Enokay Power Supply for Raspberry Pi 2 3 Micro USB Charger Adapter with On Off Switch (5V 3.0A)

I ordered two of these. The first one had an intermittent USB connection which was very disappointing. Luckily I had order two. The second one worked great. I had no trouble returning the first one. I will probably order another one.I ordered this for the power adapter and really wasn't interested in the cable, although the cable works fine too. I planned to use them to replace some failed D-Link 5V adapters, one 2A and one 2.5A. Since this adapter was capable of 3A, it had enough capacity to replace the failed adapters. To make this work with my D-Link products, I ordered some USB cables with a barrel connector of the proper size on the other end. I could have order a replacement adapter with attached cable, but I preferred the USB connection over a fixed cable that could fail and render the adapter useless. The adapter also exceeds the capacity needed to charge my iPad, iPhone, Bluetooth speakers & headphones; so it becomes very versatile that way with the right cable.I knocked it down a star because of the one adapter that was bad. I was going to rate it 3 stars because of that, but since I will probably be ordering some more, that low rating didn't make sense.

Purchased this product to power a Raspberry Pi 3B+. Even during boot, the Pi starts reporting that this power supply isn't providing sufficient power. And thats even with a headless Pi with no keyboard nor mouse connected.I haven't noticed the Pi crashing or rebooting yet, but its disconcerting that the Pi is reporting low voltage. I have a power supply converted on my 3d printer that does supply steady power, so I know its not the Pi misrepresenting voltage.FYI: the red light on the Raspberry Pi 3B+ is supposed to stay on. It goes off when the input voltage drops below 4.63 volts.Its been reported that the headless Pi can boot on less than 1 amp. That makes the advertised 3A output of this device very questionable.

Purchased this for a Pi3B+ and I'm getting an under-power error. This product originally said 3amps and the description has since changed to 2.5amps. Even 2.5 should be enough for a Pi3b+ without peripherals, but this isn't powering it. Unreliable specs on the product.

The power supply does work effectively however I use it to power my Raspberry Pi 3 and I still intermittently get the low voltage indicator on the screen. This means this power supply cannot maintain 5 volts, even at 3 amps. It doesn't do it very often, but that's the reason why I got a 3 amp power supply... I'll keep looking.

I bought the 3.0A version thinking it would be enough to power my Raspberry Pi (if it was actually rated 3.0 A, it would have no issue). It ran for a few minutes, and now I can no longer boot the Pi without a lightning bolt error due to insufficient power. My other power adapters work fine. This is garbage.

I bought this product for a Raspberry Pi 3B (not the plus), which recommends a 2.5A PSU. I figured that this adapter would work great but after a few weeks, I started to receive the lightning bolt symbol in the corner of my Raspberry Pi. I feel that I can no longer trust the reliability of this product.

Cable works great. Powerblock outputs 4.8v instead of 5. Will not work well with Raspberry Pi and as such is useless to me. Spend more and get a better quality block.

Great for a retro pie since it doesn't have an on/off switch.
