    • Working Flawlessly
Size: 500W
I have had this inverter connected to the solar power system in my off-grid cabin for over a year now. It has functioned flawlessly. It has recovered seamlessly from the few occasions where I have connected a load that exceeds its 500 W capacity, like not checking the current draw of my circular saw before plugging it and trying to use it. The first short cut worked with the inverter sounding a loud beep, using the inverter's 1000 Watt surge capacity. A second longer cut caused the inverter to shut down, but it immediately reset by flipping the power switch off and on. Exactly what one would hope for. When I am running four LED light fixtures, the fan rarely comes on. At higher loads the fan does come on and it isn't exactly quiet, but when I am using that much power I don't need silence. ... show more

It does what it's supposed to do. The display is neat too. Very useful. And it's pure sine — works great for running my fan and my PC, and my laptop all at once, off of a car battery

Size: 500W
Pretty good items. Took me a bit to get to use it. Seems to work ok. Didn't notice much noise coming from it. Pretty decent fit for the money. Wasn't to expensive and rates a decent pull. Nice thin design doesn't take up to much room.

But I hook it up via Cigarette plug and will run 60 amp Box fan ( 60W / 12V = 8A ). Power meter showed battery draw down 10.5 volts and Battery light bar indicating "Dead batter" which i know is IMPOSSIBLE with 2x 250 Ahr LiPo4 (500Ahr) batteries. I chalk it up to the 14 AWG wire limiting amps. _ Time will tell and "I WiLL be back to up date yet ANOTHER piece of China Product review!" ... show more

    • Great inverter, actually pure sine wave.

This inverter is a great value, it's actually pure size wave! It puts out 120v 60hz power, at idle with no load it uses .37 amps. I put a 400 watt load (inductive heater) connected to a fully charged group 31 AGM, the display showed 400 watts being pulled but doing the math it was pulling approximately 475 watts from the battery (that makes sense with the conversion efficiency loss). I will say the voltage display on the unit itself is always 0.2v off from actual under load. Overall the unit stayed quiet under light use (putting 400 watts on it did cause the fans to kick on continuously). I can't complain for the price, personally I will be making some thicker gauge battery leads for it since the ones it came with seem a bit thin for the 50-60 amps this inverter could theoretically pull which might be causing a voltage drop. (I took it camping for 3 days and it did great power my laptop/portable fridge and phone, even at around 100 watts of load I couldn't hear the fan and the unit itself stayed cool to the touch) (Packaging includes the inverter, alligator wires, and 12v power socket (limited to 120 watts in this form) ... show more

    • Packaging or lack thereof is the worst I've every seen.
Size: 500W
I bought the 500w and from the label it appears they use the same box for all their units up to the 800w. The inside cushioning is for the 800w so this smaller 500w is basically loose flopping around in the box. I wouldn't be surprised if many don't work out of the box . Very disappointed. There is a smell that irritated my lungs a bit, hopefully it goes away. I returned a different Chinese brand that also had poor packaging and smelled very strongly like a can of spray paint, this is due to a capacitor or a battery leaking. Hopefully this is not the early signs of that. The fan is very noisy, sounds like a blow dryer in low mode, it comes on around 100w of use on a warm day in my van and blowing that smell around, giving me a headache. It seems to go on full blast for 30 seconds, then stops ever few minutes or so which is annoying. Not variable speed based on temp. And it's blowing the fumes of whatever it is, it's toxic as my lungs are irritated by it and gives me a headache. Just the past couple of hours of this smell is really making me consider returning it if it doesn't get better in a few days. The two outlets should be orientated 90 degrees or flipped 180 because the way it is now you cannot plug in power adapters into as it needs to hang down but there is no room to do that when it is mounted on the wall or floor. I don't don't use the battery clips, I'd rather have a cable with bother terminal connectors on both ends. Pros: - I like the manual power switch - I like the display for the AC and DC voltage, and wattage being used, also the LCD lighting is always on a little too bright imo. Should have a timer to turn off or something. - I like the fused being on the outside and accessible as some are inside. - I like that is came with a cig adapter ... show more

I tried out the inverter in my 2011 Ford Transit Connect van. The van has cables in the rear compartment that connect directly to the battery through a dedicated 100 amp fuse box. I connected these cables directly to the posts on the rear of the inverter. I used this setup to power a standard Lasko box fan. The purpose of this rig is so my hound can enjoy a little breeze on trips to the dog park. The inverter seems to be working as advertised and would receive a high rating if it weren't for the fact that it is a used item. I had ordered a new one and can't imagine why they sent a used one. ... show more
