FlexSolar 40W Foldable Solar Charger, USB C Portable Solar Panel, PD2.0 QC3.0 DC Ports, IP67 Waterproof ETFE Power Emergency for Camping Hiking, Compatible with Smartphone Tablet Headphone Laptop

Fantastic quality, does the job perfectly. Many thanks.

Under direct sun close to the equator, my Mac book reported this as a 41w power connection! I have not tried any other power monitors. What I can say is everything was charging fast. I tend to use it on the beach, to charge a power bank, which runs a Starlink mini all day long! That setup keeps the kids happy with internet, which provides some peace. It’s a small panel, about the size of a Mac book 13. Easy to chuck in with other beach gear. Seems very robust.

Works well for me even in dull daylight Charging small devices phone/pocket power bank/headphones/camera only 1 at a time if not in bright sunshine.

Its enough to run 3 phones, 2 sets of wireless headphones, a 2 bike battery array (and occasionally a Samsung tablet + emergency power bank/bike battery booster and radio) for literally 24/7 (on a sunny day ofc, today was cloudy, so no tablet to preserve the charge). Does it output 19V? Nope, Best I saw was 12.8 via DC direct connection, however, that is still amazing and quoted cap is under ideal conditions). Folds small enough for a backpack (and has space in the middle when folded for the tablet, damn efficient) enough for off the grid living (until your batteries die as needs a buffer). Would have bought a second one if not for the price being raised from 35 to 50 squid.

I have used this to charge a Anker Prime 27,650 mAh Powerbank, it charges at around 25w which isn’t 40 but it’s still good. (I have only used the USB-C and USB-A, I am yet to use the DC 5521 (next review I will have). The output is more that what is said by FlexSolar which is great, no complaints there. It is a little expensive but for the purpose of being portable, it’s great. Very easy to use, it even has a red light which activates when the solar panel receives enough light to create electricity. Updated Review with DC & Anker C200: Yesterday, I charged 90% in a full day which adds up to 54,000mAh / 60,000. Keep in mind I also charged a full phone which adds up to around 3,500mAh. The solar panels are pretty decent, on a good day, in a good position you could get up to 31w through the DC cable. (It is a DC5521) I do consistently get around 25w in full sun, no clouds at around 90 degrees. It is a decent panel which does require strong amounts of sunlight. If you have the extra £10 (when on sale) I would definitely prefer to get the 60w rather than this 40w since the output is around 62% than what is claimed.

This product didn’t do what it said it would do. I tried to charge my smart watch and tablet. It did nothing in fact the battery on the tablet lost power. So I tried to charge the watch alone. It barely charged it to above flat. This was tried in full sunlight and on cloudy, still didn’t work.

Great backup solar charging, folding away nicely for storage. Fits across the dashboard of a Vw T5

My experience of this product is that it doesn't charge as quickly as expected. I have a similar 24w charger that is about 8 years old and it charges at about the same rate. I did a side by side comparison and my 24w handled cloud covered sun better than the Flex solar 40w.

Génial et pratique Sa légèreté permet de l'embarquer pour de grandes sorties en pleine nature

Pros: it supports fast charging. easy to carry , you can fold it Cons: it absorbs the sun heat aggressively Which will makes it slows down the charging speed , this is normal but really annoying because i have to wait more to charge my device

Have used this through two camping seasons. It has been amazing. I also bought a 30,000mah power bank to use with it. Have never run out of power for all our devices with this. Seems ruggedly made, sturdy. Folds up small and is easily stored. We use the solar panel to charge the battery bank/whatever else needs charging during the day, then at night we have the battery bank for anything else. We have 2 tablets, 4 phones, 2 JBL flip speakers and some rechargeable LED lights. This setup has worked for all of it. Pleasantly surprised!

Wij hebben deze zonnecel aangeschaft voor het kamperen met de tent. Wij gebruiken daar nooit stroom. Nu met deze uitvouwbare zonnencellen, kunnen wij onze powerbank opladen en daar weer mee al onze telefoons, reader's en elektrische tandenborstels opladen. Na ontvangst heb ik de zonnecellen even getest en in ongeveer 2 uren was de powerbank (22800) opgeladen. Was niet constant stroom. We zijn dus zeer tevreden.

Good at charging phones, batteries and laptops.
