@@AdventureRocks I would have gone through there, but I bought mine a couple months ago.

[@charlesb4267]

Earlier this year a friend had bought an old stock 2023 1500 high country and I asked him to see if he could find the 12 volt socket so he looked all over in the cab and was totally stumped ... then read up on it and realized wtf, there is none !. He stated as well that he has a GPS and this or that other device that was geared to plug into the 12v socket. Its not like its an obsolete socket to plug into, there are still items made to this day that are designed around plugging into 12 volts and happens to be that socket system. Without a doubt GM should be bringing that back and also creating a install kit with instructions on how and where to hook up electrically for anyone wanting to install one or more 12 volt "traditional" power sockets into a vehicle that was made without one.

[@AdventureRocks]

Great point

[@georgeharby6818]

I really got zonked. My 2021 had a plug in the bed that you could plug in a extension cord into for electric tools or radio. 10K more for a pickup and no electric outlet😢

[@charlesb4267]

@@georgeharby6818 What year and trim level is the truck you currently have that is missing the 400 watt 120 volt plug in the bed ?, or I assume that is what you were referring to. I wish it was a higher output plug that GM provides like one can get in the Ford ( of course at a fair expense in the case of the Ford option )

[@MattJones1829]

Now we just need a 12V outlet that is hot ALL the time. The 2018 Silverado 1500 I owned had a 12V outlet that was hot all the time. I never had an issue with draining the battery as the only thing I ever plugged into it was a cell phone charger adapter. And if no phone was plugged in, there was no juice going out. I looked at a used 2024 Sierra 1500 today and thought the SLE trim was why there was no 12V outlet. Now I know otherwise! And thank you for the information.

[@tristanpaul3480]

Have the furrion monitor and use the usb c to barrel adapter to power it. Works flawlessly. USB A does not work has it doesn’t have high enough voltage. Note on all those using pigtails you mentioned for furrion cameras. It is not needed for GMC atleast, all you need to do Is manually turn you marker lights to the on position

Good information... thank you... But why don't you want to use the add-on GM camera system with TPMS for your trailer? The added benefits of using the GM TPMS and camera system that integrates into the trucks infotainment system to monitor your trailer is already there. It is what we did for my 2024 ZR2 HD and trailer.

[@GoogleCloudError]

40w USB C PD < 12vdc * 10amp = 120w. GM cost cutting down to the pennies. So if you say want to run a mini fridge, you're SOL.

[@harryniedecken5321]

Usually it takes a 24 volt feed to fully power a PD port, some even need 48 volt.

[@RoadieWingZZ]

Wattage isn’t the issue as it’s a calculated number as the product of voltage and current. If the Furrion camera requires a 12volt input, anything lower than that won’t work. People throw around wattage numbers as if it’s the end all be all answer, but it’s only an indicator of the total capacity of the system/port. If the correct combination of voltage AND current isn’t present, your end device won’t work.

[@AdventureRocks]

Great question! USB with Power Delivery (USB PD) has different versions/specs, but the voltage is variable up to 20V in this case. So identifying the wattage helps determine if the port is powerful enough to supply power to an accessory. For example, the MacBook shown in the video uses an OEM charger with nominal 20V @ 1.75A = 35W. But, it'll take a higher powered charger concerning the watts/amps, as long as the voltage is in range still. And, with the Furrion it only needs a mere 12V @ 500mA = 6W, so that's how it is feasible in this setup. Basically just have to make sure voltage is between 5V and 20V and then wattage under 40W (Volts X Amps = Watts). I was surprised to learn how flexible USB PD is...it's been around for a few years, but becomming more popular to the point GM put it in the truck. And there are newer forms of USB PD that are even more powerful, but not found in the GM trucks, yet.

[@bradleylake6632]

i agree i used that port i hate that it’s gone

[@Podchynok]

I was so dumbfounded, I could not believe the 2024 GMC Sierra did not have 12V port, I even opened the hood and checked if they put it there, no they didn’t. Had to buy 120V to 12V adapter 🤷‍♂️

[@AdventureRocks]

I hear you, I did the same thing initially.

[@robertboyer5498]

That AC adapter is what I went with. Works great.

[@josephdewuhan]

The good thing about the AC is that it only turns on when the engine is running. You will not risk draining the battery when leaving some device plugged in when parked.

[@jerrypierson3450]

Ran into this problem with my 2024 Chevrolet 2500hd, no 12 volt outlet! Plunged my Garmin Trend off road GPS into trucks USB C port, message said if you want full screen brightness, use Gamin 12 volt adapter. I plunged a 120 Volt AC power strip into Chevrolet outlet behind the rear seat, ran in under drivers seat to center of front floor. Bought 120 Volt to 12 Volt dc adapter to plug Garmin Trend in to. The power strip also has 3 USB ports and is powered on when the truck is running, very convenient to have extra outlets on power strip. Very happy that everything is plug and play, as I did not want to mess with the truck wiring and upset its computer.

[@AdventureRocks]

I hear you, great idea on the strip/adapter.

[@ThreeDayRV]

Sadly I have a few "cig" lighter tools, compressor , lights , cooler. I'd have to mount one !

[@BenDere-h6e]

Same here. Gotta rethink everything with my off-road accessories, and I have a '24 AT4 HD.

[@AdventureRocks]

I hear you. Maybe it'll get added back in with a refresh down the road.

[@rickbooks428]

Makes no sense for a high end Sierra HD not to have a 12v port while my 2024 GMC Canyon AT4 has one in the center console.

[@tommarsh5878]

I'm puzzled. I have purchased two different cords to power my dinky little furrion monitor. One was rated to send 8 watts of power through the USB port to a 12volt socket. Nope. The second was a cable with adapter, again USB port. Neither will power the monitor for more than a few seconds, then "no signal" appears on the screen and it goes dark. I recon I should test the power coming out of the USB port. OR hardwire something under the dash. New vehicles can pose annoyances!

[@AdventureRocks]

I hear you. I'm learning that there are different sellers on Amazon selling "same" product and it sounds like some are not up to spec. So a lot of folks are having to return and find another one. I'm really sorry about that. If you find one that is compatible you'll have to report back. I'm hoping to identify a more reliable source/product in the meantime.

[@Intwodeep902]

Off the subject, I updated my phone to iOS 18.1, and having Apple car play issues it will not connect wirelessly

I just got a 110 plug x dual cigarette lighter cause I have the back up camera and garmin gps, does the trick. Can you tell me about your exhaust? Sounds great.

[@roberto3262]

It's the Borla, cat back exhaust system. GM offers it on the accessory website. But you can find it on the Borla site as well. I had one on my 2022 Silverado 2500. It's great. Sounds awesome. I've got a short video on my channel, too. Check it out.

[@AdventureRocks]

[@BustaN3T]

Have a 2024 GMC 2500 HD AT4 and have a Furrion Vision S 7” monitor and it will not power the monitor with the USB-C to barrel connector

[@AdventureRocks]

Sorry, I am discovering there are multiple sellers on Amazon and some versions have the wrong popularity on tip and others are not PD (power delivery) compatible. I'll try to hunt down another more reliable ASIN for this.

[@trollingdirty8910]

Why not use factory aux cameras for inside and behind trailer?

[@AdventureRocks]

Great question! Here is why I selected the OEM camera: kzbin.info/www/bejne/iqfEZZt9ipiXsLM

[@josephdewuhan]

You never mentioned what is the voltage that comes out of that USBc.

[@AdventureRocks]

Great question! The USB-C PD spec has variable voltage, but on this specific port a max wattage of 40 in my impromptu tests. My laptop shown was pulling 15V, so about 2.3 Amps. For 12V devices, should be compatible up to about 3.3A. The challenge can be finding a compatible PD enabled cable as some cables don't deliver what they promise.

[@cliffordmorgan4222]

Curious about the GM camera. 2024 2500 and I have the camera plugs next to the 7pin plug for the trailer.... but the guy at the parts counter couldn't guarantee that it would work.... Said there might be some extra pkg u need for it. I have the camera system on my truck... can't see why it wouldn't work

[@AdventureRocks]

I could be mistaken, but I think if you have the 2 plugs on your bumper then you're all set. You just need the camera system itself. My understanding is, if you don't have the camera provisions, you'll see a 4-pin connect instead of the 2x camera connectors. The camera system has worked flawlessly for me. I do know there is a different model for 23 and prior vs 24 and forward, although they look same.

[@kevinw1287]

I have a ‘16 Silverado that has two USB’s in the center armrest on the bench seat, one in the upper glovebox. In addition, the usual 12 volt cigarette type outlet on the dash along with the 120 volt. With more electronics these days, why are there less power ports? Also, what is the wattage on the USB and USBC in the back seat?

[@AdventureRocks]

I hear you, the fewer ports seems odd. I wonder though if the USB with Power Delivery standard is what has changed things as before one could only send 5V over USB, but with Power Delivery one can do up to 48V and 240W. Granted in GM's application it appears to be the more basic spec, which I believe is up to 20V and potentially up to 40W. I haven't checked the ones on the rear yet.

[@millerm155]

The USB C to 1.35mm plug does not work. The Furrion 7 inch monitor needs 12 volts and the USB C only outputs 5 volts. The USB C to 12 volt socket did work. Apparently the inline box boosts the voltage from 5 to 12 volts.

[@AdventureRocks]

I hear you...I thought USB was always 5V too, but concerning USB-C with Power Delivery (PD for short) the voltage can vary based on the wattage supplied to it according to the official PD protocol. For example, in the video here it is supplying 20V to the MacBook at 2.0amps (40W). With the latest PD 3.1 it can go up to 48V and wattage of up to 240W (USB PD 3.1)...again with the proper power supply feeding it. GM seems to have a previous PD standard in use on my truck, thus the lower wattage. I think the challenge is, while PD is an official protocol, not all cables and outlets advertised as being PD compatible comply with the protocol 100% so there can be compatibility issues. Here's a link with more info: www.usb.org/usb-charger-pd

[@Ritosanz1289]

How is your back up and front camera at night ?

[@AdventureRocks]

Pretty decent. If you're asking about the built-in surround view on truck (front/back/sides) between the reverse lights (I upgraded mine) and headlights there's plenty of light to enhance image. Otherwise, fi asking about the GM trailer camera on my RV...I haven't used it a lot at night as for me it's more for getting into my campsite or storage backing-up solo. Of course no infrared night vision like the Furrion, so gotta have some light to help but I'm happy with it.

[@kirkdunn1379]

have a 23 silverado 2500 HD and have 2 of these 12v ports....1 in the front and 1 in the back seat, along with USB c and house outlets.....have no idea why anyone would remove them from a truck.....bean counters saving $5 a truck seems ridiculous but you never know I think even the upfitter switches should be standard in HD trucks....they are working, camping, hauling, etc......its a work truck first and foremost then to what degree of comfort is the trim levels

[@AdventureRocks]

Great points. I also wonder if the GM decision makers got some bad data regarding owner surveys and how many owners actually use the 10A 12V outlet...maybe the survey data showed such a low percentage that it caused them to decide in favor of axing it. Or, it could be one of those things that some of us may seldom use, but we consider it a necessity regardless.

So is the USB-C port in the rear another 40 watts?

[@AdventureRocks]

Thank you for the comment, and thanks for your patience. I was able to test the rear port out and I got 27W and 30W back to back, which is slightly less than the front port. It could be a fluke, or could be that the rear is slightly less powerful. Main thing though, is that the rear also supports USB-C PD (power delivery), so that's a plus.

[@Neur0bit]

Great video. However, the MacBook’s smallest charger is 65W, not 35W.

[@AdventureRocks]

Thank you! And, great question! Surprisingly on the new M2 and M3 MacBook Air, 35W is standard equipment. But, you can upgrade to a 70W if desired. I can imagine 35W sounds low, but the Apple silicone chips are very efficient, so less wattage required. I was surprised to see the truck feeding 40W to it though.

I have been a die hard GM truck guy for over 35 years. I couldn't believe it when I couldn't find a 12 volt accessory outlet in my new 24 HD. WTH GM? Anyone that uses a truck as a "truck" and tows knows you will need at least a 5 Amp 12 volt accessory outlet. This, among other discoveries, is making me rethink my loyalty to GM.

[@AdventureRocks]

I hear you. Maybe they'll bring the 12V back with a refresh.

[@kempie9901]

Is that 40 watts at 5, 9, 12, or 19 volts? Either way to be honest, 40 watts is terrible. Thats like 3.3 amps. So 1/6th of that the old 12v outlets were capable of.

[@AdventureRocks]

Great question. As best I can tell the 40W is max output regardless of voltage. With my MacBook in the video it was 20V = so 2A, but you're correct at 12V it'll be 3.3amps. The USB PD spec is kinda neat the way it can function at different voltages. Maybe it doesn't completely make up for the fact the 10A 12V outlet is missing, but it at least helps cover a lot of the devices we might use with a USB PD cable.

[@TheShanman69]
