Detailed overview: Fossibot DC mini power station with fan
Unveiled by Fossibot at IFA 2026 (Berlin, 4-8 September), the FDC300 takes an unusual approach for a portable power station: no 230V/120V AC outlet at all. All its power runs through USB, making it more of a supersized power bank than a classic power station, built for nomadic electronics rather than appliances.
Its 288 Wh LiFePO4 battery can power up to four devices at once: two USB-C ports deliver up to 140W each (200W combined), support Power Delivery 3.0, and are bidirectional, so they can charge a laptop or recharge the FDC300 itself from a powerful USB-C adapter. A third USB-C port tops out at 30W, and one Quick Charge 3.0 USB-A port adds 18W. On the input side, an XT60 connector accepts up to 120W from solar panels or a 12V vehicle socket, for a full charge in about 2h40 that way, or as fast as 1h14 combining both 140W USB-C ports. A built-in screen constantly shows charge status and current power draw.
Its most visible feature remains the built-in folding personal fan, with three speeds and a "natural wind" mode, able to run for up to 100 hours on that function alone on a full battery. A built-in light and a hidden phone stand under the housing round things out, handy for watching a video while charging your phone. It all fits into a compact 135 x 135 x 205 mm footprint at 2.7 kg, with a rated discharge temperature range of -10 °C to 40 °C.
The FDC300 is a lightweight companion rather than a home backup station: with no AC outlet, it can't power a fridge or small appliances. It targets a much narrower niche, somewhere between a light mobile office, a bivouac companion, and a cooling boost, where its fan, light, and powerful USB-C ports set it apart from a regular power bank.

⚡ How long will this power station run a device?
With 288 Wh, the Fossibot FDC300 external battery runs a fridge (50 W) for ~4h55 or an LED TV (90 W) for ~2h45.
| Home | Runtime |
|---|---|
| Mini fridge (45 W) | ~5h25 |
| Refrigerator (50 W) | ~4h55 |
| Freezer (60 W) | ~4h05 |
| American fridge (150 W) | ~1h40 |
| Outdoor & workshop | Runtime |
|---|---|
| Wi-Fi router (15 W) | ~16h |
| Electric cooler (45 W) | ~5h25 |
| Laptop (60 W) | ~4h05 |
| Nebulizer (100 W) | ~2h25 |
Rough estimate: real consumption varies, and very power-hungry appliances (heating elements) must stay below the output power.
Comparison
Around €159, the Fossibot FDC300 sits in an unusual niche between a premium power bank and a mini power station, searched for as "USB-C power station no AC" or "power bank with fan". Here's how it compares to three close profiles: Fossibot's own F1200, a proper station with an AC outlet; the Anker Prime 27,650mAh, a premium power bank with no fan; and the Baseus Blade2, a compact, fast-charging USB-C power bank.
| Criterion | Fossibot FDC300 | Fossibot F1200 | Anker Prime 27,650mAh | Baseus Blade2 |
|---|---|---|---|---|
| Capacity | 288 Wh | 1024 Wh | ≈ 99.5 Wh | ≈ 96 Wh |
| AC outlet | No | Yes (2 sockets, 1200W) | No | No |
| Fastest port | USB-C 140W | USB-C 100W | USB-C 140W | USB-C 100W |
| Built-in fan | Yes, 3 speeds | No | No | No |
| Weight | 2.7 kg | 11.5 kg | ≈ 0.74 kg | ≈ 0.62 kg |
| Price observed | €159 | ≈ €550 | ≈ €220 | ≈ €130 |
In short, the FDC300 sits in a category of its own: it comfortably outdoes a regular power bank on capacity and versatility (fan, light, phone stand), without rivalling a proper station like the F1200, which remains essential whenever an AC outlet is required. Against premium power banks like the Anker Prime, it offers more runtime but weighs noticeably more.
Frequently asked questions: Fossibot DC mini power station with fan
No, it's a 100% DC station: all its power comes out through its USB-C and USB-A ports. It can't power a device that plugs into a standard AC socket, unlike other Fossibot stations such as the F1200.
Up to 100 hours using only that function on a full battery, with 3 adjustable speeds and a "natural wind" mode that varies intensity for a more pleasant airflow.
Around 1h14 to 1h36 combining both 140W USB-C ports, 2h17 through a single USB-C port, or 2h40 via solar or a 12V vehicle socket through the XT60 connector (120W max).
Yes, as long as the laptop charges over USB-C Power Delivery: the two main ports deliver up to 140W each, enough for the vast majority of USB-C laptops on the market.
Yes, it has just launched (unveiled at IFA 2026) and is in stock, priced at €159, with a 3-year manufacturer warranty.
Yes, alongside the folding fan, the housing includes a built-in light and a screen that constantly shows charge status and power draw.
