Schumacher 750W AC to DC Digital Power Inverter for Cars - Convert Vehicle Power to Household Power Efficiently Review

Bought from Walmart then online here and there are others that have other names, this one is by far the best and the one at Walmart was the same as this one but the Walmart version had faint lines.

This item worked very well for 4 days. Now it goes off after 10 minutes. Input 13.5 volts DC. Load less than 100 watts at 120 volts AC (output). The item is indoors and out of direct sunlight, temp 84f. I don't know who to contact for service.

Not a bad unit but not very accurate in its readings . The display shows an input voltage of 12.4 VDC and my voltmeter shows 12.7, the device shows an output voltage of 120VAC but my voltmeter only shows 109-110VAC. Modified sine wave is good for everyday use but not for motors, switch lighting, LED lighting or anything with ballast including heavy motors. It wears them out prematurely. This is also in the instructions, as I found out after the purchase.

I have two of these. I keep one in my work truck to charge my drill and my laptop batteries and the other in my camp bag for wherever I want to use it. Considering these are less expensive devices, I'm happy with their performance. I've even had to run small 120v saws with one and it worked fine. I don't recommend it, but it worked. The fans are quite noisy and the unit is sensitive to voltage fluctuations on the 12V sockets in cars, but for general light use mine worked well enough.

Here they are: 1) The unit is LOUD, like an acid metal orchestra. stoned at the last concert of the tour - when the power is about 50 watts or more. 2) "Low Power Shutdown" has two problems: A) it shuts down too quickly and easily; I couldn't tell exactly where it turns off, but at that voltage level it only takes a moment to turn off (for example: if something turns on in the truck that the voltage drops for a second, this thing is working). B) No restart - after a power failure, it will NOT…
