This DK36 Dock for Xperia Z2 allows GSM recharge without opening the bar on the side where it would introduce every time the USB plug in normal times. In addition, the recharge of the smartphone can be done with the SONY Folio case without removing it. Very convenient. Only downside, the dock is really too small then you need to paste with double adhesive on the surface where it is desired to remove the smartphone charging.
