We love the convenience of wireless charging, which eliminates the hassle of dealing with proprietary ports and cables. But the idea of being able to simply put your phone on a wireless charger and go from zero to 100 percent in a short time hasn’t always been realistic.
That’s partly because your phone and charger need to be properly aligned to get the fastest and most efficient wireless charging. Only devices that support magnetic alignment via Qi2 or MagSafe can automatically click and lock into place.
It’s also because unwanted heat can wreak havoc on wireless charging performance. Keep in mind that the energy wasted by generating heat is energy that will not ultimately make it into your battery. Excessive heat can also damage the battery, so anything that can be done to reduce the temperature is definitely worth considering.
ESR’s trio of fully certified MagSafe and Qi2-compatible wireless charging accessories can solve both problems – at home, on the road and even in your car. Their integrated CryoBoost v2 technology is an ultra-quiet, ultra-cooling system that can reduce the temperature of your iPhone by as much as 5.5 degrees compared to competing brands.
Lower temperatures can charge your device significantly faster, more safely and at a fraction of the price of Apple’s own charging accessories.
ESR 3-in-1 MagSafe charger with Qi2 and CryoBoost
For the Apple user with multiple devices: the 3-in-1 MagSafe charger allows you to charge iPhone, Apple Watch and AirPods in one go.
With its precision-engineered advanced cooling fan that runs at less than 25 dB (that’s less than a whisper from 6 feet away), it’s ideal for juicing your devices at the side of your bed at night, or even during the day in the office, without fear of disturbing noise.
A parabolic duct design maximizes airflow, keeping both the charger and your connected devices cool, while reducing the build-up of dangerous heat and condensation that could otherwise damage your battery.
This Apple certified ESR charging stand can deliver 15W of power and is fast too. Expect the iPhone 15 Pro Max to fully charge in just two hours – that’s 30 minutes faster than comparable chargers. And Apple Watch Series 9 could reach 75% in 70 minutes, reducing the working time of competing devices by 50 minutes.
ESR MagSafe car charger with Qi2 and CryoBoost
Safety comes first when charging the iPhone in the car. No one wants to deal with a phone popping out of an open window or getting stuck under the pedals, especially while trying to follow a navigation route. Heat can also be more problematic than normal if the screen is active and the sun is shining on the windshield.
ESR’s MagSafe Car Charger stands out for its secure 1,600g magnetic grip, achieved using an array of 18 N52 magnets that hold your iPhone firmly in place. You can clamp it to a vent or mount it to the dashboard, making it compatible with any brand of vehicle. Whatever the terrain, your iPhone isn’t going anywhere.
You’re not sacrificing performance for safety here, as the MagSafe car charger delivers the same 15W power and advanced cooling system as the rest of the ESR CryoBoost range.
Expect iPhone 15 Pro Max to reach 100 percent in just two hours and seven minutes – using GPS! That’s 113 minutes faster than some other Qi2 car chargers, and still 35 minutes faster than those with cooling fans.
ESR Qi2 MagSlim standard power bank (5,000 mAh)
Featuring a multi-award-winning built-in stand design, the Qi2 MagSlim Kickstand Power Bank 5,000mAh is the thinnest Qi2 charger on the market, perfect for space-saving charging and on-the-go charging.
It is a great travel companion and can be securely attached to iPhone with a strong magnetic force of 1200g. It has 5,000 mAh of portable power for a single charge, keeping you connected until you’re next near a wall socket.
For storing in a pocket or bag, the slim 15.5mm design is welcome, and about 38% slimmer than comparable devices. The smaller your pocket, you would think that the heat could become a problem, but continuous temperature monitoring keeps your iPhone as much as 20 degrees cooler than those other power banks.
And it’s still fast: iPhone 15 Pro reaches 84% in two hours and 25 minutes.
Frequently asked questions
What is CryoBoost?
CryoBoost is an ESR-developed cooling technology, now in its second generation, that combines a precision-engineered advanced cooling fan with parabolic ducts and heat-dissipating components to maximize airflow and cool devices during wireless charging. By reducing heat, CryoBoost can speed up charging and reduce potential damage to the battery.
What is MagSafe?
Originally designed as a safety feature for MacBook charging cables, this magnetic technology was later redesigned for the iPhone and its accessories, including more recent models of Apple Watch and AirPods. It uses a series of magnets hidden within the Apple device to snap and lock connected accessories into place. It is now commonly found in Apple accessories including iPhone cases, chargers, docks, power banks and wallets.
Which Apple devices support MagSafe?
MagSafe was introduced on the iPhone 12 series and is compatible with iPhone 12/13/14/15/16 families. The technology is also compatible with Apple Watch Series 7/8/9/10 and Ultra 1/2, plus AirPods 3/4/Pro 2 via their wireless charging case.
What is Qi2?
Qi2 is a wireless charging standard that can deliver up to 15W of power and supports magnetic alignment for faster and more efficient charging.
Which phones support Qi2 wireless charging?
Qi2 is supported by the iPhone 12/13/14/15/16 families. It’s also available for Android phones, but so far only the HMD Skyline has launched with support for the new wireless charging standard.
