Mediarange 191 fast charger
Mediarange 191 rechargeable battery charger
Light, handy stil powerful
The Mediarange 191 battery charger is a cheap charger, yet it has 4-channel charging technology. In addition, it is fast and suitable for either 1 to 4 AA or 1 to 4 AAA rechargeable batteries.
In addition to its cheap price & charging power, this charger has another very big plus point, namely the 4 separate battery charging controls.
Four channel charger
The charger is suitable for four AA or AAA rechargeable batteries. Each battery is charged separately (4 channel charger).

What is 4 channel technology?
In this case, the four represents the four slots that the charger has that charge independently of each other. If the charger had eight slots that charge independently of each other, it would be an eight-channel charger.
By charging the batteries individually, each battery is optimally charged and you are flexible in use. It no longer matters whether you want to charge different capacities together or whether a battery is not yet completely empty. Most battery chargers charge per set of 2 batteries, if they do not have the same capacity or if 1 is not completely empty, something goes wrong. This charger has 4 separate charging channels, each channel is monitored by a microprocessor that ensures an optimally charged battery.
Example 1: a 2-channel charger
Battery 1 is an AA 2700 mah and number 2 is an AAA 1100 mah. Both batteries will now be charged at a maximum of 1100 mAh because the charger stops when battery 2 is full. The result is that battery 1 is not even half charged and is quickly empty!
Example 2:
Both batteries are AA 2700 mah, but battery 2 is half empty. Again, both batteries will be charged with a maximum of 1350 mah because the charger stops when the half-full battery is full, which is after 1350 mah.
If you use batteries of the same capacity and in one and the same device, you will not notice this, as the batteries are just as empty and are therefore just as fully charged.
