High-capacity power bank explodes at Philippine airport: What happened next

Manila, Philippines: A high-capacity power bank exploded at Roxas Airport in Capiz province on Tuesday, prompting renewed warnings on the dangers of carrying oversized lithium-ion batteries aboard aircraft. 

Fortunately, no injuries or major damage were reported, according to the Civil Aviation Authority of the Philippines (CAAP).

In a statement, CAAP said the incident occurred during routine screening of a Manila-bound passenger’s baggage.

Security personnel flagged the item — a 72,000 milliampere-hour (mAh) power bank — after determining that it exceeded aviation safety limits. 

Airlines and aviation regulators typically cap allowable power banks at 160 watt-hours (Wh) for carry-on, a standard set by the International Civil Aviation Organisation (ICAO). 

The unit in question was significantly over that limit.

The passenger initially argued that the device had been allowed on her inbound flight, but eventually consented to hand the power bank to a companion waiting outside the terminal. 

However, while arrangements were being made, the device suddenly sparked and caught fire on the inspection table.

An alert security guard quickly discharged a fire extinguisher to suppress the flames. Moments later, the power bank exploded. No injuries were reported, and airport operations continued with minimal disruption. 

CAAP praised the “swift and professional” response of the security and screening personnel, which likely prevented a more dangerous situation.

Incidents like this highlight the growing concern over high-capacity lithium-ion batteries, particularly in air travel.

Power banks, laptops, and smartphones rely on these energy-dense cells, which can become unstable if damaged, overcharged, exposed to heat, or manufactured poorly.

A 72,000 mAh power bank — likely intended for camping or emergency backup — typically exceeds safe limits for commercial flights. 

When calculated for watt-hours, the device likely surpassed 266 Wh, well beyond the allowed threshold. 

For comparison:

Moreover, lithium battery fires are difficult to extinguish because they can experience thermal runaway, a chain reaction that causes the battery to overheat and explode. 

Extinguishers may suppress flames temporarily but not prevent detonation.

Globally, the aviation industry has recorded an increase in battery-related incidents. 

The US Federal Aviation Administration (FAA) reported over 60 battery-related fires on aircraft in 2023 alone, many linked to e-cigarettes, power banks, or laptops.

In the Philippines, CAAP regularly reminds the public to check the specifications of their power banks before traveling.

The agency also urging travellers to review airline guidelines and avoid using unbranded or uncertified battery products.

The Roxas Airport incident ended without tragedy — but it’s a powerful reminder that even small electronics can pose serious risks if mishandled.
