POWEROWL 8 Bay AA AAA Battery Charger, USB High-Speed Charging, Independent Slot, for Ni-MH Ni-CD Rechargeable Batteries, No Adapter

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: 250mAhIf 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.

These AA/AAA rechargeable battery chargers work very well, I bought a 2nd one! Great price. The thing that sets these apart from many other chargers is you don't have to charge in pairs or fours. Many work that way and cannot charge one battery or an uneven number. It is a bit slow when using a USB port. There is no yellow indicator to show charging progress, so the led lights go from red right to green, but that's not a problem. These are so easy and simple to use! Recommend 👍🏼

UPDATE... Customer Service reached out and the problem has been resolved!! I'm thrilled because I really do like this charger! I am changing review to 5 stars.Thank you Powerowl for your help.(Initial Review) Charging batteries for holiday decorations today and the charging lights are flashing. Flashing indicates circuit problem or completely dead battery. I plugged it into various outlets...all with same flashing.Then, I put the same batteries into a different brand charger and the fully charged light went on as it should have after charging was completed. No error signal in alternate brand charger. Hmmmm.Conclusion:This battery charger which I used last holiday and occasionally throughout year is malfunctioning.Very disappointed. The charger is not even a year old.

Purchased this to replace a rechargeable battery charger. It's design is useful that it allows for AA and AAA batteries to charge. While it came with a USB cord for charging, it would've been helpful if it came with a plug attachment as well. Other than that, it charges well and has useful indicator lights to let you know if your batteries are still charging.

This item works as expected. I like that you can charge one battery instead of having to charge them in pairs. The unit does not come with a wall plug, but it does come with a USB charging cord.

I am really pleased it will charge anywhere from 1-8 batteries at a time and it doesn’t matter if AA or AAA or even a combination. Very convenient. It works as described.

I thought it was the batteries or the charger showed it was charged but They kept dying within a few days in the blink doorbell cam and showing not fully charged. Upon much communication with customer service. I've come to realize I was using 1.2v batteries and Blink required 1.5. which made them not show 100% charge in the system and drained them faster according to customer support.Upon googling the Blink system, it also requires non rechargeable batteries.The seller's customer service exchange several correspondence with me and always very promp.

I like that this charger has small LEDs that are red when charging and turn green when the battery is fully charged. Charger comes with a USB-C cable with a USB-A on the other end. Quick and easy to use. Charges AA & AAA.
