TL;DR
Google’s current Singapore Daily Search Trends feed lists “singapore mrt backpack smoke” at 200+ approximate searches. That interest follows reporting of smoke from a power bank at Woodlands MRT station. The practical takeaway is not to hunt for a label that does not exist: Singapore’s Consumer Product Safety Office says power banks are not CPSO- or CCS-approved and are not issued the SAFETY Mark. Its advice is to buy from reputable or authorised sellers, look for sensible protection features and local support, and stop using a unit showing warning signs such as excessive heat, swelling, odour, damage, leakage or colour change.

What the Woodlands reports establish — and what they do not

Independent reporting by Mothership and competitor coverage by AsiaOne both say a power bank emitted smoke at Woodlands MRT station on 20 July, that staff responded and that trains bypassed the station for about 20 minutes. AsiaOne reported that the cause was under investigation. The two reports differ on whether there was a minor injury, so this article does not make an injury claim.

One incident cannot diagnose every device, brand or charging setup. It does, however, make the official consumer-safety checks worth reading carefully rather than turning a single incident into a general verdict about all power banks.

The SAFETY Mark is the wrong test for a power bank

The Consumer Product Safety Office’s published guidance makes a point that is easy to miss in a hurried shop search: there is no “CPSO approved” or “CCS approved” power bank, and power banks are not issued the SAFETY Mark. Do not treat a listing that uses those phrases as proof of official approval.

That does not mean there are no rules. The office says products sold in Singapore must comply with the Consumer Protection (Consumer Goods Safety Requirements) Regulations, with suppliers responsible for compliance. The better consumer question is whether the device and seller give you the checks the guidance actually names.

What to check before you buy

  • Seller: buy from reputable retailers or authorised sellers, not an anonymous listing that makes an approval claim it cannot substantiate.
  • Protection: look for protection against overcharging, short circuits and heat, plus a full-charge automatic power-off function.
  • Support: check that a charge indicator, local warranty and servicing are available.
  • Basics: use the original cable supplied with the unit where possible, keep the ports clear of metal objects and store it in a cool, dry place.

These are official pointers, not a promise that a particular model is risk-free. They are a more defensible shopping checklist than an invented approval badge.

Signs that mean stop using it

The official page is unusually clear about the warning signs: excessive heat, swelling or deformation, unusual odours, damage to the casing or cord, leakage and colour change. If a power bank shows any of them, stop using it. The office also says not to repair a damaged unit yourself and to dispose of or recycle it according to local requirements.

For charging, it advises against leaving a power bank charging on beds, sofas, blankets or other flammable surfaces, and against exceeding the recommended charging time. Those are ordinary habits, but they are more actionable than simply telling commuters to be frightened of a battery pack.

A commuter-sized conclusion

If smoke or another safety concern occurs in a station, staff directions and emergency services are the authority to follow. The reporting on Woodlands describes station staff responding to the incident; it is not a substitute for a live incident instruction. For day-to-day ownership, use the regulator’s specific checks, pay attention to warning signs and do not claim that a power bank is “SAFETY Mark approved”.

Frequently Asked Questions

Do power banks in Singapore carry the SAFETY Mark?

No. The Consumer Product Safety Office says that power banks are not issued the SAFETY Mark and should not be described as CPSO- or CCS-approved.

What should I look for when buying a power bank?

Buy from reputable retailers or authorised sellers. The official guidance points to protection against overcharging, short circuits and heat, full-charge automatic power-off, a charge indicator, and local warranty and servicing.

When should I stop using a power bank?

Stop using it if there is excessive heat, swelling or deformation, an unusual odour, casing or cord damage, leakage or colour change. Do not repair a damaged unit yourself.

What was reported at Woodlands MRT?

Mothership and AsiaOne reported smoke from a power bank on 20 July, staff response and trains bypassing Woodlands for about 20 minutes. AsiaOne said the cause was under investigation. The two reports differ on injury detail, so this article does not make an injury claim.

Does an online listing saying “CPSO approved” prove a power bank is safe?

No. The official guidance says there is no CPSO- or CCS-approved power bank. Use the regulator’s stated seller, feature and support checks instead, and be wary of an unqualified approval claim.
