EF ECOFLOW Double Voltage Hub for DELTA Pro, Portable, Battery Powered, 7200W

I purchased this to allow me to use an EV charger at the full 30 Amps / 7200 watts that the double voltage hub is capable of.Unfortunately, after trying it on two different EV chargers, I get an error message that there is no ground.I have the EcoFlow grounding adapter, which works if I try to plug in the EV charger on just one DeltaPro; however, even out of the 30-amp outlet, I can only get about 15-16 amps.With or without the EcoFlow grounding adapter on the Double Voltage hub, I get a grounding error and cannot charge the EV at 220v. Therefore, I plan to return this product.UPDATE: I found out that the problem was the adapter I was using to take the plug from a 30 amp to a 50 amp.My EV charger plugs into a 6-50R outlet. After I purchased this conversion plug:https://www.amazon.com/gp/product/B07GSJNRHR/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1Everything worked great! Very happy now with this purchase

The quality is so good all of echo flow’s products. I wish I could afford to get one more xtra battery and or the generator!! Soon!!

I purchaed 2 EcoFlow Delta units and needed the Double Voltage Hub to feed the transfer switch.The double voltage hub worked and has been in use to provide backup power during a power outage.I have tested this running the house in an off grid mode. The dual coltage hub will not balance loads, it is not designed to do that. The dual voltage hub is not designed to charge the delta pro's that is the reason for no rating under that heading. If you want a backup whole house source this is a very good combination, thoroughly recommended.

very glad Eco Flow has created a way to generate 240V home battery backup affordable!

Haven't had a chance to use it yet, but sturdy construction.

Quality product

Was shipped to me with little to no protection for the device and was broken when I received it. EcoFlow did replace it after I sent a video where you could hear noises of something rattling around inside.Hub only good in an emergency as the Delta Pro cannot charge from AC power while the Hub is active. So you cannot use this to leverage the batteries in your home setup.

If I had to do it over again I would not buy this product. You need 12 batteries for each box. I bought 2 so I need 24 batteries. I didn't think about how that would impact using this product but it's a royal pain. I decided to try the product out and it's built like a cheap toy, but appears to be okay. The light itself didn't do it for me. If you set it down on something the light is harsh to my eyes yet doesn't really light up that much. I haven't tried all four together in the same area, but I will assume it would be nice, but the 12 batteries to charge made this product less desirable for me. I'd prefer something that could be charged and of course that's my own fault for not considering that as the only option.
