Yes - - that’s what Syed said in one of his posts. I never saw a solar panel with a USB connector either, but I’m not a big fan of solar panels.
The way I used the 2 solar panels was to plug one (the shinny one) into the bayonet, and the dull one into a USB to Micro USB charging cable and then into the micro USB port on the Lantern.
As I have said, the combination of the 2 solar chargers can’t keep the internal 5,300 mAhr battery charged to run the Lantern 24/7, so I use an external 2 amp wall wart to operate my Lantern. Ken
