I have 3 of these. The first 2 ports are "smart" ports that auto-detect what your device needs up to 2.4 amps. The next 2 are 1 amp charging ports which is pretty much the standard for every android perk phone out there. The last port on the front charges the slowest and will give charging errors on devices such as the LG Exceed 2.

This isn't really a problem for me because my other LG Fuels charge just fine in that port, but you may run into issues with that port if you have other more power hungry devices. The first 4 ports will charge anything. I just put a piece of tape on the cable of the last port so I know to plug it into a Fuel.

You could consider buying this charger for 9.99 if you want 5 smart ports that will charge any device: http://www.amazon.com/gp/product/B00MNZHHI8?psc=1&redirect=true&ref_=oh_aui_detailpage_o00_s00
