Daniel, we (wife and myself) own a 2a and my 3a pro, I previously purchased ugreen adapters/chargers for my daughters iphones which worked really well. Unfortunately, these did not perform in the same way for our Nothing devices. So I purchased from Amazon twin micro c charger/adapter called “Speedy” its a 45w charger (charges two devices simultaneously) My daily cable which is left plugged in wall all the time (switched on at the wall, not sure if that’s good long term?) is my old 18w pixel cable 18w maximum that was, but it performs really well, I mean delivers a fast charge, every time. That said, I also use various cheap micro c to micro c cables, and they too perform well. So, I purchased a couple of these Speedy adapters, as the pins collapse ideal for travelling. Hope that assists.
