The Mobile Terminal is a small, convenient handset which is used to adjust and update all update-capable PowerBox products. A powerful 32-bit processor with Wifi and Bluetooth, in conjunction with a touch-screen which is clearly legible in sunlight, make the unit similar to a smartphone in use. PowerBox devices can be updated directly using the lead supplied in the set, or using the optional BlueCom™ Adapter . All the usual settings are available for many products which were formerly set up using PC-Terminal and the USB Interface Adapter.

The unit can draw power from a separate battery, or from a PowerBox. The Mobile Terminal always has the current software versions available via Wifi. These are automatically downloaded in the background, and stored on the integral SD card.
