Review: Good buy, quality item. - Worked well for what I needed. I used this for a solar project for my son. It has all the connections that you would need and is very well made. Good price for a good item.
Review: Expected better quality - Purchased this on June 5th, 2025 for a solar powered weather station. Little over 3 months later, this is dead. Will not operate even if I plug in 5c USB cable into it. I could understand if this was 2-3 old but 3 months? Update: I am changing my rating as I was sent a replacement. Good customer service.

## Questions & Answers

**Q: if no power is going through the solar panel, can this be set to automatically turn on?  In other words does the 5v auto turn on when it gets dark?**
A: It automatically turns on when power is supplied from the panel. In the interim it draws from the battery.

**Q: How do i mount the cooling fin? is that what the 3m tape is for? and i it suppose to have direct contact?**
A: That is a good question. I didn't put on my unit and it is working fine.

**Q: what is the minimum voltage from solar panel needed? my location is partialy shaded so I get 5.5 in direct sunlight in morning and 3.5 in afternoon**
A: The minimum voltage required from the solar panel is 4.4-6V. In your case, you could connect a 3.7V Lipo battery at the BAT IN side. When the sunlight is not strong, the device can be powered by the lithium battery. When the sunlight is intense, the solar panel can power the device and also charge the lithium battery.

**Q: Open circuit voltage is 7.2V operating is 6 volts on my solar panels will this work with solar power manager 5 volt 6 volts max**
A: I had a little trouble with one of mine that had open circuit voltage above 6v. I opted for installing a step down circuit to drop it to 5v and it works like a champ.
