This immediately caused the15 amp cigarette lighter/radio fuse to blow. How many amps is this product rated for? Is there anything I can do to fix it?

I am wondering if you were overloading the circuitry. If you have a powerful radio or premium sound system, it can draw significant power, so if you were using more than the USB charger functionality, the 110v socket, you have to do the math. 150W is the rating. If the car was running, you charge at about 13.8V, and watts equal volts times amps, W=V*I so amps = watts divided by volts. Amps = 150/13.8 = 10.9 amps. If the vehicle was not running, then the amperage changes because the input voltage changes. This would be 150/12.4 = 12.1 amps. Of course this is at maximum load. If you add the all of the cigarette accessories together, you're allowed 15 amps. This leaves only 3.9 amps for your radio and any other loads that may be on the cigarette lighter, such as other phone chargers, gps, mp3 player, etc. I was able to use this inverter to run a crockpot on low through an extension cord to the back seat floor, while using a GPS and playing the radio at a moderate volume in a Ford Explorer without any fuses being blown. I suggest trying it by itself and powering only ONE device through the 110V socket that operates at a maximum of 150 watts. Devices with electric motors such as fans and compressors can draw double the current (therefore watts) when it starts up and this is called Peak power consumption. Try it with something without a motor if possible.

I would NOT buy this product. Mine is brand new, used it twice and blew the fuse in my car twice. It is now collecting dust in my garage.

I do not know amps fuse is rated for, but have had the product for several months and use it regularly; and have had absolutely no problems with the unit (fuses or otherwise).

Most Cigar lighters work for these however in my case I use it in heavy equipment. To warm up my lunch on the go so it works well for that. I couldn't say if it works in all cars but most lighter have 15 amp. to 20 amp.fuses

Amperage draw is 19 amps max, so you could clip the alligator clips to the lead wires on a cigarette lighter adapter as long as your cigarette lighter circuit is rated at 20 amps. I looked at the fuse on my Chevy pickup, and the lighter circuit is only rated for 15 amps.... that could cause a blown fuse if the compressor is working at full load.

Mine came with a 5A 250V fuse. Either way if yours comes with less, a 5A is appropriate to install as most cig lighters are fused at 7 - 10 amps and no radio should use more than 2 - 3 amps unless it is "modified."

You need a 15 amp and ,If this one blews try the 20 amp fuse. but the 15 amp is the right fuse for it. Eddie O. Murray, Piedmont,Alabama

I would go to fuse panel an pull off the lighter fuse if it was me...there should be a pin that in the kit that does this....

Patrick: I cannot answer your question directly except to say that I looked up the spec's for your radio and it says that the vehicle power cord for this unit is rated at 5v output so it shoud work properly, (especially if the plug going into the radio fits properly). I hope this helps.... If it blows out the radio, then there is too much power going to the radio. If on the other hand, the power cord blows out and NOT the radio, then there is too much power going into the adaptor and it will blow the fuse therein. Make sure you only have 12v going into the power cord fromt he vehicle's battery.

late reply here: I was installing this as a trunk release in my car today and during a bench test I found that this motor pulled up to a max of 4.1 Amps when full extended or compressed (leaving it engaged for more than 2 seconds)

Do you have one of the cars that require the key/engine on to power the cigarette lighter? Check and reset your auto fuse/breaker. If not tripped then bad contact/wire break somewhere. After that I have no suggestions.

If you draw too much current, it will blow the fuse. Otherwise it should run indefinitely.

Make sure you haven't blown the glass fuse in the cigarette lighter adaptor(little 1.5 amp fuse if I remember it correctly)That fuse is located just inside the plug that you'd insert into your lighter socket. Also make sure your cig lighter/accessory socket itself hasn't blown the fuse. If both of these are good, your unit is toast. You can get a remanufactured one from Magellan for about $80, but I have not had good luck with them (these things are notorious for going south every time you upgrade your maps).

After seeing Vicky's response, I see what you were asking now. However that wall plug only supplies 500ma. The compressor is fused at 20 amps and most cigarette lighters supply 10-15 amps. Therefore the adapter wont supply enough current to drive the compressor or may even blow the adapter's fuse. Looks like its designed to drive phone chargers and electronic devices. If there is one that supplies the equivalent amperage as a normal cigarette lighter socket then go for that one.

I beilieve its a 15amp...not indicated...however, I've done three heavy duty fillups with it and have had now problems...my 2001 Sierra's outlet is the cigarette lighter which is notoriously lame and has not blown a fuse

I installed inline to the cigarette lighter using a .5 amp barrel fuse. I don't think it even draws that much power, but can't remember since it has been such a long time.

Be sure the circuit (fuse) has the capacity to handle the load. I have an aux. battery in my van and charged from a Wagan Quick Jump Starter and it blew a 20a fuse after a couple of days of plugging it in. Be sure you isolate the aux battery in some way or your batteries will try to drain each other.
