Out of stock...

Also - to get how many amps that 300 watts will pull, simply divide 300/12 and you get 25. Technically you could divide by 13.8 because that should be a running car's voltage, in which case, your amps would be about 22 amps.

So if your cigarette lighter has a 20 amp fuse, it would blow if you pull a full 300 watts (or more for peak)

You're assuming the inverter is 100% efficient. They are typically 90-97% efficient, so the current draw will be even more at full load.

I have learned after a couple of tries these things are kinds useless except for charging a ipod or something. I have a 400W and a 150W. Almost everytime my son plugs in his laptop, it alarms. Why? Because the Laptop would pull more watts then the default for having it plugged into a cig lighter outlet. If you want the FULL wattage, you need a DIRECT connection to your battery with a 8 guage wire.

You can't get more than 100-150w through a cigarette lighter outlet with its 10 or 15A fuse, but that should be fine for a laptop. Some cheapo no-name inverters have the low battery alarm/shutoff set way too sensitive, and can't be used without the engine running. I have a 150w and a 250w that give me no trouble, but a cheap 300w unit I have is unusable with even a light load without the voltage boost from running the engine.

I had to wait 20 minutes to chat with an agent, but I got their promise to correct the price after the fact and managed to get my order in. The chat window disappeared only a second after I captured the text!
