There was one on eBay, there are ways to get Kobo to replace but they need receipt for 12 months.

They will offer coupons to buy newer unit.

WHY TF did they make the charge port so weak, so we can break over time and buy new device. F-that. Anyways that's what we did.

Still looking for affordable USB port replacement, some used units cost as much as the replacement parts.
