FlashFish T300PRO is a 230Wh LiFePO4 portable power station for the U.S. market, with 120V/60Hz pure sine wave AC output rated at 300W continuous and 600W peak. The U.S. manual lists a 4.5kg (9.9lb) net weight, 120W maximum DC/solar input, USB-C input and output up to 100W, and EPS emergency backup with switching within 20ms. Power and battery The T300PRO battery is rated at 230Wh (12.8V, 18Ah). Its LiFePO4 cells are specified for more than 3,500 cycles while retaining more than 80% capacity under the manual’s stated test basis. Actual runtime depends on the connected load, conversion losses, temperature, battery condition, and output path. Charging options AC input: 120V, up to 230W; the manual states a full AC charge in less than 1.2 hours under the documented conditions. DC/solar input: DC7909, 12–30V, 8A, up to 120W. For solar charging, use a compatible panel, connector, polarity, and the documented cable. USB-C1 input: PD 5–20V, up to 100W. Outputs Output U.S. specification AC outlets 120V/60Hz pure sine wave; 300W continuous, 600W peak USB-C1 Up to 100W input/output USB-C2 Up to 30W output USB-A1 Up to 18W output USB-A2 Up to 12W output 12V DC outputs Cigarette lighter, DC5521 and DC5525 share a combined 120W maximum EPS emergency backup The T300PRO supports EPS emergency backup and can switch to battery power within 20ms after grid power fails. The manual identifies this as a non-professional backup function rather than a 0ms UPS. Do not use it for equipment that requires uninterrupted power, such as data servers or workstations. Size, protections and compatibility Dimensions: 256 × 169 × 169mm (10.06 × 6.65 × 6.65in) Net weight: 4.5kg (9.9lb) Protections: high and low temperature, over-discharge, over-charge, overload, short-circuit, and over-current protection Check each device’s continuous draw, startup demand, voltage, plug, and waveform requirements before use. A 300W rating does not guarantee compatibility with every device whose typical draw appears be
