I am really impressed at how New Trent was able to fit a 5200mAh battery into such a small design.  I also like the fact that it has a charging/de-charging indicator and has the bonus of having a laser pointer and LED flashlight.  This would be the perfect battery to keep in a laptop bag for meetings or presentations.  I also like the fact that it is charged by a micro USB cable and doesn't require any special adapters.  I would rate it a 5/5.
