Is it safe to connect a small 5W 5V solar panel directly into a portable power bank? (self.solardiy)

Can I connect a 5w 5w solar panel directly into a 10k mAh portable battery bank safely via USB 2.0, or does it need some sort of protection in-between like a solar charge controller or a schottky diode?

Example of battery bank (except one with usb 2.0 input): https://www.anker.com/ca/products/a1229

Thanks, so safe to just plug any play? Will the battery gracefully handle it when it is fully charged?

battery banks will have their own battery charge controller circuitry that controls the actual charging of the cells. it shouldn't be any different than plugging into the wall as far as battery safety.
