Hello to u all I'm a 29 year old male from the uk I smoke around 20-25 cigs per day brand of choice is lambert I am about to order my first e cig which is the njoy npro duo just wondering if anyone out there has any info like how long a fully charged battery lasts and what strength refill do u recommend I get and also is this ecig any good for a first timer like me
Well that wasn't fair. Was so worried you'd waste money and end up with a product that would only frustrate you later that I totally missed the nic strength part.
It really doesn't matter which brand or how many you smoked. Everyone eventually finds the nic level that suits them best. If the mgs of nicotine are too high you'll know because you'll get a little nauseous. An oops-I-had-one-too-many-cigarettes type feel. If they're too low (for me anyway) you might start craving analogs. You might try starting with something in the 12mg, 18mg or 24 mg range. Here are a few ways you could go about that...
You could just buy 3 flavors in the 12, 18 and 24 mg range and test those strengths, or...
You could also try just a 24mg flavored bottle, a couple of empty 5 or 6 ml dropper bottles to mix in, and then add some PG or VG to thin the nic level down. The flavor might also be diluted though unless you have 24mg with extra flavor added (sometimes called "doublers"). As an example: One part 24 mg nic + 1 equal part PG will give you a 12 mg strenth nic liquid. Two thirds of a bottle of 24mg nic liquid + one third PG will give you 18mg nic liquid, or...
You could buy a 24mg flavor of something that sounds like it will taste good mixed with another flavor that's 12mg. Let's say a 24mg tobacco flavor and 12 mg carmel, or 24 mg cheescake and 12 mg blueberry (you get the idea) ...then mix them roughly half and half in a spare bottle to get 18 mg. You'd only need to buy 2 flavors instead of three this way.
These are just a few suggestions. There are many ways to do this, and I'm sure others will chime in.
Good luck on your journey and happy vaping!
