Just As Described, Good Buy ✅
It worth it
So far so good its doing fine extended my D2 to 2Kwh
But with no connection cable, how do I link it to the existing unit?
This doubled the capacity of my delta 2 There's nothing like having a backup power. Delta 2 saves space, it's very handy and adds to the home aesthetics.
Sync immediately
The performance
I now double the capacity of my Delta 2: enough power backup... no more problems.
It's nice product
It's a must buy
