I normally use something called a Power Monkey from Power Traveler as a portable charger. I've misplaced it, so I bought this thing called an Energy Bar from Mobile Solutions in the mall. I think I'm using it correctly, but it didn't come with any instructions. I've looked online & also typed in everything that was written on the box. I found the company, which is Chinese, but did not see what I bought in their list of products. Does the light turn green on the end of the bar when it's fully charged & how much charging will I get out of it, using it on an iPhone 5? I'd greatly appreciate any help.
