NEMA 10-30 Level 1/2 Electric Vehicle (EV) Charger, 10-24A, 110-240V, 10-30 Dryer Outlet Plug, NEMA 5-15 Adapter, 25ft UL Listed Cable, J1772 EVSE for All EVs/PHEVs, Portable Home EV Charging Stations

We’re saving up to get our panel upgraded and some other electric projects, but in the mean time, would getting something like this and using it in a NEMA 10-30 on the 10A or 12A setting be reasonably safer in the meantime? I’m using a level 1 right now and it’s only enough to recharge half my daily commute so I’d only need to use the level 2 charger 2 maybe 3 times a week.
