Hey there. Quick question, I am traveling to visit a friend and will be plugging in at their house. Can I use a 30 to 15 amp to plug into their house? Am I only limited to certain things e.g. fridge only no AC? I really was hoping to get AC, but don’t want to cause any issues. Advice needed. This is what I am looking at. 30 Amp Male to 15 Amp Female Dogbone Adapter RV Electrical Converter Cord Cable https://www.amazon.com/dp/B07SSZ8DVZ/ref=cm_sw_r_cp_api_i_4ZZ5EbKPW1PTB I have a travel trailer. What do you suggest if you were in my situation and needed AC. Thanks!

Your link does not work but NO. You need a 15/20 amp male and a 30 amp female. It"s called a 30/20 dog bone. If your rig trips the the friends GFI circuit you will need to turn OFF you GFI circuit in your rig. A/C may or may not work.FYI, AC = 120 volt electric. A/C = Air Conditioning.;)

Get a 15/20 amp male to 30 amp female dog bone (adapter) or puck. Avoid using an extension cord. If you have to use an extension cord, make it as short as possible and either 12AWG or 10 AWG.When running the AC, turn off the electric water heater. After running the AC for awhile, feel the dog bone or puck connections. It may get warm, but make sure it's not getting too hot.

So do you have it backwards?You might be able to run a small A/C on a 15A plug but typically not because you have other loads like the refer. The typical household circuit has multiple 15A plugs on a single 20A CB. Which means there may be other loads in the house on that circuit.The typical household type plug found at campgrounds is a dedicated 20A rated plug. My garage has a dedicated 20A plug - ie a single 20A rated plug on a 20A CB.And the situation is more marginal if you need to uses an extension cord due to the additional voltage drop on the cord.

you can step down to 15A. you can use whatever you want as long as you dont draw more than 15 amps at a time. my trailer lives a lot of the year plugged in like this at home. I can run my fridge, phone chargers and AC, not much else. If i need an appliance or some other power draw i switch off the ac while im useing it then turn the ac back on when im done.

may be a quick question but not necessarily a quick answer. It depends upon 1) what else may be on the circuit in your friends house,2) if it is a 15 amp or 20 amp breaker3) how long of an extension cord you may have to use.4) how good you are about managing the electrical loads.5) whether your battery charger kicks on at the same time as your fridge or your AC, etc.we plugged into a friends house and everything seemed fine for a while and then his breaker would trip every time his freezer in his basement kicked on. turned out it was on the same circuit.

If you have a 13,500 btu it might run on 20a circuit but I doubt a 15 would. Air conditioners are expensive, I personally would chance running it with borderline amperage.
X2 Plus other loads. And you can quickly get into a low voltage situation which does not favor A/Cs.

Recommend you use a digital voltmeter to check the actual voltage.

BTW My house has a 270' circuit (not optimal wiring) First time I plugged in my saw it wouldn't cut a 2x4.

This held true for us while camping at my bro-in-law's house, too. You pretty much get to run "one big thing or one heat producer" at a time. The heat producers like coffee pot or hair dryer use a lot of power, too. And we used a GOOD extension cord - many-stranded, 12 ga w/ground.

for what its worth this is with the 30 amp cord all the way to the wall and the adaptor at the outlet.

This is the adapter that you would need. :)

One HUGE thing not mentioned above? The draw your converter has on that circuit. Your onboard converter draws almost 10 amps when it's charging your batteries. That leaves you with very little power for everything else.

OP I looked at your link this AM. The default title shows 30A M to 15A F and it shows 6 adapters. If you CLICK on one of the adapter then the title changes for that adapter, be sure to do this as otherwise you'll order the default title adapter.

may be a quick question but not necessarily a quick answer. It depends upon
1) what else may be on the circuit in your friends house,
2) if it is a 15 amp or 20 amp breaker
3) how long of an extension cord you may have to use.
4) how good you are about managing the electrical loads.
5) whether your battery charger kicks on at the same time as your fridge or your AC, etc.
