    • An excellent charger that works very well
This charger may be inexpensive but it's actually a really good deal for the price. It provides two charging outputs based on the number of inserted batteries. 1-4 batteries: 500mAh | 5-8: 250mAh If I'm in need of a quicker charge I'll just insert 1-4 and the charging times are half the time of 5-8 batteries. The charging time depends on the capacity of your NiMH batteries. I use 2800mAh AA and 1100mAh AAA EBL high capacity LSD (Low Self Discharge) batteries with this device. I find the output current acceptable and preferable. The higher the current you put into batteries when charging the more damage is done over time and they'll be much hotter during charging - contributing to even more damage. Lower currents, or trickle charging batteries, will allow them to reach their full rated cycle count. While it seems inconvenient to have to wait hours to charge, just remember that it's worth the wait in saved batteries. I'm not sure what the "damaged" battery fix feature does. We don't currently have any "damaged" batteries and the manual states this feature is only for batteries that were deeply discharged beyond the acceptable limits. I guess if this ever happens to us we'll see if that mode actually does anything. This charger heats up a good bit when charging batteries. Keep it on a solid surface to allow the heat to dissipate better. Don't place it on your carpet. Put it on a table or something with good airflow. What I do to compensate for the longer charging times is to have enough batteries on hand that I always have some ready and charged to swap into my devices while I charge the depleted ones. It's common and easy to find LSD (Low Self Discharge) NiMH batteries and I highly recommend people only purchase batteries with low self discharge. For the brand of batteries we use, EBL, we find that the claimed discharge over time is accurate. We use our batteries and swap them often enough that we don't know what that figure would be over very long time frames, but it will vary based on brand and quality. I highly recommend EBL batteries with this charger. They have some of the highest capacities available and a 1,200 cycle count which is above average for their capacity. Well worth the cost and they don't cost much more than cheapo ones. I expect them to last close to the claimed 1,200 cycles, partly thanks to the low charging currents offered by this charger. You can check and measure capacity and charge level with a multi-meter and some electronics knowledge (which I have). Overall this charger is great! Word of caution: don't keep the batteries inserted for long periods of time after they complete charging. A few hours or waiting overnight to take them out isn't a big deal breaker. But don't leave them in their for days or weeks on end. This charger is not designed to handle that and could lead to damage or reduced cycle count. This is also clearly laid out in the manual. My only complaint with this charger is that it heats up quite a bit when charging, especially if charging 8 AA at once. Other than that the smart chip feature appears to be real and works very well. ... show more

    • Don’t think about it, Just Buy It! It’s perfect.
Great Lil Charger! Initially bought Energizer recharger/batteries, felt bad throwing away all those AAA batteries I was using to light up 6 wax flameless candles on my front porch teak table and stairs. But the stupid thing didn’t work, Ugh! The candles barely lit after hours of charging, so annoying! I put the Same Batteries in this recharger and after like a few hours, BAM! 💥 Bright as brand new and lit up as long as new! And btw I thought overall way easier, batteries fit, easy in/out, sits on corner desk, nice lil USB port chord. ... show more

    • POWEROWL 8-Bay Battery Charger – Simple, Fast, and Works Well
I’ve been using the POWEROWL 8-bay battery charger for a few weeks now, and it’s exactly what I needed—simple, reliable, and easy to set up. It charges both AA and AAA batteries at the same time, which is super convenient since I use them in all sorts of devices like remotes, toys, and flashlights. The charger plugs into a wall outlet with a USB cable (it comes with the adapter), and once it’s connected, you just pop your batteries in and let it go. There are no complicated settings or apps—just plug, charge, repeat. One thing I really like is how quickly it charges them. With my Amazon Basics batteries (the ones I use most), they’re usually ready in about 2 hours. That’s pretty fast compared to other chargers I’ve tried that can take twice as long or more. It also doesn’t overheat, even when charging a full set of batteries at once. The indicator lights help you track the charge level, so you know when each bay is done without having to check the screen all the time. ... show more
