Great product, easy to use and performs as stated.

Have not been able to use the product except to test all components. Look forward to exploring some more of the possibilities when I have time.

Great for off grid and camping

I really enjoy having power on camping trips in the desert.. I can camp longer with solar panels connected to the delta 2 max and xtra battery..

More than just worthy

Great product!!! Since the first test shows 38% input 2 hours before sunset. I’m really happy with the efficiency.

We had a five hour power outage about a week after receiving my battery. It worked just fine. I am very happy with it.

Only solar panels, no power station

I thought the other 1-star review that only received the solar panels was a one-off, but it happened to me too.

Portable and easy to use.

Handy compact solar panel plugs directly into my EcoFlow DELTA 2 Max Portable Power Station. Handy thing to have in a pinch.

Definitely as advertised. Would recommend.

Received a split order on Thursday and Friday. Started testing today (Saturday). Insanely easy set-up. App works well. App includes a very detailed user manual that offers great hints for optimizing the system. Solar panels work well, even producing credible energy output under non-ideal conditions. Does everything I want it to so far, although I'd love some more length to the cables connecting the panels to the battery.
