Question - Pilots - Do you know how much power your GoPro, Mobius or other USB battery charged devices are consuming? - Do you know if these USB charged devices/LiPos are loosing efficiency or if their cells are failing and will catch you out on your next film project in a remote area? - Dont be caught in the air with a flat GoPro or a Flat Mobius - this simple inline power meter gives "TOTAL milliAMPS" of a charge cycle - CAPACITY - can tell you the health of any LiPo 3.7 cell charge by a USB cable or PC - it can also tell you the accuracy of the power 5.00v for USB.
You can also see the "CHARGE RATE" so devices which claim to supply USB 1 amp or USB2.1 amps can be tested and by observing a trickle charge like 35ma you know the charge cycle is almost complete and can be disconnected
We recommend to disconnect it when not being used - although it uses very little power (20ma) in its off-line state - but will eventually shorten its life if plugged into your PC for hundreds of hours.
