The Anker 737 (PowerCore 24K) was the first power bank to make "Charging Screens" cool.
Now that the "Prime" series is out, the 737 has seen massive price drops. We revisited this legend to see if it’s still worth your money.

1. The Speed (140W Bi-Directional)
This is why the 737 is legendary.
- Output: It charges a laptop at 140W.
- Input: It recharges itself at 140W. If you have a fast wall charger, you can refill this massive battery from 0% to 100% in just 52 minutes.
2. Build Quality
It feels like a tank. The "Prime" series uses glossy plastic that scratches easily. The 737 uses a textured matte finish that is much more durable.
- The Screen: It has an accelerometer! The text rotates depending on how you hold it. It’s a small detail, but it feels premium.
3. What you miss (vs. Prime)
- No App: You can’t find it with Bluetooth.
- No Dock: It doesn’t work with the wireless charging base.
- Size: It is slightly taller and heavier than the Prime 20K.
The Verdict
If you don't care about Bluetooth apps, BUY THIS. You get flagship performance (140W) for a mid-range price. It is the best value power bank Anker has ever made.
