Yay for google. Found a very helpful illustrated guide on another forum. Best I can tell it's a DSE103 which is the same as Blu.
If it's a 401, I can fully understand your frustrations with it, it was my first PV also. Haven't used it in a long while, as better equipment has provided better vapor, flavor, reliability. I went the ego / 510 / riva route, and graduated to a
mod to provide the 3.7v that your 808 can in a smaller package.
When you find YOUR perfect PV / flavor /
vape, you'll know, we can give advice by at this point of the technology, everyone's taste is different.
Battery-wise, I've found the more mah the better (lasts longer per charge) and the less proprietary (available anywhere) the better. YMMV
p.s. googling your criteria "808, supplier, battery"
and ECF, will give you ant ECF
threads with information. The ECF internal search function can leave something to be desired.
