Recommendations for a good e-cig.
If you need something that looks like a cigarette, consider a Volt (KR808D-1) by Smokeless Image. You can get them with either a manual battery or an automatic battery. The manual battery has a slightly easier draw; you might find the automatic battery a little more convenient. Consider getting a system with one of each type. There are 3 sizes of
batteries, the longest one lasts longer. You generally find you're charging your
batteries several times a day with this system.
A system with a bigger battery will save you from having to recharge it as often. Consider a Riva 510, Ego, or E-Power from Liberty-Flights. The E-Power is the biggest model, but if you go with the model with the 18650 battery, you'll get ridiculous battery life. Another feature of the bigger battery models is that you can try low-resistance atomizers or cartomizers with them and they will give you more vapour and flavour.
Another big battery model to consider is the Echo. It gives a warmer vape than the other systems and holds a lot more e-
juice. The battery is compatible with the Volt (KR808D-1) cartomizers.
The batteries are rated in mAh. Typically a 650 mAh battery may require charging once or twice a day depending on how much you vape. Or longer if you're a casual smoker.
There's more, but I imagine you'll already have questions.
