Our verdict
A device charger, not a power station. At 8.27 lb and 288Wh it's for phones, laptops and a CPAP — nothing with a heating element or compressor.
Best for: CPAP users and travelers who need days of small-device power in a bag.
What we like
- 8.27 lb — light enough to carry one-handed all day
- LiFePO4 at a $299 entry price
- Runs a CPAP for multiple nights
Where it falls short
- 300W output rules out almost every appliance
- 288Wh is a single laptop-day of capacity
