Description
GROWATT 100W folding solar panel uses monocrystalline silicon cells and multi-layer cell technology, it has a high conversion efficiency of up to 22% and features 2 adjustable brackets that can be placed firmly on any ground. The angle between the panel and the ground can be adjusted from 45° to 80° to precisely capture the sunlight.
It also features the MC4 connector which is not only suitable for GROWATT power stations but is also compatible with most other brands of portable power stations.
It features a one-piece design, ETFE membrane, IP67 waterproof rating, scratch and weather resistance, and is suitable for all kinds of outdoor weather.
Weighs only 7.93 pounds, the folded dimensions of 23.7*21.2*0.98 (L*W*H) inches make it easy to carry. You can put it in the bag, your RV, camper or anywhere else.

I charged a 10,000 mAh powerbank throughout the day today in early March. The power fluctuated greatly due to trees in the course of the sun. But in the evening the powerbank was charged. I would certainly also create more if I had placed it better and followed the sun. But can not say for sure. My claim with little effort to charge a medium-sized powerbank it has fulfilled. The smartphone (pixel6pro) directly charge has not worked. What it is I can not say. Maybe the cable was wrong or the voltage has fluctuated too much. But the “stupid” powerbank had no problem. So it is for my zweack on more useful. The powerbank can be stored practically in the pocket.

Had bought the part for emergency. I have tested it a few times, but under less than optimal conditions. If the sun fits, the charging performance is fine. Shade immediately falls very much into the weight.

I must say, buying this product was one of my best decisions. With the solar panel here, we have been able to go 85-90% without charging through electricity for the last 2-3 months and almost only use powerbanks to charge all of our devices (about 6-7 of them). We are very satisfied with it.

Works great, charges my Galaxy Edge S7 even in on mode (i.e. GPS tracking enabled, no power save mode) and on cloudy days – only in the forest it gets (partially) too dark.

I bought the solar charger out of curiosity and used it to fully charge a 20,000mAh powerbank in October 2022. Very handy is the built-in ammeter, which showed up to 2.1A charging current in bright sunshine. All in all, my powerbank was fully charged in 3 days under varying cloud cover, which can certainly be shortened considerably in better weather.

I bought this portable solar panel with 28 watts some time ago and have now decided to write a review about it this device really has a super function over the USB-Ports can be charged randomly a powerbank or a smartphone I recommend at the point first a powerbank to charge because every now and then the current flow due to the not constant sun breaks in a powerbank copes with such a thing with the charging electronics much better than a smartphone where the battery may also still be and the smartphone is not only 20 or 40 euros but a few hundred euros so my recommendation Powerbank before over the solar panel charge and if the Powerbank the current has abgefasst over the Powerbank at night when it is dark no more current flows to charge the phone so I handle this always on festivals.

There was full cloudless midday sun today on 12/31/2019 at my location in Germany. I first just plugged in my new Samsung Galaxy A 70 smartphone. The ammeter shows a maximum of 1.7 amps. What many do not know. The maximum current that flows is only as much as the connected device wants to draw. So I connected my predecessor Samsung A 7 (2018) to the other USB port as well and lo and behold, it showed 2.4 amps on the display. After 10 minutes, both smartphones had about 10 percent more charge. The A 70 has a 4400 mAH battery and takes about twice as much per time unit as the battery from the aforementioned A 7. I judge this performance to be considerable and think even more comes in the summer with vertical midday sun. The panel’s pocket should be about 1 cm larger. The A70 needs an angle U-SBC connector to fit in well when connected. However, it is also very large at 6.7 inches.

Charging function very good and the built-in ampere display very helpful in the alignment. In conjunction with the sunny-bag powerbanks (which, unlike conventional powerbanks also tolerate voltage fluctuations, which are normal for solar panels) an ideal combination. Cell phones and Co I would never charge directly via the panel anyway, because they are often very sensitive to the above voltage fluctuations. So only charge via the charged powerbank. So that the powerbanks in the bag do not get too hot when the sun hits the panel I have a small white towel fixed by clothespins over the same. I am very pleased with the product and can clearly recommend it!

Have it also when hiking times had and attached to the backpack. Sure that’s not perfect but even here solang one pays attention that it hangs in the sun it works great. So far, clear recommendation.

fully recommendable. in the desert many cell phones loaded, many in our group have benefited from it. had concerns wg. german sun, have recently also tested here, with my reordered part, because I have left the first to the bedouins, also so that they do not always charge the smartphones via the car battery and in the silence of the desert run the off-road vehicle daily for about ne hour to charge the car battery. also works here with winter sun, fast and reliable …
