The charger itself is a nice and small little unit that is powered by a USB cable, it simply plugs in to either a PC, laptop, playstation, Xbox, or USB power supply that provides DC 5-9V and 1.5A or more. The idea is that you can use Rechargeable AAA batteries rather than disposable ones and this should mean you spend less money in the long run.

 Step 1. Connect the supplied micro USB cable to the input port

 Step 2. Connect the USB side to your chosen power supply.

 Step 3. Make sure if you are charging from a PC, or games console that they are powered on.

 Step 4. Insert your batteries but make sure you double check the polarity!

 Step 5. When the charging starts the blue LED lights will blink. 

1 blink = very low

2 blink = low

3 blink = not long now

Solid green = battery charged 

 Step 6. When the green light on the individual channel is solid, remove that battery and put it to one side. 

Red blinking light means that you have an issue so check below to see what it could be! 

 

Single red blink = internal resistance is too high or you are trying to charge a none rechargeable battery... ( DO NOT DO THIS ) 

 

Double red blink = charging temperature is too high or low

 

Triple red blink = charge capacity or charge time has been exceeded 

 

Solid red = hardware error, disconnect and speak to your local model shop. 

 

These really are plug and play chargers and as long as you put the AAA cells in the correct way there is not much you can do wrong with these.
