Great. So we got EU laws to mandate USB-C chargers and then get manufacturers that flaunt the spirit of the law by rejecting lower wattages.

My laptop refuses to charge for 45W chargers as well, but I can almost understand it.

When plugged into 100W chargers while powered on, it takes ten minutes to gain a single percentage point. Idle in power save may let me charge the thing in a few hours. If I start playing video, the battery slowly drains.

If your laptop is part space heater, like most laptops with Nvidia GPUs in them seem to be, using a low power adapter like that is pretty useless.

Also, 100W chargers are what, 25 euros these days? An OEM charger costs about 120 so the USB-C plan still works out.

Other manufacturers do similar things. Apple accepts lower wattage chargers (because that's what they sell themselves) but they ignore two power negotiation standards and only supports the very latest, which isn't in many affordable chargers, limiting the fast charge capacity for third parties.

Which laptop is that? My Razer with 5070 will take 45W chargers just fine, so do the ThinkPads, my work 16" MacBook and previous Asus Zephyrus with 4070.

		I was on a trip a few years ago and had only brought my “compact” 45w usb-c charger since the brick that came with my work ThinkPad (one of the high end 16” screen models, maybe p16?) was enormous. When I plugged it in Windows complained that the charger was insufficient to charge the laptop. I think it at least kept it from draining the battery though. I had to run to Walmart and get a 65w charger which did the job fine.
