Portable solar panel Bresser 21W with USB and DC output

Portable solar charger Bresser 21W with USB and DC output

Self-sufficient travel with the BRESSER solar charger
Whether camping, boating, hiking or swimming in the nearest lake, anyone who enjoys being outdoors for long periods of time doesn't want to be without their smartphone, tablet, power bank, etc. But a question quickly arises: where can I find the nearest power outlet? After all, every battery runs out and our handy daily helpers can't manage without electricity. With the ultra-compact BRESSER solar charger, you simply use the sun's energy to charge your devices. The environmentally friendly solar energy is free of charge and you remain independent of the power grid.

Simply open it, leave it and immediately produce green solar energy
The handling is very simple: unfold the solar panel and align it as perpendicular 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 starts immediately.

which devices can the solar panel charge?
The solar charger puts all devices with a USB power supply connection or the DC plug connection mentioned above back into operation in no time at all, e.g. smartphones, tablets, power banks, portable gaming stations, MP4 players, GPS devices and Bluetooth headsets. For charging large power stations, we recommend the more powerful BRESSER solar panels with an output power of at least 60 watts, see art. no. 3810050, 3810060, 3810070.

Universal charger with flexible connection options
A USB-A connection socket is available to power your devices. An additional universal connection socket for DC bar connectors with a diameter of 5.5/2.1 mm is also available. A universal connection cable with a 5.5/2.1 mm DC-rod connector 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) 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 integrated batteries indicate the current charging status of the battery on a status display or LED. The charging process is also automatically terminated by the internal charger of the smartphone or tablet, etc., as soon as the battery is full.

However, it is useful 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 brief calculation: divide the battery capacity (mAh) by the charger charging current (mA) and multiply by a factor of 75. This will give you the approximate charging time in minutes required to fully charge the battery at 100% sunlight duration.
Example: A battery with a capacity of 3000 mAh (3.0 Ah) and a charging current through a 5-volt USB connection of 2400 mA (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 about 1.6 hours with a 21-watt solar panel.

Carabiner hook for attachment included
To attach the solar panel securely to an object and align it perfectly with the sun, 4 sturdy safety 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, fence or other suitable attachment points. If you attach it to your backpack, you can even use the time during a hike to charge.

Innovative high-efficiency solar cell technology
Monocrystalline silicon cells ensure high efficiency and the fastest possible charging of the device's batteries. This means maximum electrical output per solar surface. As a result, you benefit from relatively high charging currents and short charging times in a compact design.

Easy transport
Thanks to the modern, flat design, you can easily fold the individual segments of the solar panel into a small bag and store 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 repels dust and water, withstands most weather conditions and is your ideal companion for almost all outdoor activities. However, the solar panel should not be exposed to direct rain or extreme humidity.

IMPORTANT NOTES

• The solar panel does not have a built-in charger or charge controller. Therefore, it is not suitable for directly charging loose battery cells or lead-acid batteries. It is only suitable for smartphones, tablets and powerbanks, for example, because they always have built-in internal chargers.
• The solar panel has no battery of its own, but serves exclusively as a power source in sunlight for charging electronic devices.
• When connecting devices to be charged via the DC bar connector, always ensure the required voltage and correct polarity. Failure to do so may result in damage to the electronics of the solar panel and the devices to be charged.
• Do not leave the solar panel outdoors overnight in high humidity or in the rain. This could damage the internal electronics.
