About How to Choose a Power Bank for Your Phone

First, we’ll begin by explaining how a power bank works. A portable power bank stores electrical energy supplied by an outlet and allows you to “deposit” that energy later into a mobile device. Power banks have to be charged, sometimes for a considerable period of time, but will store enough electrical energy to fully power a device several times over. It should be noted that power banks will always experience loss due to resistance, so the full capacity of the power bank is not transferred to the device, and this is a factor when we calculate and estimate how many times a particular device can be charged. Additionally, the lower the charge on your device, the more the portable power bank has to work to recharge it. So, ideally, you do not want to wait until the device is fully depleted of battery life before using a portable power bank.

Almost any device that is USB charged can be used with a portable power bank provided you remember to keep the power bank charged! It is best to remove the power bank from the charge as soon as it is full and most have an LED indicator to display full capacity. Some come with an “auto cutoff” feature as well.

When deciding how to choose a power bank for your phone, check your devices for their battery capacity, which is measured in milliamp hours (mAh). As long as your portable power bank exceeds the mAh number on the device, you will get a full charge out if it, if not several. Be sure to consider if you plan to charge multiple devices. If this is the case, you will need a portable power bank with more than one output to charge the devices simultaneously. Obviously, these models can be more expensive, but they can also save precious time during travel.

You will also need to check compatibility with the portable power banks to make sure your devices are included or you can compare its specs to your existing charger. You do not want to find out in the midst of travel that your cable and the power bank produce a very slow charge. Additionally, the output voltage of the power bank should be equal to or higher than your device.

A general guideline for the charge provided by varying mAh batteries is as follows:

  • 1500 mAh: typically one full charge of a cell phone
  • 5200 mAh: typically two full charges of a cell phone and a tablet to 50%
  • 10000 mAh: typically four full charges of a cell phone and a tablet to 100%

Higher mAh units are available as well. These will be more expensive options, but possibly beneficial to those with numerous devices to charge during travel.
Environmental conditions can affect the lifespan of a portable power bank and you should keep this in mind as you decide to invest in one. For example, if you plan to travel for long periods of time in extreme weather conditions, this may have an impact on the long-term durability of the power bank you choose.
