This field is required
  • Operating mode description
  • With key off function, and reduce power consumption.
  • Power state can be freely defined
  • Input and output voltages can be displayed alternately
  • On/0ff output status, high level means output off, low level means output on. (note: high level (3.3v), the maximum output current 5mA)
  • Output voltage mode:Boot default display it, LED indicator off
  • Input voltage mode:Press button switch to it , LED indicator on
  • Alternating mode:Press button again input/output voltage alternately display (3s). Press button again, switch to output voltage display


  • In+:                                    Input positive
  • In-:                                    Input negative
  • Out+:                                  Output positive
  • Out-:                                  Output negative
  • weight:                                 20g
  • Dimensions:                             62 *26 *14mm(length*width*height)

  • Display color:                            Red/Green/Blue
  • Input voltage:                            4.5-28V
  • Output power:                            15W maximum
  • Output voltage:                           1.3v-25v (step-down mode, the input voltage must be 2v higher than the output voltage)
  • Output current:                            1.5A
  • Ripple frequency:                         About 150KHZ
  • Voltage meter accuracy:          ±(5 ‰ +1 digit)
  • Static power consumption:    Typical about 20mA

Stop working mode
Keep pressing the button until the monitor does not display numbers ( long press more than 4s) and release the button. LED lights and module shuts down. The output voltage is zero. At this time, it does not perform memory function. ON / OFF output high level (3.3V), then the static power consumption is about 2mA. Click the button, the module starts working again.

★★★★★ Great bag
Purchased this for my 23 year old daughter in the butterscotch color. Great versatile color. She loves the size -- perfect for day or going out at night. Chain can be double to shorten for nighttime and left long to wear as a crossbody during the day.
