Safely Caring for, Using, and Disposing of Power Banks

Although not infinite, lithium-ion batteries can last longer with proper care.

Power banks are powered by lithium-ion batteries which will eventually wear out after numerous charges and long use. As they age, their efficiency and capacity diminish, and potential risks grow. Proper maintenance can extend the lifespan of your power bank and ensure its safe use. If your device has been in use for some years, it might be time to look for signs of wear and plan proper disposal.

The likelihood of a power bank causing a fire due to a thermal runaway is uncommon. However, if it occurs, these fires are severe, sometimes explosive, and challenging to control. For instance, Anker had to recall over a million outdated units due to such issues, despite having only 19 incidents reported, which still caused injuries and property loss exceeding $60,000.

Signs of a Dying Power Bank

Detecting when your power bank is nearing the end of its service can avoid failures and minimize fire hazards. A proactive approach in handling and operating it correctly can also mitigate these risks.

Choosing brands recognized for quality may ensure your power bank uses better components, minimizing manufacturing defects. While cheaper options might attract you, the compromises made to slash prices might result in performance and safety setbacks.

Extending Battery Life

Higher capacity models, such as those with 20,000mAh over a modest 5,000mAh, typically endure longer because the load is distributed over more cells, alleviating strain and lengthening lifespan.

Thermal runaway issues relate to heat exceeding what a battery can discharge, leading to uncontrolled energy release. Avoid leaving power banks in extreme temperature environments to prevent overheating-related problems.

Opt for cool, dry locations to store your power banks. Resist clustering them too closely, as a faulty one could precipitate overheating in others.

When to Retire Your Power Bank

Immediately retire and properly discard any power bank that has been physically compromised, whether by puncture, drop, or other damage, as internal battery disruptions might not be visibly apparent.

Based on Anker's guidelines, to extend life, charge the bank only to half or three-quarters full, not letting it deplete fully before the next charge. Avoid charging another device simultaneously to sidestep heat build-up and undue stress.

Software Updates

Some advanced models allow for firmware updates that can enhance performance or correct bugs affecting durability. Verify with the manufacturer's site whether updates exist for your device.

Recognizing Performance Decline

Tell-tale signs of end-of-life include protracted recharge times and reduced device charging frequency. Extreme heat or perceptible swelling also signals possible battery issues.

The protective casing in lithium-ion batteries prevents harmful leaks and guards internal elements. With age or excessive heat, gas build-up can swell the case, making it visually evident and necessitating immediate attention.

Checking for Recalls and Proper Disposal

Regularly checking manufacturer's websites for recalls on your power bank is prudent. Disposing of power banks in regular trash or recycling is hazardous and improper.

Retailers such as electronics stores often have recycling programs though with limitations—make inquiries first. Compliance with local regulations is crucial when disposing, especially for units recalled or showing aging features.
