Example
Step up battery power 4V to 9V for Multimeter
Step up battery power 4V or 5V USB power to power 6V DC blood pressure unit
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. Test only 250mAh
Calculating Discharge Current 2A Output Current, test only 1A or lower
Output reference maximum current 5V 1.4A, 9V 0.8A, 12V 0.6A
The static current is about 0.5 mA, test 0,6mA.
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
