Battery packs are awesome and an accessory that I always tell people to consider buying when they are on sale. You can keep them in the bottom of a bag, in the glove box of your car, or on your coffee table for those times on the couch where you need extra battery juice but don’t have an outlet near by. You just never know when you might be away from an outlet for an extended period of time with a quickly dying battery that needs to last another couple of hours.
The BookMark Battery is the latest to go on sale in our Deals store. It’s an incredibly thin (4.7mm) 2,500mAh battery pack that will give most phones an entire charge before it needs replenishing. It has a touch indicator to show how much power it has left, comes in either black or white, and was designed to fit perfectly into a pocket, even a pant pocket. It inputs at 5v-1000mA, outputs at 5v-500mA, and has a cycle life of 500 charges.
At $34.99 (regularly $60), this is a solid deal for those who need some backup power.
