Good

The Delta Max had charged up effortlessly with the extra battery hooked up to it. I haven't had a reason to try it out yet. I want to try it out on my refrigerator first. Maybe this coming weekend.

Gamer Friendly

So I purchased the Delta 2 and the Delta 2 extendable battery I have these hooked up to my UPS which powers my gaming desktop my monitors and my gaming laptop. I have it set up so that the grid power flows through the Delta 2 and into my UPS which then flows directly to the computers and the monitors I have it set at 50% state of charge and it seems that the pass-through charging works perfectly The input power matches the output power watt for watt. With this being said my current idol usage is 550 watts that is pass through from the grid. It's working perfectly. my cons: i wish the application had more information on the second battery, more control of the charging parameters, i am also not keen on only being able to expand this system one time for the price you pay for a complete system i feel like you should be able to stack 2 too 3 of them together in my opinion.

Delta Max Solar Generator

Though I haven’t used this as a solar generator yet it has become my go to for power in my remote cabin in the Adirondack Mountains. Just the convenience of being able to power a few lights, tv, and sat modem without running a generator is awesome! I can recharge in about two hours off the generator that I used to run all day to power up my camp. I eventually will add some solar panels at some point but right now it’s great to not to have to run a generator all day. I had looked into buying panels, inverter, and batteries but found this as an very viable option.

Works correctly

Works as advertised. Have cycled it and done firmware update and all well. I wish the cable took up less room.

The real review

It's nice but the cost... the quality is the same as the generator. Easy to hook up. Charges fast from electrical socket.

Clearer description

Stating that the cable for connecting to the delta max came with the battery would have helped. I ended up purchasing one

When you need more power, you add more power!

I paired this with my Delta 2 and it worked well! I run Starlink and my fridge off my Delta 2 and I had to turn off Starlink before going to bed to make sure it has enough juice to power the fridge the whole night, which is not really a problem. However, when I want to run Starlink, EcoFlow Wave, and fridge off Delta 2, I realized I need more power. The Extra Battery, even with different battery from Delta 2, worked flawlessly. I now have combined 3kw of power for me to use while camping!
