Main strength
Some fields have documentary evidence; consult the field list and sources. Other specifications and compatibility remain pending.
We have not yet established a main strength for your use case.
Last documentary review
Official sources reviewed: 2026-10-12. Documented EU 220–240 V variant; Spanish SKU, revision and physical plug remain unverified We have not carried out physical tests.
Who it may suit
We need to check your appliances against the model’s evidence before saying who it suits. Start by calculating your consumption.
When to look elsewhere
Do not choose it if you need confirmed compatibility and information about your load or the station is still missing. Missing information is not a proven limitation.
Main trade-off
A documented interpretation of this model’s trade-offs is still needed. We do not infer portability, runtime or ease of connection from isolated figures.
What we know
Fields with documentation: nominal capacity, continuous AC power, weight, dimensions, chemistry, maximum solar input, AC sockets, number of USB ports, DC/USB output limits, connection features, solar input conditions. Each field retains its limits; this does not verify the whole model.
View sources and variant ↓What needs checking
Your setup still needs checking: startup, cables, ports and simultaneous use, operating conditions and solar installation. The offer, package contents, final price and availability are checked separately.
Next step: check your consumption and appliance connections; nominal capacity alone does not establish compatibility.

Charging and power: conditions that change the decision ↓
- Mains recharge of the whole battery
- Charging verification pending. This is a manufacturer claim under its stated conditions, not our own measurement. It is not the time to replenish your daily consumption.
- Solar input
- Solar XT60: manual 11.5–60 V, 15 A, 500 W; the EU page states a 12 V minimum. The connected array must not exceed 60 V, but explicit Voc and Isc limits remain unknown. AC input 1200 W adjustable to 400/800/1200 W; combined charging 1700 W versus 1200 W in the FAQ, with the applicable maximum unknown. Vehicle charging supports 12/24 V with the engine running; 24 V/10 A is not inferred. Peak sun hours describe equivalent energy, not clock hours at constant maximum power.
- Start-up and special modes
- Transient peak verification pending. Special modes may reduce voltage; they do not replace continuous power.
- Power supply continuity
- Transfer verification pending. An EPS/UPS function with interruption does not establish medical continuity or compatibility with all sensitive equipment.
What do watts and watt-hours represent?
The W describe power at a given moment; Whdescribe accumulated energy. Multiplying an appliance's power by its usage hours estimates energy: 100 W for 2 hours is 200 Wh consumed by the appliance. Losses mean the battery must supply more.
Phone or tablet: 15 W × 2 h = 30 Wh
Illustrative load; check charger and USB protocol.
Router: 12 W × 8 h = 96 Wh
Hypothetical constant power; confirm the power supply.
LED light: 10 W × 4 h = 40 Wh
Example of one light; add the others if used simultaneously.
Compressor fridge: 45 W × 4 h = 180 Wh
Four hours of compressor operation, not four clock hours or measured consumption.
Illustrative power and hours, not measurements of your appliances or verified runtime of this station. These Wh represent appliance consumption before losses. Check each appliance's port, voltage, protocol and start-up requirements.
Formulas and assumptions for the AC example ↓
In the example of 100 W for 2 hours, the battery would supply around 265 Wh: AC consumption ÷ 85% efficiency, plus 15 illustrative inverter watts over those two hours.With90% of the1024documented nominal Wh available, such a constant load would give approximately6.9 hours. Formula: capacity ×0.9 ÷ (100 ÷ 0.85 + 15).
Battery margin, losses and inverter consumption are planning assumptions, not measurements of this model. Temperature, ageing and variable consumption may change the result. Do not apply this AC example directly to USB or DC.
400 W of panels: generation and solar example ↓
This is nominal generation power. With 4 peak sun hours and 75% assumed solar efficiency, the example is 400 W × 4 PSH × 0.75 = 1200 Wh. This is energy equivalent to six uses of the 100 W, two-hour example before output losses, not six guaranteed uses.
ForFOSSiBOT F1800, also applying the documented solar maximum limits the example's power to400W and its indicative calculation to1200Wh.Four PSH do not mean four clock hours at a constant 400 W. Voltage, current, connectors, accessories and actual conditions must be checked; clouds or an incompatible input will change the energy. This figure is not a whole-battery recharge time either.

Model: F1800 EU, regional quantities are conditional; excludes F1200, kits and US/JP variants. Region: Documented EU 220–240 V variant; Spanish SKU, revision and physical plug remain unverified. Review date: 2026-10-12. Established fields: nominal capacity, continuous AC power, weight, dimensions, chemistry, maximum solar input, AC sockets, number of USB ports, DC/USB output limits, connection features, solar input conditions. This review does not establish price, stock, ASIN, warranty applicable to your purchase or physical testing.
Specific outstanding checks.
- Documented European revision: two AC sockets and one USB-A port; the global page lists three AC and two USB-A. Exact Spanish SKU, revision and physical plug remain unverified; do not combine regional quantities.
- Two USB-C PD ports: each advertises 140 W when used alone, but individual profiles and the PD version are unknown. With both active: 5 V/3 A and 15 W per port, 30 W total. The calculation verifies only this subset; higher power or voltage with one active port requires checking. Neither 28 V nor simultaneous 280 W is verified.
- USB-A QC3.0 up to 18 W: voltage and current profiles remain unknown; 5 V/3 A is not assumed. Vehicle output 12 V/10 A, 120 W. Aggregate DC and combined output limits are unknown; DC5521 is undocumented.
- ECO uses battery percentages, not watt thresholds: below 10% it transfers the load to mains without charging the battery; after solar charging to 30% it returns to battery power; at 5% mains charges the battery, stopping at 10%. Available mains/solar is required; settings, default state and disabling procedure remain unknown. Savings are not guaranteed.
- Idle shutoff: AC/DC after 8 h and USB after 5 min. Main power shuts off after 5 min only when all outputs are already off. Thresholds, settings and disabling procedure remain unknown; test continuity with a fridge, intermittent loads or CPAP.
- UPS: the manufacturer claims transfer within 10 ms with main power and AC on; mains → station → load in bypass. Measured transfer time and bypass limit remain unknown; neither 0 ms nor medical certification is verified. CPAP and the specific load require checking.
- Startup remains unverified: specifications advertise 3600 W, while the FAQ states 2700 W for 0.4 s; no single surge rating is adopted. Constant-power mode for resistive appliances rated up to 2400 W does not replace normal 1800 W output; mechanism, activation, default state and bypass availability are unknown.
- Solar XT60: manual 11.5–60 V, 15 A, 500 W; the EU page states a 12 V minimum. The connected array must not exceed 60 V, but explicit Voc and Isc limits remain unknown. AC input 1200 W adjustable to 400/800/1200 W; combined charging 1700 W versus 1200 W in the FAQ, with the applicable maximum unknown. Vehicle charging supports 12/24 V with the engine running; 24 V/10 A is not inferred.
- App with 2.4 GHz Wi-Fi/Bluetooth; version and settings remain unknown. External expansion supports 12/24/48 V up to 15 A with a separate cable and app activation; restarting disables the function, and car charging is prohibited in this mode. Specific compatible batteries and maximum capacity remain unverified.
- Charging 0–40 °C; discharging −10–40 °C. Power reduction above 40 °C refers to internal temperature, not ambient temperature. Cycles, warranty, exact recharge time, price, stock, ASIN, image and reviews remain unverified.
