About the Cobra Power 500W

Dave Delamere

Safe and reliable power from your vehicle

You want to use your household AC-powered devices in your vehicle, but cars, vans, and trucks use DC power. Cobra's Power Series power inverters safely convert your vehicle's DC power to AC power, allowing you to run your household devices from your vehicle power supply — perfect for tailgating, camping, and light-duty work sites.

Safe and reliable power from your vehicle

You want to use your household AC-powered devices in your vehicle, but cars, vans, and trucks use DC power. Cobra's Power Series power inverters safely convert your vehicle's DC power to AC power, allowing you to run your household devices from your vehicle power supply — perfect for tailgating, camping, and light-duty work sites.

500 watts of continuous AC power

The rugged Power 500W inverter draws power from your vehicle's battery, then delivers up to 500 watts of continuous AC power to two Ground Fault Circuit Interrupter-protected (GFCI) 3-prong AC outlets, so you can run your tablet, laptop, video game console, power tool battery charger, and many other devices. This inverter also has two USB power ports, so you can charge or run devices that don't require an AC connection, like a smartphone.

Cobra Power 500W DC-to-AC power inverter

Cobra provides a way to access power from your vehicle for those "have-to-have" devices while on the road.

Connections and placement

You can plug the Power 500W into your vehicle's 12-volt power port using its 16" cord, or you can use the clamps on its interchangeable 16" power and ground cables to connect the inverter directly to your vehicle's battery terminals. Mounting tabs on either side of the chassis let you secure the Power 500W in place for a permanent charging station in your vehicle.* For added convenience, this inverter is compatible with Cobra's optional Remote On/Off Controller that includes built-in Fast-Charging USB ports and lets you tuck the inverter out of sight.

Safe power for your gear

Cobra's Pentagon Protection® safety features include over-temperature, reverse polarity, and overload protection, plus high/low voltage shutoff — designed to protect your connected devices and your vehicle's electrical system. This inverter's high-speed fan also keeps it cool.

*Note: Cobra advises not to permanently install the inverter in your vehicle's engine compartment.

Features

500 Watt Power Inverter: The Cobra POWER 500W (CPI500W) power inverter can provide up to 500 watts of continuous AC power, with a high-surge capacity of up to 1000 watts, from a connected 12V electrical system. Outputting a 90% efficient modified sine wave, the power inverter can provide longer run times for your connected devices while extending your vehicle battery life. The POWER 500W features two GFCI AC outlets along with USB-A and USB-C Fast Charge ports for charging portable devices.

Note: The Cobra POWER 500W is designed to work with 12V batteries and is not compatible with 6V or 24V electrical systems.

Applications: The POWER 500W power inverter is perfect for providing power for a multitude of devices such as fans, tools, entertainment devices, small appliances and LCD TVs, and more.

12V Power Port or Battery Power: The Cobra POWER 500W has the option to plug into your vehicle's 12-volt lighter/power port or connect directly to your vehicle battery for power. It includes a 16" lighter/power socket cable, along with 16" power/ground cables to connect directly to the battery via attached clamps. Both sets of cables are terminated in ring-terminals for connection to the inverter. The POWER 500W can operate on DC input voltage from 10-15 V.

AC & USB Power: The POWER 500W features two GFCI protected AC outlets and two USB power ports.

  • DC Input Voltage Range: 10-15 VDC
  • Output Voltage (Nominal): 115 VAC, 60 Hz, 4.3A, 500 W (maximum)
  • USB Outputs:
    • USB-A: 5V/3A, 9V/1.67A (Fast Charge)
    • USB-C: 5V/3A, 9V/1.67A (Fast Charge)

Notes:

  • Some chargers for small nickel cadmium batteries can be damaged if connected to the Cobra POWER 500W inverter, including small flashlights, razors, and night lights that can plug directly into an AC outlet. This also includes some chargers for hand power tool battery packs that warn of dangerous voltages present at the terminals.
  • The Cobra POWER 500W outputs a "modified sine wave" (stepped waveform) that's suitable for most AC loads including linear and switching power supplies used in most electronic equipment, transformers and motors. However, some very sensitive electronics and medical equipment may not operate properly on a modified sine wave. In these cases, the Cobra PURE SINE 400W may be an ideal alternative.

Battery Operating Time: The operating time of your connected equipment will vary depending on the charge level of the vehicle battery, its capacity and power level drawn by the particular AC load. Care should be taken to calculate the total amperage draw of your connected equipment in order to determine the amp-hour rating for the battery (how long the equipment can run without draining the battery). The POWER 500W user manual provides step-by-step instructions for calculating the amp-hours, including the Starting Load surge. When using a vehicle battery as a power source, it's recommended to start the vehicle every 1-2 hours to recharge the battery before its capacity drops too low. A low-voltage alarm will let you know when the battery drops to approximately 10.5 V and will cut off power consumption completely at 9.5 V.

Optional Remote Controller: The Cobra POWER 500W can be remotely controlled using the optional Cobra Remote Controller (sold separately). The Remote Controller connects to the POWER 500W's RJ-45 socket using the 15' cable that's included with the remote. It can then be mounted in a convenient location, letting you power the inverter on/off remotely. A 2-line LCD on the remote will display an error message if a problem with the inverter should arise, and USB-A and USB-C ports provide convenient device charging.

Power Switch & Indicator: The inverter includes an On/Off switch and Power LED to indicate when the unit is active. The Power LED will light Green under normal conditions and light Red if a fault arises.

Fan Cooled: A built-in high-speed cooling fan helps protect the inverter from over-heating.

Pentagon Protection & Safety Shut-Off: The Cobra POWER 500W inverter provides 5 levels of protection and will shut down and/or sound an audible alarm if it detects one of the following: Over-Temperature, Reverse Polarity, Over-Voltage, Low-Voltage Alarm, and Low-Voltage Cutoff. The inverter can provide 500 watts for approximately 60 minutes before needing to cool down. A 15 minute cool-down will be required to resume operation at 500 watts.
