The HUAF in particular is one i like - it has a quality feel, amazing battery life and can power 2x 2.5 amp devices and a 1x 1amp device at the same time should you wish.
Its a bit bigger and heavier than it may look - about the size of an iphone 6 plus and slightly heavier.
Its also good for charging my iphone and bluetooth earphones so gets plenty of use.

Thanks Mel, that's an interesting alternative. Would I be right in saying that as its a battery in complete isolation there can be no distortion noise, or does the fact its a sensing charger mean there is something else electrical going on.
