Performance
The special feature is the CryoBoost cool down that ESR claims can reduce temperature created by the charge process . With a cool battery , charge should be more efficient and therefore faster .
Although I am aware of the force of high temperature on battery performance and have tested enough charger to know that some can escape quite hot , I was sceptical about the claims . perchance it was the CryoBoost name that sounds a bit too super - hero to ring true .
However , in my tests there is no question that the ESR 3 - in-1 Wireless load Set with CryoBoost charged my test iPhone 16 Pro significantly quicker than two other wireless chargers I tested it against ( one Apple - certified MagSafe , and one Qi2 ) .

While both MagSafe and Qi2 support up to 15W in wireless charging , the results were quite clear . Where the MagSafe battery charger took over two hour to buck the phone to 80 % and the standard Qi2 charger a lilliputian quicker at an time of day and 45 instant , the ESR CryoBoost Qi2 charger took just over an minute to recharge the phone to 80 % .
Charging times did deviate — maybe also down to temperature — and in one test we charged from 5 % to 100 % in one hour and eight minutes using the ESR . As such , we can confidently say that the CryoBoost technology dramatically reduces iPhone wireless charging time .
buck slows down as the battery fills up — to protect the phone by not fire - hosing power into its shelling when it needs only a few percent to accomplish full cathexis — the best stage to calculate at is between 0 % and 50 % . Using the very fast wireless charger there is — Apple ’s 25WMagSafe Charger — we charged our iPhone 16 Pro from 0 % to 50 % in just 30 minutes . The 15W CryoBoost 3 - in-1 Charger took just 10 minutes longer — and remember that it , unlike the simple Apple Charger , can charge up three equipment at the same clip .
When charging, the ESR CryoBoost Charger glows to show its fan-based cooling tech.

Should you buy the ESR 3-in-1 CryoBoost Charger?
We like the tough yet slight ESR 3 - in-1 Wireless Charging Set even without the young CryoBoost cooling engineering . Its a neat , dim-witted design with the supply handiness of the detachable Watch charging unit . We would certainly recommend spend the pocket-size extra amount to significantly speed up wireless charge times .
