If you need to charge a MacBook Pro at full speed (140W), your options are usually expensive. The Anker 737 (PowerCore 24K) is the famous choice, but the INIU 140W has appeared as a challenger for nearly half the price.
Is the INIU too good to be true? Or is Anker charging a "brand tax"?

1. Build Quality & The Screen
- Anker 737: It feels like a dense, premium brick. The screen is bright, sharp, and uses an accelerometer to rotate the text. It feels "expensive."
- INIU 140W: It feels plastic. The screen is basic—it shows the numbers, but it’s not as fancy as Anker’s. However, it does the job perfectly fine.
2. Performance (The 140W Test)
We plugged both into a MacBook Pro 16".
- Anker: Hit 138W instantly and held it steady.
- INIU: Hit 135W and held it.
- The Difference: Anker handles heat slightly better. During a full discharge, the Anker stayed warm, while the INIU got noticeably hot to the touch.
3. The Capacity Lie?
- Anker: Rated at 24,000mAh. Real-world output efficiency is about 80% (standard).
- INIU: Rated at 25,000mAh. Real-world efficiency is closer to 75%.
- Result: You get roughly the same amount of actual charge from both.
The Verdict
Buy the Anker 737 if:
- You want the best build quality and heat management.
- You love the fancy rotating screen.
- You use it daily for work.
Buy the INIU 140W if:
- You want to save ~$40-$50.
- You only need high-speed charging occasionally (travel/flights).
- You don't care about "premium feel," just raw power.
