Hoi Sandra! Auch wenn das Solarpanel nicht so viel geladen hat, ist's bei dem geringen Gewicht gar nicht so schlecht. 🙂 Und obwohl wir nicht bei Temu bestellen, finden wir's aber auch nicht schlimm. 🙂 Fijne avond! *Tot ziens!* _Vroni & Micha_
@@wanderverliebt hoi Vroni und Micha. Ich weiterhin auch nicht. Das Solar panel von Decathlon reicht sehr gut aus und bleibt deswegen auch bei uns. Fijn weekend. Liebe Grüsse Sandra und Ravi 🐾
I live in the US California were a lot of good sunny days. There is no issues charging a cell phone, small flashlight or even an arc type cigarette lighter. What is the issue with this type of solar panels (Temu and Aliexpress sells them but the same ones are on Amazon and eBay for a higher cots) is the max wattage claims. In the absence of a way to test them just don't believe the claims. Right now the 4-panel version you tested is said to be 40 watts (I have the exact same one even down to the camouflage color). I have a USB watt and voltage meter that plugs in(bought from Temu). The short story is that the device that is being charged is what decides on the watts it needs unless the watt capacity of the solar panel is exceeded. So in you test you don't know what watts your power bank was taking in. On my cell phone the wattage draw has not gotten higher than 1.9 watts and as you approach full charge goes down to 0.4 wats. The phone is what controls how much it takes in. I tried a radio that has a power bank in it and the most watts pulled by that was 2.9 watts. That was the highest wattage used to charge of any of the devices I have. So over time the panel is more than sufficient for that. I have been looking on the internet on a way to test the max wattage of the solar panels and the only one I have found is that you need to look at the max voltage and either a known load or a variable load (the vid I watched the guy had an electric load tester with an adjustment on it). So you watch the voltage and gradually increase the load. When you see the voltage decreasing you have approximated the max load that the solar panel can put out. When you do that the load tester might be in amps and you need to convert that to watts.
@@theoutdoordogandhikinggirl I am just starting to learn this stuff. I have like 5 of the temu small folding panels with 4-fold out panels in each one. The size of the panels does not match the over estimation of the possible wattage the seller tells you they are. As an example, 2 years ago the 4-panel folding one was listed as 20 watts. Now the same panels are listed as 30 watts. With no way to test them there is no way for the buyer to know. I am viewing this one on how to test solar panels. th-cam.com/video/q4XwpCmEarU/w-d-xo.html

@@Peterinnerbickler wow, that is a very useful comment! Thanks a lot for taking that time.

@Peterinnerbickler thanks, I will check that one out as well.
