JuiceBox: Providing Sustainable Energy to Houseless Communities


The Need in Our Community for JuiceBoxes:

Portland has a large homeless community. A houseless person, unlike a homeless person, is someone who lives in a safe, insulated shelter, but still lacks modern necessities like electricity, electric light, running water, and most importantly a permanent home. Organizations have built communities of small pods to give these citizens permanent shelter and safety. However, these communities lack power. We install JuiceBoxes into these pods to give these people light and energy, which can be used to charge their phones, (which are crucial when searching for employment. Our team has already installed 70 JuiceBoxes, and we plan to install 30 more JuiceBoxes by this spring. JuiceBox provides green, efficient, and sustainable electricity for off-grid shelter pods for houseless individuals. 


Specs of a JuiceBox

  • Each shelter "pod" is equipped with a 100W solar panel that delivers power to the JuiceBox, mounted inside. 

  • The power of the sun is harnessed to charge an 18 AH 12V battery. Batteries are recycled from FIRST Robotics teams.

  • This power can then be used to power devices that plug into a wall outlet  (120V AC, 300W max) or 12V DC automotive accessory socket.

  • The battery also powers a bright LED light bar mounted on the front of the JuiceBox, perfect for illuminating rooms at night, and extending the day of the user.


Where are JuiceBoxes Used?

See the map to the right to find where JuiceBoxes are installed across Portland. 70+ JuiceBoxes are currently installed at Hazelnut Grove, the Kenton Women's Village, Dignity Village, Right 2 Dream Too, and Benson High School, and by this spring we plan to have installed 30 more.


JuiceBox is a winner of the first round of the Lexus Eco Challenge, and is partnered with the Village Coalition and the Rebuilding Center. For more information on JuiceBox, visit www.catlininvents.org/juicebox
