NorthPada Raspberry Pi 3 Model B+ A+ Plus Power Supply Charger AC Adapter Cord 5V 3A PSU Micro USB 5 Feet with Power On/Off Switch, with a USB C Adapter for Raspberry Pi 4 Model B, Pi 400

I have been contending with low voltage indications on the RASPI 3B+ for a long time. Tried many solutions, various 110 to 5 volt supplies, buck power supply 12 to 5 V 5A and variable supply. Feeding through the connector and directly to the GPIO 5V pin. Nothing worked until I tried this supply. It works great. No lightning bolt, or low voltage warning. I was sceptical with all that had been tired before but this works and let's me know the issue is voltage related and not a bad pi. So now the goal is to power it from a 12 volt battery to 5 V and complete my weather station.

A good power supply for the Raspberry Pi 3. I use mine with a Raspberry Pi to play videos, and I've never had any issues with freezing / crashing under high load, suggesting the supply is stable.On / Off button is handy, means you don't have to unplug anything to reset if needed.

I purchased a couple of these NORTHPADA power supplies with built-in switches, to power a bluetooth transmitter and receiver pair I use for my outdoor audio system. The bluetooth devices have their own power buttons, but they're "push and hold"-types that don't have a positive feel, and there are no indicator lights on them, to confirm "on/off" status. These power supplies terminate in micro USB connectors- exactly what my devices use, provide 5-volt, 3-amp outputs- so my devices don't starve for power, and the built-in "on/off" button not only positively "snaps", but also features a red LED indicator to definitively indicate status. It's worth pointing out that the power buttons on these supplies are most convenient, when the device you're using them with will remain switched on, if the power to the device is cut. Otherwise, you'll find yourself turning on the power supply, and then turning on the device, too. Overall, these supplies are great. I've had mine plugged in for months now, and they're still going strong.

En mi necesidad de poder alimentar mi raspberry pi 3B+, no encontraba un adaptador que me diera esa potencia que me da este, muy buen articulo

I could not find a suitable Pwr Sup for my Pi 3 and then I bought this one. No more lightening bolt flashing at me. It works great, but minus 1 start for the switch. The switch is fine and has a nice thick membrane over it that it not going to wear out, but …. it is a little to thick and the switch gets stuck turning it on and off. A little wiggle and it pops back to position, but not something you want to be futzing with when it comes to Pi pwr. Else it is a great product I I won’t use the switch much anyhow so I’ll keep it with only 4 stars.

Works great for my raspberry pi 3 b +. I'm using this to power the pi, which is being used as an arcade setup. This adapter powers the raspberry pi, which in turn powers two sets of arcade-player controls connected to the pi via USB, and does this all adequately. I no longer ever see the low power indicator in the upper right screen or in text at boot up.As a bonus (and I haven't seen any other review mention it or the product description mention it also) but my adapter also came with a full metal body for the top and underside of the pi 3 b+ with built in fans and thermal adhesive for joining the chips with the metal body for emissivity! This was an excellent bonus, and at this price combined with the adapter, I kinda wondered if they accidentally added these extras to my adapter order.....

I recently bought a Raspberry Pi 3 to build a Retropie machine, but the cable that came with the case was not adequate as I kept seeing the undervoltage sign (lightning bolt). So I tried using a fast charging cable for my LG phone which is rated at 5V 2A. It was better, but the undervoltage sign still showed up occasionally. I finally gave up and decided to buy this cable after much deliberation.And boy, am I glad I did! Ever since connecting this power supply, I have not seen a single undervoltage sign. I played for several hours in one sitting at one time and this power supply kept my Raspberry Pi 3 at full speed. Did I mention I have overclocked my Raspberry Pi 3?My Retropie setup has a powered fan, USB hub connected with two controllers, wireless keyboard USB dongle all connected at the same time and overclocked to 1300 MHz to boot, and this power supply was able to provide enough juice for everything. It also has a switch for easy power down! I highly recommend this power supply to anyone having a undervoltage problem. In my opinion, it's a must have if you overclock your Raspberry Pi 3.

Why do I get undervoltage warnings on my Pi? People told me the power supplies may have been bad, so I tried the "official" adapter and Canakit's, and a couple other 2.5A adapters. All of them I still give me undervoltage warnings.People said maybe it's the cable's fault. But these are brand new, and I never add anything "additional" to the USB cables, either, they just plug directly into the Pi. People told me maybe it's the power outlet itself, but I've not only tried different outlets, but I've tried different buildings! And the same thing.People told me maybe my Pi was faulty. But I have had this problem on the Pi 1, 2, 3, and 4! People said maybe I'm drawing too much power from the Pi. What could be drawing too much power? My keyboard? If the Pi can't power a USB keyboard then all Pis must be faulty, not just mine.I've come to the conclusion the Raspberry Pi Foundation is faulty. 2.5A is just not enough. I finally decided to try a 3.0A supply and guess what? No more undervoltage warnings.I will recommend 3.0A power supplies to anyone over the "official" one or Canakit's. It just works, finally. And having a button built-in to the cable is very convenient. It will make sure I don't wear out the port from unplugging and plugging it back in over and over again.I am happy to finally have something that works after putting up with these annoying warnings for years.

Get's the job done

Worked great for 1 week then died lol I tried it like 5btimes and nothing and now all of a sudden it started working again and works great ,,, so IDK WTF its great now that its working again , and if used to charge my phone, its really fast

When using my Raspberry Pi 3b+ I kept getting "lightning bolt" icon on the upright corner of the screen, meaning not enough power. I tried different power supplies, without success -- even another one that claimed to be 3A. This power supply seems to work well and deliver the required Amps. No more lightning bolts and my Raspberry Pi is running smoother now. The little power-button is so helpful, so I don't have to bother plugging and unplugging the power. Just use the button.

No power under voltage alerts and performance issues noticed with this power supply.

Works fine for my RPi 3b+
