This device is almost identical to this other
battery extender reviewed previously. There’s exactly the same features –
and on/off switch to allow charging and four "AA" sized batteries are required
to get it working..
The big difference is the power outlet – It’s not a Smartphone
connection, it’s a USB outlet. In theory this means you can plug anything that
is fed from a USB port into this should it require power (I’m not sure whether
anyone would like to try that theory though!) This USB outlet does, however,
mean that a wider variety of Smartphones can be plugged into it to extend
battery life. I tried it with my Tanager Smartphone and everything worked fine –
charging was quick and it’s a life-saver if you’re just about to squeeze the
last bit of power from your Smartphone battery.
On the predictably blurry picture above (I’m not too hot with
cameras!) You can just see the USB outlet – this is exactly the same to the one
on your PC.
