I agree - I wonder why Chinese junk that basically barely works and not for long even then has managed to establish such a strong foothold on the retail market (particularly Amazon). I had the same experience - moreover my charger had multiple ports, but as soon as you plugged more than one thing into it, the wattage would drop drastically. my 100W charger would do 30W on port 1 and 10W on port 2. And that was the optimal case - more often than not, using more than one port would make devices randomly disconnect.

Be happy the wattage dropped. When I connected 2 fast charging devices my charger just fried.

I just had a 4-port USB brick burst into flame. It certainly would have burned down the house if I had not happened to be in the room. It had sat untouched for an hour before the event.

  Wow, what brand?

    These brands are like the ship of Theseus - you'll never get the same thing twice.

      Better than the brand is the picture of the device (before fire, hopefully) as all the yumcha brands off of Alibaba will usually keep the exact same physical characteristics.

It's cheap and there's little responsibility for selling crap. Amazon is the only site I'm aware of where you can actually somewhat judge the quality of a product through reviews, and those too are often dodgy as hell. Otherwise it's all just the same fake pictures and outright lies about specs. And nobody cares because it's cheap. Companies selling under brands want a premium for them (Anker, Aukey) and "no name brands" you can actually put a little confidence into (Ugreen, Blitzwolf) are, for some reason, rare.

That isn't so surprising nor uncommon even among high-end chargers. Many multiple-port chargers can only generate one voltage other than 5V. So, you charge your laptop at 100W means 20V*5A, then connect a phone that can only negotiate to 9V. Now your laptop can, at best, only get 45W. But laptop and phone might also have to share the same 5A, meaning something close to what you described. (or, your laptop might not support 9V ... in which case I'd guess one of the devices would disconnect?) You might be better off using a USB-A port if the charger has one, then your laptop could perhaps remain at ~100W and your phone might still get ~10W. (Assuming charger and phone doesn't also have quickcharge which might complicate it further). Or, perhaps charge your phone via your laptop (yes, negates the point of a multiple-port charger, but if you are in hurry - otherwise, slow charging is preferably anyway) A good review will test this, and a good product page will specify this (but if your are not looking/thinking about it it is easy to miss).
