Statement: this product all electricity tested to ensure that the function is normal, but it has a very small probability of USB virtual welding.If there is such a failure to repair welding, trouble or do partial refund processing, can't do replacement!

The basic parametersThe input voltage range: 5 ~ 6 vOutput voltage: 4.2Charging current: 1 a

Function is introducedWhen the charging current after finally float charging voltage drop to 100 ma, will automatically terminate charging cycle.When the battery voltage to 4.05 V (roughly corresponding to the battery capacity of 80% to 90%), the charging cycle againThe beginning.When when the battery voltage is lower than 2.9 V, there will be 100 ma of current of battery charging.

Product size: 12.5 * 15.5 * 3.5 mm (excluding Micro - USB prominent 1 mm)
