Anyone know the difference between the Z1 and Z3 dock? I hear the Z1 fits the Z3 and is marginally cheaper.
Dock is universal design, but compatibility is achieved by model specific plastic inserts you have to place in the dock before you position the phone in the charger. So DK48 is the only one that has inserts for Z3 and Z3 Compact, and to be honest, the whole design is a bit screwed anyway.
My dock will not charge from USB port in my mac or monitor, it only worked for me from dedicated power socket USB charger, but such charger doesn't come in the box, DK48 only comes as dock, four sets of inserts and that's it. I guess they want you to use charger that came with the phone (which for me is stupid - after all you don't buy secondary charging dock just to use the original setup, but anyway).
I found the fit to be annoyingly fiddly, the magnetic point is very shallow, barely protruding from plastic insert and finding correct position is harder than it should be - the holes need to align perfectly and it's just a long slit, there is no bumper/end point so you can't just slide it to the end and it clicks into place - you need to find two one millimeter groves along roughly 12 cm side and make sure they clicked fully into holes. In other words the whole thing is just idiotically overengineered - using magnetic cable will be fifty times easier, and even those are fiddly (most magnets are weak and any movement or grip on the phone will usually make them pop out).
In addition to that, because fit is dictated by the plastic inserts, I doubt it will work with any case or bumper, unless it's some sort of super, super thin skin.
