How do I choose a charger?
Of course, the specific depends on your battery capacity, such as the battery is 1000mAh, then there is no need to choose 2000mA "charger".
More than 2000mA can (such as 2500mA), less than 2000mA may not work.
It is best to press the original 5V 2000mA choice, do not seek exactly the same,
Your "charger" marked output 5V 2000mA, indicating a larger battery capacity.
Should be based on your mobile device battery safety time Ah decision.
