Build quality & everyday use

What carries the Anker 737 (PowerCore 24K) in daily use: 140W PD 3.1 (charges a MacBook Pro 16 at full speed, unique in the class) and OLED display (remaining capacity, battery health and live watts per port). The weaknesses need to be stated honestly: heavy (630 g), so not trouser-pocket size.

If you set the device up to save space, make sure it stands on a stable, level surface with some air around it. This protects the mechanics and electronics in continuous use.

“Anker 737 Power Bank 24,000 mAh 140W: 140W PD 3.1 and OLED display. In return you accept the weight (630 g). At 9.1/10 a clear recommendation from €75.”

Frequently asked questions about the Anker 737 (PowerCore 24K)

Does the Anker 737 really fully charge a MacBook Pro 16?
Yes. With 140 W PD 3.1 it charges the MacBook Pro 16″ (which accepts up to 140 W) at full speed, from 0 to about 50% in 30 minutes. For the MacBook Air, iPad Pro and all smartphones the output is more than enough. Important: use a PD 3.1 capable USB-C cable.
Can I take the Anker 737 on a plane?
Yes. At 86.4 Wh it is below the 100 Wh limit of the IATA rule and is allowed in hand luggage. Power banks are generally prohibited in checked baggage.
What does the OLED display show?
Remaining capacity in percent, current input/output power in watts per port, estimated remaining charge time and the battery health status. That is considerably more informative than the usual 4-LED indicators.
How many smartphone charges does the 737 manage?
At 24,000 mAh and ~70% efficiency: an iPhone 16 (approx. 3,500 mAh) gets about 4.8× full charges. A Samsung Galaxy S24 (4,000 mAh) gets approx. 4.2× full charges.
How quickly does the 737 itself recharge?
With a 140 W USB-C charger, fully charged in about 60 minutes. With a normal 30 W charger approx. 3 to 4 hours. Bidirectional 140W charging is a clear advantage over competitors with slow input power.
Is the 737 worth it compared with the INIU P63?
The 737 has 140W (vs. 100W INIU), an OLED display and the Anker brand, but costs more. The INIU P63 is cheaper, lighter (392 g vs. 630 g) and is enough for most laptops. For the MacBook Pro 16 or maximum charging speed: 737. For value for money: INIU P63.
