“Bright sunny day today, measures around 165,000 lux (using my Galaxy S5 and “GPS Status” app on phone) just past solar noon in southern new england. Today I used 2 Drok USB power meters, one in each output port and two devices (phone and battery pack) to pull maximum power from the panel. I was pleasantly surprised to see a total charge power of 1.9 Amps!!
