Ecosonique 30W/36W Portable Solar Panel Charger, DC19V, USB-A QC 3.0, USB-C PD 24W with Detachable Power Hub, ETFE IP67 Waterproof Foldable Solar Charger for iPhone Samsung Power Bank Power Station

I took this out for a week of wild camping in Scotland--pretty much the most extreme use case I would envision for the solar panel and it performed adequately. The design is very intuitive. There are nice holes to tie to your backpack as you're walking. I would say it really charges at 30W. It fully charged the battery bank in anywhere from 4-8 hours depending on my orientation directly to the sun and it charges all of my other devices admirably. For the amount of power the panels draw, I would say that the <1kg for the panel along makes it great for backpacking if you are a more digital person but still want to be off-grid. Now comes to the battery bank. 10/10. I was imagining a cheap low quality backup battery but this is just as good as any highly rated battery banks. It charges my iphone 13 mini 3.5-4 times. The usbc cable attached to it is bound by very strong rope and also functions as a loop to attach to your karabineer. Neat concept! Overall the battery is a very well thought out product and performs as a regular 20k mah battery. Considering other panels are going for the same price without a battery, this is such a nice bonus and value for money!

One of the most important thing to carry with you when travelling to the EBC is the solar panel. Unfortunately charging your phones or power bank is n thquite a lot at the tea stalls - around 2-3 dollars per hour is what people say. So by the time you spend that much amount of money some tend to travel with the solar panel, as you can charge the devices on the go. So having this adds value for money in the long run. I have carried out couple of tests to make sure i am satisfied before taking this along. it has 2 connection - USB C and USB A. You can only charge with one port, the 2nd port won't charge the device, instead the power on the 2nd device will fluctuate and as a result both device shut off eventually leaving for no charging. It is quite sturdy, better than the one I had bought from decathlon. the size of the panels are quite decent and light weight. It did provide enough power to the power bank in the UK sunny days we had in the past couple of days. The only thing that lack in the product is a pocket of a mesh to keep your charging device at the back of the panel - like a pocket, you will see that in the decathlon solar panel kit. Rest from the fucntionality wise it all looks good for now.

It is well built, and weather proof (although the USB unit will need to be kept dry). On a sunny day in the UK it can produce enough power to charge an iphone, however it is slow so I used it to charge a USB battery which then charged the iphone at night from the battery. If it is overcast (or not summer) your charging mileage will vary. More useful on a long camping trip otherwise a good USB battery is cheaper and will keep a phone running for a few days anyway.

Bought the 60 after the 15. The 15 is excellent value and works well for me in a variety of light conditions, charging my phone and battery packs fairly quickly depending on the light conditions. I bought the 60 thinking that this would charge them quicker especially in poorer lighting but have been shocked to find that it is much slower than my 15. I have checked out both in the same lighting conditions and the 15 definitely works better for me and faster. The 60 really struggled in poorer lighting conditions and was slower in all light conditions. Very disappointed with the 60 but love the 15!

Great bit of kit to keep items charged and my power pack topped up. Nice size and easily stowed away.

I wasn't sure what to expect with this. Would it promise to work, but not really charge anything. Well I have had it a week now and we have had plenty of sunshine, and I have generally been able to charge 3x10,000mAh battery packs per day with minimal repositioning of the panel towards the sun. This was better than expected, as was the build quality. If you were camping and are not going to have electrical hook-up for days, you could easily charge all your power banks to plug other items (including phones) every night.

Ordered two panels and this was the best of the two It does produce some power in lower light conditions, and the orientation to the sun only makes a couple of watts difference, so great if you can't orient them correctly (i.e. bike packing or walking). I tested this vertically at 1pm and was still getting 10w out of one USB. (I didn't try both USB ports) This panel also works better in dappled shade than other panels, and partially covering one panel drops the power output but it still remains. The other panel I bought did not produce any power with my hand in front of one panel while there was direct sunlight on the others However, there was a maximum of 10w per USB output in full sun, not 15w as advertised. The panel does advertise to only use one at a time, but I could get 10w out of both USB connectors in full sun. My home solar panels at this time at the same angle were producing 90% rated capacity, not 66% like these Three star review because of the false advertising. The listing should be for 20W as maximum output, not 28W

Took this camping with us, it plugged into the Powerbank we had with us without issue and charged it quite quickly even though it was slightly overcast. It seems fairly sturdy, but I would still treat it delicately as I can see it breaking if abused. I do need to find some way of protecting it during transport as the delivery box will not be sufficient for long term use. Is worked well and I'm happy with the price.

This is a very handy solar array. Its small enough to sit in a sunny window and charge my phone.
