VTOMAN FlashSpeed 300 Portable Power Station, 300W, 230Wh

- 230Wh, 300W, 7.4 lbs
- 100W PD USB-C dual input/output
- 6x longer lifespan, 3000+ cycles
Our take
Seven output ports charge 7 devices simultaneously including 2 AC outputs, the 100W USB-C, 3 USB-A, and a DC port, covering smartphones, speakers, cameras, camping lights, drones, and CPAP machines all at once.
Why it made the shortlist
A genuine 100W PD USB-C input recharges this to 80% in about 2 hours, and the same port doubles as both input and output for MacBooks, Dell XPS laptops, or high-end drones. At just 7.4 lbs, an advanced LiFePO4 battery engineered for over 3000 cycles delivers a documented lifespan 6 times longer than conventional batteries.
Four flexible recharge methods (wall socket in 2.5 hours, solar panel, car outlet compatible with 12V/24V vehicles, or the 100W USB-C input) give genuine flexibility, with a built-in 3-mode LED light adding steady, strobe, and SOS illumination.
What works
- 100W USB-C port genuinely works as both fast input and output
- 7.4 lbs is genuinely light for this capacity class
- 4 flexible recharge methods including a dedicated car-outlet path
Watch out for
- 300W output limits this to lighter device charging
- 230Wh capacity is modest for anything beyond personal electronics
