It's normally hard to spruce up a USB power charger, but Osungo gave us a pleasant little treat at its CES booth. It's readying a Flower Power series of wall adapters that are unabashedly cute and, more importantly, can save as much as 95 percent of the energy that's wasted when devices already have a full charge. No, it's not extremely sophisticated, but it doesn't have to be to do some good -- and we'll admit that the pseudo-organic cord wrap is a nice touch. Versions are coming with both 1A of current for phones and 2.1A for tablets, and we're told they should be on sale in March. US-friendly adapters will cost about $25 to $30.
