What is a Power Bank and what can they charge?
Portable Power Banks are comprised of a special battery in a special case with a special circuit to control power flow. They allow you to store electrical energy (deposit it in the bank) and then later use it to charge up a mobile device (withdraw it from the bank). Power Banks have become increasingly popular as the battery life of our beloved phones, tablets and portable media players is outstripped by the amount of time we spend using them each day. By keeping a battery backup close by, you can top-up your device(s) while far from a wall outlet.
The Power Banks we're talking about are good for almost any USB-charged devices. Cameras, GoPros, Portable speakers, GPS systems, MP3 players, smartphones and even some tablets can be charged from a Power Bank - practically anything that charges from USB at home can be charged from a Power Bank - you just have to remember to keep your Power Bank charged, too! Power Banks may also be known as Power Stations or Battery Banks, too.
What types of Power Banks are there?
-Three major types of Power Bank found on the market today:
1. Universal Power Bank. They come in many sizes and configurations which can be tailored to your device requirements and to your budget.
2. Solar-Charged Power Bank. They have photovoltaic panels which can trickle-charge the internal battery when placed in sunlight. Solar charging isn't fast, so they can usually charge via cable as well.
3. The third type of Power Bank is the older-style battery phone case. While they can be handy, this type of Power Bank has very narrow device compatibility.
