Some consumers are always concerned about the performance parameters of power bank product specifications should be rated output, output power and life.But it's not right.

Rated output: Rated output voltage and current ratings. Due to a variety of digital devices, input voltage and current are not the same. Power bank supply rated output voltage range and current value will define the scope of application of the product. For example, if the rated output is 5.0V / 6.0V, maximum 0.5A: suitable for most MP3, Bluetooth headsets, cell phones, digital cameras, CD players, video machines charging input voltage; rated output 8V-20V, maximum 2.5 A, that the product is suitable for some of the needs of high-voltage digital cameras, most digital cameras, portable DVD and laptop. If the rated output, including the first two of the range, that universality on the broader scope.

The power bank digital equipment is technically applicable emphasized accurate voltage and current output, to protect the product from overcurrent overvoltage damaged. Scope blind pursuit of some perfume power bank ...
... products, increase the voltage range, but the the a rough circuit protection design and workmanship and choice of materials inferiority, can not guarantee the accuracy of the output, may cause great harm to the applicable equipment.

Capacity: usually MAH (mAh) or WH (watt) to represent the size of the energy (AH * voltage = WH 1AH = 1000MAH) power bank can be stored. The higher the capacity, the more the number of digital equipment charge applicable or support a longer life. For example, if the applicable digital equipment battery 700MAH, capacity 2200MAH power bank can charge 2-3 times, while 4000MAH can reach 5-6 times, of course, to be considered part of the circuit and the internal resistance of the wire.
Market consumers usually choose products based on the capacity size, this is a very immature behavior. First, the capacity is not deterministic, irregular products usually marked large capacity, but a lot of the actual fundamental difference. Secondly, greater capacity on behalf of the security requirements of the higher. Safety and quality battery products is critical, the battery explosions News endless. Should choose the right of regular strength vendor and market products for various certification guarantees.
Life: power bank charger usually to maintain 70-80% of electricity can be recycled more than 500 times, there is the decision of lipstick power bank main.

Hope you get it.
