Specification:
1.REMAX Power Bank Quality: A+++++
2.Output Current: 5.0V / 1000mAh~2100mAh(max)
3.Input Voltage/Current: 5.0V / 1000mAh
4.Package marked theorectical value capacity is 30000mAh
5. Normal capacity: 20800mAh (you know that all the mobile phones and cables have internal resistance，so when you charge your phone by the power bank，it will consume some power，we called it conversion rate，internal resistance is different，the output capacity is different.Hope you can understand，thank you *_*.)
Note:
Number of charges equals = (Power capacity of Power Bank* battery conversion efficiency* phone inner core conversion efficiency (80%))/ the capacity of mobile phone battery
Take for iPhone 6 for example:
Capacity of Power Bank: 20800mAh
Power bank conversion efficiency: 3.7V/5V
Phone inner core conversion efficiency: 80%
The capacity for iPhone6 battery: 1810 mAh
(20800mAh x 3.7/5*80%)/1810=6.8
So this power bank， the total Number of Charger for iPhone 6 is 7 times.
5.Product dimension: 160x 80 x 22mm

How to use
1. Usually there is internal resistance in all mobile phones and USB cables. As a result，the power bank will lose power when you charge your mobile phones. we called it is Conversion Rate
2. Normally it takes about 10-11 hours to charge the power bank full，but if you pay your phone at the same time，it will take more.
3. The output power is different among mobile phones because the internal resistance is different.
4. All the power banks have Conversion Rate，when you charge your phone，there will be twice energy conversion!
