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.

Outstanding Performance

I've had my unit for about 6 months. I installed it in my work shop to power the shop and the greenhouse next to the shop. It is hooked to the grid for charging. It also has an extra battery, and has 300 watts solar also. It provides power to everything I need to power. I really love it.

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. !
