The Silicon Power QP75 Power Bank has an elegant design, with an all-matte rubber coating applied on both sides of the casing. The edges of the power bank have a matte texture but are not covered by the rubber coating. This creates a good contrast between the two shades of black present on both textures.
The QP75 Power Bank has a weight of around 220g and the dimensions: 147.6mm x 74.4mm x 15.5mm.
The front side of the QP75 is simple, with only the straight lines carved into the rubber coating present. However, the only LEDs of the product are installed on the lower side. These four LEDs are the charge status indicators, and each LED indicates around 25% of the total charge.
The back side of the power bank is just as simple as the front. On the lower part, instead of the status LEDs there is a large round button. When pressed, this button will turn on the charge indicators for a brief period.
The main output and input ports of the QP75 are installed on the top and bottom edges of the casing. These are marked with bright orange, and are the only static ports of the power bank. In addition to being an output port, the USB Type-C port doubles as the only input port of the power bank.
The secondary output ports of this power bank, a single USB Type-C and a Micro-USB port are hidden within the structure of the edges of the casing. These two ports are not only detachable and mobile, but are permanently attached to the power bank. This means that even if the charging cables are missing, the QP75 can still charge up to two devices.
