Bad news... only got 2 hours 14 min on a Lenmar PowerPort

Okay, just got my Lenmar PowerPort external battery from UPS.

Pros
can be used with multiple computers
lightweight, less than 1lb
LED indicator to show battery life 0-20%, 20-40%, etc...
charges off of your computer AC adapter, no additional plug required
dual charge port for accessory [I can simultaneously charge my iPhone, headset, iPod, or smaller PowerPort]
Came with a carrying case

Cons
HORRIBLE battery life [2 hours just won't cut it for me]
Two different adapters for each brand [i.e. one for charging the battery and one for charging the laptop, so I have to keep up with 4 different adapters if I want to use this with my u810 and AAO]
again, did I mention the HORRIBLE battery life????

The packaging quoted "4 hours" of charging time for a laptop. I realize this is an approximation, but for me to get almost half the quoted charge when all I had running was IE7 and wifi pisses me off!
