Introduction
The Hidden Dangers of Power Banks
Power banks have become everyday essentials in Malaysia, especially for those always on the move. But behind the convenience lies a serious risk: power bank explosions. Without proper electrical safety checks, your portable charger could catch fire or explode — putting your safety and property in danger.
Why Do Power Banks Explode?
1. Poor Quality Batteries
Cheap or fake power banks often use low-grade lithium-ion batteries that are highly unstable. These batteries degrade quickly and pose explosion risks, especially in Malaysia’s hot weather.
2. Overcharging & Overheating
Leaving your power bank plugged in overnight or charging under direct sunlight causes overheating, which may result in thermal runaway — a chain reaction leading to fire or explosion.
3. Manufacturing Defects
Some units come with internal short circuits or lack safety cut-off features. Without overcharge protection circuits, the risk of failure increases significantly.
Common Warning Signs of a Faulty Power Bank
Swollen casing
Unusual heat even when not in use
Burning smell or strange noises
Slow charging or power failure
If your power bank displays any of these signs, stop using it immediately and consult a professional.
How to Do Electrical Safety Checks at Home
🔍 Visual Inspection
Check for dents, bulges, or leaks. If the casing looks warped, that’s a red flag.
⚡ Use the Right Charger
Always use the original or compatible charger with appropriate voltage and amperage. Never mix brands.
🚫 Avoid Knock-off Brands
Prioritize SIRIM-certified or TNB-compliant power banks to ensure they meet Malaysian electrical safety standards.
Best Practices to Prevent Power Bank Explosions
Don’t leave your power bank charging unattended
Store in a cool, dry place
Avoid exposure to sunlight or heat
Replace any power bank older than 2 years
Use power banks with built-in safety features like overcharge protection
📍 Real-Life Case in Malaysia:Woman suffers burns, room damaged after power bank explodes while charging
In November 2025, a woman in Selangor suffered burns on her right arm after her power bank exploded while charging in her room. The device, which she had purchased for around RM70 to RM100, burst into flames when it was about 70% charged, causing minor injuries and damaging nearby items including her printer, gaming chair, and wall.
She suspected the explosion was due to prolonged use or Malaysia’s hot weather, reminding others to avoid overcharging and never leave power banks unattended or charging on flammable surfaces. The incident highlights the importance of electrical safety checks and choosing quality, certified devices to prevent fire hazards.
Did You Know?
Malaysia recorded 50+ electrical fire incidents in 2025 linked to faulty portable chargers and power banks.
TNB advises users to never use damaged power cables or devices showing signs of overheating.
Using counterfeit power banks increases explosion risk by up to 70%, according to Energy Commission Malaysia.
Conclusion
Stay Charged, Stay Safe
While power banks are convenient, they’re not without risks. Stay vigilant and follow proper electrical safety practices to prevent accidents. Better yet, let a certified electrician in KL or Selangor conduct a full safety inspection of your charging stations, outlets, and devices.
Frequently Asked Questions
Q1: Can a power bank explode while not in use?
Yes, especially if the internal battery is faulty or swollen. Always store in a cool place and inspect regularly.
Q2: How do I know if my power bank is safe?
Check for SIRIM approval, brand reputation, and built-in safety certifications such as overcharge, overcurrent, and short circuit protection.
Q3: Is it safe to charge overnight?
Not recommended. Overcharging is one of the leading causes of power bank explosions.
