Portable power station 300W 237Wh
The WUQ M823 is a compact portable power station rated at 300 watts continuous output with a 375 watt peak. It stores 237 watt-hours of energy in a lithium battery pack. The cuboid housing measures 8.15 by 5.83 by 3.90 inches and weighs 4.6 pounds with a built-in carry handle. It suits campers, road-trippers and anyone needing backup power for small devices during outages.
Multi-output charging and LED lantern
Two AC outlets deliver 110 volt pure sine wave power for laptops, CPAP machines and similar loads. Two USB-A ports support Quick Charge 3.0 at up to 18 watts, two standard USB-A ports supply 5 volts at 2.1 amps, and one USB-C port provides Power Delivery up to 18 watts. A 12 to 16.8 volt DC port handles up to 10 amps continuous. Integrated LED lights on the top and side offer multiple brightness levels and SOS modes for campsite illumination.
Capacity and recharging limits
The 237 watt-hour capacity runs a typical CPAP unit for several hours or recharges a smartphone dozens of times. Recharging takes about six hours from a wall outlet or eight hours from a 12 volt vehicle socket. Solar input accepts 16.4 to 24 volts at up to 2.7 amps, though panels are not included. The battery management system shuts the unit down on overload or short circuit, so loads above 300 watts continuous cannot be sustained.

Questions about this item
Will the internal lithium battery need replacement after a certain number of cycles?
The 237 Wh lithium pack is not user-replaceable; when capacity degrades the whole unit must be replaced.
What stops the 300 W AC output from running continuously at full load?
The 375 W peak rating lasts only for short surges; sustained 300 W draw triggers thermal shutdown once the vents and BMS hit their temperature limit.
How loud are the cooling vents and how hot does the case get during all-day use?
No fan is fitted; passive vents keep the enclosure warm but silent, and the BMS shuts the unit down before components overheat.
