Solution for mother on a trolly

If you had both the AC charger and the PV side, then it’s absolutely a possibility.

For DIY/camp people, or just, you know, DADS, the slight bit of makeshiftness could even be an advantage. Having the charger as a separate device, which I can also use on an actual car, is a plus. Having the inverter separate, the same way.

Of course not really a solution for mom’s trolley, but could be for some people.

Question though, OT: Am I the only one wondering why humanity is so fascinated by trolley problems?
