( auto ranging power supplies )

At-least from my collection. I'm pretty sure everything i have was sold in the US.

128k - 110v only

512k - 110v only

512ke - 110v only

PLUS - 110v only

Plus Plat - 110v only

128k Upgraded to a Plus - 110v only

Classic - 110v only

Classic II - 110v only

It seems everything else I have is auto ranging: 110 ~ 240v

1.5a Portable Charger

2a PB Charger

3a PB Charger

Mac II

Mac IIsi

Mac SE / FDHD - SE/30

MacIIcx/ci/q700+

All LC 1/2/3/475/q605

Even the Apple 40SC / AppleCD 300 is auto ranging

Maybe this info will help someone?
