It works
I bought this to power an LED matrix that requires 5V 10A, it easily powers the leds and the pi zero that I am using in the project, it does have an led on the power brick that is a bright blue

Good Product, Slow Delivery
The product was great. The delivery was below average. The tracking showed it sat somewhere in Los Angeles for a night and part of a day with NO tracking, so we thought it had been lost and ordered a backup product.

It even came with adapters
Although not listed in the description, mine came with a bag of 3 adapters; micro USB, USB-C and a different size barrel adapter. This makes connecting to a Raspberry PI 3 or 4 really easy. Because of my case for the PI I had to trim off a portion of the adapter molding but the molding was beefy enough to not cause a problem. My original PI with the factory power supply was flashing the yellow lightning bolt and occasionally rebooting itself. This power supply seems to have solved this problem and if not I'll be able to use it on another SBC.

Perfect for the Raspberry Pi 3/4 combined with NAS enclosures
I was using the Geekworm x820 hardware with the Raspberry Pi 3B, and the included AC adapter wasn't providing a consistent voltage. The "Low Voltage" warning kept filling my log files while using that low quality adapter. The LeTaoXing 5V 4A Adapter fixed that issue. Thanks!

Works well, voltage at about 5.25V with or without load
Works as expected. The cord is a we bit short. Would like it to be closer to 6 feet. But it does what is required.

Not compatible with jetson nano
Does not work on Jetson nano. The Barrel jack is to small.

Matrix approved
Purchased for powering a 64x64 rgb led matrix and a rapsberry pi 3b+. Absolutely silent, seems to have no issues with powering it.

Terrible. Doesn't do anything right.
Bought this hoping it would be better than the others out there. It is not. I didn't doubt it would deliver 10A without catching on fire. With a 3A load I could smell burning and the connector was almost too hot to hold. This overshadowed the fact that it started out at 5.6V and as soon as I put a half amp load that dipped to 4.9V. as I increased the load to 3A voltage dropped into the 3.5V range. So so bad! I bought a Meanwell supply and it is rock steady. Will be returning this. Hopefully it doesn't start a fire in transit.
