Giới thiệu 18650 Li-ion Battery Boost Charger Module 3.7V 9V 5V 2A Step Up Module Board

Specification:
Input voltage: DC4.5-8V
Output voltage: DC4.3V-27V (positioner counterclockwise rotating boost)
Output current: 2A MAX
Charging voltage 4.2V, charging current 1A
Size: 33*23*5mm/1.29*0.9*0.19''
Packaging weight: 5g

Operation:
Before use and before debugging, the default output is about 9V.
Input voltage: 4.5-8V
Output voltage can be continuously adjusted 4.3-27V
(Over 4.3V, below 27V, can output any voltage, reversible clockwise adjustable voltage)
Charging voltage: 4.2V, charging current 1A
Calculating Discharge Current 2A Output Current
Output reference maximum current 5V 1.4A, 9V 0.8A, 12V 0.6A
The static current is about 0.5 mA.
There is no overdischarge protection for overcharge protection (2V cut-off boost is possible, but 2V output is still not blocked)
Cut-off boost 2V, depending on the situation, whether to add protective plate
For example, VIN + BAT + terminal of 5V solar panel can output 4.2V to 3.7V 18650 battery charging OUT + terminal output adjustable voltage need to be adjusted.
It can be used for multimeter and recharging lithium battery

Note:
Please allow 1-3mm differs due to manual measurement.
Due to the different display and different light, the picture may not show the actual color of the item. Thanks for your understand.
