In the practical test, the Sunnybag LEAF MINI was particularly impressive when charging power banks. However, charging a smartphone directly was more difficult, as the current strength was often insufficient to ensure a continuous power supply in changing light conditions. Especially in shady areas or under cloudy skies, there were frequent interruptions, which made it difficult to charge a cell phone. Charging a power bank worked, but took a comparatively long time. Nevertheless, the panel’s auto-restart function offers a practical solution for unstable conditions.
The product was also impressive in terms of weather resistance. The panel proved to be waterproof and resistant, so that it works without any problems even in light rain or high humidity.
The material used is also extremely scratch and impact resistant, which ensures a long service life.
The connections are firmly and stably mounted, although the rubber cover for the USB port is missing on this model. A corresponding addition would be useful.
Thanks to its low weight and sturdy metal eyelets, the panel can be easily attached to rucksacks or tents without being a noticeable additional burden. Despite the robust design, however, the problem remains that even the slightest shadow or fluctuating light conditions can have a significant impact on charging performance. Anyone using the panel on the move or in changing weather conditions should therefore be patient. An additional power bank is therefore highly recommended for efficient use.
