BRESSER mobile solar charger 40 watts with USB and DC output

Independent trips with the BRESSER solar charger

Whether camping, sailing, hiking, or swimming by the nearest lake – anyone who loves to be outdoors for a long time doesn't want to be without a smartphone, tablet, power bank, etc. However, one question quickly arises: where to find the nearest electrical outlet? After all, every battery runs out, and our practical daily helpers cannot do without electricity. By using the extremely compact BRESSER solar charger, you simply use solar energy to charge your devices. Environmentally friendly solar energy is free – and you will remain independent of the power grid!

Just open it, place it, and immediately create green solar energy

The operation is very simple: unfold the solar panel and align it as perpendicular to the sun as possible. Then, connect the device to be charged to the solar charger using a suitable USB cable (not included) or the included DC connection cable. The charging process starts immediately.

Which devices can be charged with the solar panel?

The solar charger instantly powers all devices with a USB power connection or the aforementioned DC power plug connection – e.g. smartphones, tablets, power banks, portable playing stations, MP4 players, GPS devices, and Bluetooth headphones. For larger electrical devices, we recommend more powerful BRESSER solar panels with an output power of at least 60 watts – see no. 3810050, 3810060, 3810070.

Universal charger with flexible connection options

There are two black USB A ports for standard charging and one additional orange USB A port with QC3.0 standard for fast charging of newer generation devices. The package includes an additional universal connection cable with a hollow 5.5/2.1 mm diameter and a 2.5-meter long DC plug, 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 connections 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 display the current battery charging status on the screen or status LEDs. The charging process is also automatically stopped by the internal charger of the smartphone or tablet, etc., as soon as the battery is full.

Nevertheless, it is useful to know how long a full charge theoretically takes when the battery is empty. This is the only way to choose the right solar panel model that meets the requirements of the devices you want to charge.

Here’s a quick calculation: divide the battery capacity (mAh) by the charging current of the charger (mA) and multiply it by the coefficient 75. You will then get an approximate charging time in minutes needed to fully charge the battery operating at 100% sunlight.

Example: a battery with a capacity of 3000 mAh (3.0 Ah) and a charging current of 3100 mA (3.1 amps) via a 5-volt USB connection. So 3000 : 3100 x 75 = 73 minutes. Dividing the result by 60 gives the charging time in hours: 1.2 hours.

This means that an average smartphone can be fully charged in just 1.2 hours with a 40-watt solar panel.

Included carabiner hooks for attachment

To securely attach the solar collector to an object and perfectly align it with the sun, the package includes 4 sturdy hooks. Simply attach them to the riveted eyelets of the solar panel and hang the solar charger securely, e.g. on a tent loop, fence, or other suitable storage locations.

Innovative solar cell technology with high efficiency

Monocrystalline silicon cells ensure high efficiency and the fastest charging of device batteries. This means the highest electrical output per solar surface. As a result, you benefit from a relatively high charging current and short charging time due to the compact design.

Easy transport

Thanks to the modern and flat design, you can easily fold individual solar panel segments into a small bag and fit it into your luggage, saving space. Always ready for the next spontaneous use.

Durable, dust, and water-repellent materials

The durable Cordura fabric is particularly tear-resistant yet flexible. It protects the valuable solar panel from damage and ensures the necessary stability during use. The solar panel is dust and water-resistant, withstands most weather conditions, and is an ideal companion for almost all outdoor activities. Nevertheless, the solar panel should not be exposed to direct rain or high humidity.
