If you have ever gone on an extended adventure away from your USB wall and car chargers, then you know that your gadgets can quickly become useless dead weights once their batteries run out of juice. Sunjacks solar panel products seek to remedy that problem.
Both the 14-Watt solar panel and the 20-Watt solar panel have dual 5V/2A output USB charging ports. That’s more than enough power to charge two iPhones, two iPads, or one of each (if you have direct, bright sunlight that is). Luckily, SunJack happens to also include one high capacity 8,000mAh lithium- polymer battery with the 14-Watt panel.
The included battery pack has a metal housing and provides two USB charging ports. One USB port has a 2A output suitable for iPads and other large devices. The other USB port has 1A output, which is better suited for iPhones and other small USB rechargeable devices such as a walkie-talkie, handheld GPS, cellular/Wi-Fi hotspot, Bluetooth speaker, GoPro, LED lanterns, LED headlamps, and LED flashlights. Speaking of LED flashlights, each SunJack battery has its very own little built-in LED flashlight. It’s not super bright, but when it’s pitch black in your tent, it works just fine.
If the little LED built into the battery pack isn’t enough light for you, then SunJack has you covered. Their USB CampLight LED Bulb will definitely fulfill your illumination needs. This lightweight bulb contains 8 bright LEDs that puts out a total of 340 lumens with a 270-degree beam angle, which is equivalent to a 40W incandescent bulb. On top of that, the attached USB cable is 7 feet long, more than enough to easily get the light where you want it.
For you power users out there with lots of energy hungry gadgets, the 20-Watt SunJack solar panel is an awesome solution to your off grid charging needs. It comes with two 8,000mAh lithium-polymer battery packs. Talk about power! With the 20-Watt SunJack, you can easily charge two iPads and two iPhones all at the same time!
SunJack claims that these solar panels can put out as much power as their wall charger counterparts, and I have found this statement to be accurate as long as each panel has an unobstructed view of the sun and is properly angled towards it. Of course, since each comes with 1 to 2 battery packs, depending on the model, users don’t really need to worry about having the panel in perfect lighting conditions.
SunJack also claims that the 20-Watt panel is “powerful enough to fully charge an iPhone in 90 minutes and holds enough energy for up to 8 iPhone charges after just 5 hours of sunlight.” I brought along both the 14-Watt and the 20-Watt SunJack solar panels on a two-week camping trip. Not only was I able to charge all my various gadgets over and over again during that time, but I also charged up several friends’ and family members’ smartphones and tablets as well. Based on my experience during that time, I can easily say that SunJacks charging claims are right on the money.
Both the 14 Watt and 20 Watt panels have a built-in mesh zipper pocket where the two USB ports are housed as well as where the battery and cables are stored. There is even a handy elastic band that holds the battery pack securely in place within the mesh pouch. On top of all that, there are little built-in nylon loops, which allow you to attach/hang the panel from things such as a backpack or the outside of a tent. To make things even more convenient, SunJack even includes a couple carabineers with each solar panel as well. If you don’t have something to attach it to, hang it from, or lean it against, then things can get a little frustrating. It would have been nice if there were an included or optional lightweight fold up stand of some kind.
The solar panels and batteries themselves are not water resistant. However, each panel comes with a plastic sleeve that can be used to protect the solar panel, battery pack, and whatever else you are currently charging from a light drizzle of rain.
To sum things up, each of these solar panels and their corresponding battery packs have the capability to sustain the battery of several gadgets for weeks upon weeks as long as there is at least 5 hours of bright sun a day. If you find yourself in the market for an off grid solution to charging your gadgets, then I highly recommend you take a close look at the SunJack 14 and 20 Watt solar panels. You won’t be disappointed.
