Anker PowerCore Edge
Battery Capacity: 20000 mAh
Output current: max. 3 A
The high amperage enables rapid battery charging of power hungry devices such as iPhones and iPads.
Modern smartphones with very large screens like Samsung Galaxy Note and its successor models can be repeatedly fully charged.
Because each device only draws as much power as it needs, you can also invite other mobile devices so – which goes as soon as the power supply at home.
The capacity is sufficient for about six Smartphone battery charges and additionally for several bluetooth headset battery charges. Only then the power bank must itself back up to twelve hours to the socket (charging time depends on the power supply. Recommendation: Anker 36W 5V/7.2A 4 Port USB Charger).
To save batteries you should avoid that they become completely empty and never fully charge them to 100%. Therefore, the charge overnight is optimal.
Apple's standard power supply (5 watts) might reach overnight 80%, so it loads hardly too long.
