EcoFlow Delta pro extra battery

I have the Delta pro and one extra battery at the moment and I'm looking to purchase a second battery. I like everything about the units except what another reviewer said, the cable to hook the extra battery up it's so short the extra batteries have to be on the two sides of the Delta pro power station. I have them in a small laundry room on a shelf and I wanted to put the extra battery on the shelf but since the cable is only 3.2 ft or meter long I can only put one battery on the shelf above the Delta pro power station. So if I want to add another battery it will have to be on the floor right next to the power station for the cable to reach. Unfortunately then my dryer door will not open more than a third. They said I could buy the 16-ft cable with the smart battery adapter which is way too long. Can't we just get a seven or eight foot cable I hear a lot of people with the same issue. I'm sure 16 ft cable plus smart battery adapter isn't cheap either. And then there's 16 feet of cable to have hanging around. That's the only reason I took one star off everything else is great but I'm in a bind hooking up the extra battery with one option, buy 16 ft cable with extra battery adapter. I called EcoFlow they have no intention of making a 8-ft cable or just one that would actually work. The ease of use is very easy but I took a star off because I had to take one off because no one thought of making a cable long enough to stack the batteries. And it's not some cord you just go in the store and buy one.

Size and Safety

Have 2 Delta Pro's and 3 Extra batteries. You can't beat their price, warranty and customer service, for a self contained unit that's safe to use!

Love the Delta Pro

We have been using 2 Delta Pro and had an extra battery for each. As we Solar powered those, we realized we needed an additional battery. We are thrilled with performance and ease of use. We use them continuously and have reduced our power bill to 1/3 of what it was a year ago.

Extra Battery Needs Longer Connecting Cable

If the cable connecting to the Delta Pro had been longer I would have given this EB a five star. But I had planned on putting the EB on the shelf below the DP and that was almost impossible. The only way I could do it was to effectively put the DP on top of the EB with a wire shelf squeezed in between them.
