What more could you tell about a charger or power supply much ... it does what it should and it is pleasantly compact design, so it is good certainly for the briefcase (purse for the ladies). I have several devices one after the other charged (mobile phone, Kindle, wireless headphones and tablet) - the charger is not hot here, so you can leave it calms also do overnight his service. The microUSB socket are known to have just about all current devices together so that this power supply is to use as a supplement, for example in the office well, the charger delivered with your mobile phone can have a secure place at home. At this price I can only say: thumbs up. The longevity has yet to prove ... if it fails, I will correct the rating accordingly the charger course.
