Also reviews mention that the charger gets really hot with 4 devices. Plus most reviews are for Vine Free product.
Given all of this and the fact the charger doesn't show any ETL/UL certification, I'd not recommend this deal.
Used my iphone 15 usb C, and the highest it got was 22w by itself. Used it to together with an ipad 10th gen usb C and it also max out 22W combined.
One more combination I used was my iphone 15 usb C and fire tablet usb A, and it got to 33w combined. Pics for reference:

My math:
- USB-A Port Consumption: If, as claimed, it supplies 3.1A at 5V that uses 15.5W (3.1 x 5) for one of the USB-A ports. So if both USB-A ports are used, they'd consume 31W together.
- Remaining Power: This would leave only 9W (40 - 31) for the two USB-C ports to share. Much less that 20W each. It seems like you'd need to only use the USB-C ports to get the 40W.
It seems the charger is optimized for scenarios where fewer ports are in use, especially if fast charging is a priority. I think using all 4 ports might not be a great option unless you use this as an overnight/bedside charger.Our community has rated this post as helpful. If you agree, why not thank PowerfulName4771

It works fine. But I can hear it emit a noise (sound) when environment is quiet. Not recommend to use next to bed.

max i would get is a 2 port.
also, if u have more than 1 port, 40 w, just not enough.
recently i picked 2 x45w single usb c on amazon , used like new for $4
work well

It saves space at my desk. Several items at my desk do not need to charge that fast. iwatch charger for example.
This is the one I have: https://www.amazon.com/gp/aw/d/B0C1CB2JR6
According to one of the reviews with a photo it "conforms to UL 62368".... But it doesn't say that an independent lab verified it. I would personally be skeptical
