## Questions & Answers

**Q: Is the voltage selector knob fitted with position detents? Can the selector knob get easily bumped to the wrong voltage?**
A: Dear customer,
The rotation control is not loose and will not switch to other voltage positions unless it is turned by an external force.

Have a good day!

**Q: What is the actual tested, rated voltage/current for the USB-C tip? Seems like it is a 5V tip.**
A: Dear customer,
The USB-C tip has no rated voltage/current, the output voltage and current mainly depends on your device.
Wish you have a good day,
Meiyue

**Q: Does the selection knob lock in to position? It seems like I could plug in a low V device, have a pet bump the knob, and fry the device being powered?**
A: It doesn't lock.

**Q: How can you determine the amps it is putting out?**
A: This supply is rated at 3 amps, the only way to know how much is putting out is to measure it with an ammeter and it depends on the load. If you are powering something that only requires 0.1 amp it will deliver only that. On the other hand if you try to power something that requires more than 3 amps (say a 24Volt 100 Watt light bulb which would require more than 4 amps)) it will current limit at 3 amps.
