   While this is a very ‘no frills’ inverter, what it does, it does very very well. So, there’s only one grounded AC outlet and one ungrounded, but I knew that before ordering it. The ungrounded outlet allows for the type of plugs that have both prongs of equal (smaller) width. Accessories, like phone charger blocks, and the likes, have this style. Other items, like the heater in the video I’m attaching don’t, so it had to be plugged into the grounded outlet. The LCD display is fantastic for such a basic unit. The case, all aluminum, no plastic (besides the lug nuts, which is the norm). The inverter is quite compact and it’s really designed for portability. To this, it has a handle for carrying it around and the cables provided terminated with ring terminals on one end and battery clamps (large alligator clips) on the other. Plugging in to the grounded outlet the first time required some force, which can be seen in the video. The ground terminal part of the outlet is pretty tight. That’s not anything for concern, but I’m mentioning it as you can see in the video, so I figured I’d mention that you should probably expect the same.

   Regarding performance, I’m impressed. It powered a 1000W heater, that actually can cycles above 1000W occasionally, very well. The internal fans on the inverter kicked in shortly after applying the load, but they aren’t offensively loud and they’re doing their job. The wave form is in the range of pure sine, with just a tiny bit of noise. I wouldn’t hesitate to run electronics through it, or my 12V fridge, etc. The only beef I have with the unit is the manual only calls out specs on versions, that this is not. Listed is only the 700W and 1200W versions, so the manual is worthless in my opinion. Still, this inverter isn’t worthless, it’s actually quite nice. You can always extrapolate, guesstimating what 1000W would spec at, but still… As for the price, it’s not the cheapest 1000W inverter on the market at $119.98, but honestly, nothing about this inverter feels cheap. I’d gladly stick it in a portable solar generator. We’ll see how it holds up. If I run into any issues with it down the road, I’ll update the review.

   Tested it out and it seems to work okay, tried connecting it to 2 different LIfePO4 12v batteries and the AC output voltage was showing 114v on the display screen, also said 60hz and I have to assume it is a pure sine wave as I don’t have a sine wave tester.

   The cables are heavy duty I just wish they already had the alligator clips connected to the wires but not a real big deal.

   This can work good if you need AC power too far away from an outlet and also if you have a power outage.

   I have been lucky enough to never have an issue with power surges when using our solar panels, but I got this for peace of mind. It was easy to set-up and is made of quality, durable materials. It isn’t super heavy or cumbersome. It seems like an awesome value for the money.

   I have only tested this inverter with loads much lower than 1000 watts because I don’t have a high current battery available. I was able to use it with a 15 amp lithium battery to power a 150 watt load without any problems, but I’ll need a much larger battery to push it to its limit. The display is nice — it shows battery voltage, AC voltage and power draw in watts. There are two AC outlets: one 2 prong ungrounded, and one 3 prong. I appreciate that this inverter came with battery cables. For 1000 watts at 12 volts, they will be carrying 85 amps, so the cables should be at least 4 AWG. The only labels on the wire are the name of the wire company (in Chinese), but they do seem to be the right thickness for 4 AWG. One side has large lugs that fit the connectors on the inverter, and the other side has smaller lugs that fit the supplied alligator clips. I would have preferred large lugs on the battery side because the clips seem like a weak link, but they are certainly better than nothing. Construction quality seems good for the price, and it’s pretty reasonably priced for a 1000 watt inverter.

   I’m building a foamie out of some experimental materials, and I wanted a good inverter, so I thought I would give this a try. Excellent choice. This inverter is well made out of good quality materials. Fit and finish are good. Easy to hook up and use. Display is clear and easy to read. Works well. Highly recommend. 5 stars.

   When I first received this inverter, I was surprised how small and light it was. Once I hooked it up and ran it through my tests, I was impressed with it’s efficiency and how quiet it is while running.

   I hooked the inverter to a 600W heater, and a 12V solar battery. The battery started at 13.2V, and the output voltage was 112V. Once the heater was turned on, it drew about 550W and brought the battery voltage to 12.4V, and the output voltage was still 112V, impressive for drawing that much power. Based on this particular tests, it looks like the inverter is about 93% efficient at 50-60% load, which is quite good.

   The display is bright and easy to read, and gives all the information you’d need.

   Overall impressive quality for the price, and I’m considering getting the larger models.

   This device has proven quite useful for my needs. I appreciate its solid construction and the clear LED display, which makes it easy to monitor power usage. I recently used it to power a small fan and a lamp during a brief power outage, connected to my solar panel setup. It worked flawlessly, providing a steady flow of power. It gives me peace of mind knowing I have a reliable backup power source.

   I was looking for an easy to use powerful inverter to charge batteries on the job site. This inverter worked well charging several batteries at once and had a audio warning when it started draining my truck battery.
