THE SUPERTANK

The 481g heavy SuperTank External Battery measures 119mm in length, 73mm in width and 42mm in thickness.

For size comparison purposes we placed the SuperTank right next to the AC-42K 42000mAh model by Enerpad, the AL420 9000mAh model by Xtorm and the PL3 10400mAh and PL2 6000mAh models by Luxa2.

This small round button placed at the top can be used to check the battery status, start charging and switch between the X-charge and power delivery direction.

At the front of the enclosure we find two USB-A ports (15/18W), two USB-C ports (100/60W) and the digital status screen.

On the end Zendure has printed in detail the electrical specifications of each of the 4 available ports.

As with past reviews we'll be using two ways to test the powerbank at hand, via two USB testers connected with completely empty powerbanks and with several portable devices (Zendure was kind enough this time over to also supply us with two of their braided power cables).
