This information might be out there already, but after noticing the LG charger works much faster at charging my G2 than a Nexus 7 charger, I did a quick test using CurrentWidget to record the charging currents for each setup to see if it's the special LG USB cable or the LG charger base / AC travel adaptor (or a combination of both) which is needed to enable the fast charging.

It's been mentioned here before that there are extra non-standard pins / contactors on the LG USB cable which presumably are used to deliver higher charging current, but it seems that there is nothing special about the LG charger base / AC travel adaptor which use these. Using a standard generic AC charger with a USB port on it is enough to charge the phone quickly as long as the LG cable is used. (and provided its rated for a current output >1.8A)

LG charger + LG cable ......... 1600mA
LG charger + standard cable .... 250mA
2A charger + standard cable .... 270mA
2A charger + LG cable ......... 1600mA


(Tested using D802 running Mahdi Rom 07/29)

Neither. I use a multi-USB charge station and a third party USB cable and get high speed charging on my G2.

A number of cables will work but it seems hit and miss. My Nexus 10 is just the same, but even worse. With the 'wrong' cable it can take 3 days to charge, even when off.

I use a Blackberry Playbook charger rated at 1.8A/5VDC, and according to GSAM it charges at up to 1500ma depending on battery level, about the same as the stock charger and seems to charge it just as fast... pretty cheap too, just over $5 shipped... http://www.amazon.com/gp/product/B00...?ie=UTF8&psc=1
