Just got these POWEROWL rechargeable batteries and I'm seriously impressed! The 2800mAh capacity is no joke - my Xbox controller lasted through an entire weekend gaming marathon without dying.

The 8-slot charger is super convenient with its USB-C/Micro USB options. Love that it shows charging status with LED lights (green = good to go!). Though warning: the battery orientation is a bit confusing at first - had to check the manual.

What really surprised me? These hold charge forever! Left some in my drawer for 3 weeks and they still worked perfectly in my flashlight. No more emergency store runs for disposables!

Only gripe? The charger doesn't come with a power brick. Had to use my phone charger, but it works fine. For the price and performance, this kit is an absolute steal. 10/10 would recommend to anyone tired of buying disposable batteries!
