1) Teleworking profiles & typical needs
- Cafe/coworking : USB-C laptop, 13–16″ portable screen (10–15 W) , USB-C hub, conference call headset, smartphone.
- Nomad in van/train : same set + 4G/5G 12V router , soft LED lamp, powerbank recharge.
- Creative/tech : powerful 60–100 W laptop, NVMe SSD, portable screen, camera/photo case recharges.
- Support/Sales : Long-term calls, USB headset, 2 phones, silent battery life.
Objectives: 6–12 hours of autonomy without looking for a socket, silence , native 100W USB-C , stable network, 12V charging between two spots and MPPT for solar.
2) Choose the station: capacity, power, chemistry
-
Capacity (Wh)
- ~512 Wh : sweet spot for teleworking (laptop + screen + router + phones) 1 day.
- ~700 Wh : margin for powerful laptop/long video calls/additional charges (photo/video).
- AC 230V (pure sine) : 500–700W is sufficient for specific chargers; USB-C/12V is preferred for efficiency.
- Chemistry : LiFePO4 = longevity & thermal safety (mobile office, van, train).
- Inputs : Fast mains, MPPT for 120W panel, 12V car/train input (socket).
- Display : % + W in/out to manage the day without stress.
3) Essential ports: USB-C 100W , 12V regulated , AC sine wave
- USB-C Power Delivery 100W : laptop, portable display, hubs, SSD; uses a certified 5A e-marker cable .
- 12V regulated : 4G/5G router, soft LED, possible mini-fan (silence, efficiency).
- USB-A : 12–18W for phones, headphones, smartwatches.
- AC 230 V sinus : proprietary chargers (camera, etc.) as a last resort.
4) Laptop & portable USB-C display (10–15 W)
- 45–100W USB-C Laptop : Power it directly via USB-C PD (better efficiency/lower noise) rather than via its AC charger.
- 13–16″ portable monitor : 10–15 W typical via USB-C; ideal for spreadsheets/design/IDE → x2 productivity, minimal consumption.
- USB-C Hub : Favor hubs powered by the station to relieve the laptop.
- Ergo : laptop stand, eye level, wired keyboard/mouse (less recharging required).
5) Network: 4G/5G router , sharing, stability
- 4G/5G 12V router : 8–12W; more stable than tethering, especially for long-distance video calls.
- Optimization : position near a window, unobstructed antenna, band locking if available, lower Wi-Fi power if you are alone.
- Fallback : 20k/30k power banks for modem/phone in case of low station, then recharge at the station when solar/12V comes in.
- Security : Guest network for personal devices, corporate VPN if required.
6) Autonomy: methods & examples 512/700 Wh
Autonomie (h) ≈ Capacité(Wh) × Rendement / Charge(W)
USB-C/12 V ≈ 0,90 | AC ≈ 0,85
“Standard Coworking” profile
- Laptop 55 W × 4 h = 220 Wh; USB-C display 12W × 6h = 72; router 10 W × 6 h = 60; phones ≈ 30 Wh → ~382 Wh/d .
- 512 Wh → OK 1 day with margin; midday top-up via 120 W = total comfort.
“Intensive Video” profile
- Laptop 65 W × 6 h = 390; screen 12 W × 6 h = 72; router 10 W × 6 h = 60; miscellaneous 30 → ~552 Wh .
- 700 Wh recommended (or 512 Wh + 120 W 2–3 h + 12 V between two appointments).
“Creative/Dev” profile
- Laptop 80 W × 4 h = 320; screen 12 W × 6 h = 72; SSD/Hub 8W × 6h = 48; network 60; various 30 → ~530 Wh .
- 700 Wh → peace of mind for one day; solar at midday to complete several days.
“Van + appointment” profile
- Laptop 55 W × 3 h = 165; screen 12 W × 3 h = 36; router 10 W × 8 h = 80; 20 Wh soft LED; phones 30 → ~331 Wh .
- 512 Wh → large; recharge while driving (12 V) + a little solar.
Tip : Switch everything to USB-C/12V , keep AC for the exception → +5–10% battery life & less fan noise.
7) 120 W solar (MPPT): daily top-up
- Realistic output : 70–95 W useful in the sun (corrected angle, short & thick cables).
- Gain : 2–3 h → +140 to +285 Wh → compensates for screen + router and part of the laptop.
- Placement : kickstands, facing the sun, corrects the angle 2–3×/day; avoids partial shade (window, blind, trees).
- Workflow : Schedules loads (phones/powerbanks) during solar input → % station remains high for the afternoon.
8) Charging on the go: 12V car & GaN mains
- 12V car : 60–120W typical depending on socket/vehicle; plug in after starting , unplug before stopping .
- GaN 65–100 W : at a coworking space or at a client's, quickly fill up the mains.
- Thermal : station in the shade, ventilated , never covered during charging.
9) Organization & silence: cables, energy bag, ergonomics
- Energy bag : station + 5A USB-C e-marker cables + DC/MC4 adapters + USB power strip + Velcro winders + labels.
- Placement : off-field audio station, on the ground, ventilated; short cables, gaffed passages.
- Quiet : favors USB-C/12V to limit ventilation; avoids heavy AC loads during video calls.
- Powerbanks : 20k/30k to distribute the recharges (phones/headphones), then group recharge at the station.
10) Electrical & data safety in coworking
- Elec : respect DC polarities, no pinched cable, drip loop if outside; station placed stable.
- Data : screen lock, VPN if required, public USB ports to avoid — prioritize your station & your cables.
- Anti-theft : discreet steel cable via handle/strap, station under the table/out of sight.

15) FAQ on nomadic teleworking
USB-C 100W or AC for laptop?
Direct USB-C = better battery life & quietness. AC is used for proprietary chargers.
Is a 120W panel enough for the day?
Yes to regain +140–285 Wh in 2–3 hours of good sun, i.e. screen + router + part of the laptop.
Can I work on video calls all day?
With 700 Wh and USB-C + top-up management ( solar / 12 V ), yes. Otherwise, plan intermediate recharges.
Can the station power a 27″ screen?
Yes via AC if the display is not USB-C. But a USB-C portable display (10–15W) is much more efficient.
Pass-through & UPS, useful?
Pass-through to power while recharging; the UPS option avoids power outages in coworking spaces.
