In my opinion, this only provides a small boost of a few minutes faster with the S23/24 Ultra. The normal 25 watt fast charger is definitely enough to charge your mobile quickly. Other companies are much further ahead.

I can't answer that because I bought it for my Flip 3. But I can say that the cable is thicker and therefore more stable. The mesh part is also more robust. I would buy it again.

For my part, by choosing a 45W charger, I'm very happy with it ... it's very fast in terms of charging time.
On my S23 ultra 5000 mAh.
Your 3880 mAh battery ... it's going to be ultra fast.

Yes it's good.
