Re: Why do the fuses blow out every time I plug it in
Watts divided by volts equal amps so 400watts devided by 12 volts equal 33 plus amps if wires and fuses wont handle 35 amps they will blow to keep from burning up the wiring of your vehicle

when replacing fuses in a device....if, when you next apply power to the device and it immediately blows the fuse again : Do NOT put in anymore fuses. It is time to visit a TV repair shop.
First make sure you have the right size fuse in it look at your owners manual it should tell you what size to put in there sometimes people blow a fuse and replace it with a weaker fuse it will work for a while till they plug something in that overloads the fuse then blows and if they sell the car the new owners don't know this they just keep replacing it with same type fuse that's in it. Second make sure whatever it is you are plugging in doesn't have a short itself try plugging in something different and see if it blows then if it doesn't then you know where your problem lies.
use the process of elimination, disconnect both headlights at the bulb and put another fuse in it and see if it blows. if the fuse blows without the headlights plugged in then its the wiring to the bulbs. if the fuse doesn't blow while the headlights aren't plugged in try plugging the lights in one at a time to see which headlight or socket is shorted. possibly corrosion at body to ground connections near the headlights, you may not see the corrosion, remove the ground wires and sand those ground wires down..
1.Unplug your taillights at the sockets and the front running lights from sockets.
2. put in new fuse after unplugging taillights.
3 turn on taillights if fuse blows then the wiring is grounding out somewhere between the switch, fuse panel, and rear and or front parking lights.
4.If fuse does not blow then plug in one socket at a time keep rechecking fuse. when the fuse blows after plugging in a certain socket suspect that one to be bad and replace.
Does the fuse blow every time you plug something into it? I guess what I'm getting at is it possibly your phone charger only, or does the fuse blow when someone else plugs thier charger in (different charger)? I guess if the fuse blows, no matter what you plug into it, I would suspect the charge port itself. Does it seem like it's loose in it's mounting bracket? You may have to replace the port.
Vacuum works with the battery but does not work with 120 volt. Every time I plug it in it blows the internal fuse. I have replaced the fuse inside the vaccum several times and every time i plug it in it blows. What do you think it could be?
