You also have the ability to check the remaining capacity throughout the day at any given time and all you have to do is press the power button and get a quick LED reading. The unit powers off automatically if no load is detected within a 30-second period.
Power bank serve as an ‘extra battery’ or external charger for your phone or other electronic devices.
2) Where is power bank made from?
Majority of the power banks in the market are actually made in China.
3) How do I charge the power bank?
You can charge your power bank via the charger that came with your phone, computer usb port or using other power bank
4) How long do I need to charge the power bank?
It’s depending on the REAL CAPACITY of the power bank. The larger REAL CAPACITY, the longer charging time may required. Different charging methods may result different charging time as well. Charging with the original charger will be faster than charging with computer usb port.
5) Why sometime I need longer time to charge the same power bank?
Even though using the same charging method, the charging time may be differ due to environment,temperature, power flow and etc

6) What is mAh?
mAh mean milli Ampere Hour, the capacity of the power bank is measure with mAh
7) A 12000mAh REAL CAPACITY power bank, able to charge a 1500mAh capacity phone for 8 times full?
This is a common mistake make by most of the people. For rough calculation of the total charge time, kindly use this formula
REAL CAPACITY * conversion rate * phone battery health / phone capacity = total charge times
EXAMPLE: 12000 x 0.8 x 0.8 / 1500 = 5.12 charge times (0.5-1 times plus minus)
8) What’s conversation rate?
Conversation rate is the remaining percentage of the battery after the battery lost in heat or PCB operation.
9) What’s phone battery health?
In simple, it’s mean how‘healthy’ your phone battery is. Phone battery storage capacity will be lower and lower. That’s also the reason why our phone can last longer when it’s newly bought than after 3-6 months we used it. Different mobile phone models also will affect the calculation as some phone drain battery faster than the other.
10) What’s PCB?
PCB means Printed Circuit Board,its control all the operation flow inside the power bank. A good quality PCB will allow the power bank to charge more and have better durability
11) What’s 18650 power bank and what’s Li-Polymer power bank?
The common type will be 18650 and a better type will be Li-Polymer
12) What’s the different between 18650 and Li-Polymer?
– 18650 size and dimension are fix. Li-Polymer size and dimension are flexible.
– 18650 produce more heat. Li-Polymer are much more safer
– 18650 are cheaper. Li-Polymer are more expensive
– 18650 have higher self discharge rate.Li-Polymer have a very low self discharge rate
– 18650 battery durability will drop faster. Li-Polymer battery capacity are more durable
13) What’s the common mAh use in 18650?
Common mAh use in 18650 is around 1300mAh to 2200mAh.
Let’s face it. As marketers we sell these things but do we really know what they are and how they work?
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.
