In addition, three USB-A sockets offer 5V for a maximum power of 18W.
The other DC outputs are a 5521 and a carport, supplying the same regulated 13.6V supply at 10A.
Two 120V AC outputs supply 400W under regular operation and can boost to 800W for short durations.

The unit’s versatility is on full display thanks to the Bluetooth low-energy connection.
It is an excellent feature since the rig rarely loses connection with a paired smartphone.
