The Sunforce 1000 Watt Pro Series Pure Sine Wave Inverter converts DC power into clean, stable AC power. Excellent for powering home appliances directly from your 12V battery, this inverter will supply stable power to run small electronic tools, air pumps, electronic doors, small motors and refrigerators that a modified sine wave inverter cannot. Pure Sine Wave inverters provide clean power with very low harmonic distortion, no static or humming noise. With a peak surge power of 2000 Watts and continuous power of 1000 Watts, this product is the ideal solution for power failure emergencies and guarantees optimum compatibility with sensitive equipment, computers, motors, televisions and more! Compact and portable, this inverter is perfect for use at worksites, on boats, or for permanent use in a solar power setup. The 11240 features numerous safety features including an overload alarm and LED light, a soft start system, low battery shut down, DC input overload voltage, output overload, overload temperature, short circuit shut down, and a high speed cooling fan. Equipped with two 110V household electrical outlets, this inverter is so advanced that it is patented. Your purchase comes with a DC/AC power inverter remote control modular connector cable and key chain remote.

On a slightly negative note, I tried to recharge my MacBook Pro and some crazy stuff happened to my Mac requiring a restart so I am spooked and unsure about this being Pure Sine Wave. This should be put on an oscilloscope to make sure that my problem wasn't a fluke so I'm making no premature judgement here, just noting one event.
I have never heard the cooling fan run so I assume it is barely heating up.
P.S. Nice touch Sunforce with the fake plastic cooling fins. At least they make it LOOK cool! ;)
Pros: Cheap, sine wave power. Cigarette adapter on the front for easy connectivity to smaller items.
1. Cheap plastic sides are not heat sinks. I replaced these with sheet metal sides with flanges for mounting. Cost $60 for fabrication.
2. Cheap plastic knobs to secure DC connections. I replaced these with 8mm x 1.25 nuts and lock washers.
3. Remote switch as very short power cord. Seriously? I happened to have the wire and connectors to lengthen this. It was a joke.
4. Dual AC plugs on front. These are not bonded together. So if you want full rated power, you have to build a harness for the outside, or else rewire it internally. I have not had the time to check which option is best.
Bottom line is I would not buy this again. I would look at grid tie inverters instead. There are a number of these that are inexpensive and can be bonded together.
The ironic thing is the cheap Harbor Freight modified sine wave unit it replaced ran the microwave, and it costs about 1/4 of the Sunforce.
Someday when I get time I will use a current probe on an oscilloscope to see just what the startup current on the microwave is...if its less than 2000 watts then I'm very disappointed. The quoted watt readings were measured with a Kill-A-Watt, wish it had a peak capture mode.
Oh- Sunforce needs to ditch the fake plastic cooling fins on the sides..makes it more difficult to mount than it should be.
UPDATE- after almost a year of use the unit developed a problem. The AC output seems ok but it is somehow putting interference back on the 12V buss powering the unit. I noticed recently none of our 12V cig lighter cell phone chargers will work when the invertor is on line, they used to work fine. Substituting our older Harbor Freight 2000W modified sine wave invertor I do not have this issue.
Now the really bad part- I contacted Sunforce and was issued a RMA and a UPS account number to send the unit back to them for evaluation. Problem is I found one cannot use a recipients UPS number to send a package unless the SENDER also has a UPS account. I left both a voice mail and emailed them about this and perhaps getting a prepaid UPS label sent to me. In over a week, they have NOT responded to me for either message.
I was planning to buy their more expensive higher power invertor as an upgrade (see microwave problem noted in original review).
Not going to happen now with customer service like this.
FURTHER UPDATE- Sunforce is really difficult to deal with. I eventually got them to send me a prepaid UPS label, which took a month of asking, and sent the unit to them. It took another month from when they received it to finally replace it, and this was only after several inquiries. So total of over 2 months just to handle a warranty issue.
The first problem - starting at 1.5 years - the display gradually went crazy at first a few of the numbers on the screen stayed on but eventually they all came on. I called product support who told me that there was nothing they could do to fix it and no danger of anything bad happening from a defective display. The device continued to function normally (I checked it with a meter) for another year/
After 2.5 years the devices began to make a slight buzzing noise that gradually got worse as time went on.
After 3 years the buzz was hard to ignore and the fan ran continuously and things I plugged into the unit would flicker.
I replaced it with another brand of inverter, put it back in its original packaging and will likely try to recoup some of my costs by selling it on an online auction website to someone who is willing to fix it.
