Review: Impeccable - It looks and works exactly as described. It is somewhat more voluminous than the original Raspberry Pi source because it is more powerful. Quality looks very good. No more “low voltage” messages. 😃
Review: No more undervoltage warnings on my Pi - I picked this up to power a Raspberry Pi in a small project after getting tired of random undervoltage warnings from whatever charger happened to be in the drawer. Several months in, it has run cool and stable with no low voltage complaints, even with a drive and a couple of accessories hanging off the board. It feels like a properly built supply rather than a generic brick, and I like knowing it is UL listed for something that stays plugged in around the clock. My only note is the cable. It is a little short, so where the project sits relative to the outlet matters, and I ended up moving mine to a closer plug. Not a deal breaker, just something to measure first. If you are running a Pi or a similar board, this has been the reliable option for me.

## Questions & Answers

**Q: How to Test the PSU Output correctly?**
A: Please refer to our test video: youtu.be/leqeFTJcSHk; the test method by Noah Ferro is not right test method, it need to add load to test the power supply output ability.

**Q: Does this power supply support fast charging?**
A: No. This is a standard Type-C 5V 4A power adapter and does not support fast charging protocols.
