The ALLPOWERS 100W solar panel is conveniently foldable and can therefore be taken with you on the go. It was precisely for the latter purpose that I personally wanted to try it out, as I often go on day trips and spend a lot of time in nature. But I also think it's not a bad idea to have a solar panel like this at home in case of an emergency. The fact that a major power outage could theoretically occur is no longer completely unrealistic, especially in today's times. This is a foldable monocrystalline solar module which makes a solid and well-made impression. However, at 2.1 kilos, it is relatively heavy, so it might be a bit annoying to take with you on a hike or bike ride. The dimensions of 32 x 19 x 8 cm are not necessarily that compact and handy. The solar charger has an 18V DC output and has a high conversion efficiency of up to 23.5 percent, which is quite good comparatively. Even in higher heat, it still provides enough power. And it continues to charge well even when the sky is overcast and the sun doesn't come through quite as well. It is possible to combine this panel with the also portable ALLPOWERS 154WH/288WH/606WH power station and thus assemble a portable solar generator system from it. In my opinion, this would be a very useful option, especially in the event of a longer power outage, in order to still have some power available. The scope of delivery includes 1 DC 5.5 x 2.1 mm to 5.5 x 2.5 mm cable, a 1.5 m crocodile clip cable, a USB cable, a carabiner and an instruction manual. What's great is that you can hang the panel up using the included carabiners if you wish. I also find it positive that you can charge several smaller devices at the same time on the panel. The manufacturer also offers an 18-month guarantee, which I also find positive and trustworthy. Charging my smartphone works really well and quickly enough with the solar panel. There are no interruptions and no overheating. I am therefore very satisfied with the device and therefore give it a full five stars overall. ⭐️⭐️⭐️⭐️⭐️
