All batteries suck, but at least the ones in your mobile devices can be effectively recharged for a while. That’s not true for the AA, AAA, C and D batteries living inside your remote, mouse, keyboard and controller because even the rechargeable options for those batteries suck. Batteriser aims to improve the life of your standard batteries using a thin sleeve built with proprietary technology that allows you to use the extra 80% of energy that most batteries leave behind. Once you attach Batteriser and put the batteries back in your device, you’ll get a battery life extended by up to 800%! In addition to saving you a bunch of money on batteries, it will also reduce battery waste in landfills.
