## 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?**

## Customer Reviews

### ⭐⭐⭐⭐⭐ No complaints
*by S***G on April 21, 2025*

Came as a bundle but works as it should. Only took couple hours to fully charge. I recommend it.

### ⭐⭐⭐⭐⭐ works well for any business traveler
*by M***R on April 17, 2025*

This really helps when traveling and need portable power

### ⭐⭐⭐⭐ Good for emergency phone charging
*by M***I on August 28, 2023*

I got this, because it sounded like it would be compatible with my portable power box. I bought the box over a year ago, but hadn't gotten around to buying solar panels for it, because the ones that were supposed to come with it cost more than I could afford, and while I was saving up for them, they went up in price. This was a lot cheaper, so, even though it was visibly smaller, I figured I would just have to let it sit outside a little bit longer than the expensive panels, and it had all of these fancy adaptors, so I assumed that it would work. Unfortunately, none of the adaptors were compatible with my box. HOWEVER, it has a USB port, and works really good at charging a cell phone, as long as you have it in a good, sunny spot, and, since I have dealt with a vehicle that likes to overheat or blow a tire on hot days, leaving me stranded with a dying phone, I now carry this with me in said vehicle, for emergencies! So, it's great for that.
