Solar Paper by YOLK
The world's thinnest and lightest solar charger
Charge any devices via USB cable.
Solar paper can charge almost any device that recharges via USB, including, smartphones, tablets, walkie talkies, flashlights, portable game consoles, cameras, video cameras, and rechargeable batteries.
Charge Anywhere Under the Sun
For Solar Paper, we’re manufacturing the latest and most efficient solar panel. Because of this, Solar Paper is the world’s smallest solar charger for the amount of potential wattage it can generate.
Solar Paper can reliably charge your smartphone in about 2.5 hours on a sunny day. That’s about the same as a wall charger.
Easily Expandible Using Magnets.
Solar Paper allows you to expand it in the future if you need to charge larger devices. Our design solution was to create a set of folding solar panels held together using strong magnets. Only need two panels and want to save some weight? No problem. Just bought a tablet and need more wattage to charge it? Also not a problem.
There are a couple of other advantages of using magnets in Solar Paper, too. First, there’s no wear and tear on seams when you fold or unfold the panels, greatly extending Solar Paper’s life. The magnets are also quite strong, so you can use them to mount Solar Paper to metal objects, as shown in the picture
Hanging Solar Paper on a backpack.
Use holes on every corner of solar panel. Connectors for holding solar panels together will be included.
Thin, Lightweight and Durable
Solar Paper measures just 9 x 19 x 1.1 cm when folded, and each panel weighs only 65~75 (2.5 oz). Watt-for-watt, it is 70 percent smaller and lighter than our closest competitor. Most importantly, Solar Paper is just 1.1 cm deep, at its thickest point, compared to 3.8 cm for our competitor, easy to carry it!
The solar panel of Solar Paper are is water resistant. Thus, splashing water shall have no harmful effect. However, an USB part is susceptible to corrosion so make sure to dry it well after exposure to water. If the panels have been exposed to seawater or water with salinity, rinsed the panels with clean water and dry. Water resistant level IP54.
Convenient Auto reset
Unlike other simple devices with a battery, smart devices like smart-phones and tablets would not accept low current caused by insufficient sunlight. In this case, devices have to be manually reset. That means that users have to unplug and replug the cable every time a cloud passes overhead or you walk through a shadow. This is very inconvenient.
We wanted to make Solar Paper as easy as possible for anyone to use, so we have integrated ‘auto-comparison technology’ into the charger, to make it automatically resume powering your devices, after the sun starts soaking it again
Amount of solar power through LCD
For Solar Paper, we’ve included an LCD amp meter that shows exactly how much current is flowing from the charger to your device at any time. It would let you see how the panel performs under different weather conditions.
