USBACH01 charges a pair of USB gadgets at once
USB cables, to charge your iPod along along with your wristwatch (or any other USB-powered devices you may own) directly from any wall outlet without any magic hackery, battery packs, solar cells, or go-betweens. Still, we're not 100 percent sure how many USB ports this thing has (it appears that there's only two), but the convenience of having 'em is probably well worth ¥1,270 ($11) to the traveler ever on the go.
