Let me start by saying this charger+battery combo solved my endless 'dead remote control' drama. The pulse-current charging legit juices up AAA batteries in 2 hours flat – I timed it while binge-watching Netflix. My TV remote now has more reliable power than my motivation on a Monday morning.
The 8 independent slots are CLUTCH for mixed-device households. I can charge AA batteries for my wireless mouse while simultaneously powering AAA's for kid's toys. Though pro tip: Those AAA slots require a slight angle to engage (those higher metal clips aren't just for decoration). Once you get the hang of it, it's smooth sailing.
About those 'falling out' complaints? Here's my hack: I keep a small magnetic parts tray nearby to hold loose batteries mid-charge cycle. The included 2800mAh AAs last noticeably longer in high-drain devices compared to my old AmazonBasics set – got nearly 3 weeks in my digital camera before needing a top-up.
The TYPE-C charging is where this shines. While testing, I plugged it into my laptop's USB-C port during work hours and had fully charged backups ready by lunch. The LED indicators are straightforward – red means 'not done yet', green means 'go forth and power things'.
Now the not-so-perfect: Like most NiMH batteries, these do self-discharge about 1-2% per day when stored. For critical devices (think emergency flashlights), I give them a quick 30-minute 'refresh' charge before use. Also, the charger body gets warm during simultaneous 8-bay charging – nothing alarming, but I avoid stacking items on top.
After 4 months of cycling through two sets: The claimed 1200 recharge cycles seems plausible based on current performance. For $35 including both charger AND batteries? This setup has already paid for itself by replacing my disposable battery addiction. Just wish it came with a storage case for the extras!
