You should look into getting a Smok SCAR P3. It's a compact vape with a built-in battery that has great battery life. It comes with 2 types of tanks. One for standard vape juice and one specifically for salt nicotine based vape juice (RPM for salt nic and RPM2 for regular vape juice, each of those tanks has a different coil and you get a starter coil in your kit for each of those tanks in the SCAR P3 kit). Salt nicotine is going to be the way you're going to want to lean towards. Standard vape juice comes in concentrations of, all in milligrams, 0-3-6-12. Salt nic comes is 24 and 48. So I believe salt nicotine might be what you're looking for. Another benefit I've found is that the salt nicotine coils run at lower wattages so it doesn't exhaust the battery as quickly. The tanks are held on to their battery base With magnets so it's extremely easy to remove and the coil literally just pulls right out and the new one slides right in. Best of luck.
I'm currently using the valyrian 2 pro tank on a smok arcfox and I absolutely love it! Best flavor I've ever got out of a tank! Vape boss is definitely the best shop to go to they will get you taken care of for sure!
