And the good news...

My HTC Desire battery charger and in-car charger both fit the Nexus 4.
Excellent.

And I have found a manual.
Nexus 4 User Guide/Manual

Rather better than the user guide.
Right, off to play!

They all use Micro USB, right? Any micro USB should have fit no problem. My old samsung and htc chargers all fit properly, because they're all the same standard.

Yeah I've been using my HTC Desire charger until someone on here mentioned about different voltages, I checked and the Nexus has a higher output so I'm only using that now
