Used in battery mode on my TomTom One, on my iPod classic and on my Blackberry 9800. To my surprise, I note that battery discharge mode, on 3 devices ... I have the impression that they were loaded much faster than on sector. In, fact it's not an impression because I timed it and I accept that it works perfectly in this mode! Mode mains recharging devices via USB, no problems, consistent with a normal charge. As for the charger recharges the sector itself, it takes a normal time, a little over 3 hours to fully recharge. Apart from a bit heavy weight, I'm pleasantly surprised. The mains charger behind the un-clipped to facilitate transport and avoid congestion in a bag. Supplied with a short cable which allows precisely to use it as an external battery, comes with a USB cable provided with a nozzle and A (or simply put a tip for blackberry + a tip for tomtom one).
