Not sure if it was mentioned in that thread but there is also the SWADJ-3, a bit pricey - 3A Adjustable step down switching voltage regulator
They may cost a bit more, but you also get more.
- You will be able get the full 3A (~2.9 at least) from it. Those China things
maybe ~2.3A.
- They are more efficient ~90 vs 80%, longer vapetimes.
- Specifically designed to be used with batteries.
- Nice warranty.
