto-dimming algorithm, creating an annoying brightness tug-of-war.
Price vs. Value Analysis
Budget Tier Expectations
Sub-$20 lights cut corners, but intelligently. Expect plastic clips, micro-USB charging, and fixed color temperatures. Runtime claims are often optimistic—halve the advertised hours for realistic expectations. These models suit occasional travelers or those wanting to test the concept without commitment. The primary compromise is longevity; budget lights typically last 12-18 months of regular travel use before hinges loosen or batteries degrade. However, some hidden gems in this category sacrifice fancy features for solid fundamentals: a simple, bright LED with a strong clip and decent battery. If you prioritize function over finesse, budget tier can deliver surprising value.
Mid-Range Sweet Spot
The $30-$60 range represents the optimal intersection of features, durability, and price. Here you’ll find USB-C charging, adjustable color temperatures, metal-reinforced clips, and true flicker-free operation. Battery capacities become honest, often exceeding 10 hours at moderate brightness. This tier introduces thoughtful details like cable management clips, protective carrying pouches, and international warranty support. The mid-range is where manufacturers compete hardest for discerning customers, resulting in exceptional value. Most serious travelers will find their perfect match in this category without paying for unnecessary premium flourishes.
Premium Features Worth Paying For
Above $60, you’re paying for refinement rather than revolution. Premium lights offer aerospace-grade materials, custom LED arrays with exceptional color rendering (CRI >95), and sophisticated control apps. The Lupine Systems model includes a “theater mode” that dims to imperceptible levels for discreet note-taking during performances. Another high-end feature is wireless charging—simply place the light on a Qi pad alongside your phone. For professionals who spend 8+ hours daily under artificial light, these enhancements justify the cost. The law of diminishing returns applies heavily here; a $100 light isn’t twice as good as a $50 model, but it might be 30% better in ways that matter to power users.
Real-World Use Cases
Red-Eye Flights and Train Journeys
Airplane seat lighting is notoriously inadequate, and your seatmate doesn’t appreciate your overhead light during their sleep. A clip-on light with a narrow beam angle (30°) focuses illumination precisely on your tray table or open book, creating a personal bubble of light. The key is positioning: clip to the seatback pocket edge or the tray table hinge, angling the light to avoid casting shadows on your work. For overnight trains, where vibrations are constant, a clip with rubberized grips prevents the light from slowly sliding down surfaces. The ability to dim to extremely low levels (under 20 lumens) allows you to check documents without disturbing others in darkened cabins.
Hostel and Shared Space Etiquette
In dormitory settings, your light directly impacts others’ sleep quality. A model with a dedicated “roommate mode” uses a physical light baffle to direct illumination downward in a 180° pattern, eliminating upward light spill. Color temperature becomes crucial here; warm amber light is less disruptive to sleeping neighbors than cool white. Some travelers clip lights to bunk bed frames, requiring a 360° rotating head to position the beam correctly. The quiet operation of touch controls prevents the click-clack of buttons from echoing in silent rooms. Battery life takes priority—you can’t charge while sleeping in a shared room without monopolizing scarce outlets.
Camping and Outdoor Versatility
Beyond reading and laptops, these lights become tent lanterns, cooking assistants, and map readers. A clip that opens wide enough to grip tent poles or tree branches expands functionality dramatically. Weather resistance (IPX4 minimum) protects against dew and light rain. The ability to stand independently—either via a flat base or by clipping to itself to form a loop—creates a makeshift lantern. Some models include a red LED mode that preserves night vision for stargazing or wildlife observation. The battery’s performance in cold weather matters; lithium polymer cells lose capacity below freezing, so lights with insulation or low-temperature operation modes excel here.
Maintenance and Longevity
Cleaning Best Practices
Travel exposes lights to dust, sunscreen, and food residue. Clean the lens weekly with a microfiber cloth—never paper towels, which scratch. For the clip mechanism, a cotton swab dipped in isopropyl alcohol removes grime from crevices. Avoid submerging the light; even water-resistant models have seals that degrade. If the USB port collects lint, use a wooden toothpick (never metal) to gently extract debris. For stubborn marks on silicone grips, a pencil eraser works wonders. Clean contacts on removable batteries with a dry cloth every few months to prevent corrosion, especially in humid climates.
Battery Health Optimization
Lithium batteries degrade fastest when kept at 100% charge or drained completely. For storage between trips, maintain the battery at 40-60% capacity. Avoid leaving the light plugged in overnight; modern chargers prevent overcharging, but heat accelerates cell degradation. If you won’t use the light for months, store it in a cool, dry place—refrigerator temperature (not freezer) is ideal for long-term storage. Every six months, run the battery through a full discharge and recharge cycle to recalibrate the power indicator. For lights with replaceable batteries, consider buying a spare and rotating them to distribute wear.
Storage Between Trips
Don’t just toss the light in a drawer. Engage the travel lock or remove the battery if possible. Store it unfolded to prevent the spring from taking a set and losing tension. Keep silica gel packets in your storage bag to absorb moisture, especially if you’ve traveled in tropical environments. If your light came with a protective case, use it—even for home storage. Check the hinge screws every few months; vibration from travel can loosen them. A dab of thread locker (like Loctite Blue) on screw threads prevents this without making future disassembly impossible.
Common Buying Mistakes
Overlooking Weight Specifications
Manufacturers often list weight without the charging cable or optional accessories. That 3-ounce light becomes 5 ounces once you add the required cord. Check user reviews for real-world weight measurements. More importantly, consider the “carrying weight”—a heavy clip might require a sturdier laptop screen, adding stress to your device’s hinge. For ultralight backpackers, even a 2-ounce difference matters. Always factor in the weight of any spare batteries or protective cases you plan to bring. The cumulative weight of travel gear sneaks up quickly.
Ignoring Charging Cable Compatibility
That micro-USB light seems fine until you realize your phone, tablet, and headphones all use USB-C. Now you’re carrying an extra cable for one device. Standardization reduces clutter and failure points. Also verify the charging port’s orientation—some lights have recessed ports that only accept slim connectors, rejecting bulky braided cables. For international travel, consider whether the light charges reliably from universal adapters with varying voltage outputs. Some budget models lack voltage regulation and can be damaged by inconsistent power supplies common in developing countries.
Underestimating Clip Strength Needs
A clip that works perfectly on your home hardcover might struggle with the thin bezel of a modern ultrabook. Test the clip’s opening width and spring pressure on all intended surfaces before committing. Silicone padding compresses over time; a clip that feels perfect initially might loosen after a month of use. For laptop use, the clip must support the light’s weight when positioned horizontally—some designs rely on gravity to stay in place and fail when clipped to vertical screens. The return spring should engage early in the opening motion, providing grip security even when only partially opened.
Frequently Asked Questions
Can clip-on book lights really provide enough illumination for video calls without creating harsh shadows?
Yes, when positioned correctly. Place the light above and slightly to the side of your laptop camera, angled at 45 degrees toward your face. Use the lowest brightness setting that eliminates shadows under your eyes. Cool white light (5000K-6000K) mimics professional office lighting. The key is diffusion; ensure your light has a textured lens rather than clear plastic. Some models include a “webcam mode” that optimizes beam angle for this exact purpose.
Will these lights damage my laptop screen or leave permanent marks on the bezel?
Quality lights with wide, padded clips distribute pressure safely. Avoid models with narrow metal clips or hard plastic edges. Never clip directly to the screen itself—always attach to the bezel or lid edge. Check your laptop manufacturer’s warranty; some explicitly warn against third-party clips. To be extra safe, place a thin microfiber cloth between the clip and laptop surface. Silicone padding is generally safe, but test on an inconspicuous area first if your laptop has a soft-touch coating.
How do I prevent the light from disturbing others on overnight flights?
Use the narrowest beam angle available and dim to the lowest usable setting. Position the light to create a “light curtain” between you and your seatmate rather than casting light toward them. Warm color temperatures are less disruptive than cool. Some lights include a physical honeycomb grid that restricts light spread—use it. Clip the light to your own clothing or seatback pocket rather than shared surfaces. The goal is creating a personal photon bubble that doesn’t leak.
Are these lights allowed in carry-on luggage through airport security?
Yes, clip-on lights are permitted in both carry-on and checked baggage. The lithium battery capacity typically falls well under the 100Wh limit for spare batteries. However, never pack them with the power button exposed—accidental activation can trigger thermal runaway in rare cases. Use the travel lock feature or pack in a way that prevents button pressure. Security agents may ask you to demonstrate functionality if the device looks suspicious, so ensure it’s charged before travel.
Can I use my clip-on light while it’s charging from my laptop’s USB port?
Most modern lights support pass-through charging, but this depends on power draw. A laptop USB-A port typically supplies 5V/0.5A, which may not be enough to both charge the battery and power the LED at full brightness. USB-C ports provide more power. The light will prioritize LED operation, so it may function while charging slowly or not charging at all. For reliable simultaneous use, connect to a power bank or wall charger that can deliver 5V/2A. Check the manual—some lights disable LED operation during charging to prevent battery stress.
What’s the ideal color temperature for reading physical books versus working on a laptop?
For paper books, warmer light (2700K-3500K) reduces eye strain and creates a cozy atmosphere. This temperature range minimizes blue light that can disrupt sleep if reading before bed. For laptop work, cooler light (5000K-6500K) enhances contrast and alertness, making text appear sharper. Many travelers use 4000K as a compromise setting for mixed use. The key is matching the light temperature to your screen’s native white point—most laptops are calibrated to 6500K, so matching this creates visual consistency.
How long should I expect a quality clip-on light to last with regular travel use?
With proper care, a mid-range light should function reliably for 3-5 years. The LED itself can last 50,000+ hours—over 17 years of continuous use. The battery is the limiting factor, typically degrading to 80% capacity after 500 charge cycles (about 3 years of weekly charging). Hinges and clips may loosen after 2 years of constant adjustment. Premium models with metal construction and replaceable batteries can extend lifespan to 7+ years. Environmental factors matter; humidity and extreme temperatures accelerate wear. Store your user manual digitally—manufacturers often extend warranty coverage if you register the product online.
Is there a significant difference between rechargeable and battery-powered models for international travel?
Rechargeable lights are more convenient and cost-effective for most travelers. However, battery-powered models using standard AA or AAA cells offer unlimited runtime if you can buy replacements locally—crucible for extended remote travel. Rechargeable lithium lights perform poorly in extreme cold, while alkaline batteries handle it better. For international travel, consider power availability: rechargeable suits developed regions with reliable electricity, while battery power excels in developing areas. Some hybrid models accept both, offering the ultimate flexibility. Just remember that spare lithium batteries must be in carry-on luggage only.
Can these lights be used with e-readers like Kindle or Kobo devices?
Yes, but with caveats. E-ink screens are matte and non-reflective, so they actually benefit more from external lighting than tablets. However, the clip must be gentle enough not to crack the e-reader’s plastic bezel. Clip to the device’s case rather than directly to the e-reader. Position the light to avoid glare on the screen’s frontlight layer—some e-readers have slightly glossy surfaces. Battery life becomes less critical since e-readers sip power; you can dim the external light significantly. Warm light temperatures work best with e-ink’s paper-like appearance.
What should I do if my clip-on light starts flickering or won’t hold a charge?
Flickering usually indicates a loose internal connection or low battery voltage. First, fully charge the light and test again. If flickering persists, gently tap the housing—if the light cuts out, there’s a solder joint failure requiring warranty service. For charging issues, clean the USB port with compressed air and try a different cable. If the battery won’t hold charge, it may have entered deep discharge protection; leave it plugged in for 2-3 hours even if no charging indicator appears. For lights over a year old, consider battery replacement. Never attempt to open a sealed unit—this voids warranty and risks thermal runaway. Contact manufacturer support with your purchase date and symptoms; many offer discounted replacements even outside warranty.
