Bought one of these a while back. These packs take a long, long time to charge. Use the pack when traveling and find out I generally don't stay that long in any place for it to be fully charged. Yes, I can still use it if it's not fully charged, but there's the nagging thought that I should have gotten it fully charged before I trek off somewhere else. Also, attempted to use this to run a GPS that I couldn't plug into a rental car's cigarette lighter receptacle. The battery pack's output wasn't strong enough to power the GPS, even when the pack was fully charged. Found the LED light function helpful when needed. Carry it around for emergencies for charging spent cellphones.

If you are looking for a portable charger, I'd look at newer models that include card readers and on board wifi.
This for example, http://www.amazon.com/dp/B00CSFCYFY
Granted doesn't have nearly as much juice, but it'll still give you a good 6+/- charges. And with the built in wifi, you can bring along a hefty media collection on a portable HD or SD card and stream instead of having to fill up your devices internal storage.
When what to my wondering eyes should appear, but a bucket of wings and a six pack of beer!
