iPhone Portable Solar Power

I’ve been thinking about getting a solar charger for my iPhone for multi day backpacking trips. I just picked up the one below from REI for about $100. There were cheaper ones, but this one had the most power. Out of the box the battery pack brought my iPhone 4S from 60% to 78% in about 10 minutes then was out of juice. I’ll charge it fully with the solar charger then see how it does. In good sunlight it says 6 hours expected full charge. One full charge was supposed to charge my iPhone two times so that’s great. A full charge on a hike lasts me about a day stopping to take pictures once in a while and checking some email if I get a few bars.

…. Lighter and more compact Guide 10 Plus Mobile Kit powerful enough to charge an iPad™

GOAL ZERO, a leading innovator of portable solar power systems, today announced the introduction of the GOAL ZERO Guide 10 Plus rechargeable power pack and the Guide 10 Plus Mobile Kit at Outdoor Retailer Summer Market.

The distinctive new twist of the Guide 10 Plus is that it now also features a 1-Amp output that will give life to an iPad™ for up to five additional hours, while charging cell phones and smart phones twice as fast as the original version.

The GOAL ZERO Guide 10 Plus power pack is designed to work in conjunction with the new Nomad 3.5, a 3.5-watt mono-crystalline solar panel delivered in foldable fabric housing. Weighing in at only 8 oz., the Nomad 3.5 is lighter than many of the electronics that it has the ability to charge, and when folded up, it’s about the size of a small paperback book. The Nomad 3.5 charges a cell phone in two to four hours directly via its USB port and fully charges the Guide 10 Plus in four hours of full sunlight …
