We’re not electrical engineers, so we’re just going to let the people at Blueshift explain why supercapacitors are better than batteries for your portable Bluetooth speaker. “Batteries store energy chemically. Supercapacitors store energy physically, in an electric field. This allows supercapacitors to be charged very quickly, and to be extremely durable–the ones we use are rated for 500,000 recharges.” That’s a whole lot of recharges, but more importantly, it charges in five minutes. That’s right, the good looking, handcrafted in the USA Hydrogen speaker will get you more than 4 hours of playtime with a charge shorter than the line at Starbucks, the time it takes you to put on your socks and shoes or scroll through the most recent updates on your favorite men’s gear site. Sound comes from a 3″ full-range driver built into a ported bamboo cabinet with a Class-D amplifier and outfitted with Bluetooth A2DP and 1/8″ wired inputs. When you factor charging versus playback, Hydrogen might be the best deal in portable audio.
