About this project
What is Dart?
The Dart is the world’s smallest, lightest laptop adapter. At a powerful 65W it is a perfect complement to today’s thin, lightweight, portable laptops. It fits in a pocket and is designed with a USB port and single outlet profile to make it easy for you to stay charged up when you're on the road. We hope you are as excited about the Dart as we are and looking forward to finally carrying just one, tiny Dart to charge all your electronics. Join our campaign and never be stuck powerless again!
New 4/30 – Announcing $500K Dart Stretch Goal
If the Dart campaign reaches $500,000 every Dart will ship with a detachable cable! We believe a detachable cable makes the Dart a better product and will create additional flexibility and value for ALL our backers. It will simplify cable management, reduce the risk of damage at the cable attach point, and enable us to offer shorter, longer, or multi-USB cable options in the future. More details are available in Backer Update #5. You can help us hit our stretch goal by sharing our Kickstarter page and/or by further supporting us at www.finsix.com where Dart bundles (sets of Darts) are exclusively available.

Dart is designed to work with all major laptop brands and a majority of today’s laptops. To ensure your laptop will work with the Dart you can use one of two methods:
- The Dart works with laptops that have a voltage of 18 - 21V* AND a power level of ≤65 watts. You can check the rating of your laptop and/or laptop adapter in the small label printed on the bottom of the unit. If the power level is not provided, multiply the voltage (V) by the current (Amps) and make sure this number is ≤65 (W). Note: Make sure to use the INPUT voltage/current on the laptop label and/or the OUTPUT voltage/current on the adapter label.
- Confirm that your laptop is on the Dart Laptop Compatibility Guide. If you do not see your laptop listed here, you will likely see it listed on the Laptop Non-Compatibility Guide. If you do not see your laptop listed on either Guide, please contact us at email@example.com.
*MacBook users: Please select the Dart for MacBook. The standard Dart is NOT MacBook compatible. The Dart works with all MacBooks 65W and under. There are a few MacBooks that require >65W for regular charge speeds; these laptops - namely the 15" and 17" MacBook Pro and the 15" MacBook Pro with retina display - are not compatible. Also, we have added a design provision to the Dart for MacBook that enables it to connect to both MacBooks (using the Apple connector) and PC laptops (using the standard set of PC connectors). If you have already purchased an additional Dart because you weren't aware that the Dart for MacBook had this dual capability, feel free to cancel your second order.
The Dart’s Secret Sauce
The Dart's radical reduction in size is enabled by patented MIT technology called very high frequency (VHF) power conversion.
Simply put, an AC/DC power converter (the power brick) takes the power from your wall and regulates it to the right voltage or current for your electronics. Today, AC/DC power converters are everywhere. All of your electronics from your laptop, tablet, and phone to your LED lights, gaming consoles, and TVs require a relatively bulky AC/DC power converter. FInsix's patented VHF platform makes these converters radically smaller.
It is well known in power electronics that increasing switching frequency is key to reducing size, weight, and cost. However, it is critical (and very hard) to switch faster while maintaining high efficiency. This is because modern power converters repeatedly deliver small packets of energy to the electronic device in cycles called switching cycles. Switching isn’t a perfect process and during every cycle some energy is wasted in the form of heat. At FINsix, our technology allows us to waste far less energy with each cycle. Thus, we can cycle up to 1000x faster without wasting any more energy than a conventional power converter. Cycling faster means we can transfer a smaller packet of energy to each cycle - and make the power converter a lot smaller.
The FINsix Story
FINsix was founded by a team of MIT graduate students with the goal of using our technology to radically shrink the bulky chargers for all your electronics. We chose the laptop adapter as our first product and set about the task of taking VHF power to commercial production. To help us achieve this objective, we've built a dedicated team that includes several veterans of the power industry specialized in product design, system integration, and manufacturing. The team is now 18 strong and based in Menlo Park, CA. Learn more about our story and our focus on adapters here.

Chris Strickler, Senior Principal Engineer: Formerly Director of Engineering at Comarco, a company that designs and sells small form factor laptop power adapters.
Product Development & Manufacturing
The Dart's design is set and we are now moving into approvals and pre-production. This means we expect to see only minor changes before product release. Our next phase will be focused on testing for design validation, completing the required certifications, and spinning up our production lines. A timeline detailed is provided below.
We are fortunate that all the pieces of our system are standard “off-the-shelf” components. These include conventional PCBs, transistors, and passive elements such as capacitors and inductors. As a result, despite the breakthrough nature of Dart's design, it is relatively straightforward to manufacture. We will provide regular backer updates as we finalize our supply chain, complete approvals, and get ready to ship your Dart.

Risks and challenges
Regulatory Approvals: We are confident that we have a robust, reliable and safe product; however, the approvals process can be unpredictable and add time to a schedule. We have mitigated this risk by designing for certification and by hiring a veteran team with decades of experience navigating this process with laptop adapter products.
Supply Chain: There are also inherent risks around establishing robust and repeatable manufacturing processes. We are projecting four months to set-up production because we know the Dart will use standard manufacturing processes as well as off-the-shelf electrical components. That means that every component in our system can be sourced reliably in volume today. However, manufacturing issues can easily delay delivery, so the supply chain effort will be a top priority for us in the months to come.
Fulfillment: We expect to fulfill the majority of our rewards directly from our contract manufacturing partner. We expect to finalize our third party logistics partner in September. For rewards that are custom-painted we will be fulfilling limited orders from our office in Menlo Park, CA.
We will be keeping all our backers fully informed as we finalize our manufacturing partner(s), receive regulatory approvals, and start production.Learn about accountability on Kickstarter
