■ The catch — co-equal billing, always
It's a 21-ounce brick. At 25,000 mAh and over 1.3 lb it's the heaviest bank here, and overkill if you only ever charge a phone — the card even sends laptop-primary buyers to its dedicated laptop-bank guide.

Traps — this verdict avoids
Why the Anker Laptop Bank 25K is right for you
It avoids every trap below — and for just me, under $150, it is the pick because it delivers:
Phantom capacity
Rated mAh is measured at the cell's 3.7V — your phone charges at 5V, so you actually get only 65-70%. A "10,000 mAh" bank delivers about 6,500 mAh of real charge.
Flight-banned capacity
Power banks over 100 Wh (~27,000 mAh) need airline approval, and anything over 160 Wh is banned from flights entirely. We keep travel picks under the line.
Wireless that isn't fast
Qi2.2 25W only works on an iPhone 16 Pro+/17 or Pixel 10 Pro — pair it with any older iPhone and it silently falls back to 15W, no faster than a cheap pad.
