The Solarpad Kit is designed with a high-quality, custom Suntactics solar panel, which has a fluoropolymer film with the best light transmission, precision cut and tabbed high-efficiency solar cells, and a high-strength substrate. The panel is attached to a housing, which holds the buckle straps and 1/4-20 tripod thread in place. Our Power Core battery uses a high-efficiency, high-power charge controller from Maxim and the housing is sealed, which prevents water from leaking in. Also, Power Core uses the same battery that's used in the Tesla electric car, which is the best battery of its kind. Even the built-in USB cables consist of thicker gage wire, which allows the electricity to flow more efficiently. The Solarpad Kit is engineered to squeeze the most energy possible from the sun's rays in to your smart phone. No short-cuts that compromise power or efficiency are taken, period.

Compatible with Most USB Devices - Charge your phones, cameras, music players, Bluetooth speakers, GPS devices, and more! If it's about the size of a Smart Phone, the Solarpad Kit can charge it. Connect the charge cable that came with your smart phone, or other USB device, and plug it in to Power Core.

Unparalleled performance - A fully charged Power Core will recharge a dead iPhone from 0% to 100% in 3 hours even after being unused or recharged for a month! Other similar sized solar chargers can only charge a Smart Phone from 0% to 70% and take over 4 hours to recharge.

Where Do the Funds Go and How Long Will it Take to Finish?

Solarcycle is here to meet your USB charging needs for the outdoors! We've solved the fundamental problems with solar USB charging, but right now each Solarpad Kit is assembled by me using rapid prototype components. In order to build the final production version at a reasonable cost, funds must be raised to pass UL approval and purchase a minimum order of hundreds of solar panels, batteries, cables, circuits, and plastic components. Other equipment costs include molds for the plastic parts and creating custom assembly fixtures. The Solarpad Kit is designed to be as simple to manufacture as possible and it is always being refined for the most efficient assembly. Our suppliers have given us great quality prototype parts and they are ready to manufacture the components in larger quantities. Typical manufacturing lead-times for components are about 30 days and test batches are always ordered before going in to large-scale production. Tools, fixtures, test equipment, and work benches for assembling products need to be purchased too. Realistically, it should take about 1 year to set-up shop, order parts, manufacture parts, inspect components, assemble each batch, final test each unit, pass UL testing, package, and then ship them.

Risks and challenges

I have a M.S. in Mechanical Engineering with over eight years of experience and a few successful Kickstarter project under my belt. I also gained a lot manufacturing experience working at my Dad's sheet metal shop since I was a kid. Unforeseen issues that can delay the shipment of rewards to Kickstarter backers include, but are not limited to:

* Delays in receiving components on time from vendors.
* Delays from rejected parts during inspection.
* Delays from the carrier in shipping the product to the Kickstarter backer.

As a backer of other projects, I understand the importance of honest communication, even if the news is not so good, so I will make it a priority to answer all backer questions as fast as I can and give updates as soon as possible. We are on this journey together.
