Flying with a power bank? Clear rules apply. The good news: virtually every everyday power bank is allowed. The important part: only if you pack it right. Here is what to know before you zip up your bag.
Rule one: always in your hand luggage
Lithium batteries, and therefore power banks, are banned from checked luggage worldwide. The reason is safety: an overheating battery in the hold is invisible and unreachable. In the cabin it is not. So keep your power bank in your hand luggage or jacket pocket.
Rule two: the watt-hour limit (Wh)
Airlines measure in watt-hours, not mAh. Converting is simple:
Wh = mAh × 3.7 ÷ 1000
| Power bank | Capacity | Watt-hours | Allowed on board? |
|---|---|---|---|
| SYVOX Solar 10K | 10,000 mAh | ±37 Wh | Yes, no approval needed |
| SYVOX Magnetic 20K | 20,000 mAh | ±74 Wh | Yes, no approval needed |
The international rule of thumb: up to 100 Wh (roughly 27,000 mAh) travels freely. Between 100 and 160 Wh you need advance airline approval; above that it is prohibited. Both SYVOX power banks stay well below the limit.
Increasingly common: extra rules on board
Several airlines have tightened their rules in recent years. Common additions: keep your power bank within reach (not in the overhead bin), and some airlines do not allow charging devices from a power bank during the flight. Rules differ per airline, so check your airline's website before departure.
Smart packing: practical tips
- Charge your power bank at home: airport sockets are scarce.
- Protect the USB ports from metal objects (keys, coins) in the same bag.
- Bring the right cable, or pick a power bank with built-in cables, which you cannot forget.
Frequently asked questions
How many power banks can I bring?
Most airlines allow several per person as long as each stays under 100 Wh; some set a maximum count. Check your airline if in doubt.
Does my power bank go through the scanner?
Yes: like a laptop or tablet, security may ask you to place it separately in the tray. A readable capacity label on the casing avoids discussion.
Is a solar power bank allowed too?
Yes: aviation rules only count the battery capacity, not the solar panel. The Solar 10K sits comfortably within the standard limit at ±37 Wh.
