Review on AINOPE USB Car Charger: Dual QC3.0 Port Fast Car Charger Adapter with All Metal Construction - Quick Charge Compatible with iPhone 11 pro/11/ x/8, Note 9/Galaxy S10/S9 by Scott Gamache

UPDATE: Replacement works very well! I received a free replacement from the supplier of this product after a series of inexplicable problems with the previous example. Both the Galaxy 7 and Galaxy 10 show up as "Fast Charge" with two matching cables attached, and this device is plugged into the "always on" accessory jack in our truck. The quick charge was completed in about the time shown on the screen of both. Charging two phones at high speed is probably close to this device's rated capacity. But the charging plug barely got warm, which gives me a good margin of safety. The metal casing of this charger helps to dissipate the small amount of heat that is normally generated. Since then I have only charged one or the other of the two galaxies and there is no difference in the charging time estimate. This tells me that the charger is well regulated and able to work at full, safely regulated power so as not to damage the smartphone. I would be concerned if the displayed load time changed significantly. Decreasing this time means the charger will put out a higher current (for better or for worse) than if both phones were charging. A significant increase in this time indicates poor regulation with one phone and limited capacity when the time increases trying to charge both phones. Another positive discovery: this charger does NOT interfere with my car radio! I have another brand, Skyocean QC 3.0, that produces an audible hash on AM broadcast stations that I'm trying to listen to. It also causes enough interference on FM that stations cut off a lot more often when their model is on and I'm driving. There is NO such problem with Ainope. Recommended product. --- First review to come --- There may be a problem using this fast charging product with Samsung Galaxy S-7 and S-10 models. I'm ready to update my review of this device after testing the second one that's on the way. In the first example, there was an intermittent problem with fast charging, which was the main reason for the purchase. This device is said to support both Qualcomm 2.0 and 3.0 charging protocols. The technical differences are available by searching the web, but for this test we'll just say that the old 2.0 standard might be difficult for this device. I have two Samsung Galaxy smartphones. Both are superior to Apple's "Android" system and offer an advanced fast charging system. The Galaxy S7 is Qualcomm (QC) 2.0 while the Galaxy S10 is 3.0. At first I thought that maybe the cable is to blame for the fact that I was only able to get the usual charging speed on the S7 with this product. But I tried the same cable on a different brand of car charger that worked previously and sure enough the screen showed me that a fast charge was in progress. I also tested the S10, which uses the newer Type-C connector. on the charging cable. Here, when I tried it for the first time, this product successfully charged fast, but on later attempts, I was only able to charge "normal". That suggests the device is to blame, not my cables. The vendor may have originally used a discussion script (their checklist to inform people independently of the report) to ensure I'm aware of the cable's shortcomings, although I've already told them about my test sequence above. In the end, they responded directly to my concerns and suggestions. I learned from a tech source that among many brands of chargers there are fake chips that can mimic some but not all Qualcomm features, one of which is backwards compatibility of the real one. -day"3.0" to the old "2.0". But according to published data, the Galaxy S7 has sold more than 55 million units since 2016, and I told the seller of this charger that I would be surprised if I was the first to notice the problem if a batch of counterfeit chips were made. it to your production line. So they consider my original purchase a possible defect and send another one. (Twice they ignored my question about the possibility of counterfeit chips in their production cycle.) Will update this review.
