3.7v 9V 5V 18650 Charging Step-Up Boost One Adjustable Module 2A Micro USB Type C

● Debug before use, the default output is about 9V

● Input voltage 4.5-8V

● Continuously adjustable output voltage 4.3-27V

● (Above 4.3V and below 27V, any voltage can be output, you can adjust it yourself

Turn up the pressure counterclockwise)

● Charging voltage 4.2V Charging current Max 1A

● Discharge current The maximum 2A output current must be calculated by yourself

● Output reference maximum current 5V 1.4A, 9V 0.8A, 12V 0.6A

● Quiescent current is about 0.5 mA

Overcharge protection

● Over-discharge protection None (it can also be said to have, 2V cut-off boost

● But if the output is not blocked, the output still has 2V)

● Cut-off boost 2V, depending on the situation, whether to add a protection board

Size 3.3X2.3X0.9

For example, the VIN+ terminal is connected to a 5V solar panel and the BAT+ terminal can output 4.2V to charge a 3.7V 18650 battery.

The OUT+ terminal can output an adjustable voltage. You can adjust as much as you need.

Can be used for multimeter to recharge lithium battery

Large quantity can be customized for fixed output

Adjustable by default
