Hello,
I spoke to someone several months ago from ecigsales about using the Ultimo
and a battery pack.  I was told that I could get one on ebay for about $10.00.
 
I purchased one from radio shack for about $30 and it didn't work very well.
  I took it back.  Then I bought one from ebay.  It was called an APC. It
worked really well for about a week and then wouldn't work anymore.
 
I was wondering if anyone could tell me the name of one that you or your
clients use.  I'm not sure if they need to have a certain voltage or
something.  I have purchased a couple of the Ultimo's and really like them.
 
I have tried other items from elsewhere too... Like VP2.. Liked the longer battery life,
but it was big and clumsy.  I really like using the passthrough the best and
would really like to get a battery pack to use all the time.
 
Any input would be greatly appreciated.

I have a Kensington power pack and it's great for the first few puffs, but then the e-cig gets really hot and the throat hit is very harsh.  I used it with a penstyle.  It actually turned the cartridge filler brown, so I think it has too much power.  I'd like to know of one that has the right amount of voltage/mah.  I'm electronically challenged.

I use the Kensington K38021... haven't had the problems that Janet has had.  I love my Kensington! 

Try a Datexx. Pricey if you can't find on on sale, but a workhorse. A forum member sent me one, and the thing really works well. He got it for $10.00, but I have no idea how. This thing could power a spaceship...LOL

Should have mentioned, I've also used and liked the PC USA YP-M8565.

Here is a link to the power pack I use. 19.99 from Think Geek.  Works great and you can use with your mp3 player too. Takes 2 USB's  You can vape with your sweetie in the car   http://www.thinkgeek.com/gadgets/travelpower/b4b6/  or Vape and listen to music at same time.  Pack plugs into the wall and recharges.  A charge last me most of day (8 hours)
