Detailed overview: Fossibot F3600 Pro 3840Wh power station
The Fossibot F3600 Pro is a high-end portable power station aimed at those with heavy energy needs: long camping trips, vans, home backup power or worksites. It combines a capacity of 3840Wh and an output of 3600W, with a 7200W surge to absorb power-hungry devices at start-up.
Its main strength is its expandability: the base 3840Wh capacity can be raised to 11520Wh by adding extra batteries, letting you size your reserve to your real needs and consider multi-day backup power. The battery uses LiFePO4 (lithium iron phosphate) cells, known for their safety and longevity, with over 4000 cycles while keeping a high capacity.
For practicality, the F3600 Pro relies on ultra-fast dual-mode charging that fills up in record time from the mains, complemented by a solar input for self-sufficient recharging. It includes a UPS mode that switches to battery almost instantly during an outage, protecting computers, internet routers and sensitive devices. App control (WiFi and Bluetooth) lets you monitor the charge, adjust settings and track consumption remotely.
It offers a wide range of ports (AC outlets, USB-C Power Delivery, USB-A, car output) to power many devices at once. Mounted on wheels with a telescopic handle, it moves despite its substantial weight. Against the Fossibot F2400 (2048Wh, 2400W) already in the catalogue, the F3600 Pro clearly targets the top tier: more power, more reserve, and expandability on top.

Rough estimate: real consumption varies, and very power-hungry appliances (heating elements) must stay below the output power.
What is this power station best for?
-
Home & Power cuts Ideal
With 3840 Wh and 3600 W, the Fossibot F3600 Pro durably secures a home during an outage, freezer and large appliances included, at an excellent capacity-to-price ratio: its UPS function switches over in 10 ms for an invisible transition, and its 7200 W peak absorbs the most violent startup surges. Its expansion to 11,520 Wh covers multi-day outages, and its LiFePO4 battery rated for 6500 cycles, one of the most durable in its class, ensures a very long lifespan. Its solar input up to 2000 W makes it a reserve you can refill fast in the sun. A powerful, scalable, durable home backup at a price well below premium references.
-
Job site & Tools Ideal
On a demanding off-grid site, the Fossibot F3600 Pro combines a large reserve and strong power at a contained price: its 3600 W (7200 W peak) start and run heavy tools, a circular saw, grinder, compressor or a small welder, and its four outlets feed an entire mobile workshop for a full workday. Its 3840 Wh, expandable to 11,520 Wh, cover the most intensive uses, and a solar input up to 2000 W recharges quickly on site in good weather. Its battery rated for 6500 cycles withstands daily professional use for years. At 42 kg, position it at a central point of the site rather than moving it constantly.
-
Off-grid & Solar Ideal
Expandable to 11,520 Wh and fitted with a strong solar input (up to 2000 W), the Fossibot F3600 Pro forms an economical storage core for autonomous living in a cabin, workshop or off-grid second home. Its 3600 W and 7200 W peak power a fridge, pump, tools and large appliances without compromise, and in good weather it banks solar energy at a good rate. Its battery rated for 6500 cycles withstands years of daily cycling, a real asset for storage used year-round. It offers premium-level capacity and power at a much more accessible price, ideal for sizing an autonomous installation without breaking the budget.
-
Motorhome & Van life Suitable
Its 3840 Wh bring very broad autonomy in a motorhome: fridge, electric cooking, a booster water heater and comfort run for several days in a row, and its 3600 W accept hungry appliances without compromise, light air conditioning included. Its expansion to 11,520 Wh targets a genuine week of autonomy on long trips, and a solar input up to 2000 W recharges quickly at a stop in good weather. Its attractive capacity-to-price ratio makes it a top option to equip a large vehicle without a premium budget. At 42 kg, it is reserved for motorhomes and A-classes with a dedicated bay, where it is installed permanently.
-
Events & Market stalls Suitable
Quiet and generous with energy, the Fossibot F3600 Pro cleanly powers a market, a stand or an outdoor event without the noise or smells of a fuel generator: its 3600 W handle a substantial PA system, lighting, a control desk and catering gear, and its 3840 Wh cover a very long day. Its expansion to 11,520 Wh lets you run several days in a row or absorb consumption peaks, and a solar input up to 2000 W supplements autonomy at long events. Its accessible price against premium stations makes it a reliable alternative to a generator for budget-conscious associations, organisers and providers.

Comparison
How does the Fossibot F3600 Pro compare with the F2400?
| Criterion | Fossibot F3600 Pro | Fossibot F2400 |
|---|---|---|
| Capacity | 3840Wh | 2048Wh |
| Power | 3600W (7200W surge) | 2400W |
| Expandable | Up to 11520Wh | No |
| Battery | LiFePO4 | LiFePO4 |
The F3600 Pro brings nearly twice the capacity and 1200W more power than the F2400, plus the option to expand the reserve to 11520Wh. The F2400 stays lighter and enough for camping or occasional backup, while the F3600 Pro targets heavy needs and prolonged backup power. Both benefit from the reliability of LiFePO4 cells.

Our tester's review: Christophe Delpuech
The Fossibot F3600 Pro clearly plays in the big-station league, at a price that stays aggressive. What strikes you first is the power: with 3600W continuous (and a 7200W surge), it handles an induction hob, a space heater, a kettle or power tools without flinching, where 2000W stations stall. Its 3840Wh reserve lasts a good day for a fridge plus a few devices, and above all, you can add batteries to climb to 11520Wh, enough for real multi-day backup power. LiFePO4 technology reassures on lifespan (4000+ cycles) and safety. In use, the ultra-fast charging is a real comfort: you fill up in a handful of hours from the mains. The UPS mode switches over fast enough to protect a computer or a router during an outage, and the app lets you monitor and adjust the station remotely. The wheels and handle are welcome given the substantial weight. The only small caveats: it stays heavy and bulky (the price of capacity), and the fan is audible under heavy load. But for anyone after a powerful, expandable and durable station, the F3600 Pro is excellent value.
