Just purchased this Solar Generator Combo! So far seems to be excellent! Charges well with full sun. Charges at the advertised 120 watts from the panel in full sun! FYI….don’t bother with upgrading to the PV 200 panel with this generator as it cannot handle the higher amperage of that panel and consequently will NEVER charge at that rate! You will be throwing money away if ya go with the larger panel….I think it tops out at around 165 watts with that panel. The 120 will charge the EB70s to 100% with the PV120 over about 7–8 hours of full sun. Blessings!
