These have USB plastered everywhere.... But they have no USB ends. Unless I dont understand what USB means. But these blocks have a female C type plug and the cords have C type male ends on both sides.

Thye work very well!

Much faster than previous chargers!

10ft cords and fast charger does great job.

At first, I was worried that it would create a warmth with the phone, but it did not. It worked really well and fast.

Works really good on my Samsung s20. It charges really fast

Although I broke one of them a while back, the second one has held up for a very long time. I will say I mostly keep it in my room and it rarely leaves which could be a factor to its longevity, but nonetheless it does its job and still continues to Super Fast Charge even with repeated use. Overall a good choice for a charger.

I dont have alot to say about this product because it does what it says its going to do - charges your phone REALLY fast! Have had it for a couple of months or so, and the 2 pack was great for being able to keep them in different spots rather than constantly move a singular one around. The best thing was that this charger actually charged my laptop too, which no other fast charger Ive gotten has been able to do. If youre like me, youll be shocked at just how little time charging your phone will take with these little devices! Also, the cords are super long which is a life-saver when the only outlet available is all the way across the room

I wasnt sure these would work out well. I was happy to be proven wrong. Great value!

Works so very fast to charge my samsung s22+ phone. Love it!
