I stumbled across this A/C adapter and it looks like it will work with the i-Opener.
Delta Elec. Model: ADP-60JB (OEM for Acer No. ADT-K61 Part No. 91.47A28.003)
Input: 100-240V AC~ 1.5A 50-60Hz ( Automatic Line Select )
Output: 19V DC 3.16A
Connector approx 2.1mm Inside Diameter, 5.0mm Outside Diameter, 11mm Length
Power Brick Adapter Only ( Standard Adapter Cord Needed )
IMHO, $20.00 for a 60W laptop power supply is a great deal.
I think that the connector will work as-is. This looks like it will be a nice cheap replacement supply for those that need more power for their i-Openers or have fried their stock supplies (because they needed more power <g>).
I have a few of these on order that should arrive next week. I'll test these with an i-Opener when they arrive, unless one of you west-coasters gets to it first (you have an advantage on shipping time from CompGeeks).
Electronics run on smoke, if you let the smoke out they won't work
