Efest Slim K1 Battery Charger

Review this product
$7.99

The Efest Slim K1 is a tiny little single-cell charger that lets you charge multiple types of lithium ion cells at a rapid clip, 1 amp.

Efest's Slim K1 is chock full of features to protect your li-ion cell and give it a long, healthy life.

From the smooth durable spring, good for 15,000 travels, to the easy-going slide action to insert your cell, the K1 offers you quick and painless charging. An LED screen with a cell indicates how far along your battery is charged. A steel cathode, chromium-plated, with minimal resistance prevents any loss of energy. 

Your cell will thank you with a longer life if you charge it with an external charger like the K1. You should always charge your cells in an external charger for the best result. Internal mod charging ports don't do justice when compared with external chargers.

All user protections are found in Efest's Slim K1 including: reverse polarity protection, over-charge and short-circuit protection, battery auto-detect, and automatic activation to ensure a good charge.

The Efest Slim K1 can handle these batteries:

  • 10440
  • 14500
  • 14650
  • 16340
  • 16650
  • 17650
  • 17670
  • 18350
  • 18490
  • 18500
