Looks like no. I wish. Just tried it. It seems to be only for accessories. It does work on the solar panels. If you find one for the actual power station let me know!

I've been eyeing their refurb's listed on ebay. Theres a 20% off coupon on ebay currently and it really makes them attractive to pickup at those prices.

I see that it lists compatibility with the Delta 2 but not the Delta 2 Max. Why wouldn't it work with the Max? My understanding is it's basically the same unit as the Delta 2 with more capacity and extra ports...

Finally these are getting to prices where they somewhat should be.

~$300/kWh.... they're finally coming down, this is the best $/kWh ratio I've seen for a brand like EcoFlow or Anker.

May it continue down to $250/kWh and below!

Thank you for the answer.

I was looking at the pictures and this doesn't seem to have the cable compartment like the older ones had. Can you confirm this?

no can not user lower rated output (power) extra battery with higher power main unit.

Delta 2 Max main unit has higher output capability, and lower output EB's aren't designed to be used for that higher output. The compatibility list in this instance is correct.

no problem.. correct, D3 EB does not have a compartment like the previous generation D2 EB. But the cable IS still included (and the nicer (subjective) newer right angle EB connector) with D3 EB

Note that if you have the Delta 3 1500, the right angle and shorter cable doesn't allow for you to stack the battery on top. Ended up using the cable that came with the Delta 2 extra battery and then this newer one with Delta 2 Max.

I thought I got a good deal at $400 a couple weeks ago. This is a killer deal. And a great battery. I like the delta 3 plus because of the ability to have two 500w solar connections yet still be very portable.
