Sandberg Powerbank PD20W 10000 + Wireless (420-61)

The Sandberg Powerbank PD20W 10000 + Wireless portable battery stands out from its “classmates” with its fabric upholstery on the top panel of the case, which depicts a lightning bolt icon.

Qi wireless charging

The lightning icon stands for support for wireless charging according to the Qi standard, which provides charging power of up to 15 W. All you have to do is place your smartphone on the charging plate, and the process of replenishing the energy reserves in the battery cells of the device will begin automatically. This helps to avoid fiddling with wires and minimizes wear on connectors.

Physical connectors

The model also received two physical charging ports: one full-size USB A and one symmetrical USB type C. Moreover, the latter port is bidirectional - you can charge both external gadgets and the power bank's own battery from it. The USB type C interface provides charging power of up to 20 W (via the Power Delivery protocol). Another microUSB port is used exclusively for charging the Powerbank battery itself.

Real capacity

The power bank's capacity "according to the passport" is exactly 10,000 mAh. This figure is given for a battery voltage of about 3.7 V. When converted to a USB bus voltage of 5 V, the real energy capacity of the model is approximately 6,300 mAh. The device looks stylish and is inexpensive, but sometimes premature failures of the power bank occur - they are not widespread, but occur more often than usual.
