The devices we use require plenty of power to reach maximum battery capacity. And with the amount we use our devices, like our smartphones, it’s important to have a quick, safe, and inexpensive solution at the ready. ESR’s latest Qi2 MagSafe chargers with CryoBoost might be exactly what you’re looking for. Launched in early 2024, these chargers are designed to give you MagSafe-like speeds without the hefty price tag.

What’s even more exciting is that they come equipped with ESR’s 2nd-Gen CryoBoost technology, which features an improved duct design for better active cooling. This means your device stays cool while charging quickly, and ESR’s own tests show it can fully charge an iPhone 15 Pro Max in just 2 hours. That’s at least 30 minutes faster than other Qi2 chargers out there.

What is CryoBoost?

CryoBoost is ESR’s innovative answer to one of the most persistent problems with wireless charging: heat. Wireless chargers naturally generate heat as they transfer energy to your device, but when that heat builds up too much, it can slow down or even stop the charging process. CryoBoost tackles this issue head-on with advanced cooling technology that ensures your phone stays cool, allowing for ultra-fast wireless charging without the risk of overheating.

So, how does CryoBoost work? It’s all about smart design and precision engineering. ESR initially introduced CryoBoost in 2022, but they’ve refined it further in 2024 to make it even more efficient. The key lies in its specialized cooling fan and heat-dissipating components, which work together to maintain an optimal temperature during charging.

Unlike other air-cooled chargers that rely on heat transfer between the charger and the phone, CryoBoost directs a focused stream of cool air directly onto the back of your phone. This not only lowers the phone’s temperature but also prevents condensation, which can be harmful to both the phone and its battery.

ESR’s semi-arc parabolic duct, combined with a fan that’s been engineered down to the smallest detail, ensures a smooth and powerful airflow. The duct’s all-open layout enhances cooling efficiency while keeping noise levels to a whisper; less than 25 dB. Even at high speeds, the fan remains quiet thanks to its optimized blade design, which minimizes turbulence and reduces secondary flow between blades.

The result is a charger that not only cools effectively but does so quietly and efficiently, all while looking sleek and modern.
