Review on 🔌 400W Power Inverter - 12V to 110V Car Vehicle Inverter with Dual USB Ports and AC Outlets for Road Trip, Cigarette Lighter Inverter by Tutan Hesch

I'm not an electrical engineer, but I'm no stranger to inverters. So I realized that the listing for this product was vague and most likely misleading even before I ordered it, but I was willing to give it a try because I was planning to use it for a slightly different purpose as he is progressing at Revain . This misleading product is "in your car" performance. I've tested it and confirmed that it can handle 250-300 watts AC with ease. However, if you plug this device into your car's cigarette lighter and try to boost it to 300 watts AC, you will be trying to get about 25 amps of DC through the fuse in your car. Some trucks and SUVs have 25 amp DC cigarette lighter sockets, but most cars, especially sedans and crossovers, only have 10, 15, or sometimes 20 amp DC outlets. If your outlet is rated for 10 amps DC, the maximum output you want to get from this (or any other) inverter is 120 watts AC (a 15 amp outlet maxes out at 180 watts AC and a 20 watt outlet ). , amps are maximum at 240 watts AC). If you try to use more electricity, your car's fuse will blow. If you want to use the full 300 watts, you'll need to invest in a set of cables (probably alligator clips) to connect it directly to the battery, bypassing the cigarette lighter entirely. Many similar inverters listed here at Revain add a disclaimer to the product listing explaining this limitation, but there is no such disclaimer here as I write this review. Another misleading thing in the listing of this product is the power rating. "300-400" watts AC I could confirm is somewhat correct (albeit poorly explained) but the listing also says it can handle up to 800 watts AC "continuously" (start/rise), and that's pretty much just outright lies. I bought this product to keep my internet gateway/router running during a power outage, so I made my own 10AWG wires (larger wires, more efficient power transfer) to connect the inverter directly to the 12V connect the lawnmower battery. In my own inverter performance test, I used several different fans (70W each), an LED lamp (10W) and a belt sander (180W). All of them worked individually, even the belt sander. When I plugged them all in at the same time via the Kill-A-Watt meter, I could see that instead of the 330 watts AC needed to run all the devices, the inverter was putting out about 280 watts AC, sometimes as much as 300 watts AC. This suggests that the appropriate maximum "working power" for this inverter is actually only around 300W AC and is probably closer to 250W AC if you want everything running at full efficiency, thereby risking wearing out your devices is reduced. . Most likely "start"/"inrush"/"intermittent" power for this inverter is closer to 350-400 watts AC. That's exactly what it takes to get something like an engine turning. Such loads consume less power after starting. In principle, I do not accuse the seller of lying about the characteristics of the inverter, but I have the impression that they did not know how to correctly convey what the inverter is capable of. They didn't realize that the inverter could actually supply more power than most cars could safely draw. So if you don't "squeeze out" this inverter, it should work just fine. In fact, you should see pretty good performance until you "overclock" the inverter, as inverters tend to perform best at around half or less of their rated maximum. And while the rating will be low from me, it's also fair to say that this device looks pretty well built, at least from the outside. The main body is aluminum, it has a fan for heat dissipation, the sockets seem solid, it puts out REALLY 300 or so 300 watts AC which is more than enough for most suitable applications (connected via cigarette lighter). ), and the included cigarette lighter cable is marked 2.5mm2, which is a metric size that's roughly 14 AWG US standards - small, but probably enough to drive a 25A DC amp if the cigarette lighter socket your car supports this. Vine Reviewer, I received this product "for free" in exchange for a helpful, detailed review, but expect to provide an honest review, good or bad, and I take that claim seriously. As far as I know, the seller's inability to clearly communicate the parameters of the inverter is a disadvantage that costs him a star. Even though "maximum" inverter power is advertised, the package does not include a direct battery cable, which is required to utilize the "maximum" power of the inverter. If the package does not contain all the necessary parts for full use of the product, this must be clearly explained, otherwise it will simply mislead the buyer. It costs her another star. The fact that a product appears to be of high quality suffers from the way it is presented in the wrong light.
