[Nexus 10 Accessories] Royal2000H:
Background: (feel free to skip this)

In my search to get a good car charger for my Nexus 10 (that would also be good on my Galaxy Nexus), I checked out a bunch of sites and manufacturers and reviews for the perfect charger. I also wanted it to be dual port for two phones at the same time in case my girlfriend is in the car.

So many 2A chargers are not actually 2A, they may be 1A to each port max or they may only work as 2A on an iPad. Android devices look for shorted out data connections in order to pull more than USB power (500ma). So a charger has to both offer 2A or more and have the data pins shorted in order for us to get maximum current to our Nexus 10's. The Apple/iPad chargers work differently. They either have smart chips or specific resistances between the data pins in order to specify current draw.

What you came here for:

After the long search, the BEST while still very affordable car adapter, is the *drumroll*:

Bracketron Universal Dual USB Car Adapter

2 ports like I wanted. 2A like I wanted.

Contrary to the "Universal" listing, the adapter was likely made for the iPad. So charging out of the box is USB (500ma). But it's easily fixed in under 3 minutes!

Instructions:

1. Pop off the round silver plate on the front (with your finger/nail).

2. Unscrew the silver part in the back. Don't lose the spring hidden inside.

3. Slowly pry open the black plastic. It's fairly rigid and you'll hear some clicks. If you don't open it like a crazy monkey, you won't damage or break any plastic.

4. You'll see by each USB port 4 wires going to the port from the circuit board. The 2 middle pins are the data lines, the 2 outer ones are the power lines.

5***. You want to short the data (two middle) pins. All that means is you want them touching electrically. Takes about 10 seconds to do with a solder iron (once it's hot ;)). Just flow some solder between the two pins, no wire needed. Do the same for the other USB port on the other side.

6. Put the plastic and screwed pieces back together. Plug it in and you should see AC charging! :victory:

***If you're poor at soldering, don't worry - you're doing this on pins in the air, not directly on the board, so it's an extremely easy soldering job. If you've never soldered in your life, you can possibly use some wire instead of solder to connect the two and find a way for it to hold in place. But seriously it's an easy solder job and you should probably learn how to solder anyway.

Reading the instructions I wrote takes longer than making the modification. :cool:

Why this adapter if you have to solder? It's the only one I can find with dual ports that can actually give 2A to an ANDROID device. Why this of all the other adapters you can attempt to solder? It comes apart extremely easily so you don't break any plastic like many of the other ones. And the adapter is really small so you don't have a huge piece of plastic hanging out of your power port.

Fair note: it looks like it may give 2A max, so charging both my 1A phone and my 2A tablet will actually be slower. But it's perfect for charging the tablet at full speed when by itself or two phones at full speed.

Also, credit to Amazon reviewer 'K. Crawford' for suggesting this adapter as a good one to mod.
