Charging Omni 20+ 20000mah Laptop Power Bank Portable Charger with Goal Zero Nomad 7 plus (USB A)
I have a Goal Zero Nomad 7 Plus solar panel charger. It only has a USB A (female) output. I just purchased a Omni 20+ 20000mah . Although the Omni 20+ has USB A ports, only the USB C ports (and the DC port) on the Omni 20+ can be used for input/charging. If I get a USB A to USB C adapter will I be able to charge my Omni 20+ 20000mah with my Goal Zero Nomad 7 Plus? Thanks for your help!

I got this response from Omnicharge support and it seems I'm out of luck:
"Generally, when charging from solar, we recommend using a higher-wattage solar panel straight to the DC barrel input port, as charging via USB would be excessively slow and not practical. For charging Omni 20+, we recommend at least a 20W solar panel.
Since Goal Zero Nomad 7 Plus solar panel has only a 7W output, even if you get USB-A to USB-C adapter, it wouldn't have enough power to recharge the Omni20+."
Seems a little weird since my Goal Zero Nomad 7 Plus is able to charge up my little Goal Zero Flip 20 power bank. I would figure it would at least give some charge, even if very slow.
