I now also use the Zen Charger "ZESC02W / 00" and invite my Nexus 7 (2013) so on. The shop goes quickly from equip and without the hassle of plugging in the USB cable. The charger will turn off after you hang up my Nexus (in the sleeve), and starts the charging process. The loading time is a bit longer as with USB cable and the corresponding charger. Unfortunately, the charger in full Nexus battery switches - not down - as described. My request to the customer service of Zens was as follows:.. With a Nokia Lumia for example - turns off the charger. The NEXUS is built and programmed the this Zens - Charger - not - off - it stops the Nexus - internal - with full battery charging. So there are no damages to the NEXUS. , Since this charger without problems and quickly his task - LADEN - done, cause any damage - there is of me - 5 points.
