Frequently Asked Questions
What does mAh mean on a power bank?
mAh (milliamp hours) is the capacity — how much charge a power bank holds. A typical phone battery is 3,000-4,500mAh. A 10,000mAh bank provides roughly 2-2.5 full charges after accounting for inefficiency. Expect about 60-70% of the rated mAh in real-world use.
Can I bring a power bank on a plane?
Yes — power banks up to 27,000mAh (100Wh) like the Anker PowerCore III Elite 25600 are allowed in carry-on luggage. Power banks are NEVER allowed in checked baggage. Always keep them in your carry-on.
