The best thing I’ve bought for camping and a full day at the beach. It charged my power bank, speaker, two phones, and flashlights without any issues during the day. It’s also waterproof (as long as you protect the USB ports), so you can also place it on top of the tent.

I had it all summer at a beach without electricity nearby and I truly never ran out of battery even for a moment on my phone, flashlight, and speaker.

Ideal for mountain excursions. I got it in case of a general blackout, see Spain... to charge my power banks. I am completely satisfied

Works as advertised but needs clear sky. It will work with slightly cloudy weather but it will take a lot of time charge a device.

I recommend avoiding charging a device directly because eventually the device will overheat. Prefer charging a power bank instead

After 3 years of use, I have the following to say.
1. It needs a long cable so the batteries can be placed in the shade.
2. The cable should be of good quality.
3. Always charge the power bank and not the phone because the power bank is designed to handle fluctuations in current and heat. The difference is huge!!!
If you charge your phone directly under the blazing sun, it won't charge!!! You need a power bank. The better the power bank, the better the charging! Make sure to plug the cable into the fast input.
I have 2 power banks and the power I get is about 60,000 mAh in 9 hours comfortably

Very good for camping with two ports. USB type c is very fast. You need to place it open and facing directly at the sun to get maximum performance. It is very handy for small devices in places where you don't have electricity. Small capacity as it becomes a small suitcase.

Very good quality although the charging doesn't seem to be 24w even with extremely sunny days and proper angle.
Also if it's too hot it's dangerous to put the device to be charged in the built-in pocket. You need a very long cable and set the device in shadow. They could work around this with a better insulated pocket

I won't say it doesn't work. But it doesn't seem effective to me. In 6 hours of exposure, barely 7% on a 30000 mAh battery.

If you connect a mobile, it keeps disconnecting and doesn't charge it either from USB or USB-C. If there's even light cloud cover, don't bother carrying it.

I bought it based on reviews as I had no experience, I don't recommend it as I find it bulky and with low output. If anything changes, I will return for re-evaluation in the future.

Excellent packaging, very good quality in the material construction, I tried it and with minimal sun it did exactly what it was supposed to do. I highly recommend it.

The best thing I've gotten for camping. When it hits noon, I unfold it to face the sun and charge everything on fast charge. At peak, I've seen it deliver 32W to the power bank (ugreen 100W 20000mah), which means it charges in two hours. This way, it doesn't need to stay for endless hours in the sun and sunbathe with me. The price may seem a bit high, but after the first summer, you might get a second one.

The best thing I have gotten for vacations and fishing. It charged my power bank, speaker, two phones, and flashlights effortlessly throughout the day. It is also waterproof and you can put it in a kayak or dinghy without fear

It covers the needs of two people for camping.. charges at about 3,000 - 3,200mAh per hour.. so a phone in an hour and a half.. a 20,000 powerbank in 6 hours.. reaches its maximum power during midday hours (12.00 - 16.00 measured in April month.. so this changes in the summer).. before or after these hours it charges much slower (around 500mAh) but don't worry.. it has two outlets, one type c (pd) and one usb, so you can charge two devices simultaneously without one delaying the other.

I used it during the summer and it was perfect.
Just be careful not to leave it in the sun and charging all day, until a little before sunset.
The only negative thing, if I had to say something, is that it doesn't charge 2 phones at the same time, but it charges one phone and another device normally!

Fantastic product. I charge my p30 Pro from 50 percent to 100 in about 30 minutes. With a USB C cable. Very good construction with 2 charging ports. You really have autonomy.

I have bought 4 and I am charging the redmi power banks. On cloudy days, it takes 4 hours to gather enough energy for a 60% charge. I also bought an hp notebook which charges from USB and I am fully dependent on the sun!! There is no longer DEI.

Fully satisfied with the performance in direct contact with the sun. For cloudy days, I cannot speak with certainty, but it was clearly slower.
