    • Perfect mobile power!
Style: DELTA 3 Ultra+2*400W Solar Panel
Nicely sized, not too heavy and great rolling feature. Great battery life powering a bunch of camping equipment. I even took it to a job site and it lasted days without solar hooked up and with the solar hooked up it would have probably ran indefinitely. Great value for money!

    • Fast recharge at 800 watts
Style: DELTA 3 Ultra+2*400W Solar Panel
Review Image by Amazon Customer Amazon Customer
I use the Delta 3 Ultra for photography trips, camping, and as home backup it’s a beast. Charges super fast with my two 400W panels (I’ve seen 800W on sunny days), runs my fridge, induction cooktop, and gaming setup with no problem. Build quality feels premium, runs cool even under load, and setup was effortless. Perfect combo of portability, power, and reliability EcoFlow nailed it. The wheels make it easy to transport the capacity is just right so that I could use it the next day in time for more sun to recharge everything back up definitely a great off-grid power station and well worth the money if you use it to offset your electricity bill I can run two fridges all day and have enough power to last me through the night and recharge right back up as soon as the sun comes back out. ... show more
