Xantrex 851-0451 XPower 450 Portable Modified Sine Wave Inverter, 12V DC to 120V AC

Portable modified sine wave inverter for vehicles, RVs, boats, and mobile power use. Converts 12V DC battery power to 120V AC power for small electronics, compact TVs, laptops, lights, and other compatible AC loads.

About the Xantrex 851-0451 XPower 450 Inverter

The Xantrex 851-0451 XPower 450 is a compact portable inverter that converts 12V DC battery power into 120V AC power for compatible small appliances and electronics. It is designed for mobile use in vehicles, RVs, boats, vans, and work trucks where AC power is needed away from shore power.

The XPower 450 provides modified sine wave AC output and is commonly used for compact TVs, laptops, handheld electronics, compact fluorescent lights, soldering irons, and other compatible AC loads. It can be connected through a 12V lighter socket for lower-power use or connected directly to a battery when higher output is required.

⚡ 360W Continuous

Provides 360 watts of continuous AC output power

🔋 12V DC Input

Runs from a compatible 12V vehicle or battery system

🔌 Dual GFCI Outlets

Two GFCI-protected AC receptacles support multiple compatible loads

🛡️ Safety Protection

Includes overload, over-temperature, over-voltage, low-voltage, and short-circuit protections

Key Features & Benefits

  • Portable 12V Power Inverter: Converts 12V DC battery power into 120V AC power for compatible electronics and small appliances
  • 360 Watt Continuous Output: Provides 360W continuous AC output for supported loads

• Owner/installation documentation as supplied by manufacturer

📋 Use Notes

For lighter loads, the inverter may be used with a 12V lighter socket connection if the socket and vehicle circuit are rated for the load. Higher output use requires direct battery connection with properly sized wiring and fuse protection.

This is a modified sine wave inverter. Some sensitive electronics, battery chargers, medical devices, induction motors, variable-speed tools, and audio/video equipment may require a true sine wave inverter instead.

⚠️ Electrical Safety

Do not exceed the inverter’s output rating or the rating of the 12V socket/circuit being used. Overloading a 12V outlet, using undersized wiring, or operating with poor connections can cause overheating, blown fuses, equipment damage, or fire risk.

Use direct battery wiring and proper overcurrent protection for higher loads, and follow the manufacturer’s installation instructions.

Portable Inverter Use Checklist

Check Before Use Why It Matters
Load Wattage
This inverter provides 360W continuous output, 450W for up to 5 minutes, and 700W surge
Waveform Requirement
Modified sine wave output is not suitable for every device; some loads require true sine wave power
12V Socket Rating
Vehicle accessory sockets are often limited and may not support high inverter loads
Direct Battery Wiring
Higher output use should be wired directly to the battery with proper cable size and fuse protection
Battery Condition
Inverter runtime depends on battery size, charge level, and overall battery health
Ventilation
Inverters generate heat and need airflow to avoid over-temperature shutdown
Included Accessories
Some 851-0451 references describe an OEM/no-accessories version, so cable inclusion should be verified by seller inventory

The Xantrex 851-0451 XPower 450 is a portable modified sine wave inverter for 12V DC systems. It provides 360W continuous output, 450W for up to 5 minutes, and 700W surge output. Verify load wattage, waveform requirements, 12V circuit rating, wiring, fuse protection, and included accessories before ordering.
