This is the perfect size portable charger! There is an adapter for charging tablets. It looks like a little usb extension but somehow charges the tablet. I have used this to charge an asus tf700, samsung galaxy note 10.1, and the nexus phone. Charges fast and is very portable. There is also a nice little carry case that comes with this as well. I'm not sure why there is a laser pointer and led light on this, but it sure doesn't take anything away from the product. The laser is nice and it is a good thing to have just i case you need it. Definitely worth the money!!
