Okay, so I've been using these Mupoer AA rechargeable batteries for a while now, and here's the tea.

First off, the capacity is no joke. They last just as long as my expensive name-brand ones. I was skeptical about the 2800mAh claim, but they actually hold up pretty well in my wireless keyboard and gaming controllers.

The eco-friendly aspect is a big win for me. No toxic stuff? Yes please! I feel slightly less guilty about my battery consumption now.

One weird thing though - why don't they say 'rechargeable' on the batteries themselves? Had to double-check my order to make sure I didn't get regular AAs by mistake. That's kinda odd.

Charging is quick and they seem to hold charge when stored. Haven't had any leaky battery disasters (yet), which is always a plus.

Are they perfect? Maybe not - someone mentioned testing at 2100mAh instead of 2800, but honestly for the price, I'm not complaining. They're definitely better than constantly buying disposables.

Final verdict: Solid budget-friendly option that gets the job done. Would buy again!
