Product tester


The Anker PowerCore II is a very compact and high-quality power bank. It convinces especially by its short charging time thanks to its Quick-Charge function and is able to supply 9 V and 12 V devices. The low usable capacity as well as the lack of a possibility to be charged by itself while charging another device are negative aspects. In addition, the Anker power bank has only one output. But if that does not bother you, this product is a good power bank.


  • Short charging time thanks to quick-charge
  • Compact design
  • Can supply 9 V and 12 V at the output


  • Only one output
  • Only 78% of capacity usable

Compact power bank, but only one output and only 78% of the capacity usable.

Special feature

The Anker PowerCore II is the only one of the power bank with 10.000 mAh that I have tested that has a "Quick-Charge" function and can also charge 9 V and 12 V devices. But it's also the only one with only one output.


With its very compact, cuboid design, the Anker PowerCore II fits well in your hand and also fits easily in your trouser pocket. While inlet and outlet are located on the top, the button with the integrated 8-LED charge status indicator is located on the front. I couldn't find any flaws in the workmanship.


The power bank can be charged with 5 V (2 A) or 9 V (2 A) via the Micro-USB input. Consumers with 5 V (3 A), 9 V (2 A) and even 12 V (1.5 A) can be connected to the USB output.


Setup of the capacity measurement
Setup of the capacity measurement

Since power banks never have their full capacity available, I measured the usable capacity of the Anker PowerCore II by discharging it via a resistor and recording the power. For this test I have set a current of 2 A. The measured capacity is about 7.840 mAh. This corresponds to 78 percent of the stated capacity of the manufacturer.

You can see the power output during the discharge in the following graph:

Power output during discharge

From the measured values you can see that the power of the Anchor PowerCore II remains constant throughout the entire discharge process.

Charging time

Discharge heat generation
Discharge heat generation

The Anker PowerCore II is the only 10.000 mAh power bank with Quick-Charge. Therefore I loaded it with a Quick-Charge power supply. The charging time with Quick-Charge is about 3:30 hours. With a standard power supply it takes 5:45 hours to charge.

Heat production

Both during charging and discharging, I noticed minimal warming of the Powerbank with our thermal imaging camera. The higher temperature is reached during discharging and amounts to approx. 32 °C. I measured a temperature of 31 °C during charging.

Short-circuit behaviour and overload protection

A short circuit can damage the power bank and, in the worst case, lead to a fire. Such a short-circuit can be caused by a damaged cable, for example. In order to investigate the behavior of the Powerbank in such a case, I intentionally short-circuited it. The Anchor PowerCore II switches off immediately and is still functional after the short circuit.

I also investigated the behavior of the Anchor PowerCore II in case of an overload. First I increased the current consumption of the connected load until the power bank switches off.

According to the manufacturer, a maximum current of 3 A is permissible at 5 V. In my test, the power bank switched itself off at a current of 3.1 A. The current is not allowed to exceed 3 A.

Drop test

If the power bank accidentally falls to the ground, this is no problem with the Anchor PowerCore II. I dropped the power bank in our office from a height of one meter onto the hard carpet. No external damage was visible afterwards and the Powerbank still worked perfectly.

We have evaluated almost 400 reviews on the Internet. In summary, it can be said that about 85 percent of buyers are satisfied (4 stars) or even very satisfied (5 stars). Partially (2 stars) or completely dissatisfied are almost 10 percent of the users. The average score at the time of the evaluation was 4.5 out of 5 stars.

Summary: 85% positive and 10% negative ratings

The following points were positively noted:

  • Good processing
  • Bag included in delivery

The following points were noted negatively:

  • The long loading time of the power bank
  • Only one USB port
