The new and improved Promaster Universal+ Lithium Ion Battery Charger is smaller and more portable than the original design. Despite its change in size, the Universal Charger still accommodates a wide variety of batteries and does a better job of fitting many of today's smaller sized batteries. A "little plate" can be inserted in the base of the charger to raise the height of the charging platform to allow easier alignment for the smaller terminals. Newly designed terminals, now using a spring loaded mechanism, make better contact than previous versions.
The new design also adds a USB micro B port that allows you to plug a phone/tablet style battery pack charger in and recharge camera/AA/AAA batteries on the go.
