You don’t have to say it. Nobody says it, because everyone is experiencing it. Your smartphone and tablet batteries charge far too slowly. Part of the reason for that is the power lost in those annoyingly bulky power converters we get. Transphorm, a startup which has been around for about six years, could be changing all that soon.

Their aim is simple: convert power without energy loss. Power grids offer alternating currents, while our devices need a direct current. In converting the energy, we stand to lose up to 50% of our juice. The technology behind what Transphorm is doing is as simple as it is sublime, but hasn’t yet seen the light of day because of manufacturing woes.

Transphorm’s power converting tech uses gallium nitride, which we find in LEDs. An expensive process, the company says they’ve come across a way to produce it at a fraction of the traditional cost. This new thinking also gets us away from the silicon parts used in most chargers, like the one your cell phone or computer is plugged into now. In addition to quicker charges, it could end up saving lots of terawatt hours — and money.

A few weeks ago, Transphorm quietly announced they’d taken a big step in solving the manufacturing issues by purchasing a unit of Fujitsu. The Japanese company had technology that rivaled Transphorm, and rather than race to the start line, they decided to come to an amicable solution. In the deal, Fujitsu became a shareholder in the company, and will handle the manufacturing process while Transphorm tries to get the word out about their technology.
