5V 3A Power Supply by MakerSpot with Switch 2.5A 2A 1.5A 1A Fast Charge AC Adapter w/ 1.5m Extra Long On Off Power Switch Micro USB Cable for Raspberry Pi 3 Model B/B+ Plus (4 Pack)

These chargers are very high quality and feel very solid. The AC wall plug snaps out firmly when opened and the micro USB fits snugly and is not even slightly loose. The in-line switch it came with is actually a push button switch and not a toggle like what's pictured, but it works great and I prefer it to the toggle. Raspberry Pis are very sensitive to loose connections and will loose power if the micro USB is even slightly worn and loose (unlike a cellphone), so it's great to have it always connected with the ability to power on with the push of a button.

I bought the four pack to replace some 2 and 2.5 am power supplies that were struggling to keep up. These bad boys are doing a commendable job of providing ample power for my needs. And the inline switch is just an added bonus.I can recommend these power supplies without reservation.UPDATE:The review above was give with only two of the power supplies in operation. The third also worked well, however, this morning I tried to put the fourth into service and it is completely dead. It has no power output whatsoever.Disappointing.I have reduced my 5-Star Rating to 3 stars.SECOND UPDATE: Customer service is outstanding!!I contacted the seller about the one dead power supply. They replaced it and when I got the email I checked the tracking number and the replacement is already in my mailbox. That was basically overnight!! Really, really excellent customer service.Bumped my review back to a full 5 Stars.

Bought a pack of these, with the intention to fix performance issues, as my "high powered" USB chargers for our phones could not keep up. These things are great. The Pi3B I have with a 10" touch screen, powered from the Pi, originally flashed the lightning bolt, and now ever does.The only issues I have:- These things are just wide enough, depending on the power strip, that I needed 3-6" power cable extenders. Otherwise I'd be using every other slot on the power strips.- I wish I could buy the chargers without the cables, or at least cables without power switches. With the exception of one of the four cables (I just needed a short cable), they were of no use to me.I plan to buy more soon, as these actually keep a consistent output.

I've been very pleased with these power supplies. It's difficult to find a USB power supply that can handle the amperage of most maker projects once you add a camera, fans, and other things like that to your pi. I also really like that there's a power switch, I'm a lot less worried about breaking the micro USB connector on my Pi's because I don't have to plug and unplug them every time that I use them. Thanks for making a great product!

If I could keep up with these they would be absolutely awesome... Every time I need one I can't find it that's my only problem they work good

I had it connected to an ESP32 DevKit 1 board and it failed after 3 days of continuous use. The power supply failed as I switched around cables and power supplies. I have another ESP32 that's been running 5 days withanother from the 4-pack. I'll post again in the future after it has run a while.

All work well and take up a single plug. This means all can be on the same inexpensive power strip. I looked for a USB hub that could reliably deliver 2.5amps on all ports at the same time. I’ve heard this exist but the few I’ve found are never in stock. I also looked at charging stations but none had more that 2 ports that could give a constant 2.5 amps. ...but I digress.This is great for my Pi server farm. I hope there will be a 3.0 Amp version for the Pi 4B+.

In a world ruled by inferior power supplies and cables, these are the legendary heroes. Don't run your raspberry pi without it.I have a Western Digital PiDrive, which includes cables specially made for a hard drive used with a raspberry pi. They are terrible cables and don't deliver even with a 4 amp source. these allow me to switch power to both devices and actually provide a decent amperage.

Great value, I purchased these for my older RPI's so I can utilize the physical power buttons.Provides more than enough power and the power buttons work great.
