[Hardware-Review] Portable External Battery Backup Charger 1900mAh for Micro USB
It is a great little device but the lack of a cable can make it awkward to use if you have the USB port on the side. But for those whose device has the port either on the top or bottom it’s good news.
As I’ve said it would have been better if it had a 300/400mm cable with it.

I received this product as a review item today and after waiting for it to charge up I can now deliver my verdict.

It connects to my Samsung GSll at the bottom which is fine but, on the HTC One S, the usb port is on the side which makes it awkward to hold as the images show. Plus the charger is upside-down so you can’t see how much charge is left without turning over. I have asked if they could supply me with a micro USB lead which is about 200mm long . This would enable the charger to be kept in a shirt pocket at least, but still very awkward!
The charger kept my SGSll running for two hours and I was only down to two lights on the capacity meter.
Now it would be difficult to say how long it would last on any other device as it depends on what you are running but, I have a moderate amount of apps running and overall, very pleased with the charger.
Summary:
It is a great little device but the lack of a cable can make it awkward to use if you have the USB port on the side. But for those whose device has the port either on the top or bottom it’s good news.
As I’ve said it would have been better if it had a 300/400mm cable with it.
