20W Solar Panel Charger Portable Foldable Fast Charging QC3.0 USB-A USB-C Output Small Power IP67 Waterproof Camping Backpacking Hiking Emergency for Phones Power Banks Flashlight Fans

Product is excellent. It will charge around 13,000 mah a day in full sun in Greece. Not sure about the UK, I can't imagine it will get anywhere close, but that's not the panels fault. Would recommend for use in full, stronh sunshine, but mileage will vary in places with less sun, lower strength sun etc..

Been using this solar panel while walking the camino through portugal and spain and has kept my phone etc constantly charged . it’s quite light robust and is a good addition to long distance hiking

I was a bit unsure how this product was going to perform due to the very reasonable price. After taking it to a weekend music festival it charged my devices very quickly in direct sunlight. 10/10 Great product for the price.

This worked reasonably well and charged my phone ok in bright sunlight but did take a few hours to go from 20% to full. Would expect would take longer if overcast though but as an emergency power source is a great addition to my assortment of gadgets. The build quality is quite good and I would expect it to be durable and long lasting and the supplied carabiner give the versatility of hanging it as an alternative to laying flat on a table which is how I used it laying it on the table of the balcony on a Cruise Ship. It has a USB-C and USB-A port and a small red LED that illuminates when receiving sufficient light to indicate it is charging your device but I think the two ports are to offer the option of charging either one A or C type device at a time as connecting two devices did not seem to work well. As a funny note I took this along with several other electronic devices on a flight but customs pulled me aside as they did not know what this was which was surprising.

Children's toy instead of charging my phone drains the battery even more

I bought this to use in Africa to charge our phones and power banks. It worked extremely well but we did have full on sunshine so cannot comment when used on a cloudy day.

Great in Spain

I bought this for a hiking trip in Greece. It is a nice size and the carbon fibre looks robust. I hardly used it on the first few days of my trip and unfortunately after pushing it in and out of my backpack over a few days I found that the charger was broken. I think that the with the way it is built that the circuitry is prone to damage. So that it. It's good but in actuality it is not very robust. I have written to the support and still after one week have not received a reply.

Bien, aurait aimé que la prise de rechargement soit mieux protéger

I can confirm that it weight 394 grams. In end of May, middle of Scandinavia with a hazy blue sky and some small passing light clouds afternoon I measured 6w around 1.7-2 amp. The panel has to be angled to the sun for optimal power output. I charged a Nitecore powerbank through USB-C around 25-30% I guess (from 1 dot to 2 dots) within 1h 30min. I think this 20w panel is a good compromise between weight and what power you get. If you are further south on the planet you might get the same power output from the flexsolar 15w panel, less weight? and smaller. The quality of the panel feels good and sturdy. I also have a 7 year old folding 24w panel with DC output. Through usb-a I got 9w more then 2 amp the same day. UPDATE: I used this panel above the Arctic pole circle middle of July to end of july. When the sun shined in the morning I placed the panel at right angle to the sun and could fully charge my powerbank in a couple of hours. I was surprised how well the panel worked. I packed it carefully and was gentle with it. The eyelets in the corners are definitely a point where wear and tare occurs. Not much on my panel but if I had hang it from my backpack I guess it would had taken a beating on those points. If there's no electronics near those eyelets corners it might not matter. Great panel and I'm keen to buy the 15w panel to use during summer hiking since this panel worked so well to save weight and space.

Erstaunlich, wie gut dieses Panel funktioniert. Gekauft für eine Radreise, wo Platz und Gewicht immer Thema ist.

Most small solar panels I have ordered only delivered about 1/3 (or less) of their advertised power. For the 20W FlexSolar I measured 14W in full sun from a port advertised at 15W, and was even able to pull 1-3W in overcast/rainy conditions (plenty for a headlamp/watch/e-reader). This is much better than I expected form a panel advertised as 20W. I wish the industry would be more forthcoming on real-world performance at the USB port, but this is the best power to weight ratio I have ever seen in a "backpack" panel - one of the few panels worth carrying, and the only one that actually delivered its advertised wattage (which is 15W, NOT 20).

I don't know much about solar panels, but I got this one for camping and for emergencies in case electricity ran out, to keep my phone, lamps and batteries charged. In direct sunlight, it charged my phone in about 2h, so that was perfect for me! It's also pretty sturdy and well built. It has hooks so I can hang it anywhere I want for the best angle, and it folds into a pretty compact size. I couldn't find any faults in it
