Should I Buy It?
The POWEROWL 8 Bay AA AAA Battery Charger is a worthwhile consideration for those looking for an affordable and versatile battery charger, offering the added convenience of independent charging slots. However, be aware of its noted drawbacks, including quality concerns and inconsistent performance. If these potential issues align with your tolerance for risk, this charger might be a suitable purchase.
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.

Excellent price-to-quality ratio. Iβve been using this charger with LightTalent Ni-MH AA 1000mAh 1.2V batteries and it works really well. Fast charging: I usually charge all 8 batteries at the same time, and the charging time is about 40 minutes, which is very efficient. Independent slots: Each battery charges individually, so thereβs no need to worry about mixing partially charged ones. Easy to use and reliable: Plug it in via USB, insert the batteries, and it just works β simple and effective. A great charger for daily use. If you need to recharge multiple batteries quickly and reliably, this is an excellent choice, especially for the price.

I really wanted to like this charger. I have their rechargeable batteries and have been happy with them but this has not been a pleasant experience. If batteries are really dead, the charger won't charge more than a couple at a time and now, after owning it about a month and a half, it no longer charges more than 2 at a time. If I put more then 2 batteries in it, every battery begins blinking red and they will not charge. I've even put in batteries that I only I've recently charged and I know they're not even half dead. The same thing happens. I've switched charging cables, switched outlets. Tried anything I can think of in case the outlet just wasn't strong enough. Nothing has fixed this. I wrote the company to see if it's just defective, but I'm kind of over this charger. I ordered an EBL battery charger. It comes with an actual power cord (not a USB to micro USB cable) so I feel like that one might be more reliable. I'll find out soon. Edit: the company was very responsive and sent me a new device, as there was clearly something wrong with mine after only owning it for a month and a half. The new one is working right now. I did end up ordering the EBL brand of battery charger and I'm much happier with the cord on that one versus this one so I'm rating this working charger a 4 star because the cable is a weakness.

Good product. You have to provide your own adapter for electric access.
