Super material:
It is made of electronic accessories, nickel plating on surface(anti-oxidatioan), inner conductor: pure copper.it is long lasting and durable for you to use.

Allow discharge while charging. (Note: At this time output voltage 4.7 / 5V).
A large area of copper and dense vias enhance heat dissipation. it has current limiting, short circuit and over temperature protection. Even if the output is short circuit, it will not burn out the module and it is safer.

Package included:
8pcs x DC adjustable step-down module.

• ❃❃ MCU users, if you accept a small load KEY can be connected to the microcontroller about 20s to provide a low level allows the module to continue working. Trigger mode: low level trigger (ground).
• ❃❃ 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 output opens automatically at the first time the load is connected.If the load is less than 50MA, automatically close the output after 30 seconds
• If the load is greater than 50MA, the output opens automatically.
• ❃❃ High Power High Efficiency: Discharge efficiency up to 96%. 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.
• ❃❃ Can be applied to solar panel turning to mobile phone charging, car charging retrofit, driving recorder power supply, household power supply, intelligent plugging transformation, fast charging adapter, etc.
