Tech TalkPower bank battery technology
Whilst the management of the battery charging and discharging is key to the way the power bank works, so too is the battery technology employed.
There are two main technologies that are used:
Lithium-ion
Lithium polymer
How Power bank Works
Powerbanks are becoming popular these days as our gadgets or devices were all getting smarter & versatile tools in our daily lives specially for various types of communications such as calls,sms,emails and other task,and these smart devices (smartphones & tablets) needs more power for them to work and last for a day as they should be. Normally the devices that needs a back up power are the smartphones & tablets these days.And most of us individually owns one.But not all people knew how powerbank works literally.And some sellers just don't explain on how their Powerbank works.And many people just end up buying the wrong specifications of powerbank that suits the need of their devices (such as smartphones & tablets).That's the reason I made this and compiled some facts gathered from different manufacturers and blogs site ,and made it into one instructables that may help some DIY'ers who planned to build their own powerbank or just buy the right one.
How It Works? What Type of Powerbank to Choose?
Power Banks are all the rage, they came in various shapes and sizes.,but what are they for? We explore their potential, and how to choose the right one.
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,
How long a Power Bank can retain its charge when not in use.
The answer to point one can differ between models of Power Bank, their internal components and the quality of their manufacturing. We try not to stock Power Banks which have fewer than 500 charge cycles in them.
For example, leaving a Power Bank in the car where the temperature can fluctuate greatly over time can shorten its lifespan.
What does mAh mean?
Batteries common to mobile devices and Power Banks are rated on their ampere-hours, measured in milliamps to create non-decimal numbers. The mAh ratings denote capacity for power flow over time.

•How do I charge a Power Bank?
Most commonly, a Power Bank will have a dedicated input socket for receiving power. This power can come from a USB socket on your computer, but may charge faster when using a wall socket adapter. We most often see Power Banks use a Mini or Micro-USB socket for charging, and full-sized USB sockets for discharging. On very rare occasions, Power Banks can use the same socket for input and output, but this is rare and should not be assumed of any Power Bank, as trying to force power into an output can damage the battery. Always check the manual for specific instructions if you're not able to find a clearly marked input socket.
Depending on the capacity of the Power Bank and its current charge level, it can take quite a while to fill up.
