Jastek Universal Travel Charger Kit
I ordered this charging variety pack after being asked if I had a charger by my coworkers all the time, and it has worked wonderfully! There is literally a plug on this thing for every cell phone we have at work, and you can charge more than one at a time, it just takes it a little longer. The cords are somewhat thin, which makes me wonder as to how long they will hold up.
And it connects via a USB port so you can use a wall charger, or a computer, or anything that has a USB port to charge with. I have it centrally located in the office and it is very convenient! Overall it is worth the money paid.
