Keystone’s New Portable Solar Battery Charger Charges Electronics by Tapping into the Sun, the Earth’s Ultimate Sustainable Energy Source

Keystone ECO Solar & USB Power PAK doubles talk time for iPhones, iPods, smartphones and hand-held games

(PRWEB) June 29, 2011

Summer days, heat waves and sunrays means one thing. It’s time to step out and soak up some long-awaited summer fun. Hoards of people grab their smartphones, iPhones, iPods, maybe a GPS or other small electronic devices as they head out into the sun. But after a day of heavy use, those devices will experience battery drain. Keystone’s portable solar battery charger ECO Solar & USB Power PAK comes to the rescue.

Keystone ECO™ Solar/USB Power PAK is a portable solar battery charger that lets users harness the sun to save up back up power. The ultra light-weight Power PAK is equipped with a high efficiency mono-crystalline solar panel that collects energy in direct sun and partial sun. Aside from charging via the solar panel, its built-in 1500 mAh Lithium-Polymer battery can be recharged simply by extending the built-in USB key and connecting it to the computer.

The Power PAK is fully charged after 5-6 hours in full sun or in 3-4 hours through the USB connection to a computer. The fully charged Power Pak offers twice the talk time for smartphones, three times the music time for iPods and Mp3 players and three times the video game usage time.

The Power PAK includes five connector tips to fit micro USB, mini USB, PSP, Nintendo DSi as well as a charging cable specific for iPod and iPhone. Users simply select the connector for the device, plug one end into the Power PAK and the other end into the device. When the device is fully charged, the Power PAK will automatically switch off to protect it from overcharging.

The pocket-sized Power Pak comes with an easy-carry strap so users can attach it to a backpack, beach bag, golf bag or just about anywhere it can catch some rays while they are on-the-go. A charging level indicator lights up, indicating the Power PAK is charging and will turn off when complete.

Keystone ECO Power PAK comes with a complete package for people on the go, including a carrying pouch, easy-charge hanging strap, a charging cable for iPod and iPhone as well as five connectors for most small electronic devices.
