I bought a 2023 HD Silverado and I try connecting a vacuum to the bed, so I can vacuum the interior. The inside outlet or bed outlet wouldn't power up the vacuum. I know there is button on the console that I have to turn on for the outlet to work. Do you know why would this be happening?

I did the exact same hung when I got my truck. I think the outlets are only 400w. Most vacuums require more power than that.

The 400W is quite impressive but only provides like 3.3 or 3.4amps just using quick mental math.  Just divide wattage output by 120 and that will give you your amperage rating.  The truck also has to be running I believe for it to turn on the 120V outlets (at least mine has to be) with a press of the button.  Perhaps they might work in accessory mode, I've never tried that.  But I am kind of surprised it didn't at least try to run your vacuum.  It will run power tools easily.

Jettech1,

 

I was surprised to since 400w should be able to power up a vacuum. I was more surprise when the inside outlet did the same thing. I know the truck has to be on. I have not tried in accessory mode, but I will try that tomorrow.

Both outlets are rated at 400W so it shouldn't matter which one you use.  I only mentioned the accessory setting in the event you had the key off.  Look at your vacuum model then do a google search on power requirements for it.  Or it may have a sticker on it telling you.  That might help you in determining if it is within the 3.5 amps we will say the truck puts out.

You are probably right.  We have a Dyson electric vacuum that we use.  Best damn invention on earth if you don't own one. Got a killer 1/2 price off black friday deal.  Even with it half off it was kind of pricey, but holy crap....That thing is amazing!!

3.4 amps is nothing. My saw is 13a and sawzall is like 9amps. It will probably only run like a radio or other items not power hungry. 

Very true statement.  I ran a cord from my dash outlet to the backseat area under the 2 HVAC outlets to a 5 outlet strip cord with 2 USB's in it so that anyone in the backseat could use it to charge their phones or I can charge up the batteries for all of our Bauer 20V electric accessories that we have.  That's probably the best use for what little amps the outlets actually put out.

If you look real close under the vents you will see it.  I used 2 zip ties to secure it to the all weather mat.  Not perfect but it works great.

these outlets kill me,  pretty much only good to power a cell phone or kids tv.  The companies need to step the inverters up to at least hold 10amps,  most are only 3-4amps which doesnt do a whole lot

More amps more dead batteries. They weren't made to power hungry things. Simple.

true, but theres no reason they couldnt either disable the outlet if the truck is off, or step it down when the truck is off to a lower amperage.

I figure they were thinking laptops, better than no outlet.

      Lets Talk Z60 Suspension

      By ryan35205 · Posted

      Did the KYBs keep it the same height in the front? I was concerned that pre-assembled assembly would raise it up an inch to standard non-z60 height.. I guess which it would make the rake 1 inch instead of 2 inches.

      Thank you for keeping the train on the tracks and for a thoughtful engagement. I enjoyed the reflection on a previous stance to refine and improve your position. I like that inquisitive flexibility about you Atlas.    No the process isn't sterile. Hundreds, perhaps thousands of miles of piping, vessels, pumps. Chevron, the people I worked for, were keenly aware that there is a market for what is known as their "ISOCLEAN" line of lubricants. These are lubricants that are the same as those sold bulk that are further processed by filtration to a level your particular application demands. They will filter and package and provide lab documentation as required. Do not kid yourself. Every gallon of oil that goes into a Chevron Turbine, reciprocating compressor, generator is prefiltered and tested before being charged. Lest wise it was when I was there in the plants I worked in.    There are requirements set by manufactures for the cleanliness of the oils used in their equipment. OTR such as CUMMINS has standards shared with customers on this. Commercial interest selling to Ma and Pa do, but don't share that information. Not even upon request but internally, they do exist.    The GM study sited, (Graph from Machinery Lubrication in previous post) only shows "relative" importance.  I find that fascinating. By constructing the graph like this they admit there are dozens of factors in engine life and via scientific method determined the effect of 'relative cleanliness' on engine life not in miles but in 'FACTORS'. This allows a certain amount of reverse engineering does it not?   They even provided some touchstones. Beta 75 as a reference point. Wonderful stuff!!   Smaller blenders CAN and some DO take the time and effort to do better than a refinery or large bulk blender, like Warren Oil, in improving the "in the can" cleanliness. No I don't have a list but testing could generate that information.    Again, but one of several levers we can pull to improve engine life. The simplest is keeping a clean work station while doing your own oil changes.

      Thank you. I'll give it a try

      I just spent the last 45K miles doing samples every oil change over more than a full year to get the data for seasons and break-in to broke in.    I found the same thing to be true. Something was always teetering on done or had stepped off the cliff long before the OLM was DOA. In fact, I found about a thousand mile difference between summer and winter. That is during the winter half the OLM was STILL too long. Even the severe schedule was to long in the winter.   Now having done the work I can say I was NOT DISAPOINTED. I saw nothing I didn't already know. Nothing my father hadn't already demonstrated in his 2K OCI's pushing dated iron on dated oils and weak filters to mileages well beyond 300K.   Building on his work through use of Lab testing it wasn't hard to find the correlation between 'sight/feel/odor, the things dad relied on, and test results. Use of current viscosity stable chemistries & filters has pushed that marker for my motors out to 3K summer, 4K winter.    So the early lies were 3K on conventional oil and the lie upon the lie was 7K+. turns out to be off by a factor of two.    So... it is true that modern chemistry has doubled the useful oil life. But the base milage that came from was off by double. It's how good lies work. Partly true, sometimes mostly true so that your meter isn't set off. It also means that non-shear-stable shelf oils are only now as good as the old oils were in their best case scenario.    So the question now is how do we improve on that? Thus the question into cleanliness among the other items listed in the post quoted below.    If this bores you, feel free not to participate.

      2027 Chevrolet Silverado: Official Discussion

      By newdude · Posted

      Is it though?  Like LTZ, not a high take rate.  Current Sierra has AT4, Denali and Elevation as its main bread winners.  Each trim accounting for 25-35% of sales for Sierra.  SLT makes up about 10-15% at best.        Like others have predicted here for GMC, it will be:   - Pro (equal to WT Chevy)   - Elevation (replaces SLE and SLT)   - AT4 (and X)   - Denali (and Ultimate).
