5V Boost Converter Step-Up Power Module Lithium Battery Charging Protection Board LED Display USB For DIY Charger

Product advantages:
1. Ultra-small size: 2.2*1.8*1.0CM almost all mobile power shells can be easily installed.
2. Complete functions: Most of the modules known as mobile power sources on the market have a single function, such as single boost, single charge, and single protection; and this product includes boost, lithium battery intelligent charging, lithium battery undervoltage protection, and output short circuit protection. , Android mobile phone charging identification circuit and other mobile power functions.
3. Ultra-low quiescent current, the power consumption of the whole circuit is only 0.1mA when no load is connected; no manual startup is required, long-term standby state when no load is connected, and the power consumption is only 0.1mA.
4. The circuit integration is high, the peripheral circuit is simple, so the reliability is high.

Technical data:
Charging voltage and current: DC5V/1000mA (red light on when charging, green light on when fully charged)
USB output voltage and current: DC5V/1200mA (please do not connect equipment with a current exceeding 1200mA for a long time)
Charging port: Micro USB

Note:
1. The module is a kind of electronic components, it can only be used by friends with electronic foundation, otherwise it may be damaged by improper operation!
2. Please do not use the output device with more than 1200mA, otherwise the circuit board will be easily damaged.
3. Please connect the B+ and B- ends of the battery, the polarity must be correct, the reverse will burn the chip.

Note:
What capacity battery is suitable for input connection?
Answer: For discharge, the larger the battery capacity, the better. For charging, the larger the capacity, the higher the requirement for the charging circuit and the longer the charging time. For the best experience, connect 2-3 2600mA 18650 lithium batteries the best.
