Time to update this. These 500ma USB ports aren't cutting it anymore. Anyone know where I can get a unit to replace these with 2.1a USB ports? I looked to see if Magnadyne (the brand that made the original unit we used for this mod) made a new version with 2.1a ports, but it doesn't look like they did.

Hehe, thanks CTScott. Wouldn't know what to do with that in the first place. What is it? Do you solder it onto the PCB of the Magnadyne unit used in this mod. (the one pictured in the first post of this thread)?

It would replace the PCB of the existing one. You would simply wire the input of it to the lighter power feed and the output of it to up to 5 USB jacks.

Scott, would that not over-drive the ports? It's my understanding that the current regulation is done on the charger side, not the device, so using a 5A converter might be asking for trouble?

Generally the devices have the charging circuitry built within. Some devices have multiple charging modes, whereby a voltage divider circuit on the data pins tells the device if the charger is a high or low current capable charger. Each brand of device has its own system for this.

gotcha.... so most likely the devices would fall back to regular 500mA if they're plugged to such a "dumb" power source?

Some even lower (100 mA) than that with a dumb supply. Some of the older Android phones needed the charger to be intelligent and they would cook their own batteries if connected for long periods of time to even a low current dumb charger.
