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

PowerOwl products are my new go to for all my battery product needs. Originally, I was attracted to the style and design of the batteries and I really enjoy the brand name PowerOwl. After receiving this product, I was very impressed with the charging technology which allows me to know when the batteries are charged and ready to go. I am super happy with their dedication to bettering the environment by making excellent rechargable batteries available. I also reached out to their support team to ask questions regarding the registration of my products and ensure my batteries and equipment are protected with the offered warranty. I was not expecting such a quick response, but one was received within fifteen minutes by Mattina whose professional, friendly and approachable demeanor made it simple to find the answers I was looking for. They really are an excellent company with excellent representatives. Thank you so much for helping me with my battery needs an I look forward to a long term relationship with PowerOwl!

This product is a great money saver! It charges quickly and is simple and easy to use! I use lots of triple a batteries and I’m saving a lot of money using this to recharge batteries instead of buying new.

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.

Very good battery charging system with east to see indicator lights. Can charge 8 batteries at a time.i would buy again.

Easy use and set up. Lights show the progress. Really good charger. Came a like cracked but no biggie. Simply fragile case and I was not careful. Not sureIf it's slow or fast charging but it gets there.

Battery grip for my Nikon D750 Arrived today. Bought this charger & batteries for photography. Have not yet used it taking pictures. Did a functions test. The grip fits right and tightens properly. I decided to test rechargeable batteries. The battery charger charged the batteries quickly and powers the camera well enough for my test. I will try to give an update on the performance in a few days. I will say that a wall adapter is needed to charge the batteries properly and quickly. Using a USB port in an outlet was too slow and may take hours to charge. I recommend using quality batteries such as Energizer, Duracell, Eneloop.

Charger works great on rechargeable solar batteries. Great tool particularly when the weather is cloudy
