Beware of all those talking about failures of the inverter - one guy says that he returned his, because two 70Ah batteries couldn't power it to run a 1/2 horsepower motor.

Well...guys, there are a few things you need to know about inverters before buying a big one...which does NOT directly substitute for a generator! The little ones are WAY DIFFERENT than the big ones.

First off, at 2500-watts, you are pulling 200+ amps across the wire...so, unless you are hard-wired with some 4/0 solid-strand wire, you really need to go with DOUBLE 4-AWG strand wires...basically, buy TWO sets of 4-AWG jumper cables, and after you cut the ends off both, then run double-strand (both red AND black) of a complete set to EACH POST of the inverter...yes guys, that's a LOT of wire...and due to heat, I wouldn't run that more than 5-6 feet!

Now...batteries...let's laugh at the guy trying to get 1600 watts of batteries to run a 2500 watt inverter...and consider what you REALLY NEED...for deep cycle batteries rated on the 20-Ah system, and rated at, say 500-Amps, then buy 6 of these and wire them in PARALLEL circuit to power the inverter. Yep...$600 in deep cycle batteries! Now, you have enough batteries to power the inverter for 2-6 hours, depending on loading, before you will need to recharge your 6-battery bank. Plan on a charger that can throw 50-100 amps into the charge...so your little $50 Schumacher charger is NOT going to charge this battery bank overnight! Try more like a $300 charger to charge them in 12-hours...or, if you want solar, good...you need to throw about 70-amps of charge into these for 12-hours solid...so that is $300-$500 in solar panels. Also note...batteries get weak after enough cycles...so pay attention to your charge circuit...

To all the people who have issues in getting full or high wattage out of this or any other unit: you MUST have thick (#4) and short (3-4ft) 12v cables to your battery bank. Otherwise the inverter will be starved for current and cause the "low voltage protection" to kick in. Make sure your battery/ bank are up to the task as well.

This unit works great for me. I tested it with combination's of differing equipment (electric chainsaw, power saw, A/C unit, refrigerator, electric heating unit). No problems for me. Do your homework before giving out 1 star reviews people...

We have alot of experience with inverters, and this inverter is just average. It does produce quite a bit of power, but we seem unable to run both of our energy efficient freezers simulatneously (about 1.7 amps draw each freezer --200watts). Also, it does not come with cables to attach it to the batteries, so expect to buy those too. Lastly, and most importantly is the noise. The inverter cooling fan starts up at even the smallest load, and it is loud. As more load is applied the cooling fan ramps up louder and louder. It is not so loud as to hurt your ears, but it is loud enough to be annoying and to heard throughout whatever room it is in, so I recommend you buy the remote start if you choose to buy this unit. Locate it in a closet or shed so you don't have to listen to it.
We have had other inverters that cost much less, but of course only 1200 Watts of power, that had NONE of the shortcomings of this one (our old 1200 Watt model simultaneously ran both freezers, T.V. VCR, DVD player, speakers, and lights; it came with a connector cable, and its fan was quiet and only came on during high loads). The reason we purchased this one is because all the previous inverters, although quiet and efficient, eventually died, and we hoped that this one could handle the peak loads better.

9 April 2009: Just a brief update. At this point in time the inverter is useless, the cooling fans quit working so I am hesitant to use if for fear of a fire (that happened with another inverter several years ago). To be fair, we used that inverter nearly every day at times for up to 12 hours straight. But it never did meet our expectations, and now we are looking for replacement.

i have recently purchased the inverter 2575 by cobra. i installed it into my car and it runds great. i found the inverter to be smaller than expected and was able to install it into the dash of my car.

The instructions for the inverter are clear and precise, however i am still unsure it i can run it with the engine on. I also used the cables that were recommended 4000W for around $30.00 it was by far the cheapest around. Be careful when installing the inverter, i took almost the entire 10feet to get from the battery to the dash via the left hand front guard.

from an earlier "feedback" they said the inverter made quite abit of noise, i mesured it at around 55Db from one foot. which isn't all that loud but if you were running a fridge all the time and the inverter was close to you it would get annoying. I use it for a 800W microwave, it has plenty of power left o could run a tv and Wii system at the same time.

I recommend it for the price ($200.00)i felt it was a bargin, and they have a support phone number if you get stuck. having it for my ipod is also great.
