The Package
The sealed package comes with a charger, 2 eneloop AA-sized rechargeable batteries, and a dual-use USB battery cable.
The Magical USB Cable
The USB cable has two simple uses - charging and discharging. When you plug in the USB side into the charger, you can charge most phone mobiles with the standard mini USB and USB-ext. Otherwise, you will need the original charging cable.
Conversely, you can plug in the USB side into the computer, and the mini USB side into the "DC IN 5V" slot of the charger, this way the charger will blink in blue, indicating the AA batteries are recharging.
Note: The USB cable is not capable to transfer any data, and is solely for charging/discharging purpose. The cable can, however, be substituted by another USB cable - in fact you must change the cable if you want to charge any device other than those with mini-USB jack.
Feature over other AA battery mobile chargers
There are many other choices around which enables to convert AA-sized battery into mobile device energy, sometimes as cheap as €3, so why did we pick this Energy Booster?
- the mobile devices with higher energy requirement (like iPod, but not iPhone^) can be charged. Read: Sanyo KBC-E1 can't charge iPhone. With two batteries instead of one, the Mobile Booster is capable to add up the mAh of two batteries, so charging a piece of 1500mAh battery is no challenge. Two fully-charged batteries can charge an iPod Touch to around 55%.
- the charger can also be used as a AA-sized Ni-MH battery charger, albeit the speed is very slow. A full recharge of battery requires an overnight charging.
^ iPhone can't be charged by this charger, but can be charged by the internal lithium battery version. You might be interested in Kensington's Power Booster instead.
Stain issue
The white color might look elegant or beautiful, but its shell is very newspaper unfriendly. A slightest touch of newpaper will dye the machine to a disgusting yellowish color. To make thing worse, if you attempt to wipe the stain with a plastic rubber, the charger's surface might scratch.
