The product arrived promptly and in good condition.

I bought this in order to run the refrigerator and freezer during power outages and to run 120 volt gardening equipment (weed whacker, hedge clipper) without having to run a long extension cord. It is very difficult for me to start gas powered equipment and I need to take frequent breaks.

I get plenty of run time using my lawn tractor battery. For refrigeration, I parked a car outside the window, connected the inverter, and left the engine running. Plugging in the refrigerator (only 300 watts) tripped the low battery voltage protection, but I was able to reset and run the refrigerator.

Like virtually all inverters and some generators, it produces a "modified sine wave." Everything I have plugged in has worked, except for 2 UPS units. I use uninterruptable power supplies on my sattelite DVR and on my computer. Instead of just pulling the plug from the wall and plugging into the inverter, I had to unplug from the UPS and plug the units directly into the inverter.

The battery cables supplied seem flimsy. Ring terminals are used to attach to the inverter. The inverter's terminals are spaced close together, which could be a problem with heavier wire with larger terminals. I had to tape the wire and terminals because copper was showing and strain relief is needed.

You might think a generator would be a better choice, but it needs to be started periodically, fuel can go stale, and you need to guard against carbon monoxide. Manual starting is a problem for me, so an inverter is a better solution.

The bottom line: It does the job. When the power went out two days ago I was glad I had the inverter.

The man that did the first review (Allan Arthur) makes many great points. I use it strictly for convenience rather than fuss with a generator in bad weather, keeping it in good working order, etc. I can run everything I need for about 8-10 hours with two deep cycle batteries hooked in parallel. That may sound like a hassle all its own, and it was setting it up. I have the batteries hardwired together in my office out of sight. I have the inverter hardwired to the battery so when the power goes out all I have to do is run an extension cord to my living room where my computer and TV are and turn on the inverter. I can do that in two minutes. I also have a UPS, which gives me about 40 minutes before I even need to do that. Getting a generator up and running is going to take a lot longer than that.

Overall, this product is amazing for the price. You should look up the difference between modified sine wave and true sine wave if you have any specialty electronics that you need to back up. You would need to do that with a generator as well. True sine wave is going to set you back quite a bit. Modified sine wave works fine for most household electronics.

Great value if you don't run CFL loads off this one. In my setup, it was tripping randomly when connected to 4 23W CFL lamps. 2 other inverters I had did not so must be a problem with this unit. If you don't plan to run CFL lamps, it's a great product. I especially like that the fan shuts down automatically under no load...

I bought this to replace a B & D 400 watt inverter that has an irritating fan noise. The B & D fan would come on the minute you plugged anything into it.

This inverter has a bigger muffin fan that cycles on, then off when you switch on the inverter but then - under the same load conditions that I had for the B & D - never comes on again. It is higher and longer than the B&D and seems to keep cooler because the case is made of metal with cooling fins.

I am not using it under heavy loads yet but I can say that it is exactly what I was looking for. I am glad that it has twice the capacity of the B & D unit, even if I haven't needed it yet. Northern Tools sells an 800w unit that looks exactly like this but adds a USB charging port.

I expected much more from this inverter.

It cannot run a circular saw, cannot run a belt sander, cannot run a router.

The only thing I could get it to run was a fan, and if I put anything else on the line, it bogs the fan and shuts off..
If it's really 1800 peak, it should start the saw at very least, but it can't.

this is a great little inverter that i use camping with the rv or with my suv at parks ... the only reason i didn't give it a 5 star it should had a longer cord for battery & it should had a 12 volt charger cord with it ... works great on powering up tv, lights, & other things you use camping or tailgating

Voltage with no load reads 110.0. Voltage with 240 watt load AC reads 105.0. This low voltage may be unacceptable for use with a refrigerator.

I've had this inverter for several months now and overall it works pretty well. It does kick off sometimes when I am running my 600 watt coffee maker and a couple of small lights and such. Not sure if it's the lightweight cables that came with the inverter and connect to my golf cart batteries or what.
Anybody have any idea what gage those wires are?

HELLO BOUGHT THIS INVERTER SPECIFICALLY TO POWER THE 180 WATT BATTERY CHARGER THAT I USE TO POWER UP THE BATTERIES ON MY ELECTRIC MOTORCYCLE.

VERY DISAPPOINTING. IT IS A 900 WATT UNIT AND WHILE IT WOULD POWER OTHER 110 VOLT APPLIANCES, IT WOULD NOT RUN THE MUCH SMALLER DRAW THAT IS REQUIRED FOR THE ABOVE MENTIONED CHARGER. ONCE THE CHARGER WAS PLUGGED INTO THIS INVERTER, THIS INVERTER WOULD START BEEPING EVERY ATTEMPT.

FUTHER, I EMAILED THE COMPANY THAT MAKES THIS UNIT 2 WEEKS AGO AND I HAVE NOT HEARD FROM THEM.

I BUILT MY OWM SOLAR PANELS, AND THEY WORK FINE. I PUT TOGETHER SOME 12 VOLT BATTERIES POSITIVE POSITIVE TO POSITIVE ETC. MY GOAL WAS TO HAVE ONE SOLAR POWERED RIDE ON MY MOTORCYCLE THIS FALL BEFORE IT WAS TIME TO PUT IT AWAY.

THAT DIDN'T HAPPEN.

I DID MY PART, BUT WAS LET DOWN BY THIS PRODUCT.
