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 inverter can really put out the power. The low voltage alarm comes on at 11.3 Volts which is stated in the manual supplied with my unit. However, there are several online manuals which state the low voltage alarm signals at 10.5 V. Somewhere along the way they have updated the product and/or manual. I needed a wire length of 3 ft @ 4 GA to run 1200 watts off of a standby battery bank otherwise the low V alarms kicks in. Tested to 1500 watts and it will do it no problem. The fans never kicked in and the unit did not become even warm at 1200 watts for 10 minutes with an air temp of 25F. Longer run times would probably warm the unit up and turn on the fans.

The first unit I bought was suspicious from the beginning.
When the input voltage was 12V it complained that the voltage was too low and therefore it shutdown.
Needless to say, it failed a short while after.
I received a replacement unit from Amazon, and this one is working the way it should.
The inverter is a little sensitive on the low current side, but it works.
I love the digital voltage display.
The watt meter is not accurate at low power consumption, but gives a more realistic reading at higher power consumption levels.

Item is quiet and has low no load current draw. Mine was <.2 amp battery draw when on and 0 when off. Worked as advertized but you cannot measure AC voltage with a cheap meter as it will read 20-30 VAC low because of the modified sine wave. The documentation is barely adequate in that it doesn't answer the most common questions. One has to go on-line to the Cobra site. Also the Power out in watts doesn't indicate until you get over 100 watts and then only in multiples of 100 with the display showing only 2 digits ie: 10 =100 20 =200 etc. Documentation did not explain this or I would have given it 5 stars. Also it doesn't work on a small craftsman floresent shop light. It won't light the bulb. Only blinks. I suspect there are other limitations because of the modified sine wave but I am happy with the price for the quality. I choose it over the cheap harbour freight models that had poor reviews for about the same price. My next inverter will be a pure sine wave inverter as even though this one says 3000 watt peak, it will still not start larger than 1/2 HP motors that fall within its specs. The documentation does confirm this.

very efficient and quiet. i have used many inverters in the past but this brand is what i will buy from now on.other brands' fan starting to go right away contributing to drainage of your battery.the cobra cpi 1575 starts only when it needs to and i am yet to see it heat up for a need for the fans to come on.buy this model and you'll not be dissappointed.

I used this every day for a week at my remote cabin. I had loads that varied from 40 watts to 1750 watts. The inverter works great and the display is accurate.
