External charger frees up your ThinkPad notebook so you can continue to work off the system battery while charging a spare battery. Increases your unplugged mobile computing time and helps ensure you have a charged battery when you need it. Note: requires the use of the ThinkPad 90-watt AC Adapter that comes with a ThinkPad Z Series notebook (AC adapter also sold separately).
Wow (not the good kind either)
Our organization ordered a quantity of these, and when we got them I thought it was a joke. This is an incredibly poor design. We were essentially looking for something the battery would drop down into...not something that the battery settles in. And the charging head on this thing is ridiculous. Your have to pry open the spring-loaded clamp, and you're not even sure if it is secure. Half the time it pops off the battery...absolutely mind-boggling that this made it into production.

Worst design ever
This has to be the worst design I have ever seen for an external battery charger
