Silicon Power QS28 20000mAh Power Bank Review

Others/Miscelleneous by stefan @ 2022-01-02

The QS28 20000mAh power bank from Silicon Power is quite helpful when going in longer trips in order to handle multiple charges for your smartphone, quite a bit of recording hours with the action camera and you can also top up multiple devices at the same time (maximum of three). In our tests, the charging indicator has dropped to just about 73% when charging our trusty Galaxy S21 from zero to full, while keeping the smartphone on so lots of power left!
