Customer Questions & Answers

Does this unit have a on off switch or is AC power available as soon as 12 v is applied?

Asked by: Burbs
Yes, it has an on/off switch. However, I have discovered that it doesn't work well if the electrical load is applied before the unit is turned on. It is better to turn it on and then plug things in to it.

If I hook this unit up directly to a regular car battery, can I plug in a coffee maker and have it actually brew my coffee?

Asked by: Jerry
It depends entirely on how much wattage it takes to start your coffee maker. If your coffee maker requires more than a thousand watts to start, this will not work. If it takes less than a thousand watts to start and then requires less than five hundred watts to run, it will work. Remember though, if you hook it up using the cigarette lighter plug, you will only get one hundred watts max power. Probably not enough to run a coffee maker. Use the alligator clips direct to battery.

How long of a charge does it get when fully charged?

Asked by: whitefire
The unit doesn't "get" a charge if you mean "keeping or holding" the charge. It converts the power from your car (or other) battery so that you can provide power to various appliances. The unit can plug into the car lighter receptacle and power basic smaller electronics like cell phones and laptops. For items requiring more power such as camping accessories or power tools you would need to connect the inverter directly to the car battery. Connecting adapters are provided to allow both methods.

Rated 3 out of 5 by from Not Bad, Not Great. Does what it says. Product arrived shipped to store quickly but there was no one there to receive it. Delivery company had to make a second delivery attempt, even though the first attempt was made during the middle of the day. Box was opened by an employee before I picked it up. Not cool. Necessary hardware was included and of average quality. Inverter works as it should. However, I've only used it once so far.

Rated 3 out of 5 by from Would not work in my application Each time I plugged a 300 watt heater into unit a fuse would blow. Tried 2nd time same result. Did not try 3rd time. The unit would light a100 watt bulb but not run a 300 watt heater even though it was a 500 watt unit.

Rated 1 out of 5 by from Very Misleading discription on your website You advertise the inverter as a 500 watt inverter, but make no reference to the fact that it only pushes 100 watts when plugged through the cigarette lighter port which is what I need the inverter to do. This item is basically usless to me and I have now wasted money on a product that I can not use.

Rated 5 out of 5 by from love it! love this inverter! I have used many in the past and this one is the best so far! cool design too, so I don't care to have it sitting in the front seat of my car. I used it last time we had a power failure at work too.
