I am an over the road truck driver and we bought a Cuisinart K-Cup coffe maker that draws 1500 watts of power and my 1500 watt inverter could not handle it. We installed this inverter and upgraded the inline fuses to 80 amps and it works like a charm. It can be a bit noisy under load but for the price I am VERY pleased. We have been using for three months so far.

I did my research, and looked over countless reviews. I bought the Whistler Pro-2000 watt power inverter, and I am VERY HAPPY!!! I am a trucker so I know what I am talking about when it comes to the needs of everyday power inverter use. I didn't want to have to use all 4 batteries to run a power inverter. I was using a Sima STP 1500 watt power inverter, and it always had problems running my 700 watt micro wave. I installed my Whistler Pro-2000 watt today and it worked just great. I am all smiles. My micro wave worked great without any problems. The digital read out told me how many watts I was using, and the 3 fans on the back kept it nice and cool. The old inverter would take 4 min. to cook a bag of popcorn, I guess because it wasn't supplying enough power. With my Whistler I was able to cook the same bag of popcorn in 2:30 min. and it almost burnt the popcorn, that is how well it performed. I will continue to update this review when I test it even further.

This is my first inverter so I have no point of reference to compare it to, but it's meeting my expectations in every way. Do read the reviews for this and other Whistler models as well as other inverters to avoid the mistake of thinking you can plug this into your cigarette lighter and you're done it ain't that simple! Please, please forget using your cigarette lighter with any inverter over 200W right now...you are almost certain to toast fuses or wiring in your car.
And oh yeah, a complete solution is not as cheap as this single item either.
My biggest complaint was about grounding the unit. There is a ground connector but not much detail about *how* to ground it or *why* to ground it in the manual. Searching around on the web I found posts suggesting that (1) you don't really need to ground it and indeed it works just fine without a ground wire, (2) if you don't ground it you will die, and (3) if you DO ground it you will die. I think I got that resolved (more later). My only other complaint is trivial: the supposedly always-powered USB port on mine is only powered when the switch is on. Not a huge deal.
I bought this to supply power to a few items in my house in the event of a sustained power grid failure caused by something like an ice storm or a hurricane, both of which I've experienced. I've had a gasoline generator for years but it took up lots of room, had to be maintained (oil/filter changes, keeping the tires inflated, exercising it periodically) and I had to remember to go buy lots and lots of flammable gasoline to store when the weather looked nasty (and provide space for all those gasoline containers). After reading a lot on the web I sold and replaced it with a solution consisting of...
* this Whistler 2000W inverter (up to 4000 starting watts you need to understand the difference between starting and running watts before you even think about buying an inverter or a generator!)
* two 12V 110 amp deep-cycle sealed AGM batteries to supply power to the inverter (you need to understand all those buzzwords too like deep-cycle, sealed and AGM)
* several not-too-cheap cables to connect the two 12V batteries together in parallel (a.k.a. a "battery bank"), then to connect them to the inverter (the inverter wants to be fed 200 amps; two 110 amp batteries in parallel provide 220 amps to make it happy; my car's alternator provides only 105 amps and yours probably doesn't provide much either, you need to understand parallel vs. serial battery banks)
* a "smart" charger to keep the two 12V batteries ready for use
* a few very robust extension cords
* a rolling utility cart to put all this heavy stuff on (the batteries are about 90 lbs. each)
* a ramp to let me roll the cart up two steps into the house from the garage
That got me started and that's almost all. This let me try to power the items I want to be able to run in an extended outage, including:
* my refrigerator/freezer, a recent model from Samsung that is very efficient, it starts and runs fine off the inverter
* as many CFL-equipped lamps as you'd like as well as a few electric fans they draw virtually no wattage; knock yourself out
* essential electronics including a laptop, cable modem, wireless router, NAS adapter, external hard drive, wireless printer, VOIP phone box, cordless phone base station, cell phone and tablet chargers but *not* the UPS that these are usually plugged into the UPS didn't like the inverter (I learned that a UPS *is* an inverter system with battery all in a box)
That left me with one essential item that wouldn't run: an older model, not very efficient portable/room-to-room air conditioner. It wanted more starting watts than the inverter could supply. Solution: do without the air conditioner or buy a newer, more efficient one. Still looking at that. I'll update this review when I figure out what I'm going to do.
One last problem: in an extended power grid failure, how do I recharge my battery bank when it has been depleted? I thought about cranking up the car and connecting jumper cables from its battery to the battery bank, but read too many posts online that made me uncertain about the wisdom and safety of that. Then the light bulb came on: another inverter, just a smaller one. My car's alternator will easily power a 400W inverter ($32, about the price of a good set of jumper cables). My "smart" charger only uses 150W. So for another $32, my car becomes a 400W 115V generator that runs the smart charger that replenishes the big inverter's battery bank. Problem solved. (Actually, I went for an 800W inverter for around $50 so that I could recharge the battery bank and still power some other items during the recharge my car's 105 amp alternator can handle the 800W inverter's 80 amp requirement with no problem. Your next assignment is to find out how many amps your car's alternator puts out.)
Confused yet? I was too and I'm still learning, but I think I've put together a pretty low-maintenance, high-reliability solution for a power failure lasting several days. I have around $1,000 in it and expect it to last for years. Just wanted to give a plug to this product while making people aware that there is a lot more to this than just buying an inverter.
Oh yeah, about grounding the inverter: that was easy. The ground lug is there to ground the inverter's case to the chassis of the inverter itself inside the case. Just connect an 18 or 16 gauge wire between the inverter's negative input terminal and the ground lug. I got this from Whistler tech support. I don't know why the unit can't just be supplied that way. Anyway, I've run it for hours with and without that ground wire and it works just fine. Like any electrical device, pay attention to what you're doing and be careful!
I have my cooking and heating needs covered for an extended period without electricity which is why they're not mentioned here.
Comments welcomed. Seems like I learn something new about this topic every day.
Honest reviews on Whistler Pro-2000W 2,000 Watt Power Inverter
I am an electrician and I bought this item for my boat.
In order for an inverter to work well it needs to have enough 12 Volt power coming to it. This means you should install the appropriate battery cables (in my case a pair of shorts #0 gauge was enough) and you must make sure your battery bank is big enough to provide the 200 Amps this inverter uses when in full power. My boat runs 2 alternators (110 and 55 amp) and 2 large car batteries in parallel dedicated for the inverter. In this sett up I was able to run 2020 continuous watts (1500W heater, 420W drill, 100W lamp) from the inverter for 15 minutes without a problem while the engine was running. However, when I attempted to run the same loads with the engine off, the inverter shutdown. There was nothing wrong with the inverter. The problem is that my battery bank is not strong enough to provide all the amps this inverter requires at full load. If you bought this inverter the best way to test if you have enough power arriving at the inverter is to gradually add a load while checking the display volt meter included in the inverter. The voltage should not dropp below 11.6 volts or the inverter will power off. After reading all the reviews on this product I've came to the conclusion that most unhappy customers likely had wrong/bad setups and that's the reason they are unhappy with this inverter. If in doubt about the proper installation, take it to an electrician. It will work, you will be happy and safe!

I bought this in case of another power outage tried it on my fridge and microwave and powered them up one at a time no problem ran them off a car battery it will keep you from losing all your things in your fridge and freezer so it might very well pay for it self the first time you use it it needs a fuse and cables which are not included I used a 200 amp fuse and 4 guage copper cables and mine works fine
