Power banks are quite a 'must have' now. The more we rely on our gadgets, the more we need to make sure they can last through the day.
So, as a promotional item, the power bank has got to be one of the most useful products out there.
There are lots of different types but our favourite ones are metal finished with enough mAh battery power to fully charge a smart phone from scratch. They are tactile and generally come shaped round or square.
Of course, if you want to charge a tablet then something like 7000 mAh is required and these lovely flat promotional power banks ones are just the business. A nice, shiny finish, easy to slip into a pocket or bag and a lovely big print area for your logo and message. They have two usb ports for use with more than one gadget.
