powkey Foldable Solar Panel 40W Monocrystalline Solar Panel with USB QC3.0 Port/DC 12-15V Output Solar Charger for Power Station Mobile Phone Tablet Outdoor Camping

Convenient size, sturdy and strong build. This charges my power banks as well as mains electricity if in full sun. Even in low sun it trickle feeds power, which is more than I can say for the larger double panel solar charger that I normally use. Very good for travelling if space is an issue. Not lightweight, but I'd rather have strong than flimsy.

Ok so I got this last year and have only now got round to testing it. Max power I’ve had out of it is 25 watts however it charges my portable 240v battery packed in a few hours of weak uk sun. The 12v output can be used in tandem with the usb socket, the usb power is recognised as a fast charge source on my iPhone 16. I’m ordering another soon.

Absolutely brilliant, I brought this for my camping trips and obviously gave it a try before going away and it’s charged all my power banks even on a cloudy day it charged,gonna be a god send, folds up perfectly, has a little weight to it but nothing major.

Apologies if previous review was listed, bit of mix up on my behalf. Delivered on time and so far so good. Feels like a quality product, packs away nice and easy, lots of connection options 2xUSB 1xDC. Am using a Powerkey mini portable power unit (came on a bundle offer)on a cloudy day and am getting a slow steady charge. For my first tentative step into the world of solar, this has been a pretty painless and positive experience. Ideal for camping trips or a shed for keeping bits charged(tools,phone/tablet,fan etc) Definitely recommended.......so far

This is brilliant having 4 children they all have phones so going camping this is able to charge phones, chargeable lights etc. It's easy to use, and very portable. Its a game changer for camping.

I tried it straight away, and it charged my smart phone from 16% to 100% within two hours on a sunny afternoon. This is roughly the same as mains electric. The panels look well made, and it is neatly designed. It is large when opened out, but the size of a large laptop case when folded. So far I am very happy.

I used this to charge a 20,000 powerbank while on a 2 week walking safari in Africa. We strapped the panel to the top of a camel and it managed to charge the power bank fully everyday. I would suggest using small caribenas to attacht it as they eye holes aren't particularly strong for day to day use. Overall I recommend this solar panel.

It was very well presented and looked well made. I really liked how compact it was turning into a little carry case with built in legs and a built in zipped pouch for cables. I attached it to the power bank and with 20 hours of direct sunlight, over three days, nothing happened despite all of the appropriate lights correctly illuminating. I returned the item.
