## Description

SinKeu 40W solar charger panel for phone, laptop

Review: This solar panel Works phenomenally I even had to use it to act as an alternator for my Jeep while I was out weed eating a fence lines out in the country I strapped it to the top of my Jeep I put the converter inside my Jeep I made a makeshift wiring harness that ran to my battery and kept it charged so I could do my job I've also used it in many other applications it's versatile it's heavy duty and it was stands anything in the environment. It's it's extremely durable it's a very lightweight and it was a very very good value for the money I've been living off grid for some time now and it is always done the job I needed it to.
Review: The backing on the solar panels is a bit thicker than other solar panels but it will prevent cracking and damage which is great. It actually outputs over 30W which is incredible because most other sellers would list this as 60W in that case for portable foldable solar panels. The output is the biggest downfall of this solar panel. It only has one usb output and its 5v max which mean you’re getting a total of 10w out of the possible 30w. Huge waste . I got this becuase I have a Drok dual usb output buck boost converter which essentially adds more USB outputs to the solar panel but at a cost. I already had the converter so I’m not sure how it would add to your total cost of the system ~$20usd But would allow you to have 2 12v or 5v USB outputs that you could use at 12v 1.5A on two portable batteries or you could use the DC wire to plug into a Jackery battery, which is the method that I would recommend if it is applicable to you.

## Questions & Answers

**Q: Why the 40 watt solar panel can not produce desired power when charging my batteries?**
A: This is normal, the solar panel works fine if it could produce an output power. Actually 40W is the max power of the solar chips, and 40W is a tested result in a laboratory with very strong light. The small solar panels are affected by many factors

**Q: Is the solar charger panel compatible with all power stations?**
A: The solar panel comes with 10 DC adapters and is compatible with most portable power stations/solar generators on the market. However, I would recommend checking the input voltage range of your device to ensure it matches the 18V output solar panel.

**Q: It is recommended to charge how many watts of portable power staion?**
A: Because the DC output is 18V/2.27A, the higher the wattage of your solar generator, the longer the charging time will be. For example: 300W=300/(18*2.27)=7 hours approx.

**Q: Can it charge multiple devices at once?**
A: Yes, the 40W solar panel can charge multiple devices simultaneously. It has 3 output ports - 1 DC output, 1 USB-C output, and 1 USB QC3.0 output - that allow charging of different devices like phones, laptops, power banks etc. at the same time.

**Q: What's in the package?**
