Got this to put in my little RV. I was looking for something small enough to not draw down
the one battery I have in the Coach. Installed under a cabinet close to the battery and
ran 10 ga wire to it. Plug in the Coach electrical cord to it and turned it on. It will
run a Radio or TV or the Microwave or the Fan in my A/C but not the A/C itself which would
take about a 3000 watt inverter which would drain my battery really fast! I watched TV and
listened to the radio for 2 days and finally ran the battery down running the A/C fan on the
second day. It's a little workhorse. Good for the price too!

The first one died within about 6 weeks. That is not a good sign... but Cobra made good and sent me a new one which has been working flawlessly for > year. I like this unit because the fan is active, not passive. So if you are using it to, say, charge a phone or run a laptop with a charged battery, (e.g. not much current draw) the fan stays off. As a noise-freak, that makes me happy. The power rating seems realistic, unlike two other units I tried. I'm quite happy with it, minus the dead original of course.

Bought this for tailgating at Buffet. I was actually able to hook it up to a lawn tractor battery and power a blender. I wasn't sure if the battery would have enough juice, but it worked great and was much easier to transport than a car or marine battery. Testing at home showed the low voltage alarms and whatnot work very well. I just wish this came with a cigarette lighter cord for those times you're just using it on low-amp devices the way some other inverters do. Also, I agree with some other reviews that the mounting tab locations look like they would make getting the screws in there difficult. I haven't tried mounting it, but the edges of the case definitely would get in the way. Creative DIYers would find a way to make it work, so no big deal.

I do NOT have electricity in my Carport, so this little gadget is a GODSEND. It runs my Elipitical Buffer (for my Cars) wonderfully, and cuts out BEFORE my Cars' Battery Charge is emptied. I would not want to be without it!

Used the Cobra CPI 880 800 watt inverter connected to a small solar/battery setup on a shed with no power.It runs a light, small radio,police scanner and a dremel pretty flawlessly. Of course I used a power strip but the inverter did fine. Like previous reviews stated its a little tough to mount this unit because the unit partially blocks the base. But just used some bolt head wood screws versus phillips head. open end wrench tightened them right down to the base. Used 0 gauge battery wire on run from battery. No complaints.

Mounted on my boat. I noticed that some has issue with the mounting brackets. This is probbly from those with little 'handy man' type experiances. All you do is mark your screw holes and then screw in one side. Then put the screws in the other side at an angle. Easy peasy.

The cooling fan only runs when it is needed, which is nice. Good value for the money. I'm using it to power a 750w blower (to inflate ski tubes etc) and it works great. Note: don't ever mount these in your boat enginge compartment (or you may go BOOM).

These units need too much juice to plug into a 12v cig lighter style, you need a direct connection to the battery with 2gauge wire. The included cords are fine, and have the clips to directly attach to a car battery

Had this for some time now never let me down it's got over load shut off and 1600 watt peak power so can power almost any thing I want and if I power so much stuff it shuts it's self off so I don't mess it up

mine works great. i don't use the wires that it comes with. they are short and thin. i modified my old jumper cables to use with it. i cut the clamps off of one end and permanently attached that to the inverter. now i have big clamps with 12 foot wires for a little more flexibility. i have used it for camping to make coffee and it worked great. i have also hooked up various power tools and those fired right up. (power drill, circ saw). i had my truck running while i was using it only because i was nervous about killing my battery. (we camp out in the middle of nowhere). it's a good little tool, i would recommend it.

I've had this unit in my car for a few weeks now. It powers two laptops just fine on road trips. However, the fan is constantly winding up even though it's in a well ventilated area.

This works great. Hooked it up to the clamps of my portable jump starter (just to test it out) and it ran a box fan high. Than I tried my desktop which is a gaming computer I built. Q6600 quad core overclocked to 3.4ghz 3x500gb raid 0 and 2x1.5tb hard drives. Geforce 8800 superclocked. Its 4 years old give me a break. It ran my desktop from start up to gaming and it was also running my monitor too. After 10 min or so the low voltage alarm came on but remember I was testing it with a portable jumpstarter that wasn't even fully charged. All in all its great. Its sitting in my car next to my amp so I can connect it to my amps power connection when I need to run something big.
