Parkworld 885545 Combiner, RV Splitter V Adapter Cord 5-15P & TT-30P Male to 14-50R Female

It works! Used for my 50amp trailer and powers both ac’s and everything I need to power in my trailer. As description say it will not work with gfi outlets so take that into consideration. Very simple to connect up plug and play

Shorted on 1st use, killed my inverter. Only provided 83 volts to some plugs. Seemed to be sturdy, I may have gotten a bad one, but it was a expensive experience.

This works very well if you use it correctly. I used an existing dedicated 20 Amp receptacle in my garage. I removed the gfci receptacle and made the box into a junction box. I then ran 12/2 wire from the junction box outside to an In-Use water resistant covered 20 amp receptacle, right next to the existing 30 amp receptacle. Both male ends of this adapter were able to plug into a covered water resistant receptacle. I had previously turned off everything in the rv. I connected the plug end of the adapter to the male plug end of the rv. I then turned on all things in the rv. It works perfectly. One hot 30 amp blade of the adaptor runs the living area and its AC. one 20 amp blade runs the bedroom and its AC.

Haven't been able to get this to work. I think maybe it doesn't work if the 20A outlet is GFCI which most of the campground power posts seem to have.

Instantly popped the 20 amp breaker when I try to plug it in

I used 2 110 volt outlets on my RV to get 220 volts.

Made good but didn't do what I wanted it for

The prongs must be made too thin because it doesn’t stay plugged in. Everything else that I plug into the same receptacles are nice and tight.

I sent back this idem wich was functional on the 30A channel only...
