Good question — the best travel chargers balance power, size, and international usability. Below are quick buying tips plus 6 solid picks tailored for different travellers (phone-only, laptop users, multi-device families). I’ve included notes about airline rules and why each type matters.

What to look for

• GaN (gallium nitride): much smaller and cooler than older silicon chargers at the same wattage — ideal for travel. (androidauthority.com)
• USB-C PD (Power Delivery) and PD 3.1 where possible: lets phones, tablets and many laptops fast-charge from the same charger. Match charger wattage to device needs (20–30W phones, 45–100W laptops). (TechAdvisor.com)
• Multi-port with intelligent power distribution: lets you charge phone + laptop + earbuds from one outlet while sharing max power efficiently. (TechAdvisor.com)
• Interchangeable/prong adapters or world‑plug included: saves carrying plug adapters when moving between AU/UK/EU/US outlets. (TechAdvisor.com)
• Airline rules for power banks: carry-on only; most airlines restrict unapproved batteries over ~100 Wh (27,000 mAh ≈ 100 Wh) — check your airline for any exceptions/approval required. (TechRadar.com)

Top travel charger picks (shortlist)

1. Anker 737 (GaNPrime) / PowerCore 24K (high-capacity combo)

   • Why: Very high output (multi‑port, up to laptop-level power), large capacity power bank + GaN options in Anker line. Good if you need to charge laptops and multiple devices off-grid. Check Wh to ensure airline compliance. (Beta.au.Anker.com)

2. Anker 735 / 65W GaN charger (best all-round compact wall charger)

   • Why: Small, 65W USB‑C PD, multi‑port options, reliable and compact for a laptop + phone. Great for carry-on day-to-day travel. (Anker.com)

3. Razer USB‑C 130W GaN (best for power-hungry laptop users who still travel)

   • Why: Up to 130W, multiple ports and comes with international prongs — excellent if you need near-wall-speed laptop charging in multiple countries. Slightly bulkier but very powerful. (androidauthority.com)

4. Alogic Rapid Power 67W Multi‑Country GaN (best travel-ready wall charger)

   • Why: Designed for travel with interchangeable plugs for AU/UK/EU/US and three outputs — great size-to-power balance for tourists/business travellers. (TechAdvisor.com)

5. UGREEN / Satechi multiport GaN chargers (best compact multi‑port)

   • Why: UGREEN (Nexode) and Satechi make compact multi-port GaN chargers (100–145W options) that handle phone + tablet + laptop without needing multiple plugs. Useful for families/coworking. (theverge.com)

6. ZMI No.20 or similarly airline-friendly power bank (best power bank for Australian travellers)

   • Why: High-capacity but designed within airline rules for many models (TechRadar lists ZMI No.20 as a top pick in Australia). Great when you need many phone charges but still want to fly without approval. Always verify the model’s Wh rating before boarding. (TechRadar.com)

Quick packing checklist

• One GaN multiport wall charger (65–100W) for hotels/airports. (Anker.com)
• One airline‑approved power bank if you’ll be away from power for long stretches (≤100 Wh to avoid approvals). (TechRadar.com)
• Short USB‑C to USB‑C cable and a USB‑A to USB‑C/Lightning if needed; consider a built‑in‑cable power bank if you don’t want to carry cables. (Beta.au.Anker.com)
• Travel plug adapter (or charger with included swappable prongs). (TechAdvisor.com)

If you want, I can:

• Recommend the best single charger for your exact devices (tell me phone/laptop/tablet models), or
• Find current Australian retailers and prices for any of the models above.
