Anyone know what's going on with the ground pin on apple chargers? Why add it if they don't include the 3-prong extension cord in any of their Macbooks (in the U.S. at least)?

- vanchor3 3y agoIt's not necessary to have the ground and there probably isn't enough cost savings to remove it. They've used the same design for years and just disconnecting the ground wouldn't make any sense because then the grounded cable would be pointless.
- astrange 3y agoIt's made that way so that if you travel you can replace the wall side with the local connector. Some of them are always grounded. Though, that's not really more convenient than carrying a power adapter around, so they didn't have to do it that way.
- RandallBrown 3y agoBecause you can get a cable that does have a ground and attach it to the charger by removing the "duck head".
- harkinian 3y agoHuh, my MacBook bought directly from Apple did come with a 3-prong cord, but I've seen plenty that didn't. I specifically remember having one, replacing it with a random 2-prong cord to fit into cramped outlets in high school, and my cautious friend saying "that's jank." Ungrounded connection sometimes causes tingling, a common enough problem that this Amazon 3-prong head even mentions it in the title: https://www.amazon.com/Grounded-Duckhead-Apple-Mac-Adapter/dp/B0B452LS67 https://www.amazon.com/Grounded-Duckhead-Apple-Mac-Adapter/d...
- Aloisius 3y agoThey use the same power adapter in other countries where ground is required. They also do sell a US 3-prong extension cord.
- astrange 3y agoSo you can use it as a bottle opener. (Try it, it works.)
