Quick, what’s the battery health on the laptop or smartphone you’re using to read this? Chances are, it’s not too good—batteries decay, and there’s not much you can do about that.
Well, except for using supercapacitors instead of lithium batteries, like this Blueshift Helium speaker ($400). They charge in five minutes, last six hours, and can be discharged half a million times before you’d need to replace the supercapacitor—so they effectively last forever. Helium comes in mono or stereo, and all of them have that swank bamboo cabinet. Check ‘em out.
