    • Best car charger I’ve owned.
Holds a MagSafe phone very well, charges quickly with the right plug. The vent adapter works well, too, but can pull off if your case has a magnet in it like mine. Otherwise no negatives. I prefer the adhesive mount which I think works the best, but my wife didn’t want the adhesive on her new cars dash. ... show more

    • Looks like great quality
I was pleasantly surprised when I opened this. It FEELS super sturdy, great quality and has a strong magnet. I will update this as times goes on, but so far I am pleased with the quality and it is exactly what I wanted.

    • Perfect magsafe car mount and charger
This is the best magsafe phone car mount and charger in my opinion. It ensures your phone will not overheat during charging and the magnet is strong enough to hold your phone in place while driving even through bumpy roads. I haven’t tried off roading but i have driven through a gravel road and my phone has not fallen off. This version is 7.5 watts and there is a 15 watts version but that costs three times more so i got this one because you get more value for your money. It is easy to install whether you use the adhesive stand and the vent stand. My wife wanted to try it so i installed it in her car and now she doesn’t want to give it back and i just bought another one haha. It is not heavy and fits most car vents as it fit both my car and my wife’s. The build seems sturdy and i don’t think it’s going to break anytime soon. I was worried the fan might be loud but i don’t seem to hear it even if i don’t play music in the car. I highly recommend this for people who don’t want to bother with setting up your phone and messing with wires every time you get in the car. It made my trips so much easier and convenient; i just place my phone on top of it, it snaps in place and charging starts right away. ... show more

    • Well made and easy to use but it didn't work for me. Not sure the "Cryoboost" benefit is real
I will start by letting you know what I have for equipment: Pixel 7 Pro, a Moment Magsafe case, and a OhSnap! 3.0 holding device (like a Magsafe compatible pop socket). I've told you all of that to tell you that I have not been able to get this device to consistently charge my phone and I really wanted this to work. I first tried it with the case alone . The phone snapped right into place and it indicated that it was charging but then it would indicate that it wasn't and this continued to happen intermittently, but with great regularity . Then I put the OhSnap device on the phone. It too snapped right into place and the same thing happened. I even went as far as to order another Halolock to see if it was just a faulty device...it wasn't, the same thing happened. I've since gotten a similar, but different device that works with my set up. I'm willing to give the ESR Halolock with Cryoboost the benefit of the doubt and say it just wasn't able to play well with my set up. This is a really nice charger. It's super sturdy. The magnets firmly connect it to the phone. The vent clip is the best I've ever used and easy to place. It's really well designed and holds the phone firmly in place. . The fan blowing is barely audible. While I'm talking about the fan, I'll say it's an interesting concept and was partly responsible for me buying it to begin with, but I'm not sure it has any real benefit. It doesn't seem strong enough to keep the phone from heating up. If it worked with my set up, I probably would have kept it despite my disbelief in the cooling effect. That said, I'm not at all disappointed that my new magnetic car charger doesn't have "cryoboost". Despite the fact that I couldn't get this to reliably charge my phone, I think due to some incompatibility between the Halolock and my Moment case, I would recommend it...which is saying a lot, all things considered! ... show more

    • Great magnetic wireless charger for iPhone 12 & 13
Review Image by Tech enthusiast

Review Image by Tech enthusiast
In the past couple of years, I have purchased several magnetic chargers for the car. They have ranged from cup holder ones, to vent Mount, windshield and CD player ones. The convenience of having the cell phone mount at almost eye level was extremely helpful and safe. This ESR magnetic halolock with cryoboost mount is a pleasure to use. The magnets on this paired with the iPhone magsafe is very sturdy. There is no shaking or slow slide of the phone off the mount (with potholes or rough pavement). The mount has blue led lights that illuminate and the numerous vents which emit air when the fan is active. It does not have a cooling or heating function. It circulates the air temperature within the car towards the rear of the phone. Assuming the climate control is utilized in the car to be comfortable (heat/ac) then that is what will be circulated through the mount. When the fan is active, you will hear it when parked and no sound (somewhat like a fly). It is not obtrusive but it is noticeable. It is a trade off in order to keep your phone from overheating or freezing (summer/winter). In a vehicle with no Apple CarPlay, this thing is a no brainer. For those with Apple CarPlay, you cannot charge it wireless. The iPHONE must be connected to the USB port for CarPlay to work (unless you have wireless CarPlay). Therefore, this will be more of a magnetic mount rather than a charger. Either way, my preference is to have the phone mounted rather than placed in an awkward location while it is connected to CarPlay. To sum up, it is great for cars with no Apple CarPlay or a front passenger to use for their own phone (ex. Road trip or heavy traffic). I can see this mounts potential if they had additional accessories such as a headrest attachment for back seat (kids in car) or to mount on a bicycle with a Velcro pouch to hold a portable charger. Compared to most cell phone accessories on Amazon, ESR has produced products that are of higher quality at reasonable prices. The iPhone case I am using is an ESR case with MagSafe. ... show more

The way this mounts is decent. I like the magnetic charging. It is not wireless charging as the description says.
