Frequently Asked Questions

How much power does the Dulotec SC1 actually generate on a sunny day?

In direct sunlight, the Dulotec SC1 actually delivers between 1.8 and 2A of current. The panel’s rated power is 15W at an operating voltage of 5V. The actual current depends on the angle of incidence of the sun’s rays and the degree of cloud cover. For maximum output, it is recommended that the panel be positioned perpendicular to the sun.

What happens if the panels are shaded while charging?

The Dulotec SC1 features an automatic restart function. If a cloud passes in front of the sun or the panels are temporarily shaded, the charger stops supplying power. As soon as the light returns, charging resumes automatically—without the need to turn it on manually. This feature is especially useful in variable cloud conditions.

How many devices can be charged at the same time?

The Dulotec SC1 has two USB ports with different current ratings—5V/2A and 5V/2.1A. Two devices can be charged simultaneously. When charging two devices, the available power is distributed between them, which may slow down the charging speed compared to charging a single device.

Is the Dulotec SC1 rainproof?

The Dulotec SC1 is IPX4-rated, which means it is protected against water splashes from any direction and light rain. The charger is not designed to be submerged or exposed to heavy rain for extended periods of time. For hiking and outdoor use under normal weather conditions, this level of protection is more than sufficient.

How do you mount the Dulotec SC1 on a backpack or a tree?

The panel has 4 built-in mounting holes located at the corners. It can be attached to a backpack, a branch, a fence, or another suitable support using carabiners, a rope, or a rubber band. Positioning is quick and easy, requiring no additional tools. It is recommended that the panel be tilted so that the sun’s rays fall perpendicularly on it.

Does the Dulotec SC1 have a built-in battery?

The Dulotec SC1 does not have a built-in battery. The charger converts solar energy directly into electrical current and supplies it to connected devices in real time. The lack of a battery means there is no risk of overheating during prolonged use in the sun. Devices charge only as long as the panels receive sufficient light.

What are the dimensions and weight of the Dulotec SC1?

When unfolded, the Dulotec SC1 measures 68 x 29 x 1 cm. When folded for transport, the panel measures 29 x 17 x 1.6 cm—convenient for carrying in a backpack. It weighs 800 grams. The body is made of durable Cordura fabric, which provides good protection during everyday outdoor use.
