dc power supply 5v 2a power bank
1. This system is equipped with intelligent control system of microprocessor and special control algorithm, which is small DC power system designed for power supplying of outwork, home use, camping in remote area and power shortage region, and so on.
2. The circuit uses a highperformance, highprecision 10bit ADC MCU as the master, with battery overcharge, over discharge, overload and short circuit protection with unique electronic antireverse protection, lowpower standby, USB output, light output overload protection, charging, discharging separate functions.
3. This unit is a pure DC output system, one USB 5V/2A output port, one DC 5V/2A output port, one DC 9V/2A output port, one DC 12V/2A output port, one DC 15V/1A output port, and one DC 24V/1A output port.
1. Using SCM as the master, to achieve a battery charge and discharge of the intelligent control, overcharge, over discharge protection, short circuit protection, when the load is overloaded, the system will automatically shut down, automatically return to normal after a few seconds, effectively extending the battery life, battery over-ischarge and voltage rise control.
2. Ultra low power standby function: When ON / OFF switch is in the OFF state, the product enters a low power state.
3. USB Output: When charging mobile phone/MP3/MP4/digital camera, the output current reach above 5V2A.
4.Charge and discharge independent function: charging, discharging without disturbing each other, can realized discharged while charging.
5. Charge and discharge indicate function: monitoring system charge and discharge status at any time, when it charging, the charging indicator turns red, when it discharging, the working indicator turns green, when it under voltage , the working indicator turns red.
6. When this unit charge by solar or adapter, please turn off the ON / OFF switch, don’t turn on any load in order to reduce the charging time.
7. This product has overcharging and short circuit protection function(battery protection, it need be activated by charging), when it undervoltage, indicator light turns red.
