Hands-on the Vinsic 14W Dual-USB Solar Panel Charger

Measuring nearly 33-inches in length when completely unfolded, this solar charger packs 4 durable plastic solar panels that have been sewn into its polyester canvas. There are 4 metal rings on both ends that you can use for securing to your backpack, kayak, or anything else you might be utilizing outdoors. It's even lightweight, weighing only 1.5lbs. Inside the first fold you'll find 2 USB outputs with an LED light in-between. You can keep your mobile devices inside this same pouch, providing a 7.75 x 4.5-inch storage space that shields them from direct sunlight.

As with any solar charger, a sunny day is optimal for the quickest charge, which is 2.1A for this particular unit. If it's a little cloudy outside, it will still get the job done — albeit a bit slower. With 2 devices connected, the fastest rate you can expect is approximately 1A per device. Included with the solar charger is a single 28-inch microUSB cable, so you'll need to pack an extra if you're planning to charge a second device. The 14W monocrystalline solar array is pretty efficient for general use, and manages to juice-up a single device as quick as a traditional charger from my experience. I actually left mine out during a brief sun shower, and my Lumia 640 XL stayed dry inside. It's not completely water-resistant, but it can certainly handle a little rain.

Our take

The Vinsic 14W Dual-USB Solar Panel Charger isn't the most efficient way to charge up your devices, but it's definitely great to have on hand in case of an emergency. Its foldable design makes it compact enough to toss in your bag and carry with you during long hikes. Stay prepared and nab it from Amazon for $47.90.
