I2 Nitecore Intellicharger I2 Li-ion / NiMH battery charger is a universal, automatic smart-charger compatible with almost all types of rechargeable batteries thus eliminating the need to own several chargers. Capable of charging 2 batteries simultaneously Each of the four battery slots monitors and charges independently Automatically identifies Li-ion, Ni-MH and Ni-Cd rechargeable batteries, including 26650/ 22650/18650/17670/18490/17500/17335/16340(RCR123)/ 14500Features three charging modes (CC, CV and Trickle Charge) Automatically detects battery status and selects the appropriate voltage and charge mode 3 Color LED displays charging progress for each battery Automatically stops charging when complete Features reverse polarity protection Designed for optimal heat dissipation Certified by both RoHS and CEThe i2 is restricted to charging Li-ion, Ni-MH and Ni-Cd rechargeable batteries only. Never use the i2 for other types of batteries as this could result in battery explosion, cracking or leaking, causing property damage and/or personal injury.Input voltage: AC 100~240V 50/60HZ or DC 12VInput power: 10WOutput voltage: 4.2V ±1% / 1.48V ±1%Output current: 0.5A ×2Dimensions: 132mm × 70mm × 35mmCompatible with:Li-ion: 26650, 22650, 18650, 17670, 18490, 17500, 17335,16340(RCR123), 14500Ni-MH / Ni-Cd: AA, AAA, C
