For travel, the Nitecore NB10000 Gen 3 is the sweet spot: 10,000 mAh at just 5.3 ounces, well within airline limits. Bring the Anker 737 instead if you need to charge a laptop on the road.

Questions, answered
What is the airline limit for power banks?
Most airlines follow the 100 Wh rule: banks up to 100 Wh fly in carry-on with no approval needed. From 100 to 160 Wh you typically need airline permission, and above 160 Wh is prohibited. Power banks are never allowed in checked baggage. Always verify with your specific airline.
How do I find the Wh rating of my power bank?
It is usually printed on the bank itself, near the capacity marking. If only mAh is printed, divide mAh by 1000 and multiply by the nominal voltage (usually 3.7 V for lithium banks). When in doubt, carry the bank's spec sheet or a photo of its label.
Should I bring one big bank or two small ones?
One bank in the 10,000 to 20,000 mAh range suits most trips and keeps things simple. Two smaller banks make sense for group travel or as a backup, but every extra bank is extra weight and another device to keep charged.
