## Description

desertcart.com: POWEROWL 8 Bay AA AAA Battery Charger, USB High-Speed Charging, Independent Slot, for Ni-MH Rechargeable Batteries, No Adapter : Electronics

Review: 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.
Review: Great product - Working great !

## Questions & Answers

**Q: What does it mean that you shouldn’t charge pairs? Does it mean don’t charge just 2 at once?  I thought you could charge any number of batteries.**
A: I'll try to back up DevlinPaddock here, as some folks still seem confused.
Simply put, the good people at Powerbowl are explaining that some 'other' manufacturers attempt to make a bit more profit by using fewer parts/charging paths in 'their' chargers. However, this forces compromises on the user (you). Instead of 8 -independent- charging slots, the other guys provide 4 Pairs* of slots. These 'paired' slots MUST be used in pairs - they won't work with only 1 battery in them. And, as mentioned before, if the Pair of batteries are not IDENTICAL in both capacity & charge level (when you put them in) one of the two can be Overcharged (which is bad.)
The Powerbowl Charger eliminates these issues entirely. It's got 8 Independent charging slots, meaning that you can charge 1-8 batteries at a time AND you can mix & match sizes - in any order you see fit.

Powerbowl really has your back here. This charger saves you money in the long run, but also saves your batteries themselves WHILE giving you charging flexibility at the same time.

     * or in some cases (for the really chea, err, 'inexpensive' brands) 2 sets of 4.
     How often are you going to have 4 identical batteries - at the same level of 'drainage' - that need charging - at the same time?
     It's just, well, wrong to put those kinds of limitations on a customer; just to make a few percent more profit.

P.S. I don't work for them, I just appreciate it when a company not only makes a Fine Product, but also doesn't pinch every penny possible at My expense.

**Q: Can this charger charge duracell and energizer rechargeable batteries or does it only charge powerall rechargeable batteries?**
A: Yes. It worked for my other batteries. I had rayovac, energizer, and Duracell batteries. Some of them were defective so it didn’t charge all of them. But if they are good. The charger does work for other batteries.

**Q: This charger input 220v?**
A: It doesn't run directly off 120 or 220. It runs off the 5 Volts from the USB output of a laptop or USB power adapter. So if your adapter is 220, it will be fine. So whether your adapter is 120 0r 220 both will be putting out only 5 volts through the USB output

**Q: What does the flashing yellow light mean, or the dull green light?**
A: Hello. I am looking at the instructions. First of all use only rechargable  batteries. There is NO yellow lights. The indicator lights are  Red means batteries are charging. When indicator lights turn green batteries are charged. When batteries are defective, wore out, or inserter in charger the wrong way, the indicator blinks red. Hope this helps.
