Description:
Portable power bank aka: mobile power charging treasure, they are actually from a stable power supply (mainly power supply, enough to provide a stable operating voltage and current) with the necessary constant current, limited pressure, limit and other control circuits .
Portable power bank can be divided into travel charger, docking charger, USB charger and maintenance charger, general users are mainly two front contact. And the market is the largest selling travel charger.

Chargers (refer to line charge) marked on the output parameters: for example, output 5.0V / 1A, output 5.0V / 1500mA-11200 ...... refers to the internal power supply of the relevant parameters.
Standardized charger products are marked with the use of range, the output voltage and output current and other technical parameters. Conditional, it is available when purchasing a multimeter to test the output load voltage value and output short-circuit current of the charger to determine whether the actual data is consistent with the standard technical parameters.
Portable power banks can mix different brands, as long as the interface, the output voltage and current can be universal agreement.
2014 hot sell 30000mAh portable power bank for smartphone and tablet is a good use of the charger.
