STEP 2: LOAD RECHARGEABLE BATTERIES INTO THE CHARGER 
•  The charger has two independent channels as marked in the battery compartment, 
each of which can take two rechargeable batteries of the same type and size. 
Please ensure batteries are loaded in pairs, either two on the left side or two on the 
right side only. The charger will not work if two batteries are loaded at the centre. 
•  Please DO NOT load unsupported battery types such as Alkaline, Carbon Zinc or 
Lithium batteries into the charger for recharging. Failure to do so may lead to 
battery leakage or explosion. 
•  Please DO NOT mix old, new or different battery types together as this will affect the 
performance of the charger. 
•  Insert 2 or 4 AA/AAA sized NiMH or NiCd rechargeable batteries into the charger. 
•  Pay attention to battery polarities and ensure all batteries are connected correctly to 
the charger. 
STEP 3: OBSERVING THE CHARGER’S STATUS. 
•  Once batteries are firmly in contact with the charger’s metal plates, the charger’s 
indicator lights will be activated straight away, showing the different status as 
follows: 
o  BLUE LIGHT ON – Power is ON and the charger is ready for use. 
o  GREEN LIGHT FLASHING – Battery is being charged. 
o  GREEN LIGHT ON – Charging is finished and battery is ready for use. 
o  GREEN LIGHT OFF – No battery present or improper battery connection. 
o  GREEN LIGHT TURNS OFF AFTER FLASHSING – Battery is faulty, 
exhausted and or is no longer rechargeable.  
USING THE USB PORTABLE POWER FUNCTION 
Apart from the normal useability of a battery charger as mentioned above, the ReZAP USB 
iPower offers far more charging possibilities with its USB port. 
STEP 1: LOAD FRESH BATTERIES INTO THE CHARGER 
•  Load 2 or 4 FRESH, FULLY CHARGED NiMH or NiCd batteries into the charger. In 
emergency cases, NEW ALKALINE batteries may be used in place of rechargeable 
batteries. 
•  Please DO NOT mix old, new or different battery types together as this will affect the 
performance, strength of the USB Output power of the charger. 
•  For best results, please use NiMH batteries of at least 2700mAh in capacity. 
STEP 2: CONNECT AN EXHAUSTED USB DEVICE TO THE CHARGER. 
•  By using the USB cable that comes with your device at time of its purchase or by 
using the OPTIONAL ReZAP USB Multi-charged cable, Model RBC302 and choosing 
the appropriate connector that matches your USB device to connect it to the 
charger’s USB-OUT port. 
•  Slide the USB-OUT switch on the right side of the charger to the ON position and 
start charging the USB device connected. Observe the USB device’s charging 
indication status and the USB-OUT RED LED on the charger for the power conditions 
of the batteries as follows: 
o  RED LIGHT ON – Strong USB output power is charging the connected USB device.  
o  RED LIGHT DIMMING – USB output power is weak and the enclosed batteries need 
recharging. 
o  RED LIGHT OFF – No USB device connected to the charger or the enclosed 
batteries are exhausted and need to be replaced or recharged.
