HomeSpot5V 2.4A Power Supply/Adapter/Charger (UL Listed) with 5ft Long Micro USB Cable with On Off Switch Button for Raspberry Pi Arduino

I use a variety of microcontrollers (RPi, Arduino, BeagleBone, etc.), and generally speaking almost any 5V adapter is fine. However, in some cases (especially when I have to drive one or more relays), I need a bit more current capacity. I decided to try out these adapters to see if they'd work for me.Each adapter ships in a zip-lock bag, with a micro-USB cable, a small information card, and the adapter. The cord comes with an in-line switch, which is something I'd not seen before. It is handy for use with microcontrollers, as it allows you to power cycle the devices without having to unplug anything - HUGE plus. One of the main attractions of this particular adapter was that the power cable was not integrated. Some microcontrollers use mini-USB, so being able to avoid using an end adapter is a plus.As far as the adapter is concerned, it appears to be well made. The end cap flares out slightly, presumably to make it easier to unplug from an outlet. There are no obvious ergonomic problems with the design. The AC plug is not polarized, the profile of the adapter does not block the other plug of a standard 1-gang (2 outlet) or 2-gang (4 outlet) recepticle.I didn't analyze the power quality on my oscilliscope, but there's a reason... it's a small, basic switching power supply. I tried it out by pulling between 9 and 11 watts through it for several hours, and did not run into any instability. That's good enough for me, since I have bench power supplies for anything serious.Last notes: the product card indicates that the 12 month warranty automatically extends to 18 months if you register your product on their website. I didn't look at the terms of the warranty to see if the customer is responsible for shipping costs on replacements. I guess I don't really think of products like these as having warranties. Unlike many of these types of adapters, these are UL Listed (or at least are marked that way). I didn't look up the reference to see if it was legit, but that's easy enough to do.It's rare that I give anything 5 stars, but this seems worth it - especially if you can use the cord that comes with it. If your IoT application can run in a 2.4A (12W) or less power budget, you won't go wrong by getting this product. Highly recommended.

The AT Legends Gamer Pro connect to power via USB but ends up being "always on" unless I unplug the power or USB cable. I bought this so I would not have to continually unplug and plug in the cable to turn off the Legends Gamer Pro, and it works perfectly. I've been using it for over a month almost daily with no problems of any kind, and it is much more convenient for power cycling the unit.

My application is powering a six VFD tube clock, which requires +5V @ 500 ma, as measured by my bench power supply. After trying several of the USB chargers I had lying around I ordered QC 3.0 USB chargers rated at +5V 2.4A. All delivered only +3.5V when connected to the clock. My assumption is that their charging circuit was limiting the output. Eventually, I found this device. The description indicated that it was compatible with Raspberry Pi. It works perfectly with my clock, delivering the required +5V and no signs of over heating. This is such a handy little charger that I ordered two more for future projects.

Worked for my application with no problems.

Needed a power supply for a Raspberry Pi.This fits the bill perfectly.I no longer have to unplug the power cable from the Pi to power it down.I wish they also made a version of this with the power switch at the other end of the cable. I’d buy that version as well.

Used as power supply for a desk lamp

Worked exactly as described for my GRAN 3S Dart Board; no need for batteries, makes the dart board light up!

Originally bought for my Raspberry Pi Zero but needed a charger for an android phone so I decided to try it. It's suppose to be fast charging but it actually took a long time to charge. While plugged in, it barely charged the phone. I haven't used it yet for the Raspberry Pi Zero, but hoping it works better for it than it did a phone. I'll update this review if I have better results with the Pi.
