## Questions & Answers

**Q: Will it test 100w and above, preferably looking for a 150w but 100w would be fine.**
A: Rating is Input 3VDC - 20VDC  and 0A - 3A so it will not test to 100W

**Q: The description says this unit will test "most" usb-c ports. i need to test usb-c 3.1 gen 2 and thunderbolt 3.  are these covered by the et920?**
A: It tests usb under load so with a converter it should test the voltage and amperage.
