FOSSiBOT F800
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: 2026-10-11. EU documentation: 220–240 V; selectable 220/230 V and 50/60 Hz, current/default setting and Spanish 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, solar input conditions, DC/USB output limits, AC sockets, number of USB ports, connection features. 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 11.5–50 V, 8 A, up to 200 W; FAQ 12–50 V and below 8 A, with the 112 V–50 V typo discarded. No explicit Voc rule: verify panel, temperature, current, polarity and cable. AC up to 400 W is not adjustable; AC+solar is allowed but combined maximum is unknown, not assumed to be 600 W. Vehicle typically 90–120 W with the engine running, input voltage range unverified; do not assume 12/24 V. 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 the512documented nominal Wh available, such a constant load would give approximately3.5 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 F800, also applying the documented solar maximum limits the example's power to200W and its indicative calculation to600Wh.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.

Specific outstanding checks.
- Documented 512 nominal Wh LFP, 800 W TOTAL nominal AC, 6.5 kg and 276 × 209 × 230 mm. One EU AC 220–240 V; selectable 220/230 V and 50/60 Hz. 230 V is an option, not a verified current or default setting; SKU and Spanish plug remain unverified. Usable energy has not been measured.
- Automatic shutdown/ECO still needs checking: support, thresholds, timers and current settings are unknown. Do not borrow timings from another model or guarantee continuity with low/intermittent loads, fridges or CPAP. The official F800 comparison indicates no app; no documented expansion.
- USB-A: 2 QC3.0 up to 18 W per port, with V/A profiles and negotiation unverified; do not assume 5 V/15 W or PD compatibility. USB-C: 2 PD of 20 W and 1 PD of 100 W with V/A profiles unverified. Shared groups, aggregate DC maximum and total for all outputs are unknown; do not add maxima as simultaneous power.
- Vehicle 12 V/10 A, derived 120 W. DC6530 12 V/10 A, derived 120 W, documented but not assignable in the engine: not DC5521, with no assumed adapter or compatibility.
- Advertised 1600 W surge without duration/conditions: startup power and duration are unverified; advertised 840 W protection does not extend 800 W continuous power. European UPS in bypass requires load below 800 W, unit on and AC plug connected for simultaneous charging/discharging. The manufacturer states switching within 10 ms, not an exact verified time or zero interruption; medical/CPAP use and the specific load require testing.
- Cycle life still needs checking: a 3500+ claim at 80% without equivalent test conditions. Applicable warranty remains unverified: manual 24 months versus website 5 years/2+3. Price, stock, ASIN, photo, reviews and verified recharge time remain unknown.
- Solar XT60: manual 11.5–50 V, 8 A, up to 200 W; FAQ 12–50 V and below 8 A, with the 112 V–50 V typo discarded. No explicit Voc rule: verify panel, temperature, current, polarity and cable. AC up to 400 W is not adjustable; AC+solar is allowed but combined maximum is unknown, not assumed to be 600 W. Vehicle typically 90–120 W with the engine running, input voltage range unverified; do not assume 12/24 V.
- Temperature: charging 0–40 °C; manual operating -10–40 °C versus FAQ -15–40 °C. Universal minimum discharge temperature unverified; do not certify -15 °C. An external video title of 576 Wh does not replace the 512 Wh on the model’s own page.
