Safety

1. Overcurrent protection
When the current increasing in an exception, power bank immediately Start voltage buffer function, ensure the voltage in a steady state at any time., Avoid cause your charging device any damage.

2. Short circuit protection
When there is a short circuit occur in external device, power bank start Protection function, shut down the supply and avoid short circuit damage.

3. Overheat protection
When the power bank work long in high temperature environments (Exceed 60 degrees), Power bank will not be dangerous due to the high temperatures.

4. Overdischarge protection
When power bank discharge reached the critical point, the circuit automatic start Protection function and stop discharge.

5. Overcharge protection
Long time charge for mobile power supply or use power bank charge for the phone. When reach saturation point, system automatically shut down, avoiding the overload problems.

6. Overvoltage protection
Long time charge for mobile power supply or use power bank charge for the phone, When reach saturation point, in order to prevent over-voltage, the system automatically turns off.

Package Included:

• 1x 20000 mAh REMAX power bank
• 1x USB cable
• 1x Retail Box

(The retail box will be changed sometimes according to the factories)

Conversion Rate

1. Usually there is internal resistance in all mobile. and power bank will lost power when you charge mobile because this internal resistance. we called it is Conversion Rate
2. About 10 to 12 hours charge can get the power bank full of power in normal times
3. Charging time depending on charger.the more,the faster
4. The output power is different for every mobile. because mobile internal resistance is different.
5. All the power bank has Conversion Rate,as well as your phone,Charge will happens twice energy conversion!
