Power Bank Buyer’s Guide
How Does a Power Bank Work?
This rechargeable external battery pack allows its users to fully refill their devices. The name itself explains a lot. They deposit the electrical energy a.k.a. ‘power’ in their ‘bank’ and later on allow you to draw it from it and charge up a mobile device. They can do this thanks to a battery located inside a power bank case that has a circuit which in turn controls power flow.
Which Devices Are Compatible With My Power Bank?
If your device is charged via USB the majority of portable batteries are compatible. So this includes all mobile phones such as those from Apple, Samsung, HTC, Blackberry and Nokia, and also the GoPro camera, Kindle reader or Bluetooth headset. If it has a larger capacity, a power bank can also charge laptops and tablets.
How Do You Know if Your Portable Charger Is Fully Charged?
Normally, power banks use a mini USB socket for input, that is charge coming in, and a full-sized USB socket for output to charge your device. If you are not sure which socket is which, we warmly advise you to check the manual for precise instructions. Once you have this straight, connect the cable to the mini-USB socket. Afterwards, connect the USB end of the cable to a power source and all together to a power point. A power source can also be a USB socket on your PC, but in this way charging takes longer. A light indicates when the power bank is fully charged. When it is full simply unplug the power bank.
What Is the Meaning of mAh in Power Bank?
The more milliampere-hour (mAh) the power bank has, the greater the energy it provides. If you would like to charge a stronger machine or two devices at once, you need a stronger external battery. A small trick that will speed up the process is to leave your phone alone. If you are listening to music while charging it may seem like the device is never charged because of the ongoing energy consumption.
How Long Does It Take for a Power Bank to Charge?
To get a picture, let’s say that an external battery of 1500mAh needs about the same time to charge as a typical smartphone. With an increase in the strength of the power bank, the charge time increases proportionally. If you want to fully fill your portable charger, arm yourself with a little patience.
How Many Times Can a Specific Power Bank Recharge My Device?
It's basic math. For example, if your device has a 2000 mAh battery, a 6000 mAh power bank will suffice for about 3 charges. Find the capacity of your device in the “about phone” section in the settings.
