**Power Banks: Essential, But Are They Safe? What You Need to Know Before You Travel**

Many of us use a power bank every day to extend the battery life of our phones. They are simple to use and, whether you’re a heavy phone user or just want to make sure your device stays powered up, power banks can be indispensable. However, it’s important to be aware of the potential risks—some power banks can be dangerous, as they contain lithium-ion batteries.

**Recent Power Bank Recalls: A Wake-Up Call**

Back in June, one of the leading manufacturers of power banks and mobile accessories, Anker, was forced to recall certain power bank models over safety concerns. In July, Anker added more power banks to the list of recalled units due to potential hazards.

**Power Bank Explosion at Melbourne International Airport**

Just recently, there was a serious incident at Melbourne International Airport in Australia. A man in his 50s was injured when the power bank he was carrying in his pocket exploded while he was sitting in a Qantas Airlines business lounge. Firefighters responded quickly, but the man suffered minor burns to his legs and fingers.

The explosion caused panic at the busy airport. One witness posted on Reddit: “I heard screaming from the other side of the lounge… battery acid [was] flying everywhere. His jacket caught on fire. They evacuated us because the smoke and smell was so strong, but I really just hope the guy is okay.” Local news outlets report the power bank owner is now in stable condition at a hospital.

**Why Do Power Banks Explode? Understanding the Risks**

Power banks are powered by lithium-ion batteries, which, while generally safe, can be hazardous under certain conditions. A phenomenon called thermal runaway can occur without warning due to:

– Damage to the battery
– Overheating
– Exposure to water
– Overcharging
– Improper packing
– Manufacturing defects

When thermal runaway occurs, the battery can overheat, catch fire, or even explode.

**Airline Regulations: Don’t Get Caught Off Guard**

Because of these risks, airlines have strict rules about how you can transport and use power banks:

– **Carry-On Only:** All power banks powered by lithium batteries must be packed in carry-on bags or kept on your person. You cannot check them in with your luggage.
– **In-flight Charging Rules:** Some airlines—like Southwest Airlines in the U.S.—prohibit passengers from charging devices using a power bank if the power bank is hidden in a bag. Instead, the power bank must be in plain view, so the flight crew can quickly respond to any issues.
– **Check Individual Airline Policies:** Always review your airline’s website before flying to learn their specific policies regarding power banks and in-flight charging.

**How to Spot a Dangerous Power Bank: Warning Signs**

It’s important to regularly check your power bank for any signs of trouble. Here are warning signs your power bank may be unsafe:

– **Swelling or Bulging:** This is a serious warning sign and indicates a high risk of fire. Stop using the power bank immediately.
– **Excessive Heat:** If it becomes too hot to hold while charging or using, it may have an internal fault or short circuit. Discontinue use and safely dispose of it.
– **Unusual Odor:** Any strange smell could indicate an internal failure or leak. Do not use the power bank.
– **Visible Damage:** Cracks, gaps, deformation, or warping mean the casing has been compromised and the device could short circuit. Do not use it.
– **Leaking Liquid:** Any fluid coming from your power bank is hazardous. Stop using it immediately.

**Buy Safe: Stick to Reputable Brands**

While you can find power banks for sale almost anywhere, your safest option is to purchase from major, trusted manufacturers like Belkin, Mophie—and yes, even Anker (despite their recent recall, they maintain a generally good reputation for safety).

**Final Thoughts**

Power banks are a modern necessity, but it’s crucial to be aware of the potential risks and follow safety guidelines—especially when flying. Regularly inspect your power bank, follow airline regulations, and always purchase from reputable brands to keep yourself and others safe.

**Stay informed, and safe travels!**
