Rugged external battery review topic

Awhile back in one of my external battery review threads we had a discussion about using these batteries outdoors, which makes sense since you will be away from power outlets. Recently I came across and just reviewed new New Trent PowerPak rugged external battery (14,000 mAh) which I posted about in General Accessories section of XDA forum: http://forum.xda-developers.com/show....php?t=2621202

Since I know not everyone visits that section of the forum, I want to drop a line here in case if someone is interested or want to discuss it further.
