    This inverter was easy to install and it powers my 700 watt microwave like it's child's play. The installation is a bit time consuming though. I had to figure out where to mount it and run the wires. I chose to mount directly behind the passenger seat on the wall of the storage cabinet in the sleeper area, I used putty along the bottom of the inverter when I attached it with screws to prevent vibration from the road. The wires were able to be run behind the storage cabinet and then through the floor by removing a drain plug underneath the carpet. Must use extreme caution to protect the wire from rubbing bare against any metal or plastic to prevent a short/fire. I used zip ties and plenty of electrical tape. I'm not sure why Amazon indicates 2 wire install kits are required for the 2500 watt inverter, I used 1 wire kit and it works just fine. Just be sure to use a 250 amp fuse within a short distance of your power wire connection. I was able to get power near my A\C filter in the engine compartmentUPDATE June 2016:Apparently using just one set of wires wasn't a good idea after all. The unit worked fine for awhile until one day when I apparently had 1 too many appliances running at the same time. The power consumption was too large for one set of wires to handle and they burnt to a crisp. I wound up having to replace the wires and this time I used 2 wire sets and 2 fuses from the same battery source and the unit now works great, no more low voltage indicator noise coming from it. Live and learn.

    Seems to work well. It takes a lot of use for the fans to kick on. Unit will beep 4 times and flash OLP when turning on. And Kwh meter doesn't function on these. Watt meter doesn't work until you put a draw on it of about 6 to 8 amps. Must have four 4 gauge cables to get any real power out of this, mine are 18 inches. And boy does this thing drain batteries fast! I tested a 12 amp 1500 watt electric heater connected to 220 amp hour total on a pair of deep cycles and it hit the low voltage alarm in 15 seconds! You need some serious battery power to run this thing at full potential or hook it up to a car or truck. I would say you need at the least 6 to 8 120 amp hour deep cycles on a 800watt to 1kw solar setup to really get this thing to rock and roll

    I just used this in the aftermath of Hurricane Sandy. It worked well for me. I powered two refrigerators at about 200 watts each + about 150 watts of lights. (The fridges spike at 500 watts each when you first plug them in.)

    I followed the others' advice and got 4 gauge jumper cables. I cut them at 4 feet, peeled the casing to expose about 1 inch of wire and attached to the inverter. I just used the clamps to car battery. I only used 1 set of cables (but it has spaces for 2).

    I never had any issues. With the car running, it easily powered 1000w. With the car off, I could run about 600 watts for 20-30 minutes and the lights alone (140 watts) for 2-3 hours.

    The inverter was also fine for charging computers, phones, etc., but when I connected my TV, the TV started making noises so I disconnected right away to avoid any problems with the TV when the power came back.

    All in all, the unit was a bit of overkill for my use, but I would rather overdo it than be butting up against the wattage maximums.

    When I got this product, I was surprised it made a beep beep beep, then the fans shut off, and the display went between showing the voltage and the wattage being used currently. No matter how I hooked it up, even to a bank of 3 marine cranking batteries with no more than 15" long sections of wire connecting batteries together, and the same from the end battery to the inverter, it still made the beep beep beep, and then turned off (so I thought.)
    Anyways, I thought something was wrong with the inverter because of the weird behavior upon powering up. It turns out, after making the beep noises and stuff, which is actually a normal test it runs when it is powered on, that the inverter works just fine! It just doesn't need the fans on if there isn't much load. So, for those who think theirs may be bad, try plugging something in first, and it probably works. It just doesn't turn a cooling fan on, with a 13watt fluorescent trouble light plugged into it.
    As for my actual review of the product, it works great! Powers stuff up to at least 1600 or 1800 watts with no issues, even when just hooked up to a 2 farad capacitor, that is hooked up to my SUV's battery in front with 10feet of 4gauge cable going to each terminal on the 2 farad capacitor. (Then 1.5 feet of #4 cable going from the capacitor to the inverter on both terminals, along with #6 cable to my car audio amplifier.)
    The biggest thing is, make sure to use connectors, crimp on ends, battery terminals, etc., that are intended to be used with 4 gauge cable or bigger, so you do not bottle-neck your power before it gets to the inverter at some point. And yeah, it does need a lot of juice to continuously run things at higher levels of power (like 2.5kw, not 250watts.) You just need to do the math to be sure you can put out the juice you need, for as long as you need.

    Purchased this Cobra unit because the Eliminator from Canadian Tire does not have a short circuit fuse.
    Find out that the Cobra is like the Eliminator, no fuse, so if the + and - accidently touch, the unit is scrap.
    Other than that feature, the unit works good.
