Review on 🔋 EBL Rechargeable Battery Packs for Xbox One/Xbox Series X/S - 2×2800mAh Xbox One Controller Battery Packs for Xbox One/One S/One X/One Elite by Chris Mickens

This was best value for money, the batteries themselves feel good and work as expected. I saved money after just a few weeks of use. Cool charge indicator that is easy to read. I'm skeptical of the 2800mAh as most of the others here seem smaller (around 1800-2500mAh) but I could be wrong and it definitely lasts a few days to a week depending on how many games I make.
