TOKYO--(BUSINESS WIRE)--Jul 26, 2018--Rebglo Limited (“Rebglo”) today announced availability on its online shop for the Hettarer “red patch,” an adhesive patch of conductive paper that improves the battery performance of smartphones and other mobile devices by 20-40% for up to 60 days.

The red patch is the brainchild of Tokyo-based entrepreneur Makoto Murakoshi, who wondered if charged particles from electric currents flowing naturally in the air, plus those discharged by mobile devices, could be harnessed to slow the rate of dissipation of a battery charge. He then called in some tech-savvy friends and soon had a working product ready.
