5,000 or 10,000 mAh?
Only about 60–70% of a power bank’s rating reaches your phone, because the cells charge at a higher voltage and some energy is lost as heat. A 10,000mAh bank gives roughly two full charges to a 3,000mAh phone and one and a half to a 4,000mAh phone. A 5,000mAh bank gives about two-thirds of a charge to a 5,000mAh phone — enough to get home. See the full maths.

Questions people ask
How many times can a 10,000mAh power bank charge my phone?
About 60–70% of the rated capacity reaches the phone, so a 10,000mAh bank gives roughly 2 full charges to a 3,000mAh phone and about 1.2–1.4 to a 5,000mAh phone.
Can I take a power bank on a flight?
A 10,000mAh power bank holds about 37Wh, under the 100Wh limit airlines generally allow. Power banks must go in your hand luggage, never in checked bags.
What does 22.5W fast charging mean?
A 22.5W power bank refills a phone that supports fast charging much quicker. Phones without fast charging still charge at their normal speed. The CDB-16, CDB-17, CDB-23 and CDB-24 are 22.5W.
Which power bank doesn't need a cable?
The CDB-21 and CDB-13 have four built-in cables, the CDB-23 three and the CDB-16 and CDB-17 two. The CDB-24 also has a fold-out wall plug, so it recharges without a charger.
