Cold, thick juice can be avoided if one makes their own E-Liquid.

If you don't make your own juice, I guess Squonking may be the best option.

I've never owned such a device, however I understand they are great for huge clouds and excessive juice consumption.

If you live in cold climates, use more P.G in the juice to combat the problem?

After one or two hit's, the juice has warmed up from the base and will work fine anyway.
Just pull a few hits with no power before you press the power button = no dry hits.
When the base gets hot, it heats up the juice, then = no problem.

Just a suggestion as I'm no expert on squanking
