  • What's Included
  • EnerPlex's Surfr SFG-2500-BK Solar Panel Charging Case for Galaxy S4 utilizes your Galaxy S4's standard battery in addition to the case's separate internal battery that is charged and powered by free solar energy, or USB connection, to give you the peace-of-mind that your phone can be charged and used when the power runs out. The solar energy gathering case has a built-in 2,500 mAh battery that doubles the battery life of your Galaxy S4, and trickle charges your Galaxy S4 via the flexible thin-film solar panel on the back for increased music playing capacity, web surfing time, and talk time. The casing protects your Galaxy S4 from minimal bumps and jolts with an added hinged-door for improved screen protection while also being unobtrusive enough to maintain the Galaxy S4's sleek look, and provides you access to important access doors to the camera, phone jack, and charging port.

    Additional features of the solar casing are the micro USB input for data transfer and simultaneous charging of the solar case and phone, and LED solar charging and battery indicators. The solar panel casing is not designed or meant to replace your actual Galaxy S4 battery, but rather used to power your phone in emergency or non-emergency situations when you don't have power. The solar charging process is slow (an hour of direct sunlight gives you about 10 minutes to 15 minutes of talk time) but effective and useful whenever you need it.

    Review of 64318BK

    Works as expected. I have used it on a SAR mission already. USB cord is a bit short, but it does charge! Its good to have backup power w/o having to go get another battery pack (I have one from PowerGen)
