With the autonomous BRESSER solar charger on the go, whether camping, sailing, trekking or swimming lake – those who like to stay outdoors for a long time want to access it via smartphone, tablet, power bank, etc. Do not give up. But quickly the question arises: where can I find the nearest socket? Because every battery is empty and without electricity, our practical daily assistants cannot go out. With the BRESSER Ultra Compact Solar Charger you can simply use the power of the sun to charge your devices. Green solar energy is free and you remain independent of the electricity grid! Simply unfold, put it down and immediately generate green solar energy. The operation is very simple: simply unfold the solar panel and position it as vertically as possible with the sun. Then connect the device to be charged to the solar charger, either by appropriate USB cable (not included) or with the included DC connection cable. Already the load begins. What devices can the solar panel charge? All devices equipped with a USB power port or the above-mentioned hollow DC connector are ready to use with the solar charger in a flash – e.g. smartphones, tablets, power banks, MP4 players, GPS devices and Bluetooth headphones. In addition, it is ideal for charging large power stations such as B. the Bresser 100 W power station (article number: 3810000) and the Bresser 500 W power station (article number: 3810020) as well as power stations from other manufacturers with appropriate connection values. Universal charger with flexible connection options To power your devices, you have two black USB-A ports for normal charging and another orange USB-A port with QC3.0 standard for fast charging of new generations of devices. In addition, an additional universal connection cable with hollow DC plug in diameter 5.5/2.1 mm and 2.5 m length as well as 3 adapters (3.5/1.35 mm, 5.5/2.5 mm, 8.0/5.5/0.8 mm) are included. The polarity of the connectors is as follows: inner contact = positive ( ), external contact = negative (-). How long does the charge last? Most modern devices with built-in batteries inform you of the current battery charge status via a display or status indicators. In addition, charging by the internal charger of the smartphone or tablet automatically stops when the battery is full. Nevertheless, it is useful to know how long theoretically takes a full charge with an empty battery. Because this is the only way to choose the right model of solar panel for the needs of your devices to charge. To do this, a small bill: divide the battery capacity (mAh) by the charging current of the charger (mA) and multiply it by a factor of 75. So you get the approximate charging time in minutes required for 100% sunlight to fully charge the battery. Example 1: a battery with a capacity of 3000 mAh (3.0 Ah) and a charging current per 5 V USB port of 3400 mA (3.4 amps). So 3000: 3400 x 75 = 73 minutes. The result divided by 60 then gives the charging time in hours: 1.1 With a 90-watt solar panel, you can fully charge an average smartphone in 1.1 hours. Example 2: A large power station battery with a capacity of 13000 mAh (13.0 Ah) and a charging current per DC port of 18 V of 5000 mA (5.0 amps). So 13000: 5000 x 75 = 195 minutes. The result divided by 60 then gives the charging time in hours: 3.3 with a 90W solar panel, so you can fully charge this Power Station battery in 3.3 hours. Mounting carabiner included In order to securely attach the solar panel to an object and align it perfectly in the sun, 4 sturdy hooks are included. Simply place them in the riveted eyelets of the solar panel and hang the solar charger stably, e.g. on a tent loop, fence or other suitable attachment points. Innovative high-efficiency solar cell technology Monocrystalline silicon cells ensure high efficiency and the fastest possible charge of the device's batteries. This means the maximum power per solar panel. So you get relatively high charging currents and short charging times in a compact design. Easy transport Thanks to the modern, flat construction, you can easily fold the various segments of the solar panel like a small bag and store them in travel luggage. Always ready for the next spontaneous use. Robust, dustproof and water-resistant materials The durable Cordura fabric is extremely tear-resistant while remaining flexible. It protects the precious solar panel from damage and ensures the necessary stability during use. The solar panel is dust and water resistant, making it resistant to most weather conditions, making it your ideal companion for almost all outdoor activities. Despite this, the solar panel should not be exposed to direct rain or high humidity.
