Power stations for hiking & car bivouacs : 12V coolers , LED , 100W USB-C , 120W panels (MPPT) & 12V charging - 2025 guide
Whether you're going light on a hike with a minimalist bivouac or traveling in a car bivouac (wild camping, mountain spot, beach), energy must be simple , reliable and silent . In this guide, we size energy stations ( power station/solar generator ) 300–512 Wh with regulated 12 V , 100 W USB-C , pure sine AC and MPPT for 120 W foldable panels , we optimize 12 V coolers (compressor), we light with safe LEDs , we recharge in 12 V cars and we stay safe (non-electric stove, ventilation, heat management).

1) Profiles: light hiking vs. car bivouac
- Lightweight hiking : 1–3 days, tent/tarp, 10k/20k power banks , small LED lamp , smartphone/GPS charger, no cooler . Compact station option to leave at camp/car.
- Car bivouac : 1–7 days, 12V compressor cooler , LEDs, USB fans , recharges (smartphones, cameras, drone), sometimes USB-C laptop , 100–120W solar top-up.
- Outdoor photo/video : numerous batteries to recharge (USB-C/DC chargers), priority autonomy + silence.
- Family : several phones/tablets, LED garlands, cooler , children's night light, low-power music.
Objectives: minimum 24-hour battery life , easy recharging (USB-C & 12 V), safety at camp, silence at night.
2) Choose the station: 300–512 Wh , power & chemistry
-
Capacity (Wh) :
- ~300 Wh : minimal bivouac (LED + recharges + small cooler very economical in mild weather).
- ~512 Wh : sweet spot car bivouac (compressor cooler + LED + recharges + occasional laptop).
- Inverter power : AC 500–700 W (pure sine) is sufficient (specific chargers, occasional inflator). Keep AC for the exception → prefer 12 V/USB-C .
- Chemistry : LiFePO4 = longevity & thermal stability (excellent in summer heat if ventilated/shaded).
- Inputs : Fast mains, built-in MPPT (100–120 W solar), 12 V car input.
- Display : % battery + W in/out = end day/night control.
3) Useful ports: 12V regulated , USB-C 100W , AC sine
- 12 V regulated (cigarette lighter socket + DC outputs): cooler , fans, shower pump, 12 V LED strips.
- USB-C Power Delivery 100W : laptop , portable display, hubs, fast charging power banks. Uses a 5A e-marker cable .
- USB-A : 12–18 W for lamps, headlamps, phones.
- AC 230 V (sine) : for specific chargers (drone/camera) occasionally .
4) 12 V cooler (compressor): consumption, settings & wiring
- Compressor : 35–60 W running; ~200–450 Wh/d depending on volume, insulation, weather, setpoint.
- Settings : pre-cooled at home; puts food already fresh; setpoint 4°C day / 6–7°C night; shade and ventilation.
- Connection : regulated 12V output from the station. Short & thick cable (2.5–4 mm²) to avoid voltage drops (unexpected power cuts).
- Thermoelectric : simple but power-hungry in high heat (300–600 Wh/day) → more for cool weekends.
5) Cooking in bivouac: non-electric stove , safety, heat management
- Non-electric stove (gas, alcohol, solid fuel): use outdoors or in a highly ventilated shelter. Follow the manufacturer's instructions, keep fabrics and the station away.
- Never have a flame near the station or cables. The station remains in the shade , on a hard, uncovered surface.
- Heat management : cook outside the tent/trunk; cool dishes before putting them in the fridge; open the cooler quickly and infrequently .
6) LED lighting: flow, consumption & atmosphere
- 12V garlands/ribbons : 2–6W/m dimmable → soft light under awning/trunk.
- Camp spotlight : 5–15 W for cooking/walking. Temperature 3000–4000 K = visual comfort.
- USB headlamps : USB-A/C charging from the station or power bank .
7) Autonomy: methods & examples (day/week)
Autonomie (h) ≈ Capacité(Wh) × Rendement / Charge(W)
USB-C/12 V ≈ 0,90 | AC ≈ 0,85
“Summer car bivouac” profile : cooler ~300 Wh/d, LED 40 Wh, USB fan 30 Wh, recharges 40 Wh → ~410 Wh/d .
- 512 Wh → 1 day without recharging; aim for a 120 W panel to last the week.
“Photo/video” profile : 120 Wh camera/drone recharges + 55 W USB-C laptop × 2 h (110 Wh) + 30 Wh LED → ~260 Wh/d .
- 300 Wh → 1 day; 512 Wh → 2 days without solar.
“Family” profile : 350 Wh cooler + 50 Wh garlands + 4 60 Wh phones + 20 Wh tablet → ~480 Wh/day .
- 512 Wh → OK with 12 V charging while traveling or 120 W 2–3 h/day.
Tip : favor USB-C & 12 V (efficiency ↑), keep AC for the exception → +5–10% autonomy.
8) Solar 100–120 W (MPPT): daily top-up
- Realistic output : 100 W → 60–85 W usable; 120 W → 70–95 W usable (corrected angle, short/thickened cables).
- Gain : 2–3 h → +120 to +285 Wh , ideal for compensating for the cooler.
- Placement : Kickstands facing the sun, corrects the angle 2–3×/day; avoids shadows (tree, open trunk).
- Connection : MC4 → station DC adapter; integrated MPPT = better efficiency.
9) 12V car charging (alternator)
- Power : 60–120 W typical depending on socket & vehicle.
- Good reflex : plug in after starting , unplug before switching off (avoids voltage dips).
- Heat : Do not cover the station, keep it in the shade and ventilated while charging.
- Fuses : Respect the amperage of the socket (often 10–15 A). Use the manufacturer's cable.
10) Organization: bag & trunk (energy kit)
- Hiking kit : 10k/20k power bank + USB-C cable + mini USB lamp + phone in eco mode.
- Car bivouac kit : 512 Wh station + 120 W panel + USB-C 5A e-marker + DC splitter for LEDs/fans + short/thick cables.
- Storage : ventilated box, tie-down straps , line label (cooler/LED/USB-C), accessory pocket.

15) Hiking & bivouacking FAQ
12V cooler: compressor or thermo?
Compressor for autonomy (200–450 Wh/d). Thermo = simple but greedy in summer (300–600 Wh/d).
USB-C 100W or AC for laptop?
Direct USB-C = better battery life & silence. Keep AC for the exception.
Is a 120W panel enough for a week?
Yes to compensate for the majority of the cooler if 2–3 hours of good sun/day, corrected angle and short/thick cables.
Can I cook near the station?
No. Keep distance and ventilation between flame and station/cables. Cook outdoors or under a well-ventilated awning.
Can the station stay in the trunk overnight?
Yes, if dry , ventilated , uncovered and tied down . Avoid full sun exposure during the day.
