Here’s a short guide + ready recommendations for portable chargers (power banks) that support fast charging — grouped by use case so you can pick what fits you best.

How “fast charging” works (short)

• Fast wired charging is mostly delivered by USB Power Delivery (PD) and variants such as PPS (Programmable Power Supply) or Qualcomm Quick Charge. Newer PD versions (PD 3.1 / EPR) enable much higher wattages (well above the old 100 W limit), which matters if you want to fast-charge laptops as well as phones. (usb.org)

Air travel note (important)

• Airlines/FAA treat power banks as lithium batteries. Generally: ≤100 Wh allowed in carry‑on; 101–160 Wh allowed only with airline approval (limit: usually up to two), and >160 Wh is normally forbidden. Keep power banks in carry‑on, not checked luggage. Check your airline for any extra restrictions (some carriers now restrict in‑flight use or require power banks be visible while charging). (faa.gov)

Buying checklist (what to look for)

• Output wattage (30 W / 45 W / 65 W / 100 W+): match to device — phones usually top out at 18–45 W, modern laptops often need 45–100 W or more for full-speed charging. (wired.com)
• Port types: USB‑C PD (best universal), look for PPS if you have Samsung/other PPS‑enabled phones.
• Two‑way charging / recharge speed: check input wattage (e.g., 30 W, 60 W, 100 W) so the bank itself recharges quickly.
• Capacity: mAh is marketing — convert to Wh (mAh × 3.7V / 1000 = Wh) to check airline rules and realistic energy.
• Cables: use USB‑C cables rated for the wattage (5A / 100W or higher cables for 100W+).
• Real-world notes: expect ~60–90% usable energy due to conversion losses; smaller banks are more portable, larger ones last longer but may be heavier or approach airline Wh limits.

Recommended fast chargers (representative picks)

• Best compact fast bank (everyday carry): Anker Nano Power Bank — 10,000 mAh, 30 W USB‑C PD two‑way charging. Slim, quick for phones and small tablets. Good balance of size and speed. (anker.com)
• Magnetic wireless + fast wired (iPhone owners): Anker MagGo 10,000 mAh — MagSafe‑style magnetic wireless up to ~15 W and wired USB‑C up to 30 W; convenient for iPhone 12+ with magnetic alignment. (nypost.com)
• Mid-capacity laptop + phone: RAVPower PD Pioneer 20,000 mAh (60 W PD) — 60 W USB‑C PD output suitable for many laptops and fast phone charging; two ports for simultaneous charging. Good value option. (ravpower.com)
• High-capacity, high‑power (powerful laptop support): Zendure SuperTank Pro (≈26,800 mAh, 100 W USB‑C PD output, total output ~138 W) — charges laptops at near full speed, fast recharge, OLED readout and multiple ports (great for power users). (powerbank.zendure.com)
• Very high-output portable (multi‑device / desktop replacement): Anker 737 Power Bank (PowerCore 24K) — 24,000 mAh, high total output (up to ~140 W aggregate on some configurations), multiple ports for phones, tablets, and laptops. Good if you want one bank for everything. (anker.com)
• Ultra‑compact high-watt (pocket 45 W option): Iniu Pocket Rocket P50 — small 10,000 mAh bank offering up to 45 W output (PPS support), ideal if you want a true pocketable fast charger. (the-independent.com)

Short recommendation by need

• Just fast phone top‑ups and portability: Anker Nano or Iniu Pocket Rocket. (anker.com)
• Phone + occasional tablet / light laptop use: RAVPower 60 W (20,000 mAh). (ravpower.com)
• Heavy laptop use / multi‑device travel: Zendure SuperTank Pro or Anker 737 (100 W / 140 W class). (powerbank.zendure.com)
• iPhone with MagSafe convenience: Anker MagGo magnetic bank. (nypost.com)

Practical tips before you buy

• Match max output to your device (don’t buy 100 W if all you need is a 30 W phone bank).
• For 100 W charging you’ll need an appropriate 5 A USB‑C cable and a bank that explicitly lists 100 W PD (or PD 3.1 / EPR). (usb.org)
• If you fly, convert mAh→Wh and keep the bank in carry‑on; don’t assume larger bulk capacities are allowed—check airline rules first. (faa.gov)

If you want, I can:

• Give a short comparison table (size, weight, ports, price range) for any subset of the models above, or
• Find lowest current prices/where to buy specific models (I’ll need to look up retailers and deals).

Which of the above best matches what you want (pocket phone bank, laptop power, MagSafe, or ultra‑high capacity)?
