The multi-device pick — and the only one no independent lab has measured.

Anker 737 Power Bank (PowerCore 24K)
The default laptop pick.

Anker Laptop Power Bank 25K 165W (A1695)
The cable-free travel pick.
Specs & pros/cons

- 100W per USB-C; the 165W total needs two devices and more than about 78% charge
- Best Batteries measured 96W to one device; about 74Wh of the 90Wh delivered
- Self-recharge peaks near 90–92W; 18-month warranty
Pros:
- No cable to pack; the display shows per-port watts, temperature, cycles and health
Cons:
- A 2026 heise online report describes failed built-in cables, including one reported to have damaged a MacBook Pro mainboard; Anker is investigating, with no recall
- The unit is glued shut and the cables are not replaceable, so a cable failure is effectively terminal

Cons:
- Owners report units arriving dead, boot-looping or throwing E107 undervoltage errors
The wattage on the box is not the wattage you get
Across these six, the headline number is a ceiling, not a promise. The Blade’s 100W is a nine-minute burst. The GP12’s 145W is unverified. The A1695’s 165W needs two devices and a nearly full pack. The 737’s 140W is split across every port. The A1340’s 250W is a 24-minute sprint.
Who should buy which
- One fast laptop and a useful screen: the Anker 737.
- Laptop, tablet and phone at once: the A1340, if you can find it new.
- Four devices on a budget, spec sheet taken on faith: the EnerGeek GP12.
