Basic RV gear

Just what it's meant to do. It changes a 50-amp circuit to a 30-amp one, like in the picture. It works really well. It's totally worth the money and a good thing to have around when you need it.

Efficient and affordable choice

I bought this 30 amp to 50 amp adapter for our big motorhome, and it was a breeze to use thanks to the easy-grip handles. It cost way less than what the RV dealerships charge.

Works as decribed, easy to see

I'm using this gadget between my Champion generator and Power Watchdog for my 50 amp fifth wheel. We don't hook it up at every spot, but the bright yellow color makes it easy to spot down in the electrical box.

Perfect 30 to 50 conversion

It's reassuring to know I can switch from 30 amp to 50 amp when I need more power. It works just like it says it will, with high quality materials that move electricity really fast.

Built to last and works great

This "dog bone" adapter lets you connect a 50 amp cable to a 30 amp outlet. You won't power all your 50 amp gadgets, but it's perfect for the basics. It does what it's supposed to, feels solid, looks well-crafted, and seems like it'll hold up for ages. I've been using it for half a year without any issues.

Reliable quality

This sturdy unit is well-built, feels like it could last for years. I've got a motorhome and I keep it plugged in most of the time at home. It's also a reliable tool in my daily work, always performing as expected.

Needed a replacement to my old one

The NEMA TT30P to 14-50R has great grips on both the plugs and the socket, and it comes with a strong gauge wire that's clearly marked with the right info on how to use it. It uses 10-gauge wire, which is perfect for 30 amps. Just to let you know, this adapter gives you 0 volts between the phases (X to Y), and 120 volts from each phase to the neutral. With this setup, going from a 3-prong to a 4-prong won't give you 240 volts at the 14-50 socket.

Useful to keep nearby.

We keep this "dog bone" in our RV gear for when we need to connect to a 50 amp electric outlet. It's good to have around just in case.

The adapter meets expectations

I snagged this at a great price after a mix-up with another company that kept sending the wrong item. I won't go camping without it now! I bought it as a gift too, and my friends absolutely loved it.

Durable and long-lasting

It works really well for what I paid. Not every campground has the 50 Amp service, but this adapter lets me plug my 50amp cord into a 30amp power source, just like the product title promises.

Gary
Ideal for home RV garage

Great value for the cash. It's a must-have for any RV owner. The angled design eases the strain on your rig. It's high quality at a sweet price. Haven't had to test it out yet, but it's a great safety net when a 50amp spot isn't around.

Performs as promised, so far so good

It does just what it's supposed to. The grab handles make connecting and disconnecting a breeze compared to others. I used it to replace my old one, and it's been great.

Well made for the price

If your camper runs on 50 amp power and you're hitting the road, this should be in your toolbox. I've had to use it already, and without it, we'd have been stuck without electricity for the night.

E
Edward
Great. Worked Just Right.

I finally got to test this out when the 50amp breaker tripped at a campsite. I switched to 30amp with this adapter, and the cord stayed cool. Even with two air handlers going on 30amp, the breaker didn't trip again. It's a quality product.

Melted after two uses...

The hot wire totally fried the casing. I ran the 50amp cord from my fifth wheel to a voltage booster, then from the booster to this "dog-bone" adapter, and finally into the pedestal.

Great and simple to use. Nicely Made!

This power adapter lets you lower the plug voltage for your RV, so you can keep the fridge plugged in even when the RV's not in use, like during storage. It's really user-friendly and well thought out!

Perfect for home RV garage with 30 amp power

This adapter is perfect for connecting my trailer to my home's 30 amp electrical outlet. It's good quality, and I hope it'll last a long time. It works just as well in my RV garage with the 30 amp service.

Durable dog bone adapter.

Our camper runs on 50 amps, but since it only has one AC unit, we just need to connect to a 30 Amp source. That's what this adapter is for. It works great, and we got a new one because the old one got partially melted at a campground during our trips. Worth the buy.

Sturdy and high quality build, recommend

It does exactly what it's supposed to. Fits securely and it is well made. I don't use it all the time, but it's a must-have when I do. No issues so far.

Fred Caprotta
Look extremely sturdy and great quality.

We needed this adpater to plug in our fifth wheel for camping and it worked out awesomely! A great buy to have on hand for converting power from 50 to 30 amp. It looks like a solid product for the job.

Quality work, fast shipping

This product arrived just as we expected and has become an essential adapter for our camping trips, we've used it every weekend this summer! It's exactly what I was hoping for: solidly built and super easy to use.

Great for Switching from 50 AMP Camper to 30 AMP Socket.

I was looking for a way to power the essentials of my camper while we're getting it ready for a trip. My camper runs on 50AMP. I use my camper cord to connect to this adapter, then plug it into a 30AMP converter, and finally into a regular 110V socket in my garage. It works great for charging the batteries, turning on the lights, pumping water, cooling the fridge, and powering outlets. But I wouldn't try to run the air conditioner with it.
