For smartphone users, power banks have become a must-have item. Power banks used to provide basic USB 1 Amp charging a few years ago. The newest powerbanks with rapid charging technologies like QuickCharge or USB-C PD charging, on the other hand, are rather pricey.

For example, power banks like the Anker PowerCore 20000 Speed that provide the quickest 18 watt USB PD charging for iPhone 12, 11, XR, X, and iPhone 8 demand premium pricing.

Power bank Li-ion or Lithium Polymer batteries have a limited life lifetime of approximately 500 charging cycles after which they begin to deteriorate.

Here are some pointers to help you take care of your power banks and get the most out of them.

Charge Power Banks to 40% before storing them.

Many people keep their power banks completely charged or at extremely high levels of energy. This rapidly depletes Li-ion/Li-Po batteries and should be avoided at all costs.

Many users also keep drained power banks for a long time after a journey, merely charging them before their next travel. This should also be avoided since leaving batteries in a depleted condition for an extended length of time essentially destroys the battery in a matter of months.

For contemporary Li-ion or Li-polymer batteries, the optimal charge for storage is about 40 to 50 percent. As a result, you should avoid discharging the powerbanks below this level for extended periods of time.

If your powerbank is low when you return from a vacation, you should recharge it until it is half full (2 lights blinking in a 4-light battery status indicator). before keeping it for an extended length of time.

Similarly, if your powerbank is almost full, “bleed” some energy away by charging your phone until the battery status indicators indicate approximately 50% charge.

Powerbanks should be kept cool during use and storage.

Chemical processes are used to generate energy in powerbanks, and like with other chemical reactions, greater temperatures result in quicker reactions. Powerbank deterioration is also temperature sensitive, thus storing them in a hot environment would quickly deteriorate them.

Keep the powerbanks at room temperature if possible (60 to 80 degrees fahrenheit or 20-28 degrees celsius). Also, avoid keeping powerbanks in enclosed glass cases that are exposed to sunlight or in excessively hot work environments.

During usage, the best-kept-cool criterion also applies. A heated powerbank will rapidly discharge.

Keeping powerbanks cool does not imply that they should be refrigerated or kept in frigid temperatures. Freezing temperatures will completely destroy the powerbank. A powerbank that is excessively cold will take a long time to charge.

Pass-Through Charging is not recommended.

Pass through charging refers to the practice of charging your gadgets while the powerbank is being charged. This quickly depletes the batteries and should be avoided. For this reason, most contemporary powerbanks block passthrough charging. Even though your powerbank supports passthrough charging, it is advised that you only utilize it when absolutely required.

Charge your devices using short, high-quality cables.

Poor quality and lengthy cables waste a lot of electricity and decrease the amount of charge that can be used in a powerbank. Long connections result in significant voltage losses, reducing charging current to a trickle. In fact, one of the most common causes for customers complaining about their bank’s bad performance is that they charge their gadgets using lengthy cords.

When charging your devices from powerbanks, it is strongly suggested that you select high-quality cables that are as short as possible. Simply replacing a lengthy connection with a short, high-quality cable may sometimes quadruple the powerbank’s useable battery capacity.

Powerbank charging cords should be at least 6-inches or 12-inches long. Do not exceed a length of 3 feet. To charge your phone, you don’t actually need 6 foot cords. Also, make sure you’re using reputable and high-quality cable brands.

Anker Powerline+ is a great brand for Android users. Anker Powerline II is one of the finest brands available for iPhone users.


Discharging a power bank is an important step in the life of your battery. It will help to increase the power bank’s life and efficiency. Reference: how to discharge a power bank.
