classmate charger power requirement

[Ed Law]

Thanks Alan. I have one last question.

According to the image Mark McLeod posted, the 2010 classmate charger output is 20V 2A. The 2011 classmate charger is 19V 2.1A. This Kensington Netbook Wall Charger is 19V 2.5A according to SilverD.

I am not an electrical person. We have the 2010 classmate. Is it okay to use this Kensington charger?

The Classmate Power adapters FIRST is providing at the Driver's Stations (or was intending to provide, they were not there at Peachtree, we were provided with outlets instead) are specified in the manual as the 19V version and compatible with both 2010 and 2011 KOP Classmates.

We've used both versions of the Classmate charger on our 2010 Classmate without any problem.

Rather than starting a new thread I thought it might be best to revive an old one. We seem to have lost our classmate power brick between last season and this season. We have one of the E09 classmates. Based off the pictures above the model number is an ADP-40MH AD. a quick google search finds this adapter. http://www.amazon.com/Replacement-Ad.../dp/B005NU6A9M

For those of you with working classmates do you think this is the right adapter and tip? supply voltages look correct but i wasn't sure about the tip size or polarity.

Thanks.

I haven't found a definitive answer for the size of the power connection. I do know that Kensington tip "H" works correctly. The AT&T Wireless link I posted last year is out of date, but I believe http://www.amazon.com/Kensington-K38.../dp/B001WAK6J2 is the same thing at nearly the same amazingly low price.

I just ordered the one off amazon that was recommend in the last post. Will let you know our results. It should be here sometime next week.
