LiitoKala Lii - Battery Charger aims to supply power for your rechargeable batteries.It also provides 4 kinds of current modes for you to choose ( 2A max. current meets quick charging demand ). Multiple circuit protections are for worry-free use.Main features:4 battery slots and 1 USB port4 battery slots are powering Li-ion batteries, Ni-MH / Cd, ferric phosphate lithium cell. Meanwhile, the USB port charges for your phone, iPad and other USB equipment.Intuitive power level displayLED indicators directly show the charging progress: 25pct, 50pct, 75pct, 100pct. Check it at any time.4 charging current modesFour charging current modes: 500mA / 700mA / 1000mA / 2000mA, free to switch ( 2000mA current mode is fixed only on the fourth slot ).5 safety protectionsMultiple protections: overcharge, over discharge, short circuit, broken battery identification and polar reverse inspection. Safer for use.Charging Cell Type: Lithium Ion,Ni-MH Compatible: 14500,16340 (RCR123),17500,17670,18350,18490,18650 Batteries slot:Input: DC 5V / 2AOutput: 1.42V, 4.2V + / - 0.05V, 3.65 + / - 0.05V, 4.35 + / - 0.05VOutput Current: 2000mA / 1000mA / 700mA / 500mAStandby current: less than 15mAUSB:Open-circuit voltage of USB output: 4.9 - 5.3VOutput: 1A / 5VOpen-circuit current: less than 1mACut-off voltage for discharge protection: 3.0 + / - 0.1VPackage Contents:1 x LiitoKala Lii - 402 Battery Charger1 x USB Charging Cable ( 48cm )Note:The USB 2.0 is for charging USB device, micro USB port is the current inputWarm TipsOnly the fourth slot can check the power when the battery is not chargedIt is not allowed to select the current when you put four batteries in at the same time, which is the fixed value of 500mAIt is allowed to select the current when you put less than four batteries in at the same time. At this point, the charger needs to connect 5V power
