DescriptionElectrical performance:Input voltage: 100-240VACCharging voltage: 42V DCCharging current: 2ADC Interface: 3P balance the car-specific interfaceProduct size: 138 * 60 * 36mmRated power: 84WPower LED: charging red light， full of green changePlug: US Plug. If you need EU/AU/UK Plug，pls leave a message within 12 hours. Features:With a perfect over-current， overcharge， short circuit protection， stoped.IC control and accurate charging voltage， will not overcharge， let your battery a lot longer.Solid materials， abandoned the low-end power supply transistor， single IC built-in power tube practiceDual IC integrated circuits， drive an external MOS. So very foot power margin， even under extreme conditions without failure.Standard wire， all the raw materials production， the original IC， PC shell material.All the raw materials used in the upper original， small defective tape and have a stark contrast!Overvoltage overcurrent complete， stoped! ! Not to hurt the battery!Working environment and protection functions:Overcurrent protection: Yes， output current * 130%Overvoltage protection: Yes， output voltage * 115% - 135%Short circuit protection: Yes， do not damage the power output short circuit， output short circuit when released， power is still normal output.Humidity: 20% -90% RHWorking temperature: -20-60 ��Storage temperature: -40-80 �� Package:1* High Technology Charger for Smart Self Balancing Balance Electric Scooters Battery Charger (US Plug，The Scooter is not Included)
