I only purchased one gadget this year: A Lion Energy ME solar generator. At 3000 watt hours and a 4000 watt surge it can run the AC overnight. The 24 volt system can recharge in about 4 hours with a 600 watt solar array or 2 hours plugin. The base unit (1000 watt hours) can run most everything except the AC for a typical 3 day weekend so that’s what I carry in cool weather with no 110 power. The converters are built in: two 110, Two USB, 12 volt anderson, 12 volt cigarette. I also use it as part of my safe room kit. With the CI I can feed the 12v directly in through a cigarette port, bypassing the built in battery, which acts as a backup.
