Use the sun's energy to generate free electricity and remain self-sufficient. It doesn't matter if you are traveling by plane, camping, or hiking to the nearest lake. Wherever an outlet is not available, this useful compact solar panel will help you with your power supply.\u003cbr\u003e\u003cb\u003e\u003cbr\u003eSimply open it, place it, and start producing green solar energy immediately\u003c\/b\u003e\u003cbr\u003eIt is very easy to use. Open the solar panel and align it as perpendicularly as possible to the sun. You can connect the devices to be charged via a suitable USB cable (USB cable not included in the package) or via the included DC connection cable, and charging will begin without further delay.\u003cbr\u003e\u003cb\u003e\u003cbr\u003eUniversal charger with flexible connection options\u003c\/b\u003e\u003cbr\u003eAlmost all devices with a USB power connection can be charged without any problem. This is because it has a USB A connection socket. There is also an additional universal connection socket for DC barrel plugs with a diameter of 5.5\/2.1 mm. The delivery package includes a universal connection cable with a 5.5\/2.1 mm DC barrel plug on both sides and a length of 2 meters, as well as 3 plug adapters (3.5\/1.35 mm, 5.5\/2.5 mm, 8.0\/5.5\/0.8 mm). The polarity of the connectors is as follows: Inner contact = positive (+), outer contact = negative (-).\u003cbr\u003e\u003cb\u003e\u003cbr\u003eDevices that can be charged\u003c\/b\u003e\u003cbr\u003e\u003cdiv\u003eAll devices with a USB power connection or the aforementioned DC plug connection, such as smartphones, tablets, power banks, portable PlayStations, MP4 players, GPS devices, and Bluetooth headphones. For charging large power stations, we recommend more powerful solar panels with an output power of at least 60 watts - see item nos. 3810050, 3810060, 3810070.\u003c\/div\u003e\u003cbr\u003e\u003cdiv\u003e\n\u003cb\u003eHow long does it take to charge a battery?\u003c\/b\u003e\u003cbr\u003eMost modern devices with built-in batteries indicate the current battery charge status on a display or via status LEDs. The charging process is also automatically interrupted by the internal charger of the smartphone or tablet, etc., as soon as the battery is full.\u003cbr\u003e\u003cbr\u003eHowever, it is useful to know how long a full charge theoretically takes with an empty battery. This is important, for example, for selecting the appropriate solar panel for the requirements of the devices you want to charge.\u003cbr\u003e\u003cbr\u003eHere is a small example calculation. Divide the battery capacity (mAh) by the charger's charging current (mA) and multiply it by a factor of 75. This gives you the approximate charging time in minutes required to fully charge the battery to 100% of the sun's duration.\u003cbr\u003e\u003cb\u003eExample:\u003c\/b\u003e A battery with a capacity of 3000mAh (3.0 Ah) and a charging current via the 5-volt USB connection of 2400mA (2.4 amps). SO 3000: 2400 x 75 = 94 minutes. Dividing the result by 60 gives the charging time in hours: 1.6 hours.\u003cbr\u003e\u003cb\u003eThis means that an average smartphone can be fully charged in just 1.6 hours with a 21-watt solar panel.\u003c\/b\u003e\u003cbr\u003e\n\u003c\/div\u003e\u003cbr\u003e\u003cb\u003eCarabiner hooks included for mounting\u003c\/b\u003e\u003cbr\u003eTo ensure that the solar panel can be securely mounted to an object and aligned with the sun, 2 robust carabiners are included in the delivery package. These can be attached to the riveted eyelets of the solar panel, allowing for stable attachment, for example, to a tent loop, a fence, or other suitable attachment points. It can also be directly mounted on a backpack for charging during a hike.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eInnovative solar cell technology with high efficiency\u003c\/b\u003e\u003cbr\u003eMonocrystalline silicon cells ensure high efficiency and the fastest possible charging of device batteries. This means maximum electricity output per solar surface. Despite their compact design, relatively high charging currents and short charging times are possible.\u003cbr\u003e\u003cbr\u003eEasy transport\u003cbr\u003eThanks to its modern and flat design, the individual segments of the solar panel can be folded into a small bag and stored in luggage. Always ready for the next use.\u003cbr\u003e\u003cbr\u003eRobust, dust- and water-repellent materials\u003cbr\u003eThe durable Cordura fabric is extremely tear-resistant and flexible at the same time. It protects the valuable solar panel from damage and provides stability during use. The solar panel is dust- and water-repellent, so it can withstand most weather conditions, making it ideal for almost all outdoor activities. However, the solar panel should not be exposed to direct rain or heavy moisture.\u003cbr\u003e\u003cbr div=\"\"\u003e\u003cdiv\u003e\n\u003cbr div=\"\"\u003e\u003cdiv\u003e\u003cb\u003eIMPORTANT NOTE\u003c\/b\u003e\u003c\/div\u003e\n\u003cul\u003e\n\u003cli\u003eThe solar panel does not have an integrated charger or charge controller.
