What type of moderation is this.

This portronics charger is marketed as 100w charger with dynamic power allocation. I ordered one from their site. Now the charger felt very off so I ordered a usb c tester and no wonder this this is cheap.

1. when you use single port c1/c2: this gives 100w to laptop no problem, it overheats but atleast does the job. It can do 5A, so samsung super fast charge 2.0 is possible.

Similarly usb a gives 20w and supports turbo charge upto 20w in mi devices.

2. the problem starts when you start using 2 devices simultaneously.

C1+C2: the charger detects the higher power device and routs 55w max that one and only 15w max to slower device. So 70w max. So you can only fast charge 1 device. No superfast charging in 2 samsung. Also 5A is disabled if 2 devices connected. So if you have 2 samsung, 1 will charge at 25w and another at 15w. These figures are very much different from advertised power allocation. Don't even think about 3 or 4 devices. The charger will give up on proper power allocation and becomes a furnace.

3. c1+c3: c1 will give 55w and c3 15w. But if you use usb a +c1, usb a gives 20w and c1 is at 55w.

So unless you need full 100w output for laptop, its better to just buy 2 65w or 45w charger than this. Or look for some better brand.
