Thermoelectric devices have become efficient enough—and battery technology has improved enough—to finally allow electronics to replace the ice pack.
That’s what Alex Aguiar, a founder of RecoverX, told me. He says the company’s portable hot/cold wrap is deisgned for general athletic recovery. But, he says, they are also good enough to replace the post-surgical ice machine. If you’ve never had one in your house, trust me, this would be a really good thing: those machines are expensive, unwieldly, and you go through a ridiculous number of bags of ice, some of which you will accidentally dump on your living room rug.
