In the Costco app, in the warehouse tab in the bottom navigation bar, you can search for inventory and price of a particular item. You can compare prices and availability if there are multiple stores near you.

During the last discount, price in-store was the same as online.
I bought in warehouse for $220 each.

Kinda interesting since there is actually two 2pcs 5000mAh RAPID Magnetic Power Banks included. Yet only one slot on the River 3 Plus for storage.
But my currently 5000mAh RAPID Magnetic Power Bank does have issues to support Qi2 15w on iPhone 16 Pro, Apple shows warnings it's slow charging(~5w) instead of 15w claimed to be.

I would say it is for the simple fact you get the portable phone chargers. I have a River 3 Plus that powered all 3 of my kids iPads on an 8 hr drive just fine with some room to spare when we reached the end of the trip. It is also now being shipped back to EcoFlow for an error code that popped up on the same trip though.

Contact EcoFlow and tell them the issue if it is under warranty.

Gonna try to flip my river 3 plus I got for $188 out the door for $250-ish, but would probably take $225 for effectively a cash neutral upgrade. I think there were some hardware revisions on noise, a better AC sine wave/etc/ on this model compared to the non wireless charger river 3 plus which make it sound like better hardware.

Plus the wireless phone chargers and costco return policy. It's gonna be a win for me.

It should be communicating over qi2, I'm seeing 15W draw on my unit. I believe it could slow charge due to heat. That's an inherent issue with wireless charging especially with a power bank that itself heats up
