DrPhone RS8 30000 mAh Powerbank – 10-fold Protection - Charge 3 Devices - Qualcomm 3.0 - USB-C 9V 18W Fast Charge - White

30,000 mAh: The Sense 8 has a large capacity of 30,000 mAh. This gives your devices several full charges via the power bank. A must-have for unlimited gamers, camping, hiking and all kinds of parties.

18W Fast Recharge USB C Input & Output: it takes only 11 hours to fully charge the 30,000 mAh power bank with an 18W USB C wall charger. Unlike other power banks, the charging process takes much longer. Because the USB C is both input and output, you can charge the power bank with a power of 9V 2A.

With 3 inputs: Micro-USB, lightning and Type-C offer great convenience when charging this power bank with one of these 3 commonly used cables.
Note: 18W wall charger is NOT included.)

This portable charger can therefore be charged with any of the 3 types of cables (Micro USB / lightning / Type-C) you use for your device. (the lightning / Type-C cables are NOT included, the micro USB cable is INCLUDED)

Qualcomm 3.0: charges faster via the Qualcomm 3.0 port. This only works if the supported devices allow it. Compared to a normal port, this QC function port charges your device much faster, 4 times faster than conventional chargers. 2 USB outputs allow you to charge your devices simultaneously.

Safety and reliability: the built-in intelligent safety system provides full protection for you and your devices, including overheating, overcharge, overcurrent, over-discharge and short circuit protection.

Low Power Mode Charging: The low power consumption charging mode is also called the energy-saving mode. In this mode, the power bank keeps the output on for about 2 hours and the indicators flash in turn. It is recommended to use this mode to charge low power consumption accessories such as Bluetooth headsets, bands and watches. You can activate this by pressing the power button on the side twice in a row.

Explanation about mAh:
Difference between battery capacity and actual capacity
One third of the capacity is lost. The technical explanation is complicated, but the rule is simple: the actual capacity of a power bank is about two thirds of the stated capacity. The rest disappears during power conversion or is lost during charging, especially as heat. Power banks with a battery of 10,000 mAh or 20,000 or 30,000 mAh actually have only 6,660 mAh or 13,330 mAh or 17,500 mAh capacity.

That power banks have two thirds of the stated capacity is largely because the current must be converted. For example, the voltage of the power bank battery is 3.7 ampere, but to charge a smartphone or tablet the power bank must raise the voltage to 5 ampere. By raising that voltage, only 7,400 mAh remains from 10,000 mAh, a quarter less. This applies to every power bank, regardless of capacity or quality. During charging, about 10 percent of the remaining energy is lost. That 7,400 mAh is then only 7,400 x 0.9 = 6,660 mAh. Much of that energy is lost as heat: that is why your smartphone often gets warm during charging.
