Self-sufficient travel with the BRESSER solar charger
Whether camping, sailing, trekking or swimming at the nearest lake – anyone who enjoys being outdoors for long periods of time does not want to do without their smartphone, tablet, powerbank, etc. But one question quickly arises: where can I find the nearest power socket? After all, every battery runs out and our practical everyday helpers can't manage without electricity. With the ultra-compact BRESSER solar charger, you simply use the power of the sun to charge your devices. The environmentally friendly solar energy is free of charge – and you remain independent of the power grid!
Simply open it up, put it down and immediately produce green solar powerThe handling is very simple: unfold the solar panel and align it as perpendicularly as possible to the sun. Then connect the device to be charged to the solar charger, either with a suitable USB cable (not included) or with the included DC connection cable. The charging process begins immediately.
Which devices can the solar panel charge?
The solar charger gets all devices with a USB power supply connection or the above-mentioned DC power plug connection up and running again in no time – e.g. smartphones, tablets, power banks, portable playstations, MP4 players, GPS devices and Bluetooth headphones. For charging large power stations, we recommend the more powerful BRESSER solar panels with at least 60 watts output power – see art. no. 3810050, 3810060, 3810070.Universal charger with flexible connection optionsOne USB-A connection socket is available for powering your devices. There is also an additional universal connection socket for DC bar plugs with a diameter of 5.5/2.1 mm. A universal connection cable with a 5.5/2.1mm DC bar plug on both sides and a length of 2 metres, as well as 3 plug adapters (3.5/1.35mm, 5.5/2.5mm, 8.0/5.5/0.8mm) are included in the scope of delivery. The polarity of the connectors is as follows: Inner contact = positive (+), outer contact = negative (-).
How long does it take to charge a battery?Most modern devices with built-in batteries indicate the current charging status of the battery on a display or status LEDs. The charging process is also automatically terminated by the internal charger of the smartphone or tablet, etc., as soon as the battery is full.Nevertheless, it is helpful to know how long a full charge theoretically takes with an empty battery. This is the only way to choose the right solar panel model for the requirements of the devices you want to charge.Here is a short calculation: Divide the capacity of the battery (mAh) by the charging current of the charger (mA) and multiply this by a factor of 75. This then gives you the approximate charging time in minutes that is required to fully charge the battery at 100% sunshine duration.Example: A battery with a capacity of 3000mAh (3.0 Ah) and a charging current via 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.This means that an average smartphone can be fully charged in just about 1.6 hours with a 21-watt solar panel.
Carabiner hook for attachment included
In order to attach the solar panel securely to an object and align it perfectly with the sun, 4 sturdy snap hooks are included in the scope of delivery. Simply connect them to the riveted ring eyelets of the solar panel and use them to hang the solar charger stably, e.g. on a tent loop, a fence or other suitable holding points. If you attach it to your backpack, you can even use the time during a hike for charging.
Innovative solar cell technology with high efficiency Monocrystalline silicium cells ensure high efficiency and the fastest possible charging of the device batteries. This means maximum electricity yield per solar surface. As a result, you benefit from relatively high charging currents and short charging times with a compact design.Easy transportThanks to the modern and flat design, you can easily fold the individual segments of the solar panel into a small bag and stow it in your luggage while saving space. Always ready for the next spontaneous use.Robust, dust- and water-repellent materials The durable Cordura fabric is extremely tear-resistant but still flexible. It protects the valuable solar panel from damage and provides the necessary stability during use. The solar panel is dust- and water-repellent, it withstands most weather conditions and is your ideal companion for almost all outdoor activities. Nevertheless, the solar panel should not be exposed to direct rain or extreme humidity.IMPORTANT NOTESThe solar panel does not have an integrated charger or charge controller. Therefore, it is not suitable for directly charging loose battery cells or lead batteries. It is only suitable for smartphones, tablets and power banks, for example, because they always have built-in internal chargers.The solar panel does not have its own battery, but serves exclusively as a power source in sunshine for charging electronic devices.When connecting the devices to be charged via the DC bar plug, always ensure the required voltage and correct polarity. Otherwise, damage may occur to the electronics of the solar panel and the devices to be charged.Do not leave the solar panel outdoors at night with high humidity or in the rain.

Discover the fascinating night sky - people have been drawn to the night sky since time immemorial. The BRESSER 90/900 Space Explorer telescope will show you the wonders of space. Thanks to the 90 mm aperture, the telescope collects 165 times more light than the human eye. The long 900 mm focal length brings the highlights of the night sky into view. Discover the Earth's natural satellite, the moon, take an optical trip to the planets, or journey past the solar system and discover the first bright deep-sky objects. The refractor telescope is mounted on a sturdy aluminium tripod to ensure maximum stability during your observations. There is also an accessory shelf for storing eyepieces, a Barlow lens and other accessories. You can also compensate for the Earth's movements to ensure that your celestial discoveries stay within the field of view: the equatorial EQ3 mount allows you to guide the telescope manually and follow your objects on their journey through the night sky.
Space Explorer telescope - everything you need for a good view into space
Designed for beginners and advanced observers, this telescope has everything that you need to explore space on clear nights. The red dot finder provides an easy way to orientate yourself in the night sky. Once you have set up the finder on the telescope, the small red dot will show you the direction in which your telescope is pointing. Once you have decided on an object, you can view it more detail with the three eyepieces. Marvel at Saturn's majestic rings and the gas giant Jupiter in different magnifications with the 4 mm, 12 mm and 20 mm eyepieces. On dark, moonless nights, the brightest gas nebula, galaxies and star clusters are also visible. If you're fascinated by the moon, simply screw the moon filter into the back of one of the eyepieces. This reduces glare and increases the contrast so that you can enjoy the Moon's stunning landscapes without being dazzled. You can also use the refractor telescope for terrestrial observations. Discover the wonders of nature and view distant animals up close!
