Made some indoor measurements yesterday 11/21/2016 on my A119 with no GPS connected. A little late but here are the details:Anyone know the power requirements of this A119 cam? I have a usb volt/amp meter I am gonna hook up and see what its pulling.
- Measurement: A119 average current over a 1 to 1.67 hour period (actually Amp hours divided by hours), and voltage.
- Power source and cable: Zendure A2 +5Vdc power bank and supplied A119 short cable.
- Measurement device: Keweisi Model KWS-V20 inline USB Volt/Amp meter at the power source.
- A119 Mode: Record.
- Measurement 1 - LCD screen OFF: Amps 0.416 A averaged over 1 hour period, Voltage 5.13 Vdc.
- Measurement 2 - LCD screen ON: Amps 0.459 A averaged over 1 hour 40 minute period, Voltage 5.13 Vdc.
- Power consumption calculates to be 2.13 Watts LCD off and 2.35 Watts LCD on.
Able to read to 3 decimal places but doubt accuracy is that good. A month ago, measured about 0.08 Amp less with same power source and voltage (5.13 Vdc); with GPS, don't recall mode or cable, and eyeballed average from instantaneous current. Lots of variables so even a good measurement is ball park.
Regards,
