Review on 🎮 TechKen Controller Charger with 22600mAh Battery Packs for Xbox One/X/S, Xbox X, and Elite – Compatible with All Xbox One Controllers by Aaron Lewis

Charging station and batteries are very well made and work exactly as advertised. The base is similar to the top of the Series X, which is nice. Batteries hold a charge well and charge quickly. They actually fit into the base and controller in more than one way, and there's no +/- indicator anywhere on the battery itself. I ended up trying both directions on the base (I never pick the right path first) and I tried multiple directions in the controller before finding the right orientation (mentally noting that the text on the battery appears - below). Aside from that initial learning curve due to the ambiguous labeling, which isn't really a big deal to me, I still give it 5 stars and highly recommend it.
