What it is

A 150 kWh power station on wheels

The Power Wallet (WP150) is a high-capacity mobile power solution mounted on its own electric trolley, so it can be driven from place to place rather than fixed to one site. Inside is a 150 kWh LiFePO₄ battery with a smart BMS, an integrated EV charger with a Type 2 output, and 230 V AC plugs for tools, lights and equipment. A 7-inch touchscreen runs it, and operation is fully automatic. It's clean, silent and emission-free — power and EV charging that simply arrive wherever you need them.
