A must-read for flying in 2025! New rules for carrying mobile phone chargers – check them before you travel

Your phone is a lifeline during travel—it stores your boarding pass, navigation maps, and keeps you connected. Running out of battery mid-flight is one of the worst scenarios.

The good news is: yes, you can bring your phone charger on the plane. But to get through security smoothly, there are some important details you need to know.

Quick Guide: Different Rules for Two Types of Chargers

Wall Chargers: Can be carried in either carry-on or checked luggage—no worries.

Portable Chargers (Power Banks): Must be placed in carry-on luggage only—strictly prohibited in checked bags.

Why the difference? It all comes down to safety. Power banks contain lithium-ion batteries, which could overheat and pose risks in the cargo hold. When kept in the cabin, crew members can respond quickly to any issues.

Battery Capacity Limit: Remember the Key Number—100Wh

Airport security strictly limits the battery capacity of power banks: it must not exceed 100 watt-hours (Wh). This number is usually printed on the label of the power bank.

If your charger only shows mAh (milliampere-hours), use this formula to convert:
Wh = (mAh × Voltage) / 1000
(Most power banks have a voltage of 3.7V)

Examples:

10,000mAh power bank → (10,000 × 3.7) / 1000 = 37Wh (✅ Compliant)

30,000mAh power bank → (30,000 × 3.7) / 1000 = 111Wh (❌ Exceeds limit!)

Pro Tip: Power banks below 27,000mAh generally meet the requirements. If you’re unsure, check the product specifications in advance or contact the airline.

In-Flight Usage Guide: When You Can and Can’t Use Them

Power Banks: Can be used during the flight but must be turned off during takeoff, landing, and turbulence.

Wall Chargers: Can only be used if your seat is equipped with a power outlet.

Expert Advice: Make the most of charging facilities at the airport while waiting. Most airports have charging stations—topping up your devices before boarding is the safest strategy.

Airline Policies: Details Make a Difference

Although the TSA and FAA set basic rules, individual airlines may have additional requirements. Some may allow power banks up to 160Wh (with prior approval), while international flights often have stricter regulations.

Best Practice: Before your trip, check the “Baggage” or “Electronics” section on the airline’s website. If in doubt, calling customer service is the most reliable way to get accurate information.

Security Check Tips

Place chargers in an easily accessible spot for inspection.

Ensure the capacity label on your power bank is clearly visible.

Remember the basic rule: “Power banks in carry-on, wall chargers anywhere.”

With a little preparation, you can keep your devices charged, pass through security smoothly, and enjoy a worry-free flight.
