How to Choose the Right Power Bank for Your Device

Power banks, also known as external batteries, are great accessories for anyone on the go. They allow you to charge your tablet or smartphone battery from anywhere. They are also lightweight and easy to carry, making them ideal for anyone who loves the outdoors. However, it is important to know how to choose the right power bank for your device.

First, you need to know what size battery your tablet or smartphone uses, as well as the charger specifications. To find this look on your device’s charger or battery. If you can’t find it there do a quick Google search for your device type.

Next to “Output” you will see 5.2V and 2.4A. This is the output voltage for your charger.


Once you know this information do your research. The power bank you choose must have the following:

  • At least 1.5 times the size of your device’s battery.
  • Provide output voltage equal to or higher than the voltage of your device’s charger.

This will ensure the power bank has the ability to charge your tablet or smartphone completely at least once. The more mAh the power banks boasts, the more charging capacity it has. Typically a power bank with 3850 mAh could charge the iPad Pro above 80 to 90 percent. So the more mAh the bank has, the more times it can charge the device. If the power bank doesn’t have the right output voltage, then it won’t be able to charge your device.

If you have more than one device look for a power bank that offers multiple outlets and attachments. This way you can charge multiple devices at one time using the same power bank.
