If you've been looking for a backup battery for your phone/tablet/bionic limbs, the Lepow Moonstone is on sale right now. I got one on the recommendation of bangishotyou over on the O-Deck and I'm a big fan. It works well, it comes with a lovely felt case, and several DC GT-ers can back me up when I say that it's really pretty.
The 6000 mAh ones is on sale for $15 (usually $60) and the 9000 mAh (in blue only, but the blue seems really lovely) is $20 (usually $80). (Though for reasons unknown, the small green one is $25. ¯\_(ツ)_/¯ ) I have a 6000 and it's been fine for my purposes. ihatepickingnames charged her phone with it on Friday (though IDK how much, since I don't need to know every detail about her life, despite what my constant interruptions in her twitter convos would suggest) and it's still half-full.
I have the black one. It's very shiny and I like it. I don't know if it's necessarily the best battery on the market, but it's probably the prettiest, and having pretty things is nice sometimes. Also, I like to imagine the brand name as a French sound effect, which is fun. Le POW!
