# ESR’s Groundbreaking Qi2 Chargers: Transforming Mobile Accessories
In the rapidly changing landscape of mobile accessories, ESR has carved out a prominent position, especially known for its MagSafe offerings. As the leading brand for MagSafe products by sales on Amazon, ESR is committed to innovation and broadening its product array. Earlier this year, they unveiled new Qi2 chargers as an economical substitute for Apple’s MagSafe. Now, with the introduction of their second-generation CryoBoost technology, ESR aims to transform the charging experience for iPhone users.
## Exploring CryoBoost Technology
CryoBoost, developed by ESR in 2022, tackles one of the primary obstacles linked to wireless charging: overheating. Standard wireless chargers frequently heat up, resulting in decreased charging speeds or even total charging failures. ESR’s CryoBoost technology integrates a fan and sophisticated heat-dissipating components, guaranteeing a steady 15W charging speed without the concerns of overheating.
The latest CryoBoost chargers boast an enhanced duct design that promotes better airflow, leading to even superior cooling. Operating at less than 25 dB, the fan is quieter than a typical whisper, making it ideal for any setting. Unlike other chargers that merely manage the cooling of the charger itself, CryoBoost channels airflow onto the back of the phone, keeping it up to 5.5°C cooler than competing products.
## 3-in-1 MagSafe Charger with Qi2 and CryoBoost
A highlight in ESR’s new collection is the 3-in-1 MagSafe charger, which is both Qi2 and Apple certified. This adaptable charger can simultaneously energize your iPhone, Apple Watch, and AirPods, all while employing CryoBoost technology. For example, an iPhone 15 Pro Max can reach a full charge in merely two hours—30 minutes faster than other Qi2 chargers.
Moreover, the accompanying Apple Watch charger is fast charging certified, allowing an Apple Watch Series 9 to attain 7% in just over an hour, significantly faster than uncertified options. With certification ensuring reliable performance even post-OS updates, this charger is a sound investment for Apple enthusiasts. It is available for $69.99 on Amazon.
## MagSafe Car Charger with Qi2 and CryoBoost
For those who often charge their devices while on the move, ESR’s latest MagSafe car charger is essential. Utilizing Qi2 and CryoBoost technology, this charger stands out as the fastest available, effectively addressing heat challenges that can occur from GPS use and extended sun exposure.
The charger features a remarkable grip, courtesy of 18 strong N52 magnets, ensuring a firm hold on your phone even during sharp turns or bumpy journeys. It offers dual mounting options: an air vent clip or a dashboard mount, providing users with installation flexibility. The MagSafe Car Charger retails for $39.99 on Amazon.
## Qi2 MagSafe Battery Pack with Kickstand
Completing ESR’s cutting-edge range is the Qi2 MagSafe battery pack, boasting a 5,000mAh capacity. This battery pack supports fast charging at 15W, positioning it as a superior choice compared to most current MagSafe battery banks. With Apple halting its official MagSafe Battery Pack, ESR’s product fills a vital void in the market.
Designed with a kickstand, the battery pack allows for convenient charging on-the-go while maintaining an ultra-slim profile at just 15.5mm thick. It can recharge an iPhone 15 Pro Max to 84% in under 2.5 hours, surpassing standard 7.5W battery packs. Its grip strength of up to 1,200g guarantees that your device stays secure and cool throughout use. This battery pack is available for $39.99 on Amazon.
