If you are going on a trip and want to know if you can bring your 2-in-1 Power Bank Hand Warmer on a flight, you are not alone. Air travel rules change often. You need to know what you can take in your carry-on or checked bag. This guide will help you understand the rules for rechargeable hand warmers and power banks.
TSA and Airline Rules

The Transportation Security Administration (TSA) and airlines have rules for devices with batteries. Since most rechargeable hand warmers, like the 2-in-1 Power Bank Hand Warmer, have lithium-ion batteries, you must follow the rules before packing.
Can You Bring Rechargeable Hand Warmers on a Plane?
The answer is yes, but there are rules.
TSA and airlines say:
-
Carry-on Bags: Allowed
- Checked Bags: Not Allowed
Rechargeable hand warmers have lithium-ion batteries. You must put them in your carry-on bag and not in checked luggage. This is because batteries can overheat or catch fire in the cargo area.
Power Bank Function: Any Extra Rules?
The 2-in-1 Power Bank Hand Warmer is also a charger, so it follows power bank rules. Most airlines let you bring power banks in your carry-on, but they have limits on battery size:
-
Less than 100Wh (Watt-hours): Allowed in carry-on.
-
100Wh - 160Wh: Allowed, but you may need permission from the airline.
-
Over 160Wh: Not allowed.
Most hand warmers, including the one from Eunoia Selects, are under 100Wh. This means they are safe to take.
How to Pack a Rechargeable Hand Warmer for a Flight

To avoid problems at security:
-
Put it in your carry-on – Do not put it in checked bags.
-
Turn it off – Make sure it is off before security checks.
-
Pack it separately – Take it out if security asks.
-
Know the battery size – Airlines might ask.
-
Use a protective pouch – A heat-resistant bag is a good idea.
