Tips on Proper Use of Power Banks to Extend Their Lifespan

In our technology-driven world, staying connected is a must, and power banks play a crucial role in ensuring our devices keep running when we're on the go. However, like all gadgets, power banks require proper care to maintain their efficiency and extend their lifespan. In this blog post, we'll explore some effective tips on how to keep your power bank in tip-top condition for as long as possible.

Avoid Pass-through Charging

Nowadays, many power banks feature various ports and promote the ability to simultaneously charge devices while being charged themselves, a function known as "pass-through charging." This process significantly strains the circuitry within the power bank, causing it to heat up quickly, which may not only lead to the device getting warm but could also reduce the effectiveness of its battery. Furthermore, the possibility of inconsistent charging arises due to fluctuating voltage, which, in extreme cases, could even damage the battery of the connected mobile phone. Hence, it is advisable to avoid using the power bank while it is recharging.

Use it Under Proper Environment Temperature

Every electronic device operates optimally within a specific temperature range. The majority of power banks utilize lithium batteries, which function best between 0°C and 55°C. When exposed to temperatures below this range, the discharge capacity of lithium batteries decreases, leading to erratic charging and discharging behavior. Conversely, exposure to excessively high temperatures can accelerate the deterioration of batteries and circuit boards, and expedite the aging process of certain components. As such, it is recommended to use the power bank in environments with temperatures ranging from 0°C to 55°C.

Do not leave it unused for a long time

Should a power bank remain idle for an extended duration, the lithium battery within will gradually deplete its charge. If it is consistently allowed to reach depletion, the battery may enter a low-voltage condition where lithium ions become inactive, leading to a reduction in chemical activity and resulting in a "sleep" state. This status can inflict irreversible "deep discharge damage" upon the battery. Typically, within a timeframe of less than three months, the battery's core capacity may experience significant deterioration.

Use Regularly

To maintain the optimal condition of your power bank, it's essential to use it regularly. Batteries can lose their charge over time, and not using a power bank can lead to decreased battery efficiency. Try to cycle through a full charge and discharge at least once a month.

Some people say that using a power bank too frequently will affect its service life. In fact, this statement is general. Like mobile phone batteries, the lifespan of a power bank mainly depends on the "number of charge and discharge cycles" of its battery core, and a charge and discharge cycle refers to the completion of a 100% complete charge & discharge process.

As the battery core is charged and discharged again and again, the life of the power bank will gradually shorten. Therefore, the biggest component that affects the life of a power bank is the quality of the battery core.

Avoid Overcharging

Do not leave your power bank plugged in longer than necessary. Once it's fully charged, disconnect it to prevent overcharging, which can reduce the battery's lifespan. Many power banks come with built-in overcharge protection, but it's still a good practice to unplug once charging is complete.

Avoid Drops and Impacts

Physical damage can also degrade the internal components of your power bank. Be cautious not to drop it, and consider using a protective case to shield it from impacts and scratches.


By following these simple yet effective tips, you can help ensure your power bank remains a reliable power source for your devices for years to come. Remember, the key to extending the life of your power bank is as much about how you use it as it is about how you take care of it.
