»We are very impressed with both Sandberg solar modules after the first few months of use. Compared to the previous version, the new Lightweight series of solar modules represents a noticeable improvement. They are lighter and perform significantly better even under less than ideal conditions.«

»This charger's performance isn't just impressive in the sun — even in cloudy conditions, it can keep a laptop battery nearly full, even while under heavy use. So it's perfect for nature escapades where the skies aren't always clear.«

»My experience was that the percentages on the power bank I had connected quickly incremented, even though the panel was not optimally directed towards the sun. The same happened when I tested the DC connector with Sandberg's Power Station AC300. The pocket on the back of the panel is perfect for storing your power bank while charging. Sandberg Solar Charger 40W LightWeight is an update that actually fixes the few complaints I had about the predecessor, it is about 500 grams lighter, and can deliver a reasonable effect on the USB connectors, and at a slightly lower price!«

»The part that I am most impressed with is the efficiency of the panels. All panels, more or less, perform well under direct sunlight, but the Sandberg Solar Charger 40W LightWeight is also incredibly efficient under cloudy conditions. We tested connecting our Snapdragon X Elite laptop while working outdoors on a cloudy day, and despite using the computer at full load while it was charging, the battery remained at almost full capacity throughout the day.«
