Battery Charger With Voltmeter Ammeter DC-DC step-down CC/CV Voltage Current
display ModuleHighlights :
Contains the voltmeter, ammeter, power meter, USB interface for
charging the digital products.Note:
1.When you use the product, the module inputs and outputs to be
isolated from ground.2.USB output voltage is consistent with the module, not a fixed 5V
output. When charging for digital equipment, make sure USB output voltage is
5V.3.Some customers report: “The module can not adjust the output
voltage is always equal to the input voltage.” When you encounter this problem,
please counterclockwise rotation of the “voltage potentiometer” 10 laps or
more, then use the module you can adjust the output voltage. Because the
factory default output voltage of about 20V.

DC-DC 5V12V24V Automatic Step Up and Down Regulator Module
Stabilizer 5A/80W With voltage display
Input voltage: DC 4.5 ~ 30V Do not reverse or reverse, or
will be damaged
Output voltage: DC 0.5 ~ 33V
Maximum output current: 5A
Maximum output power: 80W long continuous work Please
strengthen the heat, it is best to leave a margin
Conversion efficiency: 91% (measured at 12V input, 19V
output 2A)
Module size: 78 * 48 * 22mm (length and width)
Note: This module is a regulator module, without constant
current function, can not output directly to the battery or LED (that is, the
output can not directly connected to the battery, such as with the battery
itself with a charging circuit can be connected, such as red charge Po, LED
Drive there is no problem,).
