Review on High-Speed Dual Port Car Charger for iPhone, Samsung Galaxy, LG, iPad, GPS - [2Pack] 3.4A Fast Charge Cargador Carro Lighter Adapter by Joseph Campbell

Arrived fairly quickly, seemed a strong product. But if you think about it, you can tell by the color of the USB connectors that this isn't a 3.4 amp product. Nowhere does it actually show 3.4 amps charging at the plug for your cable. In any case, they seemed sturdy enough to try on. I've been trying them for a few days now. And they don't work! They hardly charge any device connected to them! I need to plug in the phone, turn it off. And in an hour, only 5-10% is charged. That makes it a bit slower than even a cheap charger. that's the 1 amp I have in my car as a backup! and this product doesn't help so much that I wanted to throw them out the window while driving as they feel like they are draining your phone instead of charging devices. But I knew I could get a refund! And that's why I didn't throw it. They don't exist yet. I was trying to get my money back thinking it could just be two bad products and not the product as a whole. And Revain or the seller will not even allow you to issue a refund to the seller! So I officially threw them away and will keep trying to get a refund because now it cost me way more money to get them done on time than it cost money!
