EFEST SLIM K2 – 2 Bay Travel Charger


EFEST SLIM K2 Travel Charger

EFEST has definitely filled a niche for us traveling vapers!  The Efest Slim K2 Charger is a 2-bay charger that supports charging at up to 1AMP per battery (when paired with a 2+ Amp wall charger).  The EFEST K2 features reverse polarity protection, over-charging detection, and short circuit protection. Each charging bay has a LED light indicator on top to display the status of your charge.  This K2 Slim Charger is designed for ultimate portability, especially with road warriors in mind.  Why carry around a bulky A/C powered charger when you already have 1-2.4 amp adapters you’re taking with you for your phone and/or tablet.    It’ll even charge your batteries using your laptop USB port.
