I need help w my River 600 & Dokio 220W panels

[aMUSEd]

Thank you for reading this. I bought these 220W panels from Amazon and when I connected them to my Ecoflow River they drained the battery. I returned them and ordered some on eBay, the same panels. There's not been much sun, raining at times. But when I hook them to the River 600, it doesn't even show anything is connected. With the previous panels, the input icon was lit. Not this time, there's nothing. I then tried hooking the panels to the controller and tried to charge my earbuds, again, nothing. No lights, nothing. I feel stupid asking this but is there an off/on switch on the solar panels?
I've triple checked the connections and will send pictures if you need.
TYVM for your help.

Hmmm... it might help if we had some links to the items you have/are using. Otherwise it is a bit difficult to examine if there are specific details about each product, that might have caused the results that you are describing.

Have you recharged the unit via Plug to household power ?

Physically.....how did you hook up the Dokio to the River.........Dokio often uses the rubber Zamp/SAE connector......Polarity ?

and in the limited description on the RIVER sales site it lists " Max. Solar 200 watts.....goes on to say w/two 110 watts....." ?

Yes. It charges easily both 110 and via cig lighter adapter,
The panels also charge my RockPals 300 battery but I had to use the controller. So I tried using the controller on the River and it doesn't even register that it's receiving.
I wonder if the other panels, the ones that drained the River, ruined something.
Yesterday it was cloudy, max input was 45w, but the River still wasn't feeling it.
I have trouble with the different names of the connectors. I've switched out different cords, bought longer 12 gauge cords. I'm sure I'm properly connected.

I thank all of you for your input.
