PPS-P350L 288Wh LiFePO4 Portable Power Station Quiet CPAP Backup For Night Therapy

PPS-P350L 288Wh LiFePO4 Power Station for CPAP and Night Therapy

A CPAP machine that stops at 3 a.m. is not a minor inconvenience. The PPS-P350L is built around one job: keeping a therapy device, a phone and a bedside lamp alive from bedtime to morning without a generator, a fan or an exhaust.

Inside is a 288Wh LiFePO4 bank rated for 3,500 cycles, paired with a pure sine wave AC output of 350W continuous and 600W peak. Typical therapy devices draw between 30W and 60W, so the pack covers a full night with margin, and the 10 ms bypass mode means the machine can run while the station itself is on mains.

How a night is covered

Quiet by design

There is no fan on the main inverter stage at therapy loads, and the cell chemistry is LiFePO4 rather than a high-voltage NMC pack, so the unit stays stable in a warm bedroom. Noise at 1 m is below normal room ambience. The station can sit on a floor or under a nightstand without disturbing a partner.

Charging between nights

• Mains: 0 to 100 percent in about 1.6 hours from a 200W AC input.
• Solar: up to 240W through an MPPT input that accepts 12-35V panels, useful during long outages.
• Car: 12-15V at 8A from a vehicle socket during travel.

Ports at a glance

Two AC outlets (US and EU versions available), 140W USB-C PD for a tablet or laptop, 18W USB-C, 18W USB-A and a 12.8V 10A car socket for a small lamp or a heated travel blanket. The 140W PD port also recharges the station itself from a USB-C charger when no AC is nearby.

Safety and compliance

The pack is UN38.3 tested, carries CE, FCC, RoHS and PSE marks, and the BMS protects against over-charge, over-discharge, short circuit and over-temperature. The EPS transfer of 10 ms keeps a therapy device powered through a grid dip when the station is plugged into mains.

Questions buyers ask

Will it run my specific machine? Send us the wattage on the device label. Anything up to 350W continuous is within range.

Can it be used every night? Yes. LiFePO4 is rated for 3,500 cycles to 80 percent capacity, which is roughly ten years of daily use.

How is it shipped? One piece per SOUOP colour box with foam inserts, 7-15 working days after payment, T/T, L/C, PayPal or Western Union.
