- Can charge most smartphones in 90 minutes under direct sunlight
- ETFE coating allows up to 19 percent efficiency in light absorption
A lot of people have been craving outdoor activities, be it camping or hiking, ever since the pandemic started. Even in general, people seem to be attracted to grounding experiences in nature to rejuvenate their energy levels after spending a good amount of time living busy lives.
At the same time, though, nature can be unpredictable. As such, it would be vital to carry medical kits and essentials including digital gadgets for assistance in case you need them while you’re out.
Sunjack’s 25 Watt foldable solar chargers come with 10,000mAh power banks that can store enough energy to charge eight standard smartphones after just five hours of direct sunlight. With two in-built USB ports that can pump out two amps of power each, you can charge a smartphone in just 90 minutes.
The monocrystalline solar cells absorb solar energy with an efficiency of up to 19 percent and offer better longevity and heat tolerance compared to polycrystalline solar cells. The ETFE (Ethylene-Tetra-Fluoro-Ethylene) coating on SunJack’s solar panels makes them durable, corrosion-resistant, shock-proof, and water-resistant.
Compared to PET (Polyethylene terephthalate) coating, the ETFE coating on these solar panels offers longevity for up to 10 years without compromising on performance. Another important aspect of ETFE coating is that it offers ultraviolet permeability of up to 95 percent. This facilitates optimum light transmissibility leading to higher solar energy absorption.
You may plug in your personal power banks to store electric charge but those that come with Sunjack’s solar panels are optimized with the whole setup capable of discharging up to three amps of power. The 10,000 mAh power banks come with Qualcomm 3.0 Quick Charge capability and are also compatible with QC 2.0 gadgets.
Furthermore, a smart IC chip in the solar panels protects the device from overcharging or overheating. All foldable solar panel chargers from SunJack come with a 1-year free warranty. When you place an order, SunJack strives to FedEx the product within the day of purchase for free.
