To date I have purchased two chargers which are excellent for charging my phones. I just ordered another charger today for my wife. I am very well satisfied with my purchases.
My wife bought me the USA one as an early Christmas present due to my job. She got it due to me being on my phone alot for work. Having wires connected to a power bank was annoying. I love the concept, but I plug it in and literally watch the charger go from full to dead in roughly 30 minutes without even getting a full charge. She bought me the samsung version.
Ordered for iphone. Got android charger
