This is the reason why I run a 100amp lithium auxiliary battery, -60amp charger 250amp battery output through a 3500w inverter so I'm never without power, well, for the last 4 years anyway. Would never consider doing this any other way IMOI must say I'm not a fan of running inverters in vehicles as they consume a lot of power when run off the battery.
So, my motto is if I can't power it from the battery, it stays at home. I recently purchased a USB C charger for cordless batteries which works really well. I use it to charge batteries for the cordless drill, blower and eventually, a small chainsaw.
There are options out there that don't require AC power. (now to work put how I'm going to power that coffee machine )
