The Cobra CPI 200 CH car power inverter has a fantastic design that fits into a cup holder. The construction is original and the cup holder provides an extremely useful location to store the portable inverter. The power inverter has a continuous power capacity of 200 watts. This is a perfect fit for most cars, and the combination of high-voltage, sleek design and full feature set help this unit stand out from the competition. The Cobra car power inverter is our Top Ten Reviews Silver Award. However, unlike the higher-ranked power inverter, the Cobra model only has one AC outlet.

The average car only supports 15 volts when using a power inverter connected to the cigarette lighter. This means that inverters can only support up to 150 watts. This amount of power will support most household electronic devices you could use on a road trip. Some of the devices that are compatible with the Cobra car power inverters are

  • Laptops
  • Cell phones
  • TVs
  • Gaming consoles
  • DVD players

The Cobra 200-watt car power inverters operate best at less than 90 percent capacity of the total wattage. This means that it operates best at the power range supported by the car’s cigarette lighter.

The Cobra car power inverters have an AC outlet and a USB port. You can use the USB port to connect cell phones or any other digital equipment that charges with a USB connection, such as an MP3 player. The Cobra power inverter only has one AC outlet, which means you cannot simultaneously power multiple devices that require a standard outlet.

The power inverter has multiple integrated safety features. One of those features is an overload protector. When there is a power surge or the device draws too much power, it will shut down before the portable inverter is harmed. This does not harm the device, and it's safe to test appliances and devices on the unit. The inverter also has a feature to protect against overheating. If the internal temperature of the car power inverter exceeds 104 degrees Fahrenheit, the inverter will automatically shut down. This safety feature is often called a thermal cutoff. To help protect from overheating, the unit has a fan that will constantly be blowing. The sound of the fan is minimal and not too distracting.

The unit also has a couple of different battery-life protections. If you are using the inverter without the car engine running, the inverter can drain the power from your car battery. However, the Cobra car alarm has an alarm that will sound when the input voltage coming from the car battery drops below 10.5 volts. This is an audible beeping noise that will alert you of the danger, but it will not turn off the car. When the voltage input drops below 10 volts, the inverter will automatically stop working. When this does happen, fix the voltage issue by starting your car engine and letting it run for about 10 minutes. This feature is extremely useful when you’re using your power inverter without starting the car. However, you won’t need to worry about this interference if you are only using the inverter while driving. The manufacturer recommends starting your car about once an hour and letting the engine run for about 10 minutes, if you are not going to constantly have the car running.

A true sine wave is constant energy flow. There are no interruptions in power supply. However, car power inverters with a true sine wave are extremely expensive. The Cobra car power inverters we reviewed utilize a modified sine wave. The modified sine wave can be thought of as a nearly continuous flow of power. There are some occasional stops in power. We didn’t notice any significant problems with the modified sine wave devices, even when watching movies and charging cell phones, but there is a possibility of power interruption. However, some battery chargers do not work well with modified sine wave power sources. We suggest checking the user manuals of the electronic device before charging. The modified sine waves can cause the charging units to overheat. We especially caution against using the modified sine waves to charge power tools.


The power inverter is expertly designed. It is in the shape of a coffee mug, with the AC outlet and USB port on the front of the unit. This means you can conveniently position the power inverter in a cup holder. The fan sucks air in from the top of the unit, so it's important to keep it totally clear of all debris and obstructions.

The buttons and outlets are all clearly labeled and easy to see. Using this power inverter is very easy and requires no training. However, for any questions or for detailed safety information, consult the user manual provided by the manufacturer.

The Cobra CPI 200 CH car power inverters stand out from the competition because of its innovative and useful design. However, the power inverter does not sacrifice substance for style and it has a high power capacity and a USB port. The customer service options offered by the manufacturer are also very useful.
