EV-PEAK D610AC 100Wx2 8A AC/DC Dual LiPo, LiIon, LiFe, NiCd, NiMh, Pb NiMH Battery Balance Charger Discharger HIGH POWER! 2 Individual 100Watt/8Amp Charge Ports! Each port is fully independent of the other and has its own dedicated power! Using 100Watts/8Amps on a port in no way limits the other port's ability to charge to its full potential! Max the charger out by using 100Watts/8Amps on each port at the same time for a total of 200Watts! AC & DC POWERED! This charger plugs directly into the wall! It also can be connected to a DC power source such as a 12V car battery or a DC Power Supply. WORLDWIDE VOLTAGE COMPATIBILITY! Select between 120V and 240V depending on your locality. The USA and Canada generally have 120V wall outlets. Other countries may use higher voltage, about 204V. This charger accommodates both of them so it is compatible WORLDWIDE! DIGITAL POWER MODE! Each Port can act as a power supply! Use this function to power external items such as a pit light, tire truer, motor checker, charger, or anything else that runs off of DC power. Both the Voltage and Amperage are adjustable to suit the needs of the connected device. Amperage adjustable from 0.1A-10.0A. Voltage Adjustable from 3.0V-24.0V EXTRA FEATURES: Lithium Cell Check displays the voltage of your cells without having to be in charge mode! Balance Charge mode balances the cells in your Lithium packs for optimum performance and safety. Storage mode charges/discharges your lithium batteries to about half charge for extended storage times. Discharge mode for all battery types including Lithium and Nickel types have adjustable end voltage so you can determine the final discharge voltage of your cells.
