Features: Exclusive Isolation Fast Charge Technology: It automatically adjusts current and voltage to achieve maximum power. The 1000MA 5W sunpower solar panel conversion efficiency is as high as 20.5%, while most panels on the market are only 15% or less efficient. Lightweight and portable design: The compact design is easy to carry (size B5 paper), you can hang it on the bag outdoors. Folded into a small package that weighs less than a pound and is very convenient for outdoor activities. Wide compatibility: USB interface: Any 5V USB device such as for iPad mini, tablet, for iPhone, for Samsung, for Blackberry, Bluetooth headset, for iPod digital products. In addition, it also supports 18V output, with battery clips and car cigarette lighter, which is convenient for charging your car battery. Output interface: USB + DC. Specification: Material: PET laminate + Fabric (waterproof): PVC Color: black Monocrystalline solar panel: 5W Output voltage / current: 5V 0-1000MA (dual USB regulated output) Output voltage / current: 18V 0-270MA (chargeable 12V battery) Output interface: USB + DC Packing size: Approx. 190 * 115 * 40 mm/ 7.48 * 4.52 * 1.57 in Folding size: Approx. 170 * 115 * 20 mm/ 6.69 * 4.52 * 0.78 in Expanded size: Approx. 420 * 170 mm/ 16.53 * 6.69 in Package Weight: Approx. 345 g (subject to product actual) Package list: 1 * 5W Solar Folding Charging Panel 1 * Battery Clip Wire (line length is about 3M) 1 * Cigarette Lighter (line length is about 3M) Note: 1. The amount of solar energy converted is changed with the change of sunlight, and it is not always the peak current. 2. Some devices may not be able to charge directly from this panel due to weather conditions or equipment limitations. If you encounter problems, make sure the panel is in bright sunlight and is directed at the sun. 3. It is recommended to use this solar panel with a rechargeable battery to conserve and store the electrical energy generated by the solar panel. Because the solar panels themselves do not store electricity. 1、Exclusive Isolation Fast Charge Technology: It automatically adjusts current and voltage to achieve maximum power.
