Magsafe2 to USB-C power plug adapter?

If one didn't ship with your 16-inch MacBook Pro, order Apple USB-C

(or spare?) adapter from Apple online, or Apple USB-C from OWC.

OWC, at discount, slightly under retail. Usually these do not include

the charge cable, from Adapter to Mac. Nor is there an 'extension

AC cable' (a three-prong grounded cable; normally is an option).

[There are quality USB-C Adapters and Cables from Belkin

&/or sometimes an 'Apple' one included w/ retail MB/Pro kit.

A multiport Dock or powered Hub may be good solution too.]

No conversion AC adapter exists, to an connect older MagSafe

1 or 2, to power newer MacBook Pro equipped with USB-C ports.

The matched adapter and cable shown below should be in the

original kit with new MacBook Pro 16-inch; or maybe in retail.

Unless you happen to find the correct voltage and amperage output

with proper fitted plug/port shapes; that in itself is near impossible..

..anything 'cheap' would likely also be a compromise & void warranty.

A 'late edit' above, includes link to an Apple cable to match the 96W

Apple/MX0J2AMA/ USB-C, for use between adapter & MB/Pro 16-inch.

And should you not already considered time factor with AppleCare+

there's limited duration (60 days?) from macbook purchase, to get

the extended warranty. I'd bought AppleCare on all my new macs.

{..old Apple power adapters in good shape are collectable, are

keepers and worthy of re-homing to other vintage mac users..}
