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 below 300W.

For a FlashFish T300PRO bulk enquiry, identify the exact model and intended destination. Use the specifications above to compare the electrical connections, dimensions and operating limits that apply to this product. Share your planned order quantity with RuggedMaster so the enquiry can be matched to the correct listing.
When preparing your purchasing checklist, distinguish energy capacity from output power. Check the continuous rating, connector type and input limits where listed. Match each connection to the equipment in your setup. For solar systems, review the panel output and the connected power station input together, as the receiving device can limit charging power.
The product gallery presents official photographs and, where needed, manufacturer feature illustrations. Expansion setups and other equipment shown in feature artwork illustrate compatible applications. Check the package contents and exact model specification to confirm what belongs to the product you are enquiring about. These images do not create separate purchasable variants.
Use the FlashFish T300PRO Specs tab alongside the description images when comparing products for your business. Verify the required voltage, connector fit and polarity before arranging a charging setup. For battery products, consider both the expected load and the manufacturer operating conditions. Actual charging performance and runtime vary with the connected equipment and environment.
Keep the full model name with your procurement records. If you are planning a repeat order, use that name to identify the same configuration and category. Contact RuggedMaster with the quantity, destination and intended application so the required product can be discussed clearly. Refer to the official specifications rather than estimating compatibility from appearance alone.
