Laptop charger uses MIT HF technology to be smallest available

The 65W Dart charger is up to four times smaller and lighter than the charger that shipped with a standard and adds a 2.1A auxiliary USB port. This allows it to charge a laptop plus USB device, such as a smartphone or tablet, simultaneously. 

“The reality is that all modern electronics still come with a clunky AC/DC power converter that is really inconvenient to carry. Dart eliminates the bulk, making it easy to throw in a pocket and have on hand when you need it most,” said Vanessa Green, CEO of FINsix. “With Dart, we aim to lighten the load and provide a sleek, universal charging accessory that fits perfectly into a mobile lifestyle.”

The reduction in size is enabled by patented 300MHz high-frequency power conversion technology first developed at MIT. The launch of Dart follows FINsix’s announcement in January 2016 of a partnership with Lenovo for the 65W Micro Adapter for ThinkPad laptops.

“We’re not really an adapter company; we’re creating the commercially enabled technology to allow VHF power converters to become a significant portion of the market,” said co-founder and MIT researcher Anthony Sagneri. “The idea is to help people reimagine the power delivery in their systems. In places where that’s a bottleneck — which it continues to be, as devices get more dense and capable — it helps the rest of technology progress.”
