Texas Instruments started the week by promising a very small wireless power chip, the bq51013, that could lead to the technology spreading to other devices. Its design measures just 0.12 inches at its longest point, 80 percent less than TI's previous version, but can still provide the 5W of inductive power needed for smartphones, MP3 players, and most other mobile devices. It backs the official Qi power standard and should work with any charger that supports the standard.
