It uses a high capacity rechargeable battery technology (17 Wh / 3400 mah) in a compact design (2p in picture for scale) and weighs around 100g.

A series of LED indicators shows me the current battery level of the power pack.

The output has an exchangeable tip, which allows me to use the pack for different devices. An idea is to use a USB port splitter for the different devices.

The power pack will be tested with our cameras and devices before we send it up to make sure that it provides enough power for the duration of the flight.
Previous calculations on paper have shown that it should be suitable as we have to take into account the device battery as well.
Heat produced from the power pack will also help maintain a better temperature for the equipment to operate in.
