How The Cobra Power Inverter Works
The Cobra power inverter is an electronic product that has been designed and built to take low-voltage DC (Direct Current) power from your automobile or other low-voltage power supplies and convert it to standard 115 volt AC (Alternating Current) power like the current you have in your home. This conversion process thereby allows you to use many of your household appliances and electronic products in automobiles, RVs, boats, tractors, trucks, and virtually anywhere else.

Cobra 1500 Watt Output Waveform
Some very sensitive electronic equipment might not operate satisfactorily on "square wave" or "modified sine wave" power. The output waveform of the Cobra Inverter is a "square wave" or "modified sine wave." It is a stepped waveform designed to have characteristics similar to the sine wave shape of utility power. A waveform of this nature is suitable for most AC loads, including linear and switching power suppliers used in electronic equipment, transformers, and motors.

AC receptacles
With three ground AC receptacles, you can connect and power multiple devices at once.

USB Output
The 5-Volt USB output allows charging and operation of modern portable devices, such as iPods, BlackBerrys, and cell phones.

Remote On/Off Switch Capable
An optional Remote On/Off Switch can be connected to the Remote Jack, allowing you to turn the Cobra power inverter on or off from a convenient location when the inverter is installed out of reach.

Safety Features
The CPI 1575 will notify you with a flashing meter and alarm sound when there is a power problem, and will shut down for protection in the following situations:

  • Current Overload Protection--If the inverter is overloaded, it will shut down to protect itself.
  • Short Circuit Protection--If the AC output of the inverter is short-circuited for one second or more, it will shut down to protect itself.
  • Low Voltage Protection--If the input voltage drops to 10.0V or less, the inverter will shut down to protect itself.
  • High Voltage Protection--If the DC input voltage rises above 15.0V, the inverter will shut down to protect itself.
  • Over Temperature Protection--If the internal temperature rises to 40 degrees C (104 degrees F), the inverter will shut down to protect itself.

This review is in response to some comments regarding wire and fuse size selections for this inverter and others like it.

In response to other review quoting a table from the National Electric Code (NEC). While the table that was posted is correct for 115VAC (household voltage) is does not translate directly to 12VDC (automotive voltage). When dealing with a 12 volt system there is less concern with wires overheating, at least in the way that the NEC considers it, and far more concern with voltage drop. When running wiring a reasonable distance (a couple hundred feet or so) there is little concern with voltage drop with AC power. But when dealing with DC, simply increasing your wiring distance 5-10' can have a drastic effect on voltage drop. That is why this inverter should be wired with, at the very least, #4 wire and really should be installed with #2 or thicker, especially if you need to run wire 15 or 20 feet or more.

The purpose of a fuse in a DC system is to protect the rest of your electrical system in the event of a short. That is why you always want to install your fuse as close to the battery as possible (no more then 3' if you can help it). As far as the amperage goes, there is a really good quick reference chart for automotive wire size that can be found at Tessco's web site here:[Turns out I can't link to an outside page so I'll paste the contents of the table at the bottom]. But to boil it down, you can safely fuse a 12VDC circuit at 150, or 200 amps, or more on #4, #2 or #0 wire.

Now this unit at full load is something like 85% efficient. So if you do the math -- 1500 Watts / 12 Volts / .85 efficiency = ~147 amps, A 150 AMP FUSE IS REQUIRED.

This product works great, I have a microwave, flatscreen tv, and a toaster i hook up to it and there is no problems. One thing I wish would have been mentioned somewhere is that you need to purchase a 150 amp inline fuse to put in the power wire from the battery to the inverter. So plan on getting one of those and have it ready so you can install it. I didnt know about it and spent some time in North Dakota trying to find one. Enjoy.

Other reviewers don't seem to have had the problem I did, so this might be a good product but I must tell you my experience with it. I am very familiar with inverters and how to hook them up having lived off of solar power now for over ten years. When I first set up this inverter, the input voltage showed 12.3 volts, the same as my battery voltage but undr a 110 watt load the output wattage meter showed 0 (zero) watts. What I had plugged into the inverter was working fine (a small TV), so I assumed this meter was just broken. If that was all that was wrong I could have lived with it. The next morning I turned it on, turned on the same TV and within 20 minutes the picture on my TV slowly shrank down to a pinpoint and then shut off. There were no low voltage warning sounds. I checked my battery level and it was at 12.2 volts, the same 12.2 volts showed on the input meter on the inverter, output still showed zero, as it always did. I checked the output at all three of the outlets on the inverter and they showed zero. I turned the inverter off and then back on with the voltage meter still in one of the outlets and watched my meter go from 119 volts down to 30 volts, up to 80 volts and then back to zero. The whole time there were no warning sounds coming from the inverter. This fluctuation could very easily damage anything that was plugged into the inverter!!!!

The good news, Amazon's return system is very easy, didn't cost a penny to return it and I got a refund quickly. I thought of getting a replacement instead of a refund because of all the good reviews but decided not to press my luck, no equipment was damaged this time but why risk it again. If I could rate Amazon I would give them five stars but the inverter gets zero xtars since it didn't function as advertised, went dead under much lower load than it is rated for.

The inverter is working for me exactly as described and as I hoped. I drive a truck and have it installed to replace an older, smaller model. I run a number of things including my laptop, external speakers, printer, TV and a coffee pot. The low input warning works great, and will shut down the inverter if necessary. I will be adding things soon, such as a microwave.
The meter is a great feature which lets me see how much power is being drawn by each device attached as well as the input voltage.
I highly recommend this inverter.

I decided to try this product out because it was the only one reviewed extensively and was fairly inexpensive. Well I now know why. Before I begin I would like to state that Amazon is amazing. Throughout this entire ordeal they overnighted the products to me. "COBRA AND THE CHEAP CHINESE CRAP BEING SENT OVER" are the ones to blame for this problem. I have had to return three of these and have since switched products. The first one I received the USB port didn't work so I sent it back. Received the second one two days later (Amazon being great) the voltage output was 95 way below the +- 10% of 120 allowed, and as stated elsewhere the wattage indicator didn't work. Sent the second one back and received it two days later (Amazon again) and tested the voltage this one output 85 volts which is completely unacceptable, and to top it off the wattage indicator still didn't work. I don't know about other reviewers but if something doesn't work (wattage indicator) I'm not happy. I pay good money for this piece of crap and I expect it to work. Amazon is now giving me a refund and I am purchasing a PowerDrive 1500, because it has been recommended to me by Truckers and is sold at most truck stops. Cobra has no quality control and nobody expects anything good from China. Stay away from this product it will give you nothing but headaches and it still won't work. Keep buying from Amazon though.
