Being without power is being unprepared. Whether you’re on a multi-day hunting trip, traveling abroad, or making sure you’re ready in an emergency, the ability to charge a phone, light, laptop, riflescope, GPS, speaker or an array of battery-powered technology wherever and whenever is crucial to comfort and survival.
Luckily, when it comes to portable solar chargers, the decision is cut and dry, with Sunjack’s all-inclusive kits outshining the competition when it comes to speed, capacity, durability, and price.
As a baseline, all of Sunjacks 5, 15, and 25-watt kits pump out 2 Amps of power per USB port — twice the speed of normal cables — providing wall outlet charging speeds. Sunjack’s solar panels have a smart IC chip that identifies the device it is connected to maximizing charging speed while protecting it against damage from overcharging — meaning you’re able to plug any USB or USB-C powered technology straight into the panels to get energy right from the sun.
Unlike other portable chargers that are made with PET, all of Sunjack’s panels are made with ETFE, a fluorine-based plastic that allows for 15% more UV permeability than its counterpart and is both more flexible and durable against chemical corrosion.
Sunjack’s 15-watt and 25-watt kits come equipped with lithium-powered batteries that can be recharged off the solar panels, providing enough backup power when the sun isn’t shining to charge a smartphone 80% faster than standard chargers up to five times per battery. Both fold down to the size of a laptop or small game board, with the smaller system weighing in at 2 lbs and the larger one at 2.7 lbs.
For those concerned with pack weight on long-distance outings, Sunjack also has a compact 5-watt system with a battery charger, solar panel, and emergency flashlight all built into a single unit and weighing only 1.15 lbs.
One reason for Sunjack’s competition smashing stats is that solar charging is in the company’s blood. Sunjack’s parent company GigaWatt owns the number one DIY home solar company in the United States, giving Sunjack a leg up in experience and technology that other portable solar power companies don’t have.
The reliability, compatibility, weight, and power output of Sunjack’s portable solar kits make them ideal to store in home and vehicle survival kits or take on multi day outdoor excursions. Each lithium-powered battery in the kit can hold a charge for 3-6 months and can recharge on the go by either wall outlets or the sun.
Adventures and emergencies don’t wait. You’re either ready or you’re not. With a portable solar kit like Sunjack in your arsenal, you can count on being ready.
