[UL Listed] iUniker Raspberry Pi Power Supply with Switch 15W 5V 3A Micro USB Raspberry Pi 3 b+ Power Switch (UL Listed)

Got a DMR Hotspot for radio. It's a raspberry pi 3 B with a MMDVM duplex hat on it. Never had a raspberry pi. First thing I noticed was Undervoltage warnings. These were stopping me from using the dmr hotspot as services and hardware were being turned off or restarted constantly. I tried 2 mobile phone chargers, a macbook charger, a power strip with USB ports (which kind of worked) and a nice APC UPS with USB ports. All would get Undervoltage warnings. I was concerned about being a 3rd party power supply for my Pi, because well, you know, the recommendation is "an official 5.1V raspberry pi power supply", and this one clearly says 5.0v. I haven't seen an Undervoltage since plugging it in. It's working great, and I utterly love the on/off switch. Very nice.

I am using a Raspberry Pi with OctoPrint to control my 3D printer. Originally I was using a 2.5A adapter as it met the requirements for the Pi, but I kept getting low voltage alerts in OctoPrint. I started looking for a 3A adapter and found this item. I've been using it for a week and haven't gotten a single low voltage alert. It's also nice that this one has a built in power toggle so I can power down the Pi without needing to unplug it. Overall it's a great value for the money, it functions the way it's advertised, it's compatible with the Pi, and it appears to be good quality.

Makes it so much easier to turn off my mmdvm for HAM operations.great value, very durable and functional

I was trying to run my Raspberry Pi 24/7 as a little print server for my website orders, and a random phone charger kept giving me the dreaded undervoltage icon and occasional reboots. I switched to this official power supply and the problems disappeared immediately. The Pi now sits on my shelf, always on, and reliably triggers my auto-printing workflow. I’ll include a short video in my review showing it running the setup so you can see how solid it is. Voltage is rock-steady under load and the plug fits snugly—no wobble. It runs cool, doesn’t introduce any noise, and I’ve had zero brownouts since switching. Cable length is decent for a tidy setup, and it just looks and feels better built than the random chargers I tried. If you plan to leave a Pi on all day (especially with networking, a fan, or an external drive), save yourself the headaches and get the proper power supply. It’s the least exciting part of the build, but it’s the part that makes everything else “just work.”

so, it does what you need it to do. i liked that it is not a switched power supply, but a regular power supply with a switch attachment. having the option to run a pi without the switch if i dont need it.

Works as intended. Took care of the voltage warning on my raspberry pi 3b. I love the switch so I don’t have to unplug it every time after I shutdown.

I recently started using an old Raspberry Pi again but while it was in storage I got rid of pretty much all of my micro USB cables except two of them. I had tons of undervolt error messages, literally thousands per day showing up in my logs with the old cables. Since switching to this power supply I haven't had a single undervolt log. I also really like the inline switch so I can fully shut off the power without disconnecting from the outlet or from the Pi itself. Just makes sense, should've got one of these years ago.

Parfait pour le voyage et pas obliger de débrancher. Vive l'interrupteur
