Was with him in the autonomy of 3 weeks. It was enough for this time to charge the smartphone (every other day) and Glo (every day). I've already charged several times. A day is charged with a two-ampere charger. Haven't tried more power. Many write here that its size is a minus, but I want to say that a battery of such a volume and a smaller size is simply not found now and the size is quite adequate. Here you can choose - a large amount of energy or a small size of the device.
