Camping and home battery backup

Purchased for use while camping. Maintaining 12volt battery system cooling my igloo cooler while out from site for extended time. Although I never drained below 40% (generator-solar) during day helped boon dock for weekend.

1800w 1 KW Battery.

I found this Ecoflow Delta 3 Classic in Sams Club with an included 10000ma Ecoflow portable charger that has a magnetic pad. It was on sale for $339.00.. Thats 90 dollars off and it was shipped and delivered in 1 day. actually, it was about 12 hours from when I had ordered it ! This is an amazing deal. I checked the Solar charger and plugged it in to charge it fully. I tested the output with a toaster and fluke meter and under load with my trusty Oscilloscope. Perfect... The wife loves the phone charger and I saved 90 dollars. AMAZING ! If I need another one I would buy this again. Did I mention its on sale at Sams Club till July 5 2026.. Get one while you still can. !
