still mad that apple won't let me plug in four chargers at once
@jleedev my only apple device is an Apple IIe but I can only hope they've improved the battery life on their devices since then
@phooky my "use case" is the 96W brick is expensive but i have cell phone chargers falling out of my butt and this thing has 4 usb-c ports
@jleedev what it you plug one of the ports into another port? will it charge itself?

@jleedev @phooky
Not really the OS fault tbh. As long as the charging circuit at that port detects incoming current, it will signal as "charging", regardless that the battery delta is in the negative.
It really has no way of knowing that the current it receives is basically the same as the current the laptop sends off from another port. So the laptop can't figure out that you're feeding it it's own electricity and doesn't think to interrupt this whole wasteful enterprise.
Don't know if there's anything that can be done on the circuitry level, where a laptop can detect this. At best you can tweak the OS, to where only positive current deltas at the battery is displayed as "charging", but it would cause other UI problems (like the user thinking the charger is broken, when in fact his laptop uses more power than the power brick can provide).
@Xalef @jleedev @phooky
Plugging a laptop in itself definitely adds a power loss. The amount will depend on how well made the circuitry is. In absolute worst case scenario, it could halve your battery life, as charging from battery banks results in about 50% efficiency. An external battery of 10000mah can at most charge a 5000mah phone for instance.
