The Jacvapour Series S vape pen is high up there in our favourite list at ecigclick. It manages to keep a compact form while still offering plenty of battery life with it’s 900mAh battery. The Series S17 is a plug and play type device. No variable wattage setting to be getting your knickers in a twist with. The battery recognises different resistances from your coil and sets the best output wattage accordingly. The kit comes complete with a tank that offers very good flavour. All you need to do is add e juice. Tip: We would recommend buying a second battery with the kit to act as a back up and use in rotation so you are never ‘vape-less’ due to charging or the battery running out suddenly.
