1.TR-007 charger is nonlinear constant current and constant voltage PWM intelligent rapid charger.
2.TR-007 charger can make the battery keep stable charging current in a certain voltage range.it is big current style charger,it will stop charging itself when fully charged.
3.The charger has three modes (H is big charging current, L is a small charging current, O for USB charged external mobile equipment) change-over switch,it can change the switch function as needed.
(1).When the switch position is H mode charging the battery under 2.5V,the charging current is 850mah - 900mah.When the switch position is L mode charging the battery under 2.5V,the charging current is 425mah - 450mah.
(2).When the battery voltage is 4.0V,charging mode changed into 800 pulse type. Until full of electricity.whose rate is 99%-100%.
4.The charger inside using PWM control mode charging,it is high voltage and big current constant current charging.it can achieve the purpose of rapid charging.
5.the voltage of the battery should ensure above 0.5V,if the battery's voltage is lower than this voltage,this charger can't charge the battery,it should use other way to make the battery's voltage above 0.5V.then use this charger to charge the battery.
(1).put the adapter on 220 v AC power supply,DC plug put into the charger DC jack,the charger green power indicator will light up,then put the battery into the charging slot,good contact for its electrode and charging piece,the indicator will become red.Indicating that the battery is being charged.
(2).When charging, due to the charging current is bigger, the charger will have a certain temperature,it is a normal phenomenon.
(3).When the battery is full of power,the indicator will change from red to green,indicating that the battery has already been filled with electricity.
7.The charger is with anti battery inversion circuit,it can protect the battery and charger from damaging because of battery inversion.
8.The charger can charge 14500, 14650, 17670, 18500, 18650, 18700, 22650, 25500, 26650 type batteries.
9.Charging time: usually two pieces 18650 2000mah battery can be fully charged only in four hours.
10.The charger can only charge the 4.2 V lithium battery.
11.The charger can use the battery full of power as USB charged external mobile equipment,making this charger become mobile power supply,switch the charger to O mode,now the USB indicator light will light up,put the USB2.0 data line plug into the charger's USB socket,so it can charge mobile devices through the data cable.
Note: when the charger is used as a mobile power supply,forbidding to charge the battery in the slot at the same time.
TR-007 charger is nonlinear constant current and constant voltage PWM intelligent rapid charger,it can charge 14500, 14650, 17670, 18500, 18650, 18700, 22650, 25500, 26650 type batteries.At the same time,it also can make this charger become mobile power supply,charging the external electronic equipment!
Convenient and quick operation brings different intelligent experience for the user!
