so small that can not be imagined. for 20 euros you usually get a 1000mah ego c battery. However, this one has only half the length (of course wider, but that does not a bit) has a pass-through function, so you can steam and recharge simultaneously, and it shows a the Volt and battery in percent and the seconds we have drawn. strong buy recommendation. for that price you would have to actually give more stars! have the Istick mini with a aspire mini Nautilus, is still extremely small. Who wants it even smaller fetches a gs16s it, then you have probably one of the smallest e-cigarette with variable-voltage adjustment
