The SunJack 20W Portable Solar Charger 0


Harold Tan, one of the team members at, has launched a new Kickstarter campaign to build and market SunJack, the world’s most portable 20-Watt solar charger and battery pack for off-grid applications and emergency mobile power. The campaign will also benefit the rural villages of Papua New Guinea with smoke-free lighting and energy.

As an off-grid camper and extreme outdoorsman, Tan knows how important charged electronics can be in isolated areas. But whether power was needed for light, weather information, or communication, Tan saw that solar powered chargers on the market today were flawed. They gave too little power too slowly. With today’s power-hungry mobile devices, off-grid campers could wait 12 hours or more to fully recharge and have enough stored energy for map apps, rescue calls, night lighting, or just enjoying music at night.

Realizing the need, Tan designed the SunJack system, a 14 Watt or a 20 Watt fast-charging solar powered battery system that’s lightweight and easily folds into the size of an iPad. When completely opened, the lightweight SunJack systems can be securely attached to a backpack and fully replenish its batteries in approximately 5 hours of direct sunlight.

With the 14 Watt model, SunJack’s 8000 mAh lithium-polymer battery can charge two USB devices simultaneously, run independently from the solar panels, and has a built in LED light for off-grid lighting. With the premium 20-Watt SunJack model, family campers can receive 16000 mAh capacity, enough to power up to 8 iPhones, or 1.4 iPads or 8 hours of 5 Watt lighting.

SunJack is unique for its proprietary USB port and a lithium-polymer battery that was specially designed for faster charging from sunlight. “Think of it as being able to get more water out of your faucet faster,” said Tan. “The SunJack is able to get more electrons flowing into the battery faster than any solar charger available, which means you get wall-outlet charging speeds in an incredibly portable form-factor.”

But SunJack is more than an off-grid power system for boats, beach days, emergencies, and rock climbing trips. It’s also a path for non-toxic lighting for the rural villages of Papua New Guinea. For certain levels of Kickstarter investors, Tan will donate a SunJack and an LED light to a rural village, enabling rural families to learn to read and perform indoor chores at night without breathing noxious kindling wood fumes.

The SunJack Kickstarter campaign is running from now until Thursday, May 15th and will offer backers several early investor values, including portable solar lights and significant discounts off SunJack’s projected $250 retail price. If the Kickstarter campaign is successful, backers should receive the first production SunJack at the end of June 2014.
