{"text":"Hi, our boss banned the use of power converters in trucks after one driver burned his truck.\nI need to connect a coffee maker 120V 700W. \nWe drive Volvo VNR 2021. I saw once a driver drawing power from the front console. Can I disconnect a radio and use this cable to connect to coffee maker? Is there appropriate voltage?\nAny advice? I don't know anything about electricity at all","videos":"[]","link":"{}","pics":"[]","canComment":true,"externalShare":false}

{"replyTo":"","text":"I wouldn’t recommend tapping into the radio wiring for a 700W coffee maker that’s way too much draw for those circuits. You’d be risking melted wires or even a fire, which is probably what your boss is trying to avoid after the last incident.\n\nA 700W appliance at 120V pulls around 6 amps, but at 12V your truck’s electrical system, that jumps to about 60 amps, not counting losses from inverting. That kind of load needs to be wired directly to the battery with proper gauge wire, a fuse, and a pure sine wave inverter and even then, your boss banned converters.\n\nBest bet? Look for a 12V coffee maker made for truck use. They’re slower, but safer and within the limits of your truck’s electrical system. Don’t mess with factory wiring unless you know exactly what you’re doing  could cost you your job, or worse.","replyToPid":0}

{"replyToPid":0,"replyTo":"","text":"Your best bet is to have a talk with your boss, and see if you can convince him otherwise. lots of trucks are factory equipped with power inverters, they're perfectly safe when installed and used correctly.\n\nOutside of that, you're probably gonna want to look for a 12 volt coffee maker that plugs into the cigarette lighter receptacle at the front of the truck, although those 12 volt coffee makers aren't particularly known for working all that well. \n\nAnother option, would be to get an inverter that's on the smaller side, with some battery cables with clamps that can be temporarily connected to your batteries outside the truck while you run the coffee maker, then disconnected and hidden away somewhere when not in use...\n\nAnother option would be one of those \"portable generators\" which is basically just a large lithium battery with a built in inverter that you could plug a coffee maker into. ironically more dangerous than just having an inverter on board, but your boss would likely be none the wiser. you'll have to size it depending on how often you can get somewhere to plug it in and charge it, unless you get one that's capable of charging with a 12 volt cigarette lighter plug, so keep that in mind.\n\nAnother option, a favorite of mine, would be to use an old fashioned percolator on a portable gas camping stove, alot of truck stops even sell the butane canisters that they use. you could also just do it the old old fashioned way in a sauce pan, although most people are not like myself, and dislike that sort of unfiltered coffee. I like it myself, and actually made it that way despite having a coffee maker in my truck...\n\nJust be careful and exercise common sense. I hate to tell someone to just go for it, considering people have varying levels of expertise. that being said, my advice to you is; when in doubt, don't. I hope everything works out for you, good day."}

971654 发表于 2025-04-10 22:39:48 Thanks you two guys for the substantive explanation. That's why I'm writing here because I know that old fashion truckers know a lot about truck electrics and I don’t want to and I don't want to do it without your knowledge.

","text":"well, excuse me, Brett. I'm happy with folgers. If you're so sophisticated and snobby on something as simple as coffee, go to a real mechanic and wire in an inverter. Although anyone with even the slightest brain capacity should easily wire one in without overloading or shorting to ground and burn a truck down. but I digress. Do you have different flip flops for driving and fueling and truck stop entry? I can tell you have no duck tape, bailing wire, zip ties or even the most basic set of tools.","replyToPid":484118}
