Okay, so I took a gamble on these POWEROWL batteries after seeing mixed reviews. Here's my honest take after using them for a month.

First impression? They're CHONKY. Like, noticeably heavier than my old Energizers. That made me hopeful about the capacity.

Good news: They last FOREVER in my kid's toy cars. We're talking 3-4 play sessions before needing recharge. Major win compared to the 1-session wonders we used before.

The charger? Cute but basic. No fancy indicators, just a red light that turns green. Takes about 6 hours for full charge in my experience.

Now the weird part - they work amazingly in some devices (toys, flashlights) but terribly in others (my smart thermostat ate them in 2 days). No idea why!

Pro tip: They absolutely need 3-5 full charge cycles to reach max potential. First use was meh, but by cycle 3? Night and day difference.

Would I buy again? Probably - but only for high-drain devices. For low-power stuff, they're overkill.
