Battery banks now a days are a dime a dozen. Major manufacturers have a variety to choose from, but are often a bit pricey. 3rd party manufacturers like Limefuel and Anker make solid products that continuously impress with their designs and mAh vs price. While I wouldn’t personally ever leave the house for an over night trip without at least one battery bank charged up and in my bag, there are times where I wouldn’t mind a fair amount of power in a smaller package. The BookMark by Vorson certainly looks like a contender on the portability side of things.
They don’t call it the BookMark for no reason. Looking at the images you can see just how thin it is. Actual measurements state it is 4.7mm. To put that into perspective, the Samsung Galaxy S5 lists it physical thickness at 8.1mm. The outer casing of the battery bank is flame-resistant and shockproof.
Vorson has the BookMark battery Bank listed for $59.99 on their company website, but you can get one right now through StackSocial for the discounted price of $34.99 and can choose between black or white.
