Télétravail mobile : 8–10 h d’autonomie

Mobile teleworking: 8–10 hours of battery life

Power stations for mobile teleworking : USB-C display , 5G router , 100W laptop and 8–10 hours of battery life - the 2025 guide

Do you want to work anywhere (home, terrace, coworking, van, professional salon) while keeping a USB-C screen , a 60–100 W laptop and a 5G router online without stressing about the socket? Here is our nomadic teleworking method: choose the appropriate energy station (power station/solar generator), wire in direct USB-C PD 100 W (better efficiency than AC 230 V), size the capacity (Wh) to aim for 8–10 h , add a foldable 120–160 W solar panel (MPPT) to recharge at lunch, and secure your setup (UPS, certified 5A cables).

1) Target: 8–10 hours of real-life battery life

Your typical position:

  • USB-C Laptop : 45–100 W depending on load (dev/edit/visi).
  • 13–16″ USB-C portable monitor : 8–15 W.
  • 5G router or access point: 8–12 W (12 V or USB-C).
  • Accessories : SSD, hub, smartphone (10–20 W one-off charging).

We're aiming for a 512-700 Wh station to last the day, with a 100 W USB-C output for the laptop and 12 V/USB outputs for the rest. If you're very light (a simple laptop, without a screen), ~300 Wh may be enough.

2) Optimal power supply scheme ( USB-C > AC )

  • USB-C PD priority : powers the laptop with 100W USB-C directly from the station → better performance , less noise (fans), increased battery life.
  • USB-C display : Power it via another USB-C/USB-A output (if the display supports 5/9/12/15V) or via a small 12V → USB-C socket (depending on the display). Avoid using AC if possible.
  • 5G router : if it accepts 12V , connect it to the station's regulated DC output (+ output). Otherwise, use USB-C.
  • AC 230V pure sine wave : keep it for exceptional use (photo charger, non-USB-C screen, etc.).

3) Choose your station: W , Wh , LiFePO4 , MPPT

  • Inverter power : 500–700 W continuous (peak ≥900 W) is sufficient for teleworking uses (non-USB-C screen, chargers, etc.).
  • Ability :
    • ~300 Wh : minimal setup (laptop only, without external screen).
    • ~512 Wh : sweet spot 8 h with screen + router.
    • ~700 Wh : 8–10 h comfort + visibility/rendering margin.
  • Chemistry : LiFePO4 recommended (longevity, thermal stability, high cycles).
  • Ports : Must have USB-C PD 100W (C1 priority), 12V regulated 10–15A, fast USB-A.
  • Inputs : Fast mains, integrated solar MPPT (for 120–160 W panel), 12 V car input while driving.
  • Display : % battery + W in/out to control your consumption.

See our 300/512/700 Wh stations

4) USB-C Display: 8–15W typical, daisy chain & hubs

  • Power consumption : A 13–16″ USB-C portable monitor often consumes 8–15 W (30–60% brightness).
  • Connection : plug it into a USB-C output on the station (if profile compatible) or via a USB-C hub powered by the station; otherwise, in regulated 12 V (adapter depending on screen).
  • Daisy chaining : If your laptop supports two displays via a USB-C hub, check the available power per port so as not to choke the laptop's 100W output.
  • Settings : decrease brightness by 10–20% → visible battery life gains .

5) 4G/5G router & modem: 8–12 W, stability & cabling

  • Power supply : if 12V router → uses the station's regulated 12V output (efficiency + stability). USB-C router → 15–30W USB-C output.
  • Placement : Keep it away from your laptop's power cables to limit interference. If indoors, place the antennas toward the window.
  • Eco mode : lowers Wi-Fi/5G power when you are alone, cuts unnecessary bands → you save Wh over the day.

6) Autonomy calculation: formulas & examples (300/512/700 Wh)

In USB-C/12V direct, has an efficiency of ~0.90 (vs ~0.85 in AC).

 Autonomie (h) ≈ Capacité(Wh) × Rendement / Charge(W)

Typical profile : 60W laptop (average), 12W screen, 10W router → 82W continuous charge.

  • 300 Wh : 300 × 0.90 / 82 ≈ ~3.3 h .
  • 512 Wh : 512 × 0.90 / 82 ≈ ~5.6 h .
  • 700 Wh : 700 × 0.90 / 82 ≈ ~7.7 h .

Tip : In practice, the laptop does not draw 60 W continuously. In office/video applications, we often see 35–55 W → the 512 Wh reaches ~7–8.5 h ; the 700 Wh exceeds 8–10 h .

7) Solar charging at lunch: 120–160 W (MPPT)

  • Objective : to regain 150–300 Wh during the break (2–3 hours of good sun) with a 120–160 W foldable panel .
  • Realistic : 120 W → 70–95 W useful; 160 W → 110–135 W useful (angle, weather, short cables).
  • Recommended torque : 512 Wh → 120–160 W; 700 Wh → 160 W.
  • USB-C direct : for power banks/phones, uses the panel's USB ports if available, while charging the station via MPPT.

See 120–160 W panels

8) Micro-cuts & UPS : zero call interruptions

  • UPS mode : some stations automatically switch from mains to battery (short transfer time). Ideal for video/network.
  • Diagram : mains → station (input); laptop/router/screen → station (outputs). In case of power outage, the station takes over without any noticeable interruption.
  • Tip : test UPS mode during the day (5 min) to validate your setup.

9) Noise, heat, placement & ergonomics

  • Fans : More discreet with direct USB-C than with AC. Place the station on a hard, ventilated surface .
  • Heat : Avoid direct sunlight; the hotter it is, the more the power is limited.
  • Cables : USB-C 100W (5A e-marker) for laptop; length 1–2m max.
  • Organization : A quality short power strip is enough when you need to use the AC (printer, photo charger).

14) FAQ teleworking & stations

512 Wh or 700 Wh for a real day?

512 Wh is often enough (65–80 W profile). If you draw more (100 W regular, dual screen, rendering), take 700 Wh + 160 W panel.

USB-C 100W mandatory?

Recommended. Your laptop negotiates its power; having 100W gives you some leeway and avoids switching to AC.

Can I connect everything to 230V AC?

Yes, but you lose 5–10% battery life vs USB-C/12V. Save AC for the exceptional.

Is solar energy useful in cities?

On a balcony/terrace, a 120–160 W easily regains 150–300 Wh during the break, or 1–3 hours of autonomy.

And by plane?

Stations often exceed 100 Wh → restrictions. For air travel, carry a 26.8–30k mAh power bank (check your airline's 100–160 Wh policy).
