How long does the solar panel take to recharge the C400?

UDPOWER rates the 40W panel at 6 to 8 hours of charging in good sun, versus 12 or more hours for lower-efficiency panels. Cloud, shade and panel angle will stretch that.

Can the C400 run a mini fridge or CPAP?

The 256Wh capacity is modest. It is better suited to phones, laptops, lights and cameras; check the station's AC output rating against your appliance's draw before relying on it for a fridge or CPAP overnight.

Can it jump-start a car?

Yes. The kit includes a jumper cable and the station has a 12V port for jump-starting. Follow the manual's procedure and check your vehicle's requirements.

Is the solar panel waterproof?

The folding panel is rated IP65, so it handles rain splashes. The power station itself should be kept dry.

What comes in the box?

The C400 power station, the 40W foldable solar panel, an XT60-to-DC7909 solar charging cable, a car charging cable, a jumper cable and a user manual.

What warranty do you get?

Three years on the power station, 12 months on the solar panel, plus a 2-year after-service warranty and 24/7 U.S. support.

Our take on the UDPOWER C400 Portable Power Station with 40W Solar Panel

The UDPOWER C400 is a 256Wh portable power station bundled with a foldable 40W solar panel. The panel's monocrystalline cells recharge the station in roughly 6 to 8 hours of good sun, and the station covers USB-C PD, AC and 12V outputs, including a car jump-start cable. It suits campers and emergency-backup users who want a self-contained solar kit in one box. Against rival 250Wh-class stations, capacity and output are ordinary; the bundle's draw is the included panel and the long claimed battery and panel lifespan.
