Powerful 1,500-Watt AC Output

The Cobra PRO 1500W provides a convenient source of AC electricity when a conventional household outlet is unavailable. With 1,500 watts of continuous output, the inverter can operate a variety of compatible electrical devices from a properly connected 12V battery system. The 3,000-watt peak rating accommodates brief startup surges from certain compatible appliances. Common applications include:

• Laptop computers and power adapters
• Smartphones and tablet chargers
• Portable monitors and entertainment equipment
• Camera and photography accessories
• Small kitchen appliances
• Mobile office equipment
• Battery chargers and compatible power tools
• Camping and recreational electronics
• Other devices within the inverter’s electrical ratings

The total power consumption of all connected equipment must remain within the inverter’s continuous output rating. Some appliances require substantial startup power or pure sine wave electricity and may not operate correctly with this inverter.

Four GFCI-Protected AC Outlets

The Cobra CPI1500W features four grounded 115V AC outlets, providing convenient connections for multiple devices. Each outlet is part of a GFCI-protected system designed to interrupt power under certain ground-fault conditions. This configuration allows users to connect several compatible electronics without relying on additional outlet adapters. The four outlets share the inverter’s total available power capacity. Connecting multiple devices does not increase the maximum 1,500-watt continuous output. The grounded outlet design makes the inverter practical for mobile offices, recreational vehicles, camping equipment, and other applications requiring multiple electrical connections.

USB-A and USB-C Fast Charging

In addition to its four AC outlets, the Cobra PRO 1500W includes dedicated USB charging ports for portable electronics. USB-A Fast Charge Port Provides up to 15 watts of charging output using supported 5V and 9V charging profiles. USB-C Fast Charge Port Offers up to 15 watts of charging power for compatible USB-C devices. These connections are useful for charging:

• Smartphones
• Tablets with compatible charging requirements
• Wireless headphones
• Bluetooth accessories
• Portable electronics
• Other compatible USB-powered devices

Charging speed depends on device compatibility, cable quality, and supported charging standards. The USB-C port is not intended to replace high-wattage USB-C laptop chargers.

Modified Sine Wave Power Technology

The Cobra PRO 1500W uses modified sine wave technology to convert battery power into alternating current. This design provides an efficient and practical solution for operating many compatible electronic devices. With a power conversion efficiency rating of up to 90%, the inverter is designed to reduce electrical losses while providing usable AC output. However, modified sine wave electricity differs from the pure sine wave power normally supplied by household electrical systems. Certain sensitive electronics, motor-driven appliances, medical equipment, and specialized power supplies may require pure sine wave output. Always verify device compatibility before connecting equipment.

Integrated Digital Power Display

The Cobra CPI1500W includes a digital LED display that helps users monitor operating conditions. The display provides useful information about the inverter’s performance and connected battery system. Available information includes:

• Input battery voltage
• AC output power in watts
• Output power in kilowatts
• Operating indicators
• Diagnostic error codes

This makes it easier to monitor electrical demand and identify potential operating problems. The display is particularly useful when several devices are connected and total power consumption needs to be monitored.

Advanced Pentagon Protection System

The Cobra PRO 1500W incorporates multiple electrical protection features designed to support reliable operation. Its integrated protective systems help reduce the risk of damage caused by abnormal electrical conditions.

• Overload Protection: Helps protect the inverter when connected equipment exceeds the rated power capacity.
• Overtemperature Protection: Automatically interrupts operation when excessive internal temperatures are detected.
• Short-Circuit Protection: Helps protect against certain electrical short-circuit conditions.
• Reverse Polarity Protection: Provides protection against incorrect battery polarity connections.
• Overvoltage Protection: Helps prevent operation when input voltage becomes excessive.
• Low-Voltage Alarm: Warns users when the connected battery voltage drops below the configured threshold.
• Low-Voltage Shutdown: Automatically stops operation when battery voltage falls below the permitted operating range.
• GFCI Protection: Provides additional ground-fault protection through the AC outlets.

These safety features complement proper installation and electrical precautions.

Automatic Cooling System

The Cobra PRO 1500W features dual temperature-controlled cooling fans designed to maintain appropriate internal operating temperatures. The fans activate when additional cooling is required and stop when temperatures return to the appropriate range. This helps reduce unnecessary fan operation during lighter electrical loads. For reliable performance, the inverter should be installed in a dry, well-ventilated location with sufficient clearance around its cooling openings. Avoid placing the inverter near heat sources or inside sealed compartments without adequate ventilation.

Optional Remote Controller Compatibility

The Cobra CPI1500W includes a dedicated connection for the optional Cobra CPIALCDG1 remote on/off controller. The compatible remote accessory allows users to manage inverter operation from a more convenient location. This is particularly useful when the inverter is installed in an RV storage compartment, vehicle equipment area, or other location that is not easily accessible. The compatible remote controller also provides additional monitoring and charging functionality. The CPIALCDG1 remote controller is sold separately and is not included in the standard inverter package.

Ideal for RVs and Mobile Work Environments

The Cobra PRO 1500W is designed for applications requiring dependable portable AC electricity. Its combination of multiple outlets, USB charging, and substantial continuous power makes it suitable for many different environments. Common applications include:

• Recreational vehicles and campers
• Commercial trucks and work vehicles
• Road trips and long-distance travel
• Camping and outdoor recreation
• Mobile office installations
• Photography and video production
• Tailgating and outdoor events
• Compatible marine battery systems
• Emergency preparedness
• Vehicle-based electronic equipment

The inverter provides a convenient solution for users who need access to compatible household-style electrical connections while away from conventional AC outlets.

Direct Battery Connection

The Cobra CPI1500W is designed to connect directly to a compatible 12V DC battery system. Unlike smaller automotive inverters, a 1,500-watt unit requires a substantial amount of electrical current during high-power operation. For this reason, proper battery capacity, cable sizing, overcurrent protection, and installation are essential. The included power cables are designed for battery connection, while the inverter’s positive and negative terminals provide the required electrical connections. Professional installation is recommended when users are unfamiliar with high-current 12V electrical systems. The inverter does not include an internal battery and cannot provide electricity without a suitable external DC power source.

Included Accessories
