Ego or pen style devices are great options for beginners as they typically features less settings and adjustments, as well as they’re usually a bit smaller. They are very portable, simple and feature usually only one button. For these devices, the actual battery cell is typically internal and requires only a simple charger cord when it’s time to recharge rather than external batteries.

Vape Pen Style kits are among the most simple to operate, easy to adjust wattage and quick to charge. Easy power settings allow for a stronger or weaker hit.
