Ireland’s Sunday Business Post is reporting today that Jumpit, the Norwegian maker of rechargeable batteries for iPods, has announced plans to float on the London stock exchange in a move expected to value it at £25m. The company’s portable docking station — iRecharge — allows users to charge an iPod when a power outlet is not available. “It hopes a flotation on the Alternative Investment Market (AIM) will help it break into the lucrative UK market where iPod sales have been booming,” notes the report. “Jumpit’s devices are mainly sold in the United States at the moment.” The company hopes to float on AIM in June.
