This wireless portable speaker fully recharges in 5 minutes

Unlike the glut of other portable wireless speakers with their gimmicky unique special features — Lights! Antique styled! Beer-proof! — the Helium offers something truly convenient: the ability to recharge in only five minutes when it's out of juice. And that's because it doesn't even rely on batteries like the others. It's powered by a freakin' supercapicitor.

Packed inside its bamboo-briefcase body is an impressively powerful stereo with a four-inch full-range driver, which is capable of blasting at full volume continuously for a whopping six hours without a recharge, and can sustain doing so up for up to half a million charges — far longer than any typical battery-powered gadget would.
