Yeah, that part doesn't really add up. Maybe they meant to say that the same port on a laptop can be used to put power in or take power out, but that's not real

What's new is that you can now use a laptop charger to charge a phone.
- eloisant 7y agoWell, considering the shitshow that is voltage on USB-C, I would never try to charge my phone with my laptop charger. Maybe in a few years when USB-C is more mature, and manufacturer know how to place safeguards in devices so you can't fry it by plugging the wrong charger...
- SmellyGeekBoy 7y agoIs it? My understanding was that it supplied 5V (as per previous USB standards) until devices negotiated otherwise?
- elliottkember 7y agoIt does. I do this nightly. The iPhone has a fast-charge mode when used with a laptop charger, or their new fast charger, and it’s like 50%-in-30-minutes fast with either
- llampx 7y agoI've charged my (Huawei) phone just fine with Apple and Lenovo USB type C chargers. In fact I could even (slowly) charge my Thinkpad with my phone's charger. Would I do it with a no-name charger or cable or an older one? Hell no.
- tialaramex 7y agoIf you use a cheap non-compliant electrical thing it might go pop and all the magic smoke escapes. If you use a really cheap, really badly made thing it might catch fire or explode and hurt somebody. This was true for USB micro B chargers, I've had one go pop maybe a desk width from my head one day. It was true for laptop chargers, which have caused their share of fires. So USB C is not new on this. If you use high quality products it'll probably be fine.
