How Long Does a Power Bank Last?

How Long Does a Power Bank Last

Power banks are portable devices for charging phones on the road. Their compact designs are convenient. They also support most smart devices, which includes phones and tablets. How long do power banks last? This is a common concern for first-time shoppers. We do not have a definite answer. However, here are a few attributes that affect the longevity of power banks:

Power cells

To store charge, power banks use power cells. These are of different types. Nickel Metal Hydride (Ni-MH) power cells are traditional. Even though cheap, their low-powered designs often fail to satisfy the needs of most people. They are also sensitive to heat and other elements, which shorten their lives significantly. If you have a power-thirsty device, a Ni-Cad power bank might let you down. Lithium-ion (Li-ion) and Lithium polymer (Li-poly) power banks are powerful devices that device longer. These cells store more charge than Ni-MH cells do. Their stable designs also last for long.

Age of Power Bank

Depending on the type of cells your preferred power bank uses, you will get between 200 and 1000 recharge cycles from it. This varies greatly between devices. As power banks age, they also generate less juice than when they were new. For instance, most Li-ion and Li-poly power banks have a self-discharge rate of 2% per month. As these cells age, this increases the between 3% and 5% depending on their type and the quality of care they get. If you store your power bank in a hot area, for instance, you will get significantly less power from it over time.

Battery Capacity

Power banks are of different types. They also come in different sizes with different capacities. To know whether your brand of choice will serve you well for long or not, check the latter attribute. High capacity power banks last longer than low capacity ones do. A reputable branded model with a capacity of 1600mAh, for instance, can charge the power-hungry iPhone up to 10 times. Moreover, you do not have to recharge it many times to achieve this. This lowers its risk of developing the Memory Effect. With an 800mAh power bank, however, this drops by almost half.

Discharge Rate

Most power banks have both 2.4A and 5A USB discharge ports. These charge different devices. They also have different discharge rates, which affects the longevity of power banks. The 5A discharge port uses more power than the 2.4A one. If you have a power-thirsty tablet and other devices that need this output, your power bank will drain faster. To keep your devices powered, you have to recharge it many times. This degrades cells faster, which in turn lowers the lifespan of your power bank.

Conclusion: Power banks are reputable devices that have helped people to stay connected off road. Even though simple, they have powerful systems. They are also safe and designed to charge most smart devices well. To determine the longevity of your product of choice, you should know a few things. First, the cells and age of a power bank affect its performance and longevity. Second, factors such as the capacity of a power bank and its discharge rate have a direct effect on its lifespan.
