DrPhone HyperCell3 - 30,000 mAh Power Bank 2A Charger - 2 USB Ports with LED Light & LED Display Screen - White

Are you often travelling or on the go and have no access to a power source to charge your phone or tablet? DrPhone® introduces the HyperCell3 Power Bank. The perfect solution to safely and quickly charge tablets, smartphones and all your other devices, and with the built-in LED lamp you can also use the power bank as a torch.

The HyperCell3 itself (input) can be charged using a USB-C, Micro-USB and Lightning cable. You have the option to charge two devices simultaneously with the HyperCell3. The output of this power bank is 2A. One with an output of 1.5V /2A & the other with 2.5V/2A

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

The HyperCell3 features a Digital Display so you can easily see how much power the HyperCell3 has. Depending on the type of smartphone, you can charge a tablet and/or smartphone several times.

- Large capacity (30,000 mAh)
- Safe and fast charging
- Charge the HyperCell3 with 3 types of charging cables. (USB-C, Micro USB or Apple lightning)
- Charge up to 2 devices simultaneously.

Note: Input is only to charge the power bank itself. Output is to charge both the power bank and the smartphones.

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 the conversion of the power 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 only have 6,660 mAh or 13,330 mAh or 17,500 mAh capacity.

The fact that power banks have two thirds of the stated capacity is largely because the power has to be converted. The voltage of the power bank battery is for example 3.7 ampere, but to charge a smartphone or tablet the power bank has to increase the voltage to 5 ampere. By increasing 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.
