Macbook 29w Charger with 2018 MBA?

[CrazedVW]

Anybody using the 29w MacBook charger with the new MacBook Air? I picked one up a few days ago to replace my MacBook and have two extra 29w chargers I bought to use with it. I saw on this article that there are some voltage differences but don't know enough about electricity/power to know if those differences will cause issues with the Air:

It will work fine, in theory and in practice. I've been trading off chargers with my rMB. No observable difference at all. There are some intermediate charging situations where the 30W adapter would be better, but there's no difference for these two computers.
