So I was tired of having to hold my phone while plugging in a microusb cable after I’ve docked it in my car. I couldn’t find very many car docks out there with wireless charging, and I read that Nokia’s wireless charging car dock didn’t work very well on the Nexus 5.
Previously I made my own Qi car dock by taking apart an LG Qi charger. But now that I have Google’s new charger I made a new one that’s much better. The magnets in Google’s charger are stronger and it looks a lot cleaner. I didn’t need any glue, tape, or additional magnets either. To make your own all you need is:
The magnets in the nGroove Snap are just strong enough to attract the magnets in the wireless charger. The silicon material on the foot of the charger is also very good at sticking to certain surfaces like the nGroove Snap. Because of that I was able to drive around for three hours with my phone on the charger without any problems.
All you need to do is mount the nGroove Snap and then place the charger on it, and that’s it! I routed the cable behind my dash to make it look a bit cleaner (instructions here).
So I built my own. I originally posted everything on the XDA forums. Since the Nexus 5 has four metal discs inside it, it self-aligns when placed on the dock and stays put in that position. You can see it self-align in the gif below. I drove 45mins from San Francisco to San Jose and it never fell off. I was using GPS (Google Maps) and it looks like the magnets don’t add too much distance between the phone and the transmitting coil, my battery meter went up a little bit. More pictures here.
I used the following items:
For the final iteration, I reassembled the charging pad and everything holds together with just the magnetic force. This is what I did:
Ok and that’s it. The part about the three magnets and the plastic washers was done after I took these pictures. I initially didn’t do that and found after a few hours that the nGroove metal plate’s adhesive has come off the soft material top and the coil/ferrite/board fell off.
While this works great with my black Nexus 5, the white Nexus 5’s back is less grippy, so you might have to plastidip the magnets or add some kind of grippy material between them and the phone. I also tried this on the 2013 Nexus 7 but that requires more magnets since it is heavier. Also on my Nexus 4, since it has less metal inside, has a smooth glass back, and is heavier than the Nexus 5, it doesn’t work very well on this dock. You’ll probably need to get a grippy case for it and add more magnets.
Here are some pictures of the final version, sans washers.
And here are some pictures after I routed the wire inside the center console. After you take out the shifter boot, little cubby, head unit, and air vents there is a ton of room inside to route the wire. The front plate of the AC vents snaps on so I was able to pry it open just enough to squeeze the thin wire in. I cut out a small notch of plastic to give the wire some room without blocking any of the vents’ moving parts. The only downside is I can’t close the little cubby anymore. Oh well.
