Keep Your Smartphones Charged With Eco-Friendly Solar Power

Nowadays, few of us can trek off the grid without our smartphones, at least not for more than a day or so until it runs out of power. Granted, there are several solutions, such as, say, a portable battery pack, but if you’re away from a power source too long, the problem becomes keeping it charged. The solution, of course, is a solar powered charger! The Universal Waterproof Solar Charger lets you charge two devices simultaneously or one device multiple times over. And, you guessed it, it recharges by the sun. It’s available right now at a tremendous bargain, reduced from its $49.99 list price to just $13.99. That’s 72% off!

The Universal Waterproof Solar Charger comes with two USB ports and adapters, for both Android and Apple devices that allow you to charge two devices at once. How long the 5,000mAh battery will last—or what it can charge how many times—depends, of course, on what you’re charging. Say, for example, that you want to charge your iPhone 6. To determine the number of times you can charge it (or if you can charge more than one at a time), simply divide the Universal Waterproof Solar Charger’s Milliamp Hours (5000mAh) by the iPhone’s Milliamp Hours (1810mAh), like this:

(5000 Milliamp Hours / 1810 Milliamp Hours = 2.7)

That comes out to 2.7 times. In other words, when the Universal Waterproof Solar Charger is fully charged, you can charge one iPhone 6 almost three times or charge two of them simultaneously one time, with another seven-tenths (give or take) of a charge left over. That same simple formula will work for any device. Granted, some of today’s smartphones and tablets require massive Milliamp Hours, and in those cases, you may be able to charge your mobile device just once, but as long as you can leave the Universal Waterproof Solar Charger sitting in the sun, it will be ready again the next time you need a charge.

Not only is the Universal Waterproof Solar Charger, well, waterproof, it’s also shockproof, meaning that it’s ready for rugged outdoor usage—all for a mere $13.99, or 72% off retail.
