Airline safety tips
Carry power banks in your carry-on, not checked luggage. Check the watt-hour rating printed on the device. Some airlines restrict using power banks during flight, so check your airline’s current rules.
What to check before you buy
- Confirm your laptop supports USB-C charging.
- Check watt-hour rating against airline rules.
- Look for a display that shows remaining charge.
What to skip
Common mistake: buying a high-capacity phone power bank with only 18W to 30W output. It will barely charge a laptop.
When to buy
Power banks are often discounted during Prime events and Black Friday.
