  • Package includes charger and USB cable

The initial excitement that comes with unboxing a new gadget is always an essential part of the user experience, and this wireless car charger? It delivers!

Taking a Closer Look at The Product Packaging

The packaging used for the Halo Lock Wireless Car Charger immediately caught my attention. Terms like “eye-catching” and “impressive” barely do it justice. The product information detailed on the back of the box is useful, providing a preview of the item’s capabilities and features, particularly its power output: 5 watts and 7.5 watts.

The moment I unboxed the car charger, I was greeted with a well-crafted presentation. It was beautiful and extraordinary enough to rival that of major tech giants. The packaging was elegant and tidy, with each piece meticulously secured in its place. It was an attractive feast for the eyes which exuded a very professional aura.

Initial Impressions: The Charger’s Intricate Design and Build

Extricating the wireless car charger from its impressive housing, the design is immediately striking. It has vents round the edge enhancing its aesthetic and presumably functional too.

As a bonus, a USB A to C cable is included in the package with the charger along with an easy-to-install clamp. The presence of these additional items was definitely a plus, as it meant no immediate need to purchase any additional accessories.

After getting over the initial awe of unboxing, I did a quick scan of the clear and easy-to-follow instructions. It was time to put this device to the test and see if its performance was as good as its presentation.

Detailed Examination

  • Charger well-designed with thoughtfully placed vents
  • USB-C port initiates main charger operation
  • Charger fan effectively combats heat issues

Time to delve deeper into the product and sort through the details. Unveiling the charger, it came across as a well-designed device. The design appeared thoughtful, with vents carefully placed all around. A particularly interesting feature was the USB-C port that initiates the charger’s main operation.

The Experience of Plugging in the Charger

Without wasting any time, I decided to plug in the charger. The immediate kick-start of the fan was noticeable. Not just audible, you could actually feel the cool air being circulated. It certainly lived up to the marketed tagline of combating heat issues related to wireless charging.

Charger’s Claim to Fame – Can It Really Eliminate Heat?

Now onto the main question – does the product perform as it promises? The claim is big, that the charger solves the heat problem associated with wireless charging. After plugging in the charger, I could indeed sense the cold air being blown out. The claims didn’t seem inflated as the charger did feel cold upon contact.

Dissecting the Product

  1. Design: The design needs a special mention as it seemed well-thought-out. Despite being packed with features, the charger didn’t come off as bulky or inappropriate for a car setup.
  2. Functionality: Its main operation – charging, seemed fine. The added cooling feature was innovative and necessary given the heat issue wireless chargers face.
  3. Quality: The build quality seemed sturdy and solid. No loose ends or flimsy parts were observed.

However, as I started to weigh its performance, a couple of questions crossed my mind. Does it solve the heat issue or is it merely a fan blowing air? Is it truly an innovation or an addition of an already existing technology? These were the aspects that required further scrutiny.

The Practical Usage

  • ESR Halo Lock offers effective cooling during charging
  • It enables convenient and unobstructed mobile usage
  • Design is sleek, minimalist with sturdy clamp

In theory, this wireless car charger seems to be a smart solution for maintaining your phone’s battery life, particularly during those long drives. With its highly lauded cooling technology, I was deeply intrigued to test out its viability in a real car setting.

Charging the iPhone 14 Pro

The moment of truth came when I hooked up my caseless iPhone 14 Pro to the ESR Halo Lock. The charger instantly got to work. A soft whir signaled the start of the cooling process, with a cool breeze circulating around the phone, possibly a testament to its cryoboost technology. I was taken aback initially, as the device became noticeably chilled to the touch, almost immediately.

As expected, the charger was easily able to power up the device without the MagSafe logo popping up, implying a wireless charge of about 7.5 watts, not the full 15 watts MagSafe capability. While the fan came to an immediate halt upon removing the device, the cold touch lingered, especially around the grip area. Just as quickly though, the fan resumed its cooling manoeuvres the moment the phone was reattached, demonstrating a swift response rate to the device’s heating changes.

Analyzing The Pros: Convenient, Functional, and Effective Cooling

Functionally, the ESR Halo Lock performed soundly. It was able to continuously offer a refreshing stream of cool air, effectively mitigating any implications of heat while charging. The convenience was undeniable. Even whilst driving, access to maps and other essential utilities was easy and unobstructed.

Design-wise, this wireless charger definitely hit some high notes. Its sleek, minimalist layout punctuated with ambient lights gives it a touch of sophistication. The sturdy clamp, in particular, made way for a seamless attachment onto the car vent and had a strong grip that held the device securely in place.

Undeniably though, the biggest win for me was the true-to-claim cooling functionality. After several instances of use, it indeed kept the phone’s temperature in check, making it an effective solution to combating heating issues during wireless charging.

Potential Drawbacks

  • Charger’s cooling technology might cause condensation
  • Fast charge doesn’t exactly equate to MagSafe charge

Although the ESR Halo Lock Wireless Car Charger with CryoBoost displays a number of impressive features, there are a couple of potential hitches that caught my attention while using this product.

Questioning the Design: Risk of Condensation Due to Cooling?

In my experience, technological devices and water don’t exactly mix. Now, this charger employs active cooling technology to keep your phone cold while it charges. While using it, the rampant question in my mind was about the potential formation of condensation due to the hot and cold air exchange. Considering the cool air it blows around the phone, one could speculate this might lead to moisture build-up, which could potentially harm the internals of the phone. Now, it’s not certain, but a potential drawback to consider.

Dissecting the Claims: Can This Charge Faster Than A MagSafe Charger?

The ESR Halo Lock Wireless Car Charger claims to charge faster than any other MagSafe charger. However, upon using it, I found this claim to be slightly confusing. The maximum output of this wireless car charger is 7.5 watts, whereas Apple’s MagSafe outputs 15 watts – that’s twice the speed. The box indicates that it can charge faster than other MagSafe chargers only because the phone might throttle the charge when it overheats. But, in reality, the car charger is not MagSafe compatible itself. Meaning, it doesn’t display the MagSafe logo when connected. Hence, fast charge doesn’t exactly equate to MagSafe charge . Personally, it feels like the marketing might not be in line with the actual experiences.

In conclusion, while the ESR Halo Lock is quite an innovative wireless car charger and possesses some truly unique features, it comes with couple of potential drawbacks. It would be useful for potential buyers to be informed about such details so they can make a fair and well-considered purchase decision.

Verdict: ESR HaloLock Wireless Car Charger with CryoBoost + ESR HaloLock 3-in-1 Wireless Charger with CryoBoost


So there you have it – a thorough look at the ESR’s Halo Lock Wireless Car Charger with CryoBoost. This review was both exhilarating and enlightening, allowing me to delve into the unique features this charger brings to the market, notably the CryoBoost technology intended to overcome the perpetual problem of phone overheating while wireless charging.

My Final Thoughts

The ESR Halo Lock Wireless Car Charger aims to solve an issue all too familiar to many of us – phone overheating during wireless charging. It was quite amicable how the product tackled this common problem and managed to keep my phone cold to touch during a charging session. The build quality, presentation of the product, and the instant cooling effect were impressive factors.

The clever design enables us to use our phones during charging without the fear of excessive heat. However, the issue of condensation building up in the phone due to the cooling technology needs to be addressed in more detail by the manufacturer.

Product Verdict

Without a doubt, the ESR Halo Lock Wireless Car Charger with CryoBoost is not your average charger. However, the product claims require more clarity. Is it truly faster than any other MagSafe charger as claimed? The charger maxes out at 7.5 watts, half of Apple’s MagSafe’s 15 watts, which leaves their claim rather questionable.

Overall, the product can certainly be a valuable addition if you’re looking for a handy, in-car wireless charger that keeps your phone cool. However, it may not necessarily outdo a MagSafe charger in charging speed. For potential buyers, it is imperative to consider these aspects before purchasing.

In conclusion, the ESR Halo Lock Wireless Car Charger with CryoBoost is a commendable invention, potentially able to reduce phone overheating issues. Still, specific details, like condensation risks and charging speed, need to be considered and clarified to better justify its worth. Happy shopping!
