What is the Thunderbolt 2 output power of the a1398? I want to buy a hard disk box and replace it with a 5v 1a emlc ssd

Thunderbolt 1/2 is 18V 550mA 9.9W according to https://en.wikipedia.org/wiki/Thunderbolt_(interface).

Thunderbolt 3 is 5V 3A 15W according to that wiki page and https://en.wikipedia.org/wiki/USB-C

That LaCie Thunderbolt USB 3.0 enclosure also supports USB 3.0 which is limited to 5V 0.9A 4.5W which is probably not enough for the enclosure and the SSD.


That SSD is 5V 0.9A 4.5W - seems like a lot but I don't know if it's too much.

This page suggests 4W total (SSD + enclosure) as typical:

There's more info at:
https://www.lacie.com/ca/en/support/mobile-storage/rugged-thunderbolt/
but I don't see anything about the max current/power of the SSD.

I think normal SSDs are under 3W.

Some go up to 4W:
