Sorry, but this must be a misunderstanding on Digitec's part, I never bought a barcode scanner...........

Gemäss dem Zubehör-Guide von Zebra ist dieses Presentation Cradle mit dem LI4278 kompatibel: https://www.digitec.ch/de/s1/product/zebra-presentation-base-rs232-barcode-scanner-zubehoer-10127453?supplier=406802 Zebra Zubehör: https://www.zebra.com/content/dam/zebra_new_ia/en-us/solutions-verticals/product/barcode-scanners/Handheld%20Scanners/LI4278/guide-accessory/li4278-guide-accessory-en-us.pdf Leider konnte den Artikel nur als Einzelstück in unserem Sortiment finden.

Unfortunately, this product does not have this function.

Yes, this is possible via Bluetooth. See the instructions for pairing with a tablet: http://images10.newegg.com/User-Manual/User_Manual_38-209-188.pdf

No, a USB cable is included. No power supply unit is needed as the unit is powered via USB.
