Do you need a 5V fixed voltage? Or you prefer varivolt for the same price?

Most of the time I set my vv's to right around 5v for my DIY juices.
Thats why I was interested if they were any good.

These boards work, but I would recommend a varivolt options. Approx the same price, but much more possibilities.

There is a 5V 3A boost module on eBay that I've tried - DC-DC Converter Boost Step Up Voltage Power Module 3V to 5V 3A | eBay

It worked OK, got ~4 hours from a TF 18350. See my 3-2-5 mod http://www.e-cigarette-forum.com/forum/battery-mods/241040-3-2-5-mod.html?highlight=3-2-5
