The product ships with 8 output tips to support a wide range of notebooks (except Macs). The external Li-Ion battery features 6600mAH (105Wh), which is a lot more than most notebook batteries.
AC Ryan claims their external battery pack will offer 1.5x to 3x the battery life of your current notebook battery. You can charge the battery with the MobiliT Universal Notebook Adaptor or with your own power adaptor because the product also ships with 7 input connector tips.
The product measures 220 x 130 x 15mm and weighs 600g. Perhaps a bit heavy but it's small enough to fit in your notebook bag.
The AC Ryan MobiliT Universal Notebook External Battery is already available in some European shops for 149EUR.
