The PGYOB P400 is a 400W portable power station with a 296Wh LiFePO4 battery, two pure sine wave AC outlets, and a 65W USB-C PD port that can also recharge it in about 3 hours. It weighs 7.3 lb and runs quietly, so it suits CPAP users, campers and small-outage backup. Its LiFePO4 cells last far more cycles than the older lithium-ion packs common at this capacity, but 296Wh is modest next to 500Wh-class rivals, so it runs small devices and short appliance bursts rather than fridges or heaters.

Rated 4.2 out of 5 across 124 ratings, buyers mostly like the quiet operation, the fast USB-C recharging and the CPAP-friendly output. Complaints center on the modest capacity and on the separate solar panel.
This portable power station has a 296Wh LiFePO4 battery and two 110V pure sine wave AC outlets rated at 400W, with an 800W peak. It has 11 outputs and 2 inputs, and it can charge up to 6 devices at once. It is CPAP compatible and runs under 30 decibels.
It can power or charge smartphones, MagSafe devices, MacBooks, laptops, cameras, drones, blenders, mini coolers, air pumps, TVs, electric blankets and small household appliances. The USB-C PD 65W port works as both input and output, and the unit can fully recharge in about 3 hours. It has a solid carry handle. A solar panel is optional and not included.
Estimated run time is 296Wh x 0.85 divided by your device's wattage. The 0.85 is the conversion rate, and actual run time varies with conditions. Turn off all output ports when not in use. The unit shuts down automatically about 3 to 5 seconds after the last output is off.
