This is your choice moving forward.
You either decide to buy a device, like a laptop, with a proprietary power input, or buy with an open-standard power input like USB-C, and then wait for the community to support that open-standard.
I decided >1 year ago to only buy USB-C devices and my resulting purchase decisions work fine with a range of charging options.
What takes time is for multi-port higher Wattage open standard devices because you have to wait til enough have bought to pull a response. So for example USB-PD is slowly becoming supported for higher Wattage.
If you had stuck with USB then even if the higher Wattage charges are not available, worst case, you can slow the device's drain via old fashioned 2A 5V USB, that works quite well. So I have a Pixel C, it's official charger is 5V 3A USB-C, but I connect, say, a Powercore 26800, it outputs 5V 3A from one port of its 3 and so I'm able to recharge quite well. The new Powercore Fusion 5000 is 3A output as is say the Powercore II.
Even if you can't get a high Wattage charger, a lower wattage charge slows the drain, so even a 2A output battery will go a long way to keep your device charged even if actively using so its flat slower than if you had it unplugged.
This is basically up to you, in what you decide to buy devices wise.
