EFEST SLIM K1 Travel Charger

EFEST has definitely filled a niche for us traveling vapers!  The Efest Slim K2 Charger is a single bay charger that supports charging at up to 1AMP. The EFEST K1 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 K1 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 adapters you’re taking with you for your phone and/or tablet.    It’ll even charge your batteries using your laptop USB port.
