HW-357 J5019 3.7V 9V 5V 24V boost module Charging Module

HW-357 J5019 3.7V 9V 5V PCB Adjustable Step Up 18650 Lithium Ion Battery Charging
Discharge Power Bank Charger Module
Specification:
Input voltage: DC4.5-8V
Output voltage: DC4.3V-27V (anti-clockwise rotary positioner)
Output current: 2A max.
Charging voltage 4.2V, charging current 1A
Size: 33 * 23 * 5mm / 1.29 * 0.9 * 0.19 ”
Packing weight: 5g
Operation:
Before use and before debugging, the output Default is about
9V. Input voltage: 4.5-8V
The output voltage can be continuously adjusted 4.3-27V
(More than 4.3V , less than 27V , can produce any voltage, voltage reversible adjustable clockwise)
Charging voltage: 4.2 V, charging
current 1A Calculate discharge current 2A output current
Maximum current output reference 5 V 1.4A, 9 V 0.8A, 12V 0.6A
The static current is approximately 0.5 mA.
No over-discharge protection for overload protection (2V surge boost is possible, but 2V output is not yet locked)
2V cutter lift, depending on situation, if board needs to be added Protective
For example, the 5V solar panel with input + BAT + terminal can take out a battery from 4.2V to 3.7V
18650 and adjust the adjustable output voltage of the terminal.
Can be used for multimeter and lithium battery recharge
Note:
There may be 1-3mm difference 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 understanding.
