Here’s a short, practical guide plus recommended fast-charging portable chargers (power banks) available to Australians right now — with what they’re good for and why to pick them.

What to look for in a fast power bank

• Output power (W): USB‑C PD / PD 3.1 and high wattage (60W–140W+) lets you fast‑charge modern phones, tablets and even laptops. Higher W = faster charging for big devices. (TechRadar.com)
• Ports: Multiple USB‑C ports (some with different max W) vs USB‑A. Useful if you want to charge phone + laptop simultaneously. (amazon.com.au)
• Capacity vs airline rules: mAh gives capacity but airlines limit watt‑hours (Wh). Many high‑capacity banks fall under the 100 Wh limit (carry‑on OK) but anything 100–160 Wh needs airline approval; >160 Wh is generally forbidden. Convert: (V × mAh) / 1000 = Wh. Always check the Wh printed on the product. (casa.gov.au)
• Recharge speed: Look for high input PD rating (e.g., 65W–140W) to recharge the bank quickly. (TechRadar.com)
• Safety & certifications: Choose reputable brands with protections (temperature/cell monitoring, short‑circuit protection, UN38.3) and local compliance. (casa.gov.au)
• Size/weight and real‑world output efficiency: higher capacity + higher watt output tends to weigh more; check reviews for real delivered wattage and heat. (TechRadar.com)

Top fast‑charging power banks (use-case + why) — sources included

• Anker 737 Power Bank (PowerCore 24K) — best high‑power laptop + phone bank

  • 24,000 mAh, up to 140W USB‑C PD (two USB‑C + USB‑A), fast self‑recharge; excellent for charging 16" laptops and phones quickly. Good balance of capacity and very high output. (Anker.com)

• Anker Prime (examples: 12,000 mAh 130W / other Anker high‑W models) — best compact, very high output

  • Extremely portable while still supporting 100W+ PD for laptops; smart display / ActiveShield safety on newer models. Good if you want laptop power in a smaller pack. (Anker.com)

• ZMI No.20 (or ZMI 25,000 mAh 100W models) — best overall/value for Australians

  • High capacity (≈25,000 mAh) with 100W output, good balance of capacity, price and charging speed — highlighted in Australian buying guides. (TechRadar.com)

• UGREEN 100W (20,000 mAh) / UGREEN high‑output models — best for multi‑device charging

  • 100W USB‑C + additional ports; fast recharge of the bank itself (high input PD), compact for its power. Good for charging a laptop + phone/tablet at once. (Available on Amazon AU listings). (amazon.com.au)

• Zendure SuperTank / SuperTank Pro — best for power‑users & multiple high‑W outputs

  • Very high capacity and multiple high‑W USB‑C ports (some variants 100W per port), OLED info displays — great for users with several laptops/devices. (thetimes.com.au)

• Anker 633 Magnetic Battery (or MagSafe‑compatible banks) — best for iPhone with MagSafe wireless fast charging

  • Compact, MagSafe alignment for iPhone 12/13/14/15/16 series; decent wired PD output too. Good if you prefer wireless convenience. (theverge.com)

Quick buying checklist (one‑line each)

• If you need to fast‑charge a laptop: choose PD 100W+ (or PD 65W+ if smaller laptop). Look at Anker 737 / Prime / Zendure SuperTank. (TechRadar.com)
• If you mainly charge phones/tablets: 10,000–20,000 mAh with 20–100W PD and at least one USB‑C is fine (UGREEN, ZMI, Baseus, INIU). (TechRadar.com)
• If you want MagSafe wireless: get a MagSafe‑compatible power bank to keep alignment and speed; check Apple‑compatible specs. (theverge.com)
• If you fly: keep the bank in carry‑on, check Wh rating — ≤100 Wh: generally OK; 100–160 Wh: airline approval required; >160 Wh: usually not allowed. Confirm with your airline before travel. (casa.gov.au)

Where to buy in Australia

• Official brand stores and local retailers (Anker AU site, Amazon Australia, major electronics retailers) — buying locally simplifies warranty & compliance. Check recent local buying guides for best current models and prices. (Anker.com)

If you want, I can:

• Suggest the best single model for your exact needs (phone only / laptop / travel weight limits) and a link to local Australian sellers; or
• Compare two models you’re choosing between (capacity, real watt output, recharge time, weight, price) with citations.
