Barrel plugs ARE better because there is very little certainty about them so you always have to check the voltages/polarity. Because usb-a is near ubiquitously

Barrel plugs ARE better because there is very little certainty about them so you always have to check the voltages/polarity. Because usb-a is near ubiquitously 5v over certain pins most people will plug in a usb-a into any socket they see.
- eternityforest 3y agoIt's the designated dumpster fire "Lol you're on your own" plug! Probably the best connector we've got for things that need it, but I'm glad we have USB-PD power now
- sleepybrett 3y agoThat's kind of my point. There is no standard at all with barrel connectors, usually bigger connectors means more watts but not even that is true as a rule of thumb. When you see a barrel connector all the following things are true: 1) no voltage can be inferred 2) no amperage can be inferred 3) Not even the polarity can be inferred You must check the device and the wart for all that information.
