Take advantage of the sun’s power when you’re out on the trails by using a solar battery pack that charges multiple devices at the same time. The Mengo S-Power 5300Mah Solar Powered Battery Charger is for sale on Amazon for $27.89 with free shipping on orders more than $35. That’s 44% off list price.

This back-up battery pack includes an LED emergency light, a carabiner so you can carry it easily and is water and shock resistant. Of note, it only allows for slight water contact, such as splashing and rain. It has dual USB ports so you can charge two devices at the same time like your iPhone, iPod, iPad, Samsung, LG, HTC or Nexus phone.

You can recharge this device quickly by using the USB cable or expose it to direct sunlight if you don’t have access to a power source. It should be noted that it takes a long time to charge this battery using only the sun — a full day charge will only provide the battery with about 1/8 of its total capacity. However, you can just leave it in direct sunlight all the time so it’s ready to go when you need it.
