you will make it. and the reo mini is worth ittt.
definitely pick up a rebuildable for it, they rockkk on reos.
you will need to get an a7 mini, or, if you go with the reg sized a7, you need an unsealed 510to510
I love this thing with an a7 on top. Im about to buy 2 more a7 minis for mine, and more bats!
The 14500 batteries are the size of AA batteries, and they last a good amount of time for being so small.
But I definitely recommend you purchase a couple sets of them. At least 4 or 5 bats is good to have.
Having 2 chargers will also help you charge more bats at once.. which is truly a luxary.
The cheaper Efest batteries can be had for around 5 dollars, the popular AW bats are around 10 bucks.
I have 2 AW and one Efest and I'm probably going to get more efest bats for backup asap.
The cheap multichargers can be had for as little as 5.99 and they work great for my purposes.
If your into rebuildables or if your wanting an A7 mini for your Reo mini...
It would be good to practice spinning a coil that will sit at around 1.5 to 2.0 ohms.
Going lower than that would really depreciate the battery life of the 14500 bats.
(which isn't really a problem as long as you use a MG of juice that satisfies your TH craving)
Yes, you can spin a 1ohm or sub ohm coil and use it with the 14500bats, but the bat life will sputtle.
The thinner the wire, the higher the resistance. The thicker, the lower the ohm.
Your going to love the reo mini. Its 1 of my favorite devices EVER !!
