Compact Pure Sine Inverter for Mobile Power

The Samlex PST-120-12 converts 12 Volts DC into 120 watts of pure sine-wave AC power at 120 Volts and 60 Hz. Its slim, low-profile chassis includes a temperature-controlled fan for quiet operation and a USB charging port rated at 5V, 500mA. The unit ships with a 12V cigar plug adapter for immediate use.

120 Watt Continuous Output Decides Suitability

This inverter delivers 120 watts of continuous pure sine-wave power with high output current surge capability. The 0.5 Amp idle draw preserves battery capacity during standby, while overload protection and low-battery alarm with automatic shut-down protect connected equipment and the source battery.

Suited for Light Loads in Vehicles and Field Work

Service vehicles, boats, RVs, mobile offices and solar backup systems running small electronics such as laptops, printers, TVs or medical devices needing UL60601 compliance will find this inverter appropriate. Buyers who need more continuous wattage for appliances like microwaves or power tools should look at higher-capacity models.
