The importance of power for Raspberry Pi The power of the Raspberry Pi is the top priority. No matter how many peripherals you have, it is best to send the full 5V 3A power to the Raspberry. This is the experience gained by the Raspberry Pi after more than a year or two of actual combat. Otherwise, Your mouse and keyboard may not move or be stuck, and secondly, the display may not display or "fluctuate". It will not be stable when used. This product is designed for the Raspberry Pi to eliminate such problems. Power suffer provide stable and enough current This power adapter differs from typical standard 5V USB power supplies in the market in that it can deliver a full 3A and still output a voltage well within the USB minimum voltage specifications.Maximize protect your Raspberry Pi . Standard 5V USB power supplies in the market have a high voltage drop when the full current is drawn from them which may cause the Raspberry Pi to reboot unexpectedly. Come with a ON/OFF switch Come with a switch for quickly and easily control of the Raspberry Pi without plugging and unplugging the charging cable. Elegant design for your Raspberry Pi Ergonomically designed, edge-polished, sleek, streamlined design for a comfortable feel, high flame-retardant PC. Note: Compatible with Raspberry Pi 4 only. Not compatible with Raspberry Pi 3 B, B+, A+ or Pi Zero. Specification: ● Input: AC 110-240V, 50-60Hz ● Output: DC 5.1V / 3.0A ● Charger cord Length: 3ft ● Plug: US Package： 1*USB C power supply

Workable for some Pi 4 uses but know what you're getting
It's a pity as I like the switch but facts are facts. This power supply may be fine for Pi 4s that aren't using beefy USB attachments, but it doesn't measure up to the claimed specs. When I tested this power supply with an electronic load the voltage varied quite a bit. At the typical Pi 4 idling current (0.7 A) the output was 5.2 V, which is fine as far as it goes. Simulate the significant peripheral draw from a USB attachment at 2.0 A, however, and the voltage has dropped to 4.9 V. At the full rated spec of 3.0 A the output had drooped down to 4.7 V.Now this power supply is far from the only one to not measure up to specs. And the Pi 4 has its own on-board voltage regulation, so for users who only attach a keyboard, mouse, and display this supply should be fine. But if I were attaching an SSD (often rated 1.5-1.7 A) and other things, I'd be thinking about using a powered hub -- which sort of defeats the low cost advantage of this product and others like it. From my testing the supplies from Canakit and Berls offer superior regulation at higher currents and aren't much more expensive. I also have one of those supplies using a small, round power switch and I was pleasantly surprised to find its output rock steady all the way to 2.8 A.

Does what is says BUT the cord is very short!
It powers my PI but the cord is only 3 feet! I was lucky that I use it but most people will need a longer cord. Make sure you can get away with only 3 feet.
