This is a test of my solar USB power pack with different size solar panels. The 5 watt solar panel did best but probably cannot be left alone to charge the power pack of 8 AA Eneloop batteries. I have configured the pack to have 2 groups of batteries in series. As in other small solar usb power packs, the small 6 v, 250ma panel probably will not be able to effectively charge the batteries. It will however be ok to use the 6 volt panel if the pack is not deeply discharged.
