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. !

Best deal for a 1kw 1800w Power station

This Ecoflow Delta 3 Classic is an amazing deal. its made for Basic back up. It arrived in just under 12 hours from the time I ordered it. Someone said this deal was not real. They are wrong. My Delta 3 Classic arrived perfect with the included Ecoflow power bank. 1800 W means 15 amps at the outlet. 1 kw is good for a short term power outage. if you paired this power station with a small inverter generator you could have almost unlimited energy and no noise at night. You should get one while you can..

Camping Lovers Must-have

I bought this for early camping (our campgrounds don't fully open until after spring break). It worked great! I ran a small heater in our camper and charged all of our electronics all weekend without any issues. I've even charged phones and my husband's diabetic pump during power outages since. It's came in handy for multiple occasions.

Magnetic Charging Power Bank is Missing.

I received the package from FedEx yesterday. EcoFlow Delta 3 Classice works as I expected and I would like to give 5 stars. But Magnetic Charging Power Bank is missing (not included in package as listed). I did contact Sam's customer service and they said will investigate and get back with me in 48 hours. I will update later.

Missing the Powerbank

Do Not Buy! Received the Ecoflow Delta 3 but not the powerbank. With so many bad reviews reporting the same issue over several months, Sam's Club clearly doesn't care about it's customers enough to resolve this.

Maybe Next Time

This is really a Sam's Club review, not an Ecoflow product review: Excited to see these on Sam's Club online. Power outages are a way of life here. Affordable, clean option for basics (fan, lamp, fridge) during outages. Local Sam's listed plenty in stock (8): store was closed for the day; paid online (purchase hit my bank immediately); pick up time 10AM next day. Thought I was good to go. Got up drove the 30 minutes to pick up my Delta 3, yay! Local club didn't pull my order and sold out before 10 AM! So close, yet so far away… Such is life! I hope there's another sale. Can't afford otherwise.
