AINOPE 4.8A Car Charger Adapter, Cigarette Lighter USB Car Charger

Finally a fast charger that is actually fast! Love the low profile and the double socket. Excellent purchase, highly recommend!

Just to be sure you know, box clearly states "WARNING: Warning: It does not support Qualcomm Quick Charge. The charging page will nor [sic] show fast charge when charging" I didn't need that functionality, so no matter to me ... but maybe it matters to you. If you need a charge faster than this device provides ... and you need to charge so often ... maybe you ought ramp-down on your device usage ... or keep an external battery at-the-ready. I've got a small thin one, no larger than the phone, in the glove box ... and it can give me 2.5 full phone charges while connected to the phone, both in my pocket. This gizmo is solid construction. In my vehicle, yes, it is almost entirely flush with the cigarette lighter and snugs-up into it tight. I really like the soft blue glow of it. This blue ought be the default LED power color for all technology devices, it so easy on the eyes. And, in my vehicle, it does NOT glow blue when the power is off. And I see that as a GOOD thing. Any drain on an idle vehicle's battery is a bad drain, no matter how small. I know -- from experience -- that even a small LED pulling on the battery of a parked vehicle overnight can drain its battery to stone cold dead. Yet the maker reports that, in some cars, the LED in this device might stay lit and pull power. Accordingly, the maker should re-think construction to not allow it to do so. Notice that the USB slots are oriented opposite one another. A USB that goes straight-into the top socket will have to be turned 180 to go into the bottom socket. I've NEVER seen dual USB sockets oriented like this … and it may be bothersome to some users who are used to always finding any female USB socket oriented the same way. I suppose the maker was thinking that, oriented as they are, there will not be a top or bottom to this gizmo, that no matter which way you install it into the cigarette lighter socket, the two USB sockets will always orient the same way. That might be a bit of overthinking going on there. There is clear plastic shrink-wrap protecting the charger when you get it. That you have to remove to use it, to make metal-to-metal connection for it to get power. And I will tell you that shrink-wrap is on there tighter than a coat of paint. There is no perforation or tab to help pull it off. I had to find a good location to prick-it with a single-edge razor blade … to get a starting point … to put a small pin under it … to pull on it to get enough plastic to make a tab to pull the rest of it off. I appreciate the meticulous level of detail in the build of this product … everywhere except in this plastic shrink-wrap. The maker should re-think this a bit more in future production.

2022 UPDATE: Just ordered another one for an additional vehicle. These units work very well at "rapid charge" for Samsung S20 and IPhone 13. (earlier UPDATE:) The replacement works very well! I have received a replacement, no charge from the vendor of this product after a baffling series of problems with the previous example. Both the Galaxy 7 and the Galaxy 10 show "fast charge" with their two respective cables attached and this unit plugged into an "always on" accessory receptacle in our truck. Rapid charge was completed in about the time the screen estimated on both. Charging two phones at the rapid rate probably comes close to the rated capacity of this unit. But, the charging plug barely got warm, which tells me there's a good margin of safety. The metal housing of this charger helps disappate what little heat is normally generated. I have since charged just one or the other of the two Galaxies, and there is no difference in charging "time" estmated. This tells me the charging unit is well regulated and capable of its full, safely-throttled power to avoid damaging the smartphone. I would have been concerned if the charging time displayed had changed significantly. A reduction in that time would suggest the charger was delivering higher current (for good or bad) than when both phones were charging. A significant increase in that time would suggest poor regulation with one phone, and marginal capacity if the time were prolonged when trying to charge both phones. Another positive discovery: This charger does NOT cause interference in my car radio !!! I have another brand, the Skyocean QC 3.0, that generates an audible hash on AM broadcast stations I try to listen to. It also causes enough interference on FM that stations cut out a lot more often when their model is plugged in and I'm driving along. NO such problem with the Ainope. Recommended product. --- initial review follows --- There might be a problem using this product for rapid charge with the Samsung Galaxy, models S-7 and S-10. I am prepared to upgrade my rating of this device after testing a second one that's on its way. The initial example had an intermittent problem achieving rapid charge, which is the main reason I bought it. This unit is supposedly capable of both charging protocols , Qualcomm 2.0 and 3.0. The technical differences are available in an internet search, but for this review, just say the older 2.0 standard might be difficult for this unit to deliver. I have two Samsung Galaxy smartphones. Both are "Android," the superior system over Apple in offering a refined fast charge system. The Galaxy S7 is Qualcomm (QC) 2.0, and the Galaxy S10 is 3.0. At first I thought perhaps the cable was to blame for being able to get only the regular-rate of charge on the S7 from this product. But I tried the same cable on a different brand of car charger that had previously worked, and indeed, the screen told me a rapid charge was underway. I also tested the S10, which uses the newer type "C" connector. on its charging cable. Here, the first time I tried it, this product successfully delivered a rapid charge, but on subsequent attempts, I could get only "regular" rate charge. This suggested the unit, not my cables, was to blame. The vendor may have initially used a talking points script (their checklist to tell people, regardless of report) to make sure I was aware of cable shortcomings, when I already had told them my sequence of testing above. Eventually they directly discussed my concerns and suggestions. I had learned from a technical source that there are counterfeit chips among many brands of chargers that can imitate some, but not all, of the Qualcomm features, one of which is the backward compatibility of the present-day "3.0" to the older "2.0." But the Galaxy S7 has sold more than 55 million examples since 2016, according to published figures, and I told the vendor of this charger that I would be surprised if I was the first one to notice a problem if a batch of bogus chips had made it to their production line. So, they are considering my initial purchase a possible defect, and are sending another. (Twice they ignored my question about the possibility of bogus chips in their production run.) Will update this review.

I like the plug and that I have 2 spots to plug chargers into. HOWEVER, this does not fast charge like it says. It's not slow charging so I'll take it, but I bought it specifically for it being for fast charging.

So far, so good. Much quicker charge than I was getting off my old,outdated USB ports. Looks well constructed & fits nice & flush into the lighter assembly. Paired it with a new USB to USB C Cable for hi speed/quick charge & together they keep my phone charged well.

Works perfectly

Great little car charger. QC on both ports work great, charges our two Samsung S20 ultras at the same time. The body's not plastic but metal, which has got to be good for cooling; it does not seem to run hot. BUT when you take it out of the box and blow-mold carrier notice that it's in shrink wrap - and there's no way for the side contacts to work with that in place. I found myself wondering how many people tried to use it with the shrink wrap on - especially as there's nothing obvious indicating that it should be removed. I'm ordering a second one of these to keep with my for-rental-cars setup.

Great product competitive price.

Very good built quality and fits the lighter plug without ugly protrusion
