Bob, that unit has a maximum available amperage of 4.5 amps. You're only going to be drawing 1.0 amps, so you're good to go. You could probably run that thing for a couple of days continuously with that much available power (16,750mAh). My pack is 13,000mAh and supplies 1.0 or 2.1 amps and it powers my LabRadar all morning with plenty of power to spare.Just got my lab radar. Manual says battery back of 5V at 1 Amp. Is your pack too powerful?
