I wish the display light would stay on a little longer. But over all I thought it was highly efficient. Worth the buy.

Its been working fine haven't plugged any appliances but real happy with it .The shipping was on time .

A powerhouse that's effortless to use. Coming form an old deep cycle battery system, this baby is a Cadillac.

Really loving it so far! Lots of power, and charges up fast! Display screen easy to read, even in bright sun.

Wanted something to run the fridge during a power outage, that could also go camping with me. This did what I wanted.

I love it- I just wish it could automatically sense the car power and turn off when the engine is off... and it'd be really amazing if it was LiFePo4

Just received my Delta, but haven't had a chance to use it, but it arrived in great shape. Looks like a solid unit. Pleased so fat.

My power went out less than a year after I bought this and it wouldnt even charge via my solar panels.

It is an Amazing Unit as all the wise YouTube influencers said, you can't go wrong with it 'GET ONE'?.. Will Prowse, Hobotech, ect.

Really good service. The cardboard box got pretty beat up, but the battery is well packed with enough padding all way around so it was ok.
