Can you take a power bank on Taiwan Railway (TRA) in 2026?

Can you carry a power bank on a TRA train? Is there a capacity limit? Can you use it on board? Here are the current rules, the safety advice and the common questions.

📌 The three-minute version

  • ✅ TRA currently allows power banks on trains.
  • ✅ No 100Wh limit like air travel has been announced.
  • ✅ You can use one, with reasonable care.
  • ⚠️ Do not charge it inside a bag.
  • ⚠️ If it swells, smokes, smells or gets unusually hot, stop and tell the train crew.

🚆 Can you bring a power bank on TRA?

Yes.

Taiwan Railway Corporation does not prohibit passengers from carrying power banks, and has announced no capacity limit for ordinary passengers. Commuting, travelling home or on a long journey, you can keep one with you.

After a number of lithium battery and power bank fires in Taiwan and abroad, TRA has stepped up safety messaging: avoid heat, impact and crushing while using one on board, and watch for unusual heat or swelling.

📌 In short

  • Power banks may be carried on TRA.
  • No capacity limit has been announced.
  • They can be used normally, following basic safety practice.
  • If anything looks wrong, stop and inform the crew.

🔋 Is there a capacity limit?

No. TRA has not announced a capacity limit for ordinary passengers, so the 100Wh and 160Wh air transport thresholds do not apply.

Any power bank sold legally in Taiwan and in normal working order can travel with you. Still, avoid products of unknown origin, visibly damaged units, or batteries that have swollen.

💡 A reminder

  • No announced 100Wh limit.
  • No restriction on carrying more than one.
  • Safety-certified products are still recommended.
  • If it has been dropped, soaked or has swollen, stop using it.

📱 Can you use one on board?

Yes.

TRA does not prohibit using a power bank on the train to charge a phone, tablet or other device.

Because it is a lithium battery product, charging generates heat, so keep it ventilated — not under a blanket, inside a coat, or in a backpack where heat builds up.

If you notice unusual heat, smoke, an odd smell or swelling while charging, stop immediately and ask the conductor or station staff for help.

✅ Safe use

  • Keep the power bank where you can see it.
  • Do not charge it inside a bag or suitcase.
  • Avoid impact, drops and heavy pressure.
  • Avoid direct sun and high heat.
  • If it smokes, catches fire or smells, stop, move it away from anything flammable, and tell the crew.
