  I have 3 of these for beekeeping scales. They charge the battery with relative sunlight from 0 to 100% in 2 days, which is more than satisfactory for this use.

  It might actually discharge devices instead of charging them or at least keep the charging percentage stable.

  I wanted it for my mobile phone (small smartphone) and the radio for when I go fishing.
  It does its job perfectly fine!

  At first, I thought I would charge the phone directly from the solar panel. Not.... Smartphones are difficult to charge directly from the sun with an 8W rated panel, because they have high energy consumption with apps running in the background even when the screen is off. If you want to use it simultaneously, you have forgotten about it. Therefore, you charge a power bank that has minimal losses and use it to charge your devices. It will take you all day, but it will happen. As for small charges like rechargeable lamps, wireless headphones, and the like, it goes infinitely faster.

  On the plus side, it fell down, split in two, I put the pieces back together, and it works as if it never fell.

  It does what it says. It charges even in low sunlight (obviously with the corresponding speed). I use it to charge a power bank and then charge small devices like my phone, headphones, watch, etc. I don't regret buying it!

  Charges slowly but it was expected.
  Excellent for charging headphones, wireless gamepad, power bank, etc.
  On the mobile, it struggles a bit, it takes hours to charge properly.

  Very good for its price though, as an emergency solution for camping, etc

  With about €15 including shipping, it is a convenient solution through the sun if you are in a place without electricity (such as outdoor spaces, camping, beach, rooftop, or in cases of power outage, etc.) and at some point you won't have power nor the power bank to provide when it runs out. With this small photovoltaic panel, you can charge or power electronic devices via USB from 5V ~ 6V.

  It comes with a USB cable that includes multiple common connectors for various devices and mobile phones (microUSB, miniUSB, TypeC, Lightning for iPhone, as well as the 5.5mm DC barrel jack for electronic devices).

  BUT it is better to use your own USB cable (i.e., the one for your device) as it is of better quality and will have as little power loss as possible.

  Of course, don't expect much from a small photovoltaic panel and it promises 8W of power, which in practice, considering losses, cable length, etc., you should consider it as a clean output to USB of about 4W to 5W (if it is true that it has a 5V output and 0.74A current as stated by the Ampere application on the mobile phone) which I tested briefly in moderate sunlight. You might say it is a minimal current (it is approximately equivalent to old Nokia chargers), but if you turn off WiFi, Bluetooth, GPS, NFC, and close the open applications on your phone and leave it in the hot sun all day during the summer, it will charge. If you use it with the ideal power bank, it will take even more hours and the next day.

  Since I have had it for one day, I will re-evaluate it when I see it better.

  Update October 12, 2023 -> (9 am to 3 pm) with good sunlight, it charged a bit and charged the second out of the 4 bits that a total of 10000mAh Powerbank has, approximately 2500~3200 mAh. In very hot continuous sunlight, it gives its all, so you can understand that in cases of emergency or other situations where we don't have access to the DEH network, it does the job and can be a lifesaver. Imagine a panel with four times or even ten times the size, what power it would generate. The future of electricity through renewable free energy is photovoltaic with the sun.

  I don't know if I'm doing something wrong. My power bank, which is a regular 10,000 mAh power bank, doesn't charge, but it did charge a Nokia mobile phone (not a smartphone).

  After about a week, I have to report:

  Very good construction. Much better than I expected!
  Long cable.
  Stand to stand upright or lying down.
  I don't know if it's really 8W. The only measurement I have is through the Ampere program, where it showed my phone charging at 550mA with full midday summer sun.

  I will come back if I have anything else.

  Very good construction for its price. Not only does it charge smartphones in about 3 hours, but it can also work outdoors without any problem with USB-powered computer speakers. You can buy it with closed eyes, the product is worth every euro of it.
