I appreciate the suggestions and am pretty versed on what's available in the aftermarket. I was just wondering if anybody was knowledgeable about what's typically installed these days.


We'd really need to see the exact style/brand of USB port to know (or research) what the spec is.

I've seen about 5 different style of USB ports used across all the brands of RVs I've looked at.

Outdoors RV uses higher output USB ports. I upgraded my charge panel with more stuff as shown in this video

My first truck camper pre-dated the era of USB charge ports in RVs, so I added a Blue Sea Systems panel as shown in this project

OP here.

I wasn't looking for a standard, just tell me what's currently installed.

I've installed plenty of USB ports among many other things in RVs, so that's no big deal.


I think the answer is no one knows...not even the manufacturer...buy the tester if you must know.


^^THIS^^

Or when you get the new RV plug your high current demand device in to charge. You will figure it out quickly if the device takes a long, long time to charge..

If charge time is comparable to your charger the device came with then the ports have sufficient power for you device to charge at normal speed.

Pretty much all devices that use USB 5V to charge from have the capability to detect and auto negotiate the charging source capability. If it is not able to draw enough power it drops into a lower rate charge mode.

Does not hurt the device, just means you might be waiting several hrs instead of 15 minutes to recharge.

If you find it is taking a lot longer time to charge, then consider adding your own aftermarket higher current charging ports.

In other words, don't let this concern make the choice of RVs for you.

Just remember, rapid charging is convenient but very hard on batteries and will greatly reduce battery life.

Granted, however for most devices charged via USB 5V the device it's self is already "obsolete" the day you bought it and it's useful life is not determined by the battery life but the software version and when the manufacturer decides to stop supporting the device via updates.

Fair chance that your battery in the device will well outlast the device usefulness hardware and software wise and most folks now days must have the latest and greatest device which means trading them in as soon as the contract allows for another free (or greatly discounted) device and signs them up for another contract period (typically a 2 yr lock in)so the phone company is guaranteed to have that customers money and soul for the entire length of contract..

Many new(ish) devices require the higher powered, 2.1-amp USB plugs. On the flip side, most of the plugs I've seen in RVs I believe are under an amp. Anybody knowledgeable on this subject? Is the RV industry keeping up with technology?

Well, it looks like nobody knows (including me), but if you need more USB outlet power look to updating your AC outlets.

The only problem with those is you have to have 120v power or you have no 5v power. For people who boondock, it is not an answer.

OP didn't mention anything about boondocking.

OP may not have mentioned boondocking but if one has a 5V USB charger, one would like it to work anytime and anywhere.. 120V outlets with USB chargers would be a real letdown if you happen to be anywhere there is no commercial power and you have to break out a gen to charge your 5V device.. Think of like this, pull over at a rest stop cor a couple hr nap and you want to charge a device.. 120V outlet with USB charger isn't going to work in this case..

120V outlets with USB chargers would be sort of nice in your sticks and bricks provided you had them everywhere in the home..

To me, they are an expensive built in option and when the charger dies or is no longer sufficient for the newer devices, you must replace the entire outlet..

Dedicated USB chargers which pull directly from 12V battery would seem to be a much better way to go in a RV..

At home, I bought several USB chargers which have 12 USB plugins which have up to 3.5A on three ports.. So far, have only needed 4 of those ports at one time.

In a RV, just use plug in 12V cig lighter styles, have one that has four charging ports which handles all of our stuff. May not look as pretty as a built in, but it is portable and can be used in any 12V power port.

OP here. We boondock as often as we plug in. I have built in higher amp USB and/or cigarette lighter plugs throughout my current trailer to cover any needs that may arise. It looks like I'll probably be doing that in our next RV as well. It's kind of fun to modify these rigs to suit needs and tastes.
