Handy and effective credit card powerbank with 2500 mAh capacity! As the name suggests, our slimline Credit Card Powerbank is designed to easily slip inside a wallet or purse. Therefore, this device is perfect for on the go charging and will even charge most smartphones to full power. Although it is smaller than the Flat Powerbank, this powerbank is ideal for printing beautiful full-colour photographs! This pre-set design can be personalised with your one text so that you can create a powerbank that is one of a kind! This powerbank has proved incredibly popular since we introduced it, outselling almost everything on the site. We think this is down to the more-than-useful 2500mAh capacity it offers in such a small and slim package.
