International Power Adapters By QCCAN

• The maximum output current: 2A; The input voltage: 2V ~ 24V
• The maximum output voltage: 28V; Efficiency: ?93%.
• Method of use: The module of the IN+ and - after 2~24V, IN adjusting the potentiometer can adjust output voltage, output voltage is greater than the input voltage.
• Note:1) The input voltage should not exceed the maximum input voltage; 2) The peak current output current does not exceed 2A.
• Package included:12 x MT3608 DC-DC step up module.

• 1.4 in 1 Charging / Discharging / Lithium Battery Protection / Battery Level Indicator Module. Lithium battery protection function: over-current, overvoltage, over-temperature, short circuit protection.
• The first time the load is connected, the output is automatically turned on. If the load is less than 50MA, The output is turned off after 30 seconds; if the load is greater than 50MA, the output is continuously turned on.
• In discharge mode (The charging mode KEY function is invalid), trigger the KEY port once to open the output; continuously trigger the KEY port twice to close the output.
• Applications:It can be used for Car charging retrofit; Driving recorder power supply; Mobile power/ charging treasure; Portable devices such as mobile phones and tablets, household power supply, fast charging adapter, etc.
