If you're looking for quality backup power packs and chargers you can't go wrong with Anker. Their Optimus Prime is a licensed edition of their Prime power pack and is a two-in-one charging block and portable battery. Unlike many other licensed products with Anker, you're paying for quality, not the license. If you're looking for an on-the-go power source while representing Transformers, this Anker charger is perfect for you.
