Wireless Charging Case Replacement Compatible with Airpods (Charger Case Only, Airpod not Included, No Bluetooth), Earbuds Protective Cover with 450mAh Built-in Battery Charge 5 Times (Red)

This works well and is wireless charging as a bonus.

If you are looking for a second charger to leave at the office or for emergencies, this charger is probably fine, but I lost my Apple charger and bought this to replace it. Sadly, my airpods have not worked correctly since. The pods work intermittently, the don't sync properly, they constantly try to connect to my phone when in the charger, the battery level goes up and down since they are always connecting. Also the charging case does not hold much charge, so the claims of 5 charges is likely false. Again, great backup, not great replacement to the real thing.
