If you travel, you need your phone. Your phone helps you find places, talk to people, and take pictures. But your phone’s battery can run out. A portable power bank helps keep your phone charged.
Many people ask: Can you bring a power bank on a plane? What do the TSA and airlines say about power banks in carry-ons? What is the best power bank for travel? This guide gives answers. It also tells you about the 3-in-1 Power Bank Portable Charger Hand Warmer Mirror—a good choice for travel.
Are Power Banks Allowed in Carry-On Bags?

Yes, you can bring power banks in your carry-on, but there are rules. The TSA and FAA say power banks with lithium-ion batteries must be in carry-on bags, not checked bags. This is because lithium-ion batteries can overheat. If they are in the cabin, any problem can be fixed fast.
Rules for Carrying Power Banks on a Plane:
-
Put power banks in carry-on bags (not in checked bags).
-
The battery must be 100Wh or less to fly without airline approval.
-
Batteries 100Wh to 160Wh need airline approval.
-
Batteries over 160Wh are not allowed.
To check if your power bank is okay, look at its label or use this formula: mAh / 1000 × Voltage (V) = Wh
For example, a 10,000mAh power bank (3.7V) is:
10,000mAh / 1000 × 3.7V = 37Wh, so it is safe.
Why You Need a Power Bank for Travel
A portable charger is very useful when traveling.
