■ The catch — co-equal billing, always
It weighs 22 oz. That is 632g living in your bag, and at 86.4Wh it actually stores less energy per gram than the Anker Prime 26K (99.75Wh, 624g). Its 140W ceiling is wasted on a phone, which caps around 27W. This is a bag bank for people who charge a laptop — nothing about it is pocketable.

Traps — this verdict avoids
Why the Anker 737 PowerCore 24K is right for you
It avoids every trap below — and for anyone, under $150, it is the pick because it delivers:
The 100Wh wall
Airlines regulate watt-hours, not mAh. 100Wh (~27,000mAh) is the carry-on ceiling, 101-160Wh needs explicit airline approval and is usually refused, and power banks are carry-on only, never checked. IATA's 31 March 2026 operator guidance also tells airlines to stop in-flight use, and US carriers now cap spare batteries — American at 4, Delta at 20.
mAh is not what you get
A cell is rated at 3.7V nominal; your phone charges at 5V. Expect 60-75% real-world efficiency after conversion losses — a 10,000mAh bank realistically delivers 6,000-7,500mAh to a phone, not 10,000.
Check the A-number
The CPSC recalled about 481,000 Anker power banks (A1647, A1652, A1257, A1681, A1689) on 18 September 2025 after 33 fire and explosion reports. None of the models on this page are on that list — but the model number is printed on the unit itself, and the old bank in your drawer might be.
