Spark Electronics Rapid Speed [Matte White] Tapered Universal USB Power Adapter Wall Charger Compatible with Apple iPhone 7 7 Plus 6 6S Plus 5 s C Samsung Galaxy S7/S6 Edge Note Nokia … (3PC White)

One of them however after trying it when you plugged it into the socket (without anything in the USB slot) it would make a pop/twitch sound and then through the white block plastic you could see a spark inside of it. All of that went away when I finally plugged in a USB cable to the slot, but that seemed odd as if it would spark a fire or something!EDIT: I was charging my Amazon Fire Tablet with it and from the living room kept hearing the sound effect of it charging on then off then on then off. I went over to the unit and then a massive spark happened and black smoke came shooting out of the cube. The cube was blown and it shot soot all over the cable. Luckily it didn;t do anything to the cable or the tablet. But I switched to another cube in the pack and that one has been fine since. Maybe just 1 was a dud!

I needed some basic USB charger/power plugs for a few devices I had around the house. These were perfect!These are not the "quick charge" that you're expecting as the title says. This WILL charge your device just fine, but you're not going to get the fast-charge that you're use to. Your "quick charge" plugs are pushing out 2A of power while this is pushing out 1A. Nothing bad about that at all if all you need is a quick replacement.

I bought these along with some usb cords, I was not happy. After a few days when I would go to charge our phones they would go in and out, our phones would go on and off while charging. I tested it just to make sure it was the blocks with another one I had and sure enough it was these, won't buy again. I even messaged the seller, never heard back from them

Bought these just over a year ago and they have already stopped working. I was using them to power a simple led light strip. One of them actually overheated and cracked recently. I'm throwing them all out and getting new ones.Skip buying these or you'll be buying more in a year.

Works well. Never experienced a problem with these. Tight USB cable connection. Fits well in US standard outlets.

I can’t use these. One doesn’t even fit the USB chords and the other 2 get so hot in the outlet that they are a fire hazard. I have never had an issue like this with any other USB ports. I wasted my money. I hope this save someone else a few dollars.

May 2018: Two out of three work, one arrived DOA. Not worth returning.Update: the second one bit the dust in December 2018.

Amended: as soon as company found out they corrected the error immediately.Thank you so much for great customer service.Description states 3 PC's, but you only receive 1. I specifically ordered this because I needed 3. Waste of my money and no I don't have time to order again.
