This is the lowest I've ever seen on the wireless charing version of these airpods. If you are in the market, having the case charge via Qi charging is a great feature!
From Apple:
Microsoft has a great deal on the samsung wireless charging brick. Its a normal charger but also has a qi charger on it, so you can charge your watch or headphones. Any Qi device should work.
From Samsung:
Go the distance with the Wireless Charger Portable battery, engineered for on-the-go power and wireless charging. Take it along for the ride as a 10,000 mAh portable battery pack, or charge up to two devices at once wirelessly while it’s plugged in. Plus, it’s Qi certified, meaning it’s primed to accommodate any Qi-compatible products, including Samsung Galaxy S10, Galaxy Note9, Apple iPhone 8, iPhone X, and Google Pixel 3.
