The Q, by Pod King, is the latest iteration from a brand with years of credibility in the vaping industry.  The Pod King Q has a robust 10ml e-liquid tank (5% Nicotine) coupled with a rechargeable 1000mah battery.  Therefore unlike other disposables, if the battery dies prior to the liquid all being gone you can simply recharge it.  Furthermore, it eliminates the weak puffs experience by other vapes at the end of battery life.   An adjustable airflow on the base of the unit allows you to fine tune your vape to your preference.  Each Q disposable is capable of approximately 3500 puffs, and they come in a great array of flavors.  Here is the difinitive Pod King Q Rechargable Flavor List:
Aloe Grape
