An electronics engineer in Iloilo City pointed out that the explosion of a power bank in an airport in the Province of Capiz may have been due to overcharging.
“Possibly, naka-experience ng overcharging ang device, kaunti lang na trigger lumagpas na siya at that point. Akala mo, walang effect ang pagkabangga o pagkahulog or nag-overcharge pero yun pala, unti-unti siyang nag-ko-contribute to the point na hindi na kaya at iyon ang nag-trigger,” explained Engr. Marvin de Pedro, instructor at the Electronics Engineering Department of Iloilo Science and Technology University.
De Pedro advised the public to take precaution in handling power banks from falling or other forms of damages to avoid malfunctions.
“Avoid ang excessive na impact or possible na dislocation ng mga parts niya kasi posible na kaunting mis-alignment lang, maka-cause ng short circuit,” de Pedro said.
More stringent security screening at the Roxas Airport has been implemented following the explosion of a power bank on June 24, 2025.
A video showed how a power bank sparked and exploded at the Initial Security Screening Checkpoint in Roxas Airport.
According to airport police investigation, the incident happened past 6 a.m.
The power bank is owned by a Manila-bound female passenger.
The power bank was detected by a scanner kept in the hand-carry baggage of the woman.
Security personnel ordered the woman to take the power bank out of her bag.
It was found out that the power bank exceeded the 30,000 milliampere-hour-and-below allowed in flights. The woman brought a 72,000 mAh power bank.
“Ang pasahero, dinetach niya ang mga battery sa kanyang power bank JC. Nang tinanggal na niya at ipinakita na lithium ion ang kanyang battery, sinabihan siya na hindi pwede. Nang ibinalik na niya ang battery, doon na nag-short circuit at nag-spark at umusok,” said Lt. Jose Dexter Paulin, officer in charge of Roxas Airport Police Station.
No one was reported injured in the incident.
According to the airport police, the passenger first refused to hand over to the authorities the power bank, citing that she was allowed to bring it from Manila to Roxas City.
Further, it was learned that despite the incident, the woman was allowed to take the flight back to Manila.
