1) Why a 30k mAh laptop?

  • True reserve : 30,000 mAh at 3.7 V ≈ ~111 Wh . Enough for +1 full cycle on many ultrabooks (or 2–4 smartphone/tablet cycles).
  • Usable power : 65–100W PD outputs to keep up with the demand of a MacBook Pro/Air, ThinkPad, XPS, etc.
  • Versatility : also charges PPS smartphones (Galaxy/Pixel), USB-C cameras, 5G routers, iPad/console.
  • Nomadic format : more compact/cabin-approved (depending on the company) than an energy station .

2) 65–100W USB-C PD outputs & multi-port splitter

  • PD profile : aim for 20V 5A (100 W) or at least 20V 3.25A (65 W) for laptops.
  • Distribution : in multi-ports, the power is shared . Common example:
    • Solo C1 → 100 W;
    • C1 + C2 → 65 W + 30 W ;
    • C + A → 87 W + 18 W (depending on model).
    Read the sheet to know the exact PD levels simultaneously.
  • Peak vs. sustained : Some power banks advertise 100W max but sustain 65–87W for a long time. Favor “100W continuous ” models.
  • Protection : BMS (OVP/OCP/OTP/UVP), cell balancing, fireproof/shockproof case welcome.

3) 5A e-marker & safety cables (20 V 5A)

  • Essential : To output 100W , use a 5A USB-C cable with e-marker (certified 100/240W). A 3A cable will limit to 60W.
  • Length : 1–2 m max for minimum voltage drop; avoids series extension cords.
  • Elbows : practical for mobility (train/plane) to relieve the connector.
  • Choose a 100W (5A) USB-C cable

4) Laptop & console compatibility (Mac/Win/Switch/Steam Deck)

  • MacBook Air/Pro : 30–100W depending on model/task. For office work, 65–87W output is often sufficient; for rendering/compiling, aim for 100W .
  • Windows Ultrabooks (XPS, ThinkPad, ZenBook, etc.): Typical 45–65W profiles. 65W is the sweet spot ; 100W = headroom.
  • Compact USB-C gaming devices : Additional charging is possible, but the proprietary adapter remains more powerful. The power bank slows down the discharge or maintains it depending on usage.
  • iPad/Android tablet : 20-45W PD/PPS.
  • Switch/Steam Deck/ROG Ally : 15–45 W depending on console and performance mode.

5) PD vs PPS : what are the useful differences?

  • PD (Power Delivery): fixed profiles (5/9/12/15/20 V). Standard for laptops.
  • PPS (Programmable Power Supply): Finely adjusted voltage/current (e.g. 3.3–21 V). More stable and often cooler charging on compatible Galaxy/Pixel.
  • A PD + PPS power bank maximizes smartphone compatibility while managing the laptop.

6) Inputs & fast charging: 45–100 W, GaN & pass-through

  • USB-C input : Targets 45–100W (PD) input for fast charging.
  • Typical times (30k ≈ 111 Wh):
    • 45 W input → ~ 3–3.5 h ;
    • Input 65 W → ~ 2–2.5 h ;
    • Input 100 W → ~ ~1.5–2 h (depending on thermal & absorption curve).
  • GaN charger : compact & cool. Take a 65–100 W with 5 A cable.
  • Pass-through : some models power the laptop while charging . Practical in the office/hotel, avoid 24/7 if unnecessary.
  • Solar : possible via a foldable PD panel (18–45 W) for backup/ground.

7) Real autonomy: formulas & examples

Between conversion, heat & cables, a power bank rarely delivers 100% of its Wh. It counts ~0.85 in practice on a laptop.

 Autonomie (h) ≈ Capacité(Wh) × 0,85 / Charge(W)
  • 45 W Ultrabook : 111 × 0.85 / 45 ≈ ~2.1 h of continuous use (more if office use because consumption varies).
  • 60 W Ultrabook : 111 × 0.85 / 60 ≈ ~1.6 h .
  • MacBook Pro under heavy load 85–100W : 111 × 0.85 / 90 ≈ ~1.05 h ; at 100W sustained, the power bank can simply stabilize the internal battery.
  • iPad 30 W : 111 × 0.9 / 30 ≈ ~3.3 h of equivalent power (or 2–3 charges depending on model).

Tip : plug in directly via USB-C (not via a big, power-hungry dock), lower the brightness & close heavy apps to save hours.

8) Airplane: ~111 Wh , cabin, 100–160 Wh

  • Cabin only : power banks in cabin baggage (never in the hold).
  • ≤100 Wh : generally OK without formalities .
  • 100–160 Wh (so 30k ≈ 111 Wh): often with the airline's agreement and in limited quantity. Check the rules before the flight.
  • Clear label : choose models with the “Wh” marking.

Tip : If you fly a lot and your airline is strict, consider a 26,800 mAh (≈99.2 Wh) PD 65–100 W.

13) FAQ power banks 30k mAh

Is 100W “too much” for my laptop?

No. The laptop negotiates the PD power it needs. Having 100W just provides headroom under heavy load.

Why is my power bank capped at 60W?

Check the cable (5A e-marker required), the port used (C1 often has priority), the temperature (throttle) and simultaneous uses (distribution).

Pass-through = UPS for PC?

No. Pass-through is helpful but not a real UPS. For automatic mains-to-battery switching, get a station with a UPS .

30k mAh on a plane?

~111 Wh → cabin, usually with airline agreement (100–160 Wh). Some require written approval.

I want more autonomy than 30k

On a plane, it will be complicated. On the ground, add a 300–700 Wh power station as needed.
