Cobra CPI400PSW 400W Pure Sine Wave Power Inverter, 2 GFCI Outlets, USB-A & USB-C
Product Description
Overview
The Cobra CPI400PSW is a 400-watt (800W peak) pure sine wave inverter that converts 12V vehicle power into clean 120V AC. Pure sine output is safe for sensitive loads like CPAP machines, medical devices, and laptops that run noisily or fail on cheaper modified-sine inverters.
Two GFCI-protected outlets and fast-charge USB-A and USB-C ports let you run and charge at once, and roughly 90% efficiency draws less from your battery for longer runtimes.
