Go Power! 300-Watt Pure Sine Wave Inverter takes 12 volt DC battery power and converts it to an exact replica of AC houshold power. It is guarenteed to run any load within their wattage range and has a 2 year warranty for New unit (Refurbished units come with a 30 day warranty). This inverter has two GFCI outlets and includes cables to connect to the battery with ease. As long as the load is not greater then 300 watt this inverter will run it and the GP-SW300-12 can surge to 450 watt as well as contains all instructions required.

i confirmed with a scope it is a true sign wave unit and the THD is well below 3%so i have zero complaints.
Still working, not used 24x7, I will say. When I do use it, I still love the low idle draw. It runs a circuit at my cabin that only has some LED lighting and some cell phone chargers. Very friendly for running all night while I sleep without a big idle draw and noisy fan, but instant power when needed.
Finally got around to checking into the warranty on this. They are in Canada, so after contemplating shipping this heavy brick, the possibility they won't cover the warranty and I'd have to pay shipping back, the fact they say they don't ever repair the units, blah, blah... Ugh. In my case, the unit does not put out any AC, but the Power Status light is green. Sooo, I took a chance and popped this open and determined that the GFCI outlet was bad. Had a brand new spare sitting around, so within about 5 minutes and a $5 part, I was back up and running. They used a standard GFCI outlet and actually cut parts of the tabs off to make it fit, which I had to replicate on my replacement, but we're talking 20 seconds with some side cutters here...
This bit the dust the other day. Removed one star for that. Will see how good the warranty is...
As with many of these types of products, time is where the good products stand out from the bad ones.
However, I did want to point out that as of right now, I am really liking this inverter. For the price, it has great features and seems like a very high quality unit. DC power cable in box, GFCI outlets, remote switch, extremely low idle draw and great efficiency are some of the things I was impressed with.
Idle draw was a paltry .23A @ 12.24V or 2.81W. With a ~6W rated LED fixture attached, draw was .75A or 9.18W. This was purchased for some basic LED lighting needs and it excels at that.
Another highly rated sine wave inverter I purchased has a higher rating of 600W, so is not a fair direct comparison at low loads, but the point must be made that it bounces between .15A and .8A at idle and is steady at 1.22A with the above LED light attached. In my case this Go Power! inverter really stands out in comparison for this use case.
This unit appears to be identical to the Samlex 300W inverter, SA-300-112...
I tried a number of "Pure Sine Inverters" and found that the quality of the sine wave is highly dependent on the amount of load. Or they only produce decent sine waves into a resistive load. In any case I went through three before I found one that would run my device. This was it.
The GP-SW300-12 provided power clean enough to run my very picky machine, and I suspect it will run pretty much anything you throw at it as long as you don't exceed the load rating.
I can't verify the ""300 Watt"" rating as I was only using it at about 170W, but at that level it ran quiet, cool, and happy.
