Great little charger, could be a slightly cheaper.,
Verified Purchase(What is this?)
This charger does it all - phones, tablets and Kindles.
Works great, looks fine, small size, doesn't get hot when charging (just warm). Would be brilliant if it was slightly cheaper but for the price it's still a very good charger.
5 Volt output at a maximum of 2.1 Amps.
UPDATE: The charger makes a horrible whinging/whining noise when plugged into a socket without being plugged into any device. As soon as you connect a device the noise stops. Might be a sign of bad build quality?

It is a little pricey I will agree but most of the cheaper ones have a much weaker output.
As for the whining sound, this is pretty common sadly. It is annoying but almost all USB chargers do it. Asus, Samsung, Apple, HTC, Motorola, LG in addition to cheap ones. For some charging units (even of the same type) this is more noticeable than others but it usually has no link with performance or build quality and so it should still work just fine and is nothing to worry about in that sense. Generally it is the higher output chargers (the better ones) for which this is most noticeable. For example if you buy a 700ma charger (or less) it will almost always be silent. Generally you get this noise to some extent with 1.2a+ chargers but particularly with those which output 1.8a or more.

I think this is symptom of it being a switched-mode power supply. I have a Samsung charger which makes the same noise when plugged into a Blackberry: the Blackberry cannot charge at 2.1 amps so the power supply has to decrease the switching frequency in order to provide a lower current: when the frequency reduces it can come into the audible range of the human ear.
