I bought this charger to take on holiday with my Sony PRS 600 touch reader, and it was great. A choice of plug types (I took them all, as I wasn't sure which ones I'd need)and each plug type fits into the main plug. Very easy to charge. And I did have to charge it a couple of times. The only reason I'm giving it 4 stars, was due to a little stiffness getting the different plug types in and out of the main plug - but then to be fair, it would be no good (or very safe) if they just fell out. But just wondering if they could make it slightly easier to do? Otherwise, if you do travel a lot, and don't want to take your laptop with - it is a very useful charger to take with.
