Jackery 290 + HF 100w panel - average sunny day charging

Its no problem to get the Jackery 290 charged up fairly quick with the Harbor Freight 100w panel - it recharges the Jackery battery with a 60w input which equates to about 20% per hour, at least up to the 90% mark when the Jackery starts dialing down the input wattage automatically. Very different outcome from our cloudy day results.
