Question 1

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.

Accepted Answer

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.

Question 2

Can this charger charge duracell and energizer rechargeable batteries or does it only charge powerall rechargeable batteries?

Accepted Answer

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.

Question 3

This charger input 220v?

Accepted Answer

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

Question 4

What does the flashing yellow light mean, or the dull green light?

Accepted Answer

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.
