Sony Xperia Z charging dock (DIY)

There was a time when buying a mobile device such as the Palm Pilot meant having a dock included in the package. Nowadays we’d seldom see smartphones packaged with docks until Sony started creating Android based Xperia phones.

I’ve owned a number of Xperia phones, the latest being the Xperia Z. One of the things I love with my Xperia Z is the fact that it’s water resistant. I don’t have to worry about getting it wet — I think all mobile phones these days should be at least water resistant. When I got my Xperia Z, the dock wasn’t available yet, at least locally.

At first, I thought that I could live without a dock after all, I’ve own quite a number of iPhones and Android phones and didn’t use a dock. As it turns out, it’s a bit of a hassle having to open the flap covering the USB port on the Xperia Z whenever I had to charge the phone. These days, the newer Xperia Z1 and Xperia Z2 seems to be packaged with a dock already which is a great thing!

Now that I’ll probably be looking into replacing my aging Xperia Z with a much newer phone, at this point, I thought it would be nice to just create my own dock for the Xperia Z — I thought it would be a great way to start doing some hardware/software hacking as a hobby.

Basic Information

I started doing some research on what would I need to be able to use the available charging pins on my Xperia Z. As it turns out, the XDA Developer’s forum has a whole thread dedicated to it ( Upon reading some of the posts, I found out that it’s actually simple enough to create my own Xperia Z dock. All I need would be some materials:

Bill of Materials

The first thing I’ve decided for this project was that I wanted my Xperia Z dock in the portrait/vertical position instead of the landscape/horizontal position of the official Xperia Z dock. In case you’d want to, just buy the Xperia Z dock (DK26) at Amazon.

If you’re feeling adventurous or wan’t to spend less than the cost of the official Xperia Z dock, read on.

After giving it some thought and looking in my treasure chest of parts and accessories, I actually have everything that I needed to create my own Xperia Z dock.

  • Mobile phone stand. I am currently using one of those cheap plastic stand I bought locally. Below is an image of the stand. The great thing about this particular stand is that it has a compartment where you can hide your long USB charging cables. Cost – $3

  • Charger with pogo pins. For connecting to the Xperia Z’s charging plates. I decided to use a universal car charger for lithium battery packs of cameras. Cost – $2

Enhancement Ideas

Now that I’ve got my own Xperia Z dock, I’m already thinking of ideas on how to enhance it. Any suggestions?

Hello Sir,

Good day! I would like to ask, how did you distinguish the positive and negative polarity of pogo pins? Thanks! 🙂

Gerry Ilagan

The one nearer the USB port is the positive terminal.
