Definitely agreed on good chargers, but, regrettably, standards keep changing, so here’s my anecdotal experience/advice. I’ve had multiple issues - my pixel 3a charges faster than my Pixel 7 (comparable battery life) and my 7 doesn’t rapid charge on my ~2020 bricks. I have great cables, too (finally) and after swapping bricks/phones/cables, the problem stays with the brick/7 combos. Same for my SO’s S21 Ultra or whatever. So, after years of practice of reading wattage specs, I’m now stuck reading the bullshit product descriptions saying iphone 17/s24 compatible or whatever is contemporary to my devices. I charge slowly nightly, so the ability for proper fast charge is important for the random needs otherwise.

If you’re using a type-c device, you need a C brick and C-C cable. But, what I’ve recently discovered with my latest pair of excellent bricks, is that “dumb” type-C devices may lack the negotiation ability to get C-C power. I must use A-C in that case to charge my flashlights. Probably why they all come with shitty A-C cables. I already carry A-micro for my older devices anyway
