AC load and it helps out well, it avoids lugging the base move or open the USB port cover. But it's still expensive for what it is. And then it really does not take much. You must not touch anything once it tient.Quand tablet is placed correctly in the base means a "click". There, there's really nothing. When placed correctly, the connectors are facing and the magnet (very low) maintains contact. But the slightest lateral movement moves the alignment of contactors. So do not expect to use your device while charging. Too bad it does not seem to be a better solution.
