USB Powered Beverage Cooler Bag

We’ve seen USB powered drink coolers before and usually they are either a mini-mini-fridge the size of can of soda or look like a plate that cools your drink from below. This beverage cooler is a little insulated bag, a USB powered drink cozy if you will. Seems like a pretty decent idea- I’m not sure how effective it would actually be, especially since this is from one those cheap gadget makers from Asia, and I would think that their claim of it decreasing in temperature “to -10 degrees after 5 mins” is just a translation error and that it drops the temperature BY -10 degrees after 5 mins (but even that seems a little dubious to me). Either way it’s around $9.
