Solar Pack With A Punch By Sunjack
Don’t miss this thorough review, and endorsement, of the Sunjack by bushcraftbartons. Barton puts his Sunjack to use as part of his work in the outdoors up North. It is rugged, and powerful enough to fully charge most phones in 90 minutes and holds enough energy for up to 8 smartphones after just 5 hours of sunlight. The Sunjack can be spread on the ground or even carried on a backpack. Do you have a solar charger as part of your survival kit?
