how long can a power bank last

No matter what kind of digital products we buy, we will surely be concerned about how long they will last. As to a power bank, the working life is also a reflection of the quality of the product. It could be dangerous if you accidentally use the upper limit of its usage life.

How Long Can a Regular Power Bank Last?

The average service life of a power bank is about 3 years across all portable charger brands. When surveying Zendure original customers from 2013, many responded they still have their original Zendure power bank! We are pleased we perform far beyond the industry standard. 

So what determines the battery life? The biggest component that can affect the working life of the battery is the battery cell. The battery cell is usually 18650 or polymer. Most of the instructions of the battery charge-discharge cycles are about 500 times, and some are about 800-900 times. Every full charge and discharge of the battery should have a certain loss to the battery.

Take the charging capacity of 5000mAh and 500 times charge-recharge as an example; if the portable charger is charged every two days, it can be used for 1000 days, about 3 years. The second component that can affect the working life is capacity. In the same case, the larger the capacity, the more power it can provide to meet your devices demand, and the fewer charge-discharge times it needs, so the longer it will last.

Portable charger safety protection

If you purchase a genuine quality power bank and you pay more attention to maintenance when you use it, generally, it is OK to use it for more than two or three years. However, a power bank without quality assurance would go wrong at any time. Therefore, it is recommended to buy a power bank with quality assurance and from a company with a good reputation.

Zendure provides a two-year warranty on all portable chargers and charging accessories.

In fact, an excellent quality portable charger will also become less durable if you do not use it properly. So what should you do to extend a power bank’s working life?

Ways to Extend a Power Bank’s Life:

  1. Try to keep the battery power near the half-full state. It’s said the best use habit is to charge the battery after using 50% of the battery, although the charging times are increased, the damage to the cell is lower.
  2. A power bank does not do well in cold and hot environments, so please pay attention to the temperature.
  3. Waterproof. To be clear, a power bank does not have a waterproof function normally, so it is easy to make the product unusable once it is flooded.
