One of the most versatile chargers on the market, the Klarus K1 Smart Charger is the perfect combination of power and portability. Less than 5 inches in length and weighing just over 2 ounces, this single-bay charger is able to charge a wide variety of Li-Ion batteries, such as 18650 and 16340 cells, as well as AA, AAA, AAAA and C sizes of Ni-MH and Ni-Cd batteries. The K1 features an easy-to-understand LED display where the user can monitor the charging progress of the inserted battery and allows him to choose between a 0.5 Amp and a 1.0 Amp charging current. The sophisticated charger also features an auto-activation function for short-circuit protected Li-Ion batteries that have been over-discharged, as well as -DV/dt Control technology that allows Ni-MH and Ni-Cd batteries to charge more fully. Crafted from flame-resistant ABS plastic and designed for optimal heat dissipation, this charger is as safe as it is effective!
