You can now purchase a 2nd Gen AirPods Pro USB-C standalone case.. for $99
Yes, it is possible to misplace your AirPods case accidentally. If this happens to you, the good news is you don't have to purchase another pair of AirPods to replace your lost case. Apple now sells a standalone USB-C charging case for the second-generation AirPod Pro for $99.
I know what you're saying; that is a steep price for a charging case. But you might be one of the few who use an AirPod Pro Thunderbolt Lightning charging case and want to switch to a USB-C charging accessory. Also, the case is MagSafe compatible, Apple's latest wireless charge technology.
Released to market earlier this year, the USB-C AirPod Pro is preferred by many consumers over the Lightning variants. They are dust and splash-resistant. The USB-C case alone has a very respectable IP54 rating.
The USB-C, the 2nd generation AirPod Pro standalone charging case, is now available on Apple's website, listed under accessories.
