Anker 533 Power Bank – 30 Watt, 10,000 mAh with USB-C

Anker is also introducing the Anker 533 Power Bank at IFA 2023 and Bibbuzz can provide its own impression using a preliminary sample. The new power bank offers a capacity of 10,000 mAh, charges mobile devices via USB-C with up to 30 watts and uses the integrated USB-C cable as a carrying strap.

2 × USB-C, 1 × USB-A and integrated cable

In contrast to the newly introduced Anker Nano Power Bank (test), the Anker 533 Power Bank not only has two USB-C ports, but also a USB-A socket, so it offers a total of three charging ports.

While USB-A and USB-C are each implemented as sockets, the power bank also offers an integrated USB-C cable that snaps into place on the power bank and is held magnetically, thus also serving as a carrying strap.

The battery in the power bank consists of two cells with 5,000 mAh each (36 Wh/7.2 V), at 5 V this results in 5,900 mAh.

USB PD with 30 watts

The power bank supports USB Power Delivery with up to 30 watts. However, these can only be accessed via the two USB-C ports. The USB-A port supports a maximum of 22.5 watts with PowerIQ 2.0.

It should be noted that the Anker 533 Power Bank can provide a maximum of 24 watts when using multiple USB interfaces at the same time.

The two USB-C ports support the following voltages:

  • Charging: 5V/3A, 9V/3A, 15V/2A and 20V/1.5A
  • Discharge: 5V/3A, 9V/3A, 10V/2.25A, 12V/2.5A, 15V/2A and 20V/1.5A

The power bank can be charged with a maximum of 30 watts via the two USB-C ports.

The USB-A port, however, supports the following voltages:

  • Discharge: 5V/3A, 9V/2A, 10V/2.25A, 12V/1.5A

As mentioned, the power bank cannot be charged via the USB-A port.

TFT display for battery level and remaining time

An integrated TFT display in the power bank, which can be activated at any time using a small button on the top, shows the current charge level of the power bank and the expected battery life based on current consumption. When charging the battery, however, the screen shows when the power bank is expected to be fully charged at the current charging speed.

However, this display of the remaining capacity in percent and the remaining discharge time did not prove to be entirely reliable in the test. The power bank remained like this for around 30 minutes with 1 percent remaining capacity and 1 minute remaining running time and happily continued to charge connected devices. So there’s more to it than the display suggests.

10,000mAh for travel

With dimensions of 102.5 × 52.5 × 26 mm (H × W × D) and a weight of 212 g, the Anker 533 Power Bank comes in a standard size and can easily disappear into any backpack. With a capacity of 10,000 mAh, it can also be carried in hand luggage when travelling by plane.

Capacity and efficiency in practical tests

Anker states that the Anker 533 Power Bank has a capacity of 10,000 mAh (7.2 V/36 Wh). When charging and discharging a battery, however, losses inevitably occur. The size of them is essential to efficiency. How big they are is critical to efficiency. Bibbuzz has therefore measured.

With a maximum efficiency of 82.2 percent, the Anker 533 Power Bank achieved a good result in the test, but it could be a little higher.

Losses also occur when charging the power bank. In order to charge the 10,000 mAh (36 Wh), only 39.1 Wh is required in the test with a power supply that can permanently provide the maximum possible 30 watts. This means that 8.6 percent more energy was used for charging than the nominal capacity of the batteries.

The total energy loss due to charging and discharging is therefore around 25 percent.

In the test, fully charging the Anker 533 Power Bank took 1.5 hours.

Conclusion

Of course, the model with twice the capacity of 10,000 mAh is not as portable as the Anker Nano Power Bank (test), but it is still the better choice for longer flights. There is nothing to criticize about the workmanship, and the heat development is also pleasantly limited under a continuous load of 30 watts both when charging and discharging, which will also benefit the battery’s durability.

The display is a nice addition, but no longer anything that can set you apart from the competition. Aside from the good performance values, it is also the trust in the Anker brand that the company has built up over the last few years for power banks and chargers that speaks in favour of the Anker 533 Power Bank.

The Anker 533 Power Bank is available in stores from today at a recommended retail price of 49.99 euros. It is available in the colour white, for a few days before it was announced at IFA 2023. She didn’t cause any problems. As expected, it worked smoothly with all devices and not only charged a Pixel 7, iPhone 13 Pro, iPad Air (5th Gen.), Amazon Fire HD 10 and Samsung Galaxy S22 to satisfaction.
