Does anybody know how many amps a heater like this typically draws? Trying to fuse it correctly.

It is a 180 watt heater. 180W / 12V = 15A. You will need a 15 amp fuse if the heater is the only thing on the circuit. If you have anything else drawing power on the circuit a 15 amp fuse will probably blow.

The breaker size depends on the wire size used going to the heater. This heater only requires 8 amps at 240 v. #14 wire with a 2 pole 15 amp breaker would work. #12 wire with a 2 pole 20 amp breaker would also work.

NO. this does not draw enough amperage. Hooked mine up with a 20A switch with a 10A fuse. Works great.

Use a voltage meter to check for 12v at the connection between the long wire and the short wire going to the heater. If you do have 12v there then there is a problem with the heater itself. Otherwise I think there is a fuse in the part that plugs into the cigarette lighter. The circuit that supplies the cigarette lighter usually also has a fuse on it.

800 watts/120 volts = 6.7 amps for the heater. Current draw for the controller would be vey small.

Hi More than enough if I counted my fingers correctly (ha ha) those two should draw less than 5 amps together(4.7 amps) this power supply will more than run the lights. You picked a good choice! I have one, love it!Oh! I almost forgot make sure you are using #14 gauge multi strand wire with an inline fuse holder with a 5 amp fuse it it blows go to 7 amp fuse.

I ran an AC unit off this that was rated at 6.3 amps (+ surge) and it got slightly warm but not a concern........if you can afford it, i would get the next one up from this unit......however, this may work, but the hotter it gets the less life it may have/ possible fire hazzard

I installed the heater in my old 1976 beettle and it Works great. I don´t think that is necessary to put a new higher amps fuse. Plinio

We don't know where or how to measure the amps on this unit. I plugs up to the regular household 120V socket and so far at high brightness and full heating power - no power failure yet. It is too early if the heating will raise the cost $$ of the electric bill this Winter, on top of the usual townhouse heating system.

Assuming you live in the US and you are using a resistive heater (most likely), 120V (A) 15 Resistive Amps (copied from product description), P=IV, 120*15 = 1800. Seems good to go!

I really can't tell you that. But I use mine for powering up electronics. I run a peak of 55 amps, and continious amperage of 45 amps. I have run it at these amps for as long as 6-7 hrs. with no problem at all. Unit does not even get hot at these amps I am pulling from it. Also, a lot would depend on how many watts your heater is. I am sure your electric blanket would not pull anymore than 4-6 amps. I really don't think you would have any problem with it at all!

I have some experience with this. I have a 1000W (low) to 1500W (high) ceramic heater plugged into this unit and have had no issues with it running through two prongs compared to three.

I have used both heaters at the same time. I did replace a fuse once but it was because I left one plugged in. I think it's supposed to have an auto shut down but it didn't and burned out the fuse anyway. I have an adapter which I can plug both heaters into and I don't think it shorted out. hope that helps.

I used a 10 amp fuse and it worked very well. My amp meter never pulled more than 5.5 amps in any mode. Hope this info helps.

Easily, normal draw is under 15 amps. Set one up in a camper on a 15 amp circuit and at full output the fuse never popped

It limits. I have a device that pulls to much and it just stays warm, while only drawing max of 6 watts from the wall. I calculated this at 1.17 amp, which is as advertised. Used it a couple days at max (waiting for the 3 amp unit to arrive) and it didn't crap out.

Fuse does not have size, it is a glass fuse and the amperage should be approximately 1 amp. You can get a spare by taking to an auto supply store to get correct size, I am an electrical engineer, so the power calculation indicates a 1 amp fuse. Do not use this device on any heat loads.
