Digital camera reviews of Cobra CPI 1575 1500 Watt 12 Volt DC to 120 Volt AC Power Inverter
Digital camera Review: Cobra CPI 1575 ---- Don't buy.
Summary: 1 Stars
I bought CPI 1575 (new) and it had a very low power output. I exchanged it for another assuming I got a bad one. I decided to bench test this one before installing. The voltage on this one varied between 89 and 122 volts depending on load. Sent this back for a refund and ordered a Xantrex 1200. The Xantrex 1200 cost more but it works perfect. Luckily Amazon's return policy made the exchages very easy.Digital camera Review: Cobra CPI 1575 1500 watt inverter

Now that I worked my way through the confusion on the instruction sheet, I love this inverter. The confusion lays, not in the set up, but what happens after you get it set up. This is what happened. First , my bad, I did not have my ground installed correctly, I loosely wrapped it around the main ground, WRONG, you must firmly install it in the grounding screw on your 110V system. Second Although my batteries read 12.8 volts, I could see them dropping like a rock with only my laptop plugged in, something was wrong, I instantly shut it down and rechecked. The automated help line sucked. The Cobra people also moved their open hours on the Customer service line from 6:00pm to closing at 5:30 pm Central time. So I missed them too. I installed my ground correctly this time, I restarted my inverter and watched the volts fall in tenths, UNTIL it hit the magic number of 12.1 volts, then it stopped. YAY!!!!! , I plugged in a light and my computer and it very very slowly dropped voltage, I knew I finally had it. The booklet never said a word about this plunging voltage, so I was lucky I persisted and found out the it has a threshold where it drops too then stops and begins to work at 12.1 volts. SO yours might be a bit different than mine but CHECK THAT GROUND WIRE, because it not only drained my battery while the inverter was on, but it also drained it when it was OFF> and it's not supposed to do that. NOW it's working so much better and I am happier than a hog in a tater patch, GRINS, good luck folks. SKYDigital camera Review: Cobra Power Inverter

Product arrived under the specified delivery time. If mounting any distance from the battery, I would recomend using #2 gauge cable instead of the #4. This way you get no power drop to the unit and you can get full utilisation of the power needed. I would recomend this product.Digital camera Review: Cobra Power Inverter

I had bought this item to go camping with. I love the item, it does what it says on the box. I wouldn't use the inverter for long periods of time. You might fry out the altenator and, or battery. Unless you are installing it in a large vehicle.Digital camera Review: Could be Better

A friend of mine purchased this inverter (I'm sorry to say because of my recommendation) and I helped him install it in his travel trailer. The inverter is located 3 feet (wire length) from 3,new,100 amp-hr batteries wired in parallel. I used #4 gauge wire (the wire kit recommended which costs extra) for all connections between batteries and to the inverter. The first thing noticed when turned on was that the inverter showed about 200 watts of power being supplied when there was nothing connected to it. I then hooked up a 700 Watt coffee maker (resistive load) and the inverter indicated over 1500 Watts of power being supplied to it. It went into overload mode and shut down. The battery voltage under load at the time it shut down was 11.9 volts. Thinking that the coffee maker was maybe drawing more than the advertised amount of power, I hooked it to my 1000 Watt Honda generator (really 900 watts continuous). The generator had no problem running it. So I have to conclude that this inverter (1500W/3000W surge) is greatly over rated for its advertised power capabilities. About the only thing that is really handy is the remote on/off switch (extra). If you need anywhere near the full rated power, I'd advise buying another brand, even if if you have to pay more.
