Doesn’t work at all in cloudy weather. Couldn’t get USB-C to happen for more than a second or two at a time, I think it requires more power than this can usually provide. Even in full sunlight in a window it charged very slowly for a short time and then the angle was not good enough. I have other cheaper solar chargers that still work in cloudy or not 100% sunlight coverage rather than completely turning off. I bought this to use in a car on long trips and it will not work for that. It will be returned.

This charger is built to be very durable and is built using high quality monocrystalline cells which means the cells are more efficient and work better at temperature extremes. I really like the construction of this charger, it is stiff enough to hold it’s shape when you want to stand it up or lean it, and flexible enough to drape over curved tent, car, etc. The charge controller seems very smart about turning off and on when enough light is available and also I appreciate the led to show when it’s charging. The charger is lightweight and folds down to a nice size for stowing in backpack or briefcase. I used the charger to charge my backup battery or directly charge my phone.
The sun is the main challenge with solar chargers – you often need to be creative to place panels to get the most light, and this charger has eyelets at the corners for anchoring with carabiners, cords, etc, so I’m always able to find a good position to maximize the charging. I used the charger while on a motorcycle camping trip and was able to use the tent or the bike to hold the charger, and I was able to strap it over my tailbag to charge while riding.
I also appreciate that there is no battery – I prefer to keep the battery separate since then I can choose what battery to bring or just charge my devices directly. Also these panels should last much longer than the battery cells would.

De zon moet wel goed schijnen en je moet alle 3 de flappen in de zon hebben. Maar dan laat hij prima een telefoon op. Ik had hem aan mijn rugzak hangen met fietsen en dat werkte prima.

I’ve decided that in order for these things to really be practical and worth my while, 28w is about as low as is reasonable to start with. This particular solar panel is fantastically made, it simply isn’t as efficient as I need it to be. At 20w, it takes forever to charge a battery pack, whereas if I start with a solar panel that is only slightly more powerful at 28w, I start experiencing (what seems to me) charge times similar to a wall outlet.

Il pannello solare da 20 W che ho testato è un prodotto di alta qualità che offre una soluzione efficiente per la produzione di energia pulita e rinnovabile. Il pannello solare è compatto e leggero, il che lo rende facile da installare su qualsiasi superficie piana, come un tetto, un camper o un barca.
Ho trovato che la produzione di energia del pannello solare fosse piuttosto impressionante, soprattutto in condizioni di sole diretto. Anche in condizioni nuvolose o in ombra, il pannello solare è in grado di produrre una quantità significativa di energia, il che lo rende un’ottima scelta per chi cerca una fonte di energia affidabile e costante.
Il pannello solare è anche abbastanza resistente e robusto per resistere agli elementi e alle intemperie, il che lo rende ideale per uso esterno. Inoltre, il suo design elegante e moderno si adatta perfettamente a qualsiasi ambiente.
L’unica cosa che potrebbe essere migliorata riguarda la sua capacità di immagazzinare energia, il che significa che il pannello solare potrebbe non essere in grado di alimentare dispositivi ad alta potenza per lunghi periodi di tempo. Tuttavia, se utilizzato con un sistema di batterie adeguato, il pannello solare è in grado di fornire energia affidabile e sostenibile per le attività quotidiane.
In definitiva, il pannello solare da 20 W è un’ottima scelta per chi cerca una fonte di energia pulita e rinnovabile. Con la sua produzione di energia affidabile e la sua resistenza alle intemperie, questo pannello solare offre un’ottima soluzione per qualsiasi situazione che richieda una fonte di energia autonoma e sostenibile.

I use it to charger portable batteries, that I then use to charge my gadgets (to keep them out of the sun, and it seems to charge the batteries faster than hooked up directly to the device (like my phone).
If you’ve got very bright sun, it actually charges pretty fast; I can charge my 20,000 mAh battery from 0 to 100 in maybe half a day.
However if it’s ANY bit overcast, that speed drops off a LOT. Now obviously it’s to be expected to not charge as fast when cloudy, but even slightly cloudy, it probably drops off by 50%, and a fully overcast day, it’s more like 90% (I can maybe charge that same battery by 10% in the same timeframe).
What a great price for such advanced portable solar cells like one of those old facial Tanners used to bring to the beach years ago OK that didn’t help anyone younger who have no idea what I’m talking about . Very powerful I left him outside for 15 minutes with my phone and it’s fall in that time it had bumped my cell phone power from 50% to 86% granted I had shut the phone off but that’s quite amazing

I like how light the unit is and it works as described. I set under a shade tree and was still able to charge my ipad pro. great for backpacking. I do wish that there was some sort of dust cover or protection for the USB port to keep any possible rain or dust of the port. you can buy a pack of those cheap though: https://www.amazon.com/Onwon-Rubber-Female-Protector-Stopper/dp/B01IY1Y6UG/ref=sr_1_5?crid=22M6SBPLAMJO3&keywords=usb+A+dust+plug&qid=1671012081&sprefix=usb+a+dust+plug%2Caps%2C140&sr=8-5
