Review: Powers Orange Pi Zero 3 quite well - Using this with an Orange Pi Zero 3. It's working well. The power switch is a nice feature since the Orange Pi does not have one on the board itself. 5.1V is nice to give a little guard against brownouts that seem to plague these types of devices.
Review: Works very well and I like the on/off switch...But, not quite powerful enough for a Pi 5 - I suppose this works great on a Raspberry Pi 4 or earlier, but on the Pi 5 you get an error on boot that the power supply isn't 5-amps and some features will be limited. Assuming you don't need all the features or ports then it seems to work fine on this power supply. I got it to power a Companion Pi and it worked fine for that. I have since gotten a 5-amp one for the Companion Pi and now use this one for my Satellite Pi. My second Satellite Pi is powered by an even lower 1-amp power supply that came with it, and it too works fine for that role.

## Questions & Answers

**Q: If power goes out in my house, then comes back on.. do you need to push button to turn Pi on? Or will it start automatically?**
A: Hi. Yes. As long as the power is on, it will start automatically. Wishing you have a good experience with our product.

**Q: Does this work with the 8gig Pi4?**
A: Yes. This 5V 1A power supply is designed for raspberry pi 4. It can work with 8g pi4.

**Q: Could this ac adapter cause a dc offset when pi is being used for audio applications?**
A: I would say no.   The PIs do get finicky when underpowered and that may be an option here.   your audio may need its own power supply.   On my older PI I had the three contact phone jack and they tend to go bad as well.   Hope this helps.

**Q: Which country are the factories that made this product?**
A: Hello. This raspberry pi 4 power supply is made in China. Hope you have a good experience with our products!
