myCharge Portable Charge 10050mAh

I am selling a used, in good-condition myCharge portable charger. It has USB-C & an Apple lightning adapter. In my experience, it has charged my iPhone 13 Pro 1.5 times on one full charge.
This item is selling on Amazon for $79.99 (new). However, I’m willing to let this go for $50, considering it is a used item. I’m open to offers, please send them.
