The device comes in a small well-designed box. The part itself is about processed Zigarettenschachtel- large and very valuable. The delivery is still a manual in German and a USB cable. What could we do with it? * Power Bank The device has a rechargeable battery with 6000 mAh capacity and may, provided that it is fully charged, can be used as a power bank. A normal mobile phone can thus be loaded approximately 2x. * Router There is a LAN cable input, if you (as on home router or in the hotel's LAN access) invests there an Internet connection, the unit is building a wireless on. That works wirelessly. If for example in a hotel Wireless exists with the password, the device can use this WLAN to connect to the Internet and builds for the remaining family members own Wi-Fi. So can all using their phones in the hotel with only one (hotel) surf access. The router settings you can make using a free app, or in which one enters through a web interface in the browser 10.10.10.254. The access data can be read with a sticker on the device. * Streaming Service a blast! it includes a USB stick or a micro SD card, or even a hard disk on which music files are stored. The device then displays the data via the WLAN via DLNA available. You then need a WLAN-enabled device which can play the files. This works also with mobile phones or tablets with appropriate apps. * File Service Finally, you can file between the Micro SD card and the USB connector slide back and forth / copy, or to / from mobile phones or tablets (all with the help of an app) to send or receive. This works really great. And the great thing is you can in the car, make in the woods or in the subway. :-) I find this really great all-rounder! He will be constantly on the move to be my companion.
