Safety
 

1. Overcurrentprotection
When the current increasing in an exception, power bank immediatelyStart voltage buffer fuction, ensure the voltage in a steady stateat any time., Avoid cause your charging device any damage.
2. Short circuit protection
When there is a short circuit occur in external device, power bankstart Protection function, shut down the supply and avoid shortcircuit 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 thehigh temperatures.
4. Overdischarge protection
When power bank discharge reached the critical point, the circuitautomatic start Protection function and stop discharge.
5. Overcharge protection
Long time charge for mobile power supply or use power bank chargefor the phone. When reach saturation point, system automaticallyshut down, avoiding the overload problems.
6. Overvoltage protection
Long time charge for mobile power supply or use power bank chargefor the phone, When reach saturation point, in order to preventover-voltage, the system automatically turnsoff.

ConversionRate

1. Usually there isinternal resistance in all mobile. and power bank will lost powerwhen you charge mobile because this internal resistance.  wecalled it is Conversion Rate
2. About 8 to 10 hours charge can get the power bank full of powerin normal times
3. charging time depending on charger.the more,the faster
4. the output power is different for every mobile. because mobileinternal resistance is different.
5. All the power bank has Conversion Rate,as well as yourphone,Charge will happens twice energyconversion!
