Anker Launches $100 Prime Foldable Charger With 25W Qi2.2 and AirCool

Q: Can Anker's 25W charger fast-charge an iPhone 17 without degrading its battery life, even with the cooling fan turned off?

Yes, it can fast-charge an iPhone 17, but turning the cooling fan off makes it less likely to sustain 25W and increases the risk of long-term battery wear from heat. The Anker Prime Foldable MagSafe Charger supports Qi2.2 wireless charging up to 25W for iPhone 16-era and newer models, which includes the iPhone 17 line. With the included 45W USB-C adapter, it is built to deliver that top speed under the right conditions. The key issue is heat. Fast wireless charging is less efficient than wired charging and naturally produces more heat. Battery experts and the product’s own design point to the same fact: elevated temperature, not fast charging alone, is the main driver of lithium-ion degradation over time. That is why Anker added the 19 dB AirCool fan and promotes it as a battery-protection feature. If the fan is off, the charger and phone will rely on passive cooling and the iPhone’s own thermal safeguards. In practice, the iPhone may reduce charging speed or pause charging if temperatures rise too much. That helps prevent immediate damage, but it also means you may not get sustained 25W performance, and repeated hotter charging sessions can still age the battery faster. So the charger is designed to fast-charge safely, but the safest setup for battery health is with the fan on, good airflow, and no heat-trapping case or bedding around the phone.

Under $100, Anker’s new Prime Foldable MagSafe Charger unfolds into a 3-in-1 stand for iPhone, Apple Watch and AirPods, then folds to roughly 96mm by 60mm by 23mm for travel.
25W Qi2.2 charging on the MagSafe pad reaches the current standard’s top speed and can take an iPhone 17 Pro to 50% in about 26 minutes, but only with the included 45W USB-C adapter.
AirCool—a built-in 19 dB fan in the base—pulls heat from the phone during fast wireless charging, and users can switch it off with a double-tap on the LED ring.
The charger supports iPhones from the 12 onward, Apple Watch models back to Series 1 with fast charging on Series 7 and later, and wireless-charging AirPods cases.
Anker positions the model as a travel-friendly addition to its charging lineup, with the current price cut from $150 to below $100 marking a 33% discount.
