This is a high-quality switching 'wall wart' AC to DC 5.1V 2,500mA USB Micro-B wall power supply manufactured specifically for projects that require a higher level of power. This compact USB AC charger is UL and CSA listed and incorporates a highly regulated output switching power design to assure a constant, accurate DC power delivery.
These wall adapters are perfect for supplying power to the Raspberry Pi 3's power requirements. Each adapter features a no-load voltage regulation within 3 percent of the rated output and works with 100-240VAC inputs.
If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.

I got a Matrix Voice board to go with my Raspberry Pi Zero. This adapter seemed not to provide enough current, because the Raspberry Pi kernel-segfaulted. That's a known failure mode if your adapter doesn't supply enough current. Other than that, it was fine running the Raspberry Pi Zero + camera + servo board + pan/tilt servos.
Purchased two of them for the two RPi3s I ordered. No complaints here. They can both be plugged in side-by-side and they run cool.
Powers the Raspberry Pi 3 with no issues
The wall adapter supplies power to the respberry pi 3 and the ssd and the 8 relay module just fine
I have a project that uses pi's with a small screen, an lcd, and a 64G thumb drive. Being new to the pi world, I assumed that that usb micro-b power socket meant I could use a phone charger power supply. I had measured the project current to be .8 amps with a usb current meter and since the charger power supply said it was rated 2.4 amps I figured i was good to go. wrong. The lcd flickered and the pi would hang and then get stuck in an fsck loop. Bought this supply and all problems disappeared. It's been running for a few weeks now without a glitch. I wish it had a usb socket instead of a cord because I wanted to use cables with 90 degree plugs. I had to buy an adapter. But that's my problem.
These power adapters are exactly as described. Very high quality.
Both adapters are doing the job I expected -- they not only power the fan, they also power the usb ports -- from what I can gather since using them on my cooling assemblies.
I see myself buying a couple more of these, to go with the couple more Raspberry Pi's in my future.
I was needing a higher amp output power supply for a Raspberry Pie project. It was at a good price and is working well.
The only thing I wish this power supply had was an On/Off switch. Besides that. Great!
How about adding an on-off switch?
I was using another manufacturer's power supply and was getting a constant low power warning from my Pi. I bought this guy and my Pi is chugging along perfectly, no matter what peripherals I'm using!
The extra voltage (5.1) and good regulation allow for distance at 1 or 2 amps. Good plan.
I used this power supply to power nightlight projects. It powers a circuit python microcontroller and a strip of dotstar leds.
Cuz' 1A just won't cut it.
Powers up the Raspberry Pi 3!
I bought these to support a Raspberry Pi 3B+ with 'Official' Raspberry Pi Touchscreen. Which, in theory, it should have supported. Ended up getting the Low Power Lightning Bolt on the touchscreen.
I ended up using two of them, one for the Touch Screen and one for the RPi3B+.
