It works well with my phone, as the plug-in charger receiver on my phone is not reliable. This only comes with a USB adapter cord, not a wall plug. It's rated at 1.5 - 2.0A input current. I have a USB wall plug from another charger that only puts out 0.5A, and will cause it to charge really slowly. As it is, I plugged it into my laptop and that seems to work great. As it is, it's a nice mahogany wood and finished well. The back insert is made of the same material, but sticks out about 1mm. The USB cable plug in does not seat completely against the wood, leaving about 4mm of the plug exposed. This seems odd, but unless you have three year old boys who play with everything that they can reach, it shouldn't be a problem. Looks nice and obviously made from quality materials. Just wish they'd included a wall plug for this thing.
