I had just received my DPUs shipments when this adaptor came in. I wanted to experiment different ways to charge up. Initially used solar then moved on to using my generator. I was able to use my tri-fuel gennie to charge 2 DPUs each with 3 batteries from 53% to 95% in about 3 hrs total. Worked as expected and handled 7200w charging without any issues. If you have DPUs, I'd highly recommend having this adaptor as it gives you another charging option.
Pleased to report that the generator charging adapter works as expected. Two things I wish were better executed- 1st A storage solution for the adapters. I carry the AC charging cord, the EV X-Stream (also works well), and a NEMA L15-30P to 14-50R adapter for connecting my EV charger, not to mention solar panel cords and the like. Some sort of storage solution that could integrate with the unit. 2nd It seems odd to me that there weren't more Trolley's manufactured and available by the time the units were shipping. I still have no way of placing an order. So, my biggest challenge remains pushing the unit through unpaved and unforgiving surfaces. Again, the accessories appear to be as robust in quality as the Delta Pro Ultra itself. I'm pleased.
