The YSOLX 1000W inverter (model MT-MX1000) is the model I kept coming back to while researching this brand. It has the deepest pool of independent reviews of anything in the lineup, and the feedback is specific enough to actually trust. Here’s what I found.
Specs at a Glance
| Continuous power | 1000W |
| Peak power | 2000W |
| Input | 12V DC |
| Output | 110V/120V AC, modified sine wave |
| Outlets | 3x AC sockets, USB-C and USB-A ports |
| Dimensions | 8.27 x 5.51 x 2.58 in |
| Weight | 3.08 lbs |
| Warranty | 18 months |
What Buyers Liked
The number that stood out to me: one independent tester measured the output at 115V “even under a hard load,” which is close to a real wall outlet. That matters because a lot of budget inverters sag badly once you actually put weight on them.
The same tester ran a 48-inch TV, a PS4, and lights off it simultaneously without tripping the unit. That’s a meaningful stress test for something in this price bracket.
Buyers also called out the setup as genuinely plug-and-play. It ships with battery clamps and a manual, and reviewers described it as compact enough to fit under a car seat despite the 1000W rating.
What Buyers Complained About
The cooling fan runs more often than reviewers expected, including at lower loads where it doesn’t seem necessary. It’s not a dealbreaker, but if you’re using this near where you sleep or work, it’s worth knowing going in.
The other recurring theme wasn’t really about this specific unit. It’s that YSOLX is a newer name in a category where brands like BESTEK have years more of a track record. That’s a fair point, and I go deeper on it in my brand comparison.
Safety Features
- Four built-in 40A fuses (two spares included)
- Low-battery automatic shutdown with warning light
- Over-voltage, low-voltage, overload, and short-circuit protection
- Reverse polarity protection
- Temperature-controlled cooling fan
Who This Is For
This model makes sense if you want backup power for a TV, laptop, mini fridge, or lights during a road trip, camping run, or home outage. It’s a modified sine wave inverter, so skip it for anything with a motor or heating element: hair dryers, coffee makers, curling irons, and similar appliances aren’t a good match, and the product listing itself warns against them.
If you need less power for lighter charging duty, or more for running tools, I compared every wattage in the lineup in my buying guide. For general upkeep once you’ve bought one, my usage tips cover what shortens an inverter’s lifespan.
Verdict
For the price, the YSOLX 1000W delivers real, tested output and legitimate safety protections. It’s not a premium pure sine wave inverter, and it’s not trying to be. If you know what you’re powering and you’re comfortable with a newer brand backed by an 18-month warranty, it’s a solid pick. Before you buy, check where you’re buying from, since I found several third-party listings marked up well above the official price. My buying guide covers which listings to trust.
