FlexSolar 20W Solar Panel Charger Portable Foldable QC3.0 USB-A/C Output

Last camino I brought a foldable solar-panel as well, but then the connection was so flimsy it broke on the last day. And it did not charge well. I have tried this one carried on a backpack and charging my phone. It charged it from 81% to 100% while walking towards the sun and through a wooded area around 50% of the time in about an hour and 10 minutes. So I will be bringing it. Should keep my phone at 100% and allow charging a battery/powerbank.

Effective solar panel - quickly charges battery packs in direct sunlight. It's easy to carry, folding up well and being very light. I've also used it attached over my rucksack with carabiners for power on the go, worked well!

Just charged a Samsung A53 from 59% to full in 50 minutes in South West Scotland. Used outside and tilted towards direct sunlight. Watch out for when there isn't much daylight as it then draws power out of the connected unit. Also brought a Lenovo M10 tablet up by 50% over 1.5 hours of evening sun.

I bought this to walk the Pennine Way. I didn’t expect much but it works. It doesn’t charge fast but it will give enough charge to a power bank over a day in the North of England in September to recharge an iPhone 16 and a Garmin watch. It is lightweight. If it were completely waterproof it would score higher.

Works well, seems sturdy

I returned it. USB-A port failed after a couple of days of use on an international camping trip. Spend a bit more on something of better quality.

Pretty good. Good for long outdoor walks but doesn't pump out alot of power which is a real shame does fold up flat

Seems to work fine, took it camping to charge phones off of a power bank. Panel kept the powerbank fully charged.

+ charges slightly even under overcast sky - prone to overheating (decreases charging speed and overheats the charged device placed under the panel) Suggestion to the manufacturer: would it be possible to make the next version from white / reflective plastic to reduce overheating?

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.

ce chargeur solaire a bien fonctionné pendant trois mois ! ce qui est un peu court, non ? aujourd'hui c'est fini plus de charge possible, visiblement il ne peut plus capter. Je trouve que vous devriez faire plus attention à vos revendeurs car je suis certaine de ne pas être la première dans ce cas. Que comptez-vous faire ? Me rembourser, remplacer ce produit ?

These work well, but don’t expect any kind of a fast charge in a pinch. Probably best to charge a powerbank with one of these at all times and then use the battery for your phone

I purchased for an up coming backpacking trip. I use the solar panel in conjunction with a battery bank to provide power to a host of electronics. It preformed flawless and even provided power on less than ideal conditions. It proved exceptional durable has it spend a days bouncing on my pack charging the battery bank I walked. The solar allow me to reduce my battery bank capacity. It was a great addition to my kit and I would recommend it. It is of great value to me to be able to provide continual power. The only improvement would be to put small silcone covers over the output ports to protect from precipitation. I always made sure to hang the panel with the ports in a downward orientation to protect from precipitation and I had no problems. Super easy to use.
