I got some good rechargeable AA for my controllers about three years ago and will never go back. I have one pair more than controllers and I always have a charged pair read to switch out if needed.
I got 2500mAh batteries from duracell and the charge lasts for days of activity on my xbox controllers. Longer than my PS4 controllers with integrated battery for sure.
It’s a brillant device, I often use it more than my PC.
It gives me the feeling that playing the Gameboy as a kid gave me. The switch would only make my hands cramp because the controls are only made for small hands.
