That 150w limit was down to the fact you had a cheap inverter built into the car taking a paltry 12v into 240v plus many chargers really don’t like inverters like that I had numerous phone chargers that’d trip the inverter out I had. Whereas in this it can charge another car, run aircon & a 55″ TV for 24 hours apparently so I don’t think charging a disability aid would be too much, really good point for us & the scheme vehicle to load could be a game changer.
