Review on Mongoora Metal Car Charger Adapter - Fast Dual USB Ports, Portable 3.0 Car Chargers for iPhone & Android Devices by Carlos Massey

Pros: This is indeed a "fast charger" and I used the same block in the photo to measure over 9vdc on a Samsung phone and tablet. He had no problem with a large tablet in the car in the sun. Both phone and tablet displayed "Fast Charge". Even with an older tablet charged with 5V DC it worked perfectly and kept the device at 100% in bright light. The device did not heat up during operation. The blue light is spot on, faint but visible at night, not uncomfortable at all. Cons: The device failed 2 days before the return window closed. As you can see from the photo, it had some voltage but didn't pass any current. I think the USB charging is actually controlled by the battery in the device being charged, so I think the chip that communicates with the battery has failed because the battery is asking for power but the charger isn't hearing it. Plugged in another reliable charger, the tablet turned on immediately using the same cable. I also didn't really like the small overall length of the device. On the plus side it stays in the socket VERY well and it has very strong springs inside so nothing can come loose but with the design it takes all your clamping force and then some to pull the charger out. Interconnects. I can do this after eating some spinach, but you're wondering. Why? Overall, reviews seem pretty good, although there are occasional dips. I would definitely keep it if it holds up, but this one was getting a little dusty and the issue of removing it while still being compact bothered me. I'm switching to another brand. The return process, on the other hand, was absolutely brilliant, I decided to send it to a UPS store by simply scanning the barcode. They pack and ship and give you a receipt. I was out there in less than a minute. Incredible support, Revane!
