Is that running on 12V? That’s amazing that you can draw >100A through that cigarette lighter port without a fuse blowing or something overheating. The wire to the plug alone looks like it would melt at 100A.
A second alternator and battery was the mainstay for overlanding in lieu of intermittent solar PV. Honestly the 48V system (as opposed to 12V idle) could recharge the batteries within an hour of driving. Even several hybrid ICE and PHEVs have 1500W 120V plugs or in the case of the hybrid F-150 a 7.2kW pro power onboard generator output. The portable battery/inverter that I am using has a 1800W continuous and 2700W peak output. 28lbs for LFP is reasonable for ~0.8kWh usable.It looks like that is a battery pack inverter that can charge off 12V in a car. The pack can handle the higher load and it will be charging from the car but not keeping up if the load is sustained.
I could be wrong, but it's a great solution to use the power stored in an EV.
I looked into the AC200P, but it is a beast at 60.6lbs!I’ve been using a Bluetti 2kWh unit for about 2 years now, first in our gas car and more recently our Tesla. We take a fridge/freezer unit on roads trips, powering it from the Bluetti and powering that off the 13v outlet in the trunk. Works great. Bulky though so we keep it in the sub trunk.
