I’m speaking from a US point of view. To my knowledge there are no 240 watt USB-C chargers in existence.
There are a handful that claim 240 watts but upon closer inspection only provide a max of ~100 watts per port.
There are cables sold with a 240 watt rating but no actual chargers.
Ruben isn’t super quick to put out updates but he makes up for it in quality. He was slower than some other devs to get Boost for Lemmy out the door but the first release was damn near perfect, stable, fast and only very minor bugs. Personally I prefer quality over constant updates.
These developers owe us nothing and it takes an incredible amount of time and lots of money to develop an app of this quality so no matter which app you choose consider paying and/or donating.
