J'ai acheté ce petit onduleur 500 W. Tension de 120 V à la sortie avec onde sinusoïdale pure. L'écran sur le dessus fourni toutes les informations pertinentes, tension d'entrée, de sortie, puissance, etc ce qui excellent. Le ventilateur ne fonctionne que lorsque la puissance demandée est de plus de 200 W de sorte qu'à faible charge ou à vide, il est très silencieux. Pour terminer, il est équipé d'un démarreur à tension réduite "soft start" de sorte qu'il réduit la puissance demandée lors des démarrages de petits moteurs. Il ne manquerait qu'une protection DDFT pour être complet. Je suis très satisfait.

Inverter is bit noisy when the fan runs, I did not keep it as I have a 1000w which is quieter. It is a good product though.

Works as intended.
I review everything

This isn’t something at least in the 500 watt version that is going to run much when the power goes out — in SC we had a Hurricane go through that left my family without power for three days (some still don’t have power almost two weeks later) — I set up a little experiment with this and found that it will fast charge my rechargeable electronics and flashlights — I tried using the USB outlets in my car but that was not worth the gas at the slow charge rate — I can hook this right up to the car battery without turning on the motor and charge several items at the same time — with the display you can see the input voltage from the car and run the motor only when needed and verify the output voltage to be close to 120 VAC — the more devices you add the lower the voltage goes — I tried to run a corded drill and then my lawn mower battery charger with the same result — the output voltage dropped below 30 VAC and the inverter alarm went off as did the inverter — when I removed the load all was good again — of course the motor running requires the car to be outside — this is small enough that if the weather is bad you can put everything under the hood safely away from moving parts and heat — the input terminals need to be modified to get a tight fit on the wire lugs — the knobs don’t have deep enough threads to fully tighten down onto the wires — I had to put a couple of extra washers on the terminals to get a tight fit — there were three thin washers included so I would have only been able to get one side tight — I can use this for what I ordered it for so I am very happy with this inverter — go for a model that has a display, otherwise there is too much guess work and that would likely end up with a blown fuse

I purchased this one to use to power an antenna rotor when we are out in the field. I am so pleased that is hardley draws any current just turned on. The last time I purchased one was 10 years ago (Still have it and it still works just to big to take portable) my old one would draw 2.5 amps just turned on with nothing plugged into it. Man they have really improved them in 10 years.This one has a little problem, the watts on the display does not work it just shows 0000 no matter how much I draw from it. I like it so much that I am keeping it for my Radio room in the basement (I already have power usage monitoring set up, I run my entire Amateur Radio setup off solar power). I am going to order another one for portable and hopefully that display works. I need to know in the field how much I am drawing from my battery.For 69$ this thing is just perfect!
