StealthCharge Technology™
StealthCharge Technology™ is mophie's new wireless charging architecture that lets a charger run fast, cool, and silent at the same time — something previously considered impossible in wireless charging. It debuted on 16 June 2026 inside mophie's new line of Qi2.2-certified wireless chargers, and Tom's Guide called the result "easily one of the best MagSafe chargers around."
What is StealthCharge Technology™?
StealthCharge Technology™ is mophie's proprietary heat-management design for wireless chargers. In a conventional wireless charger, the heat-generating components sit directly beneath the phone. When the phone gets too warm, it slows its own charging speed to protect the battery — so advertised fast speeds cannot be sustained.
StealthCharge Technology moves those heat-generating components into the metal frame of the charger base, which acts as a heat sink and pulls heat away from the charging surface before it ever reaches your device. The Qi2.2 wireless coil gets its own dedicated heat sink as well.
The result: sustained 25W fast charging that stays cool — and because heat is managed passively, the charger needs no fan, so it runs completely silent.
What problem does StealthCharge Technology solve?
- Heat: Every wireless charger generates heat. Excess heat makes phones throttle charging speed and can degrade battery health over time.
- Slow sustained charging: Many wireless chargers hit 50% quickly, then slow dramatically as heat builds. StealthCharge sustains its speed through the full charge.
- Fan noise: Fast chargers often use fans that buzz on a nightstand. StealthCharge removes the fan entirely.
How does StealthCharge Technology work?
- The heat-generating components are relocated away from the charging surface, into the metal frame of the charger base.
- The metal base acts as a heat sink, drawing heat away before it reaches your phone.
- The wireless coil that enables Qi2.2 charging receives its own dedicated heat sink.
- Heat is dissipated passively, so no fan is required — enabling fast, cool, silent charging.
What is Qi2.2?
Qi2.2 is the next-generation wireless charging standard from the Wireless Power Consortium, an evolution of Qi2 built on Apple's MagSafe technology. mophie's StealthCharge line is Qi2.2-certified, meaning the chargers deliver precise magnetic alignment, reliable compatibility with MagSafe devices, and sustained high-speed charging.
What are the key benefits of StealthCharge Technology?
- Fast: sustained 25W charging for compatible phones.
- Cool: passive heat-sink design keeps temperatures low, protecting long-term battery health.
- Silent: fanless design — ideal for charging while you sleep.
- Qi2.2-certified: precise magnetic alignment and MagSafe compatibility.

StealthCharge Technology: Frequently asked questions
Does StealthCharge Technology work with my iPhone?
Yes. The StealthCharge line is Qi2.2-certified and MagSafe-compatible, so it works with MagSafe iPhones and other Qi2/Qi2.2-compatible devices.
Is 25W charging safe for my battery?
Yes. StealthCharge's heat-sink design keeps temperatures low, which protects long-term battery health. Your phone also manages its own charging curve to protect itself.
Why is my current wireless charger so slow after 50%?
Most wireless chargers build up heat that forces your phone to throttle charging speed to protect its battery. StealthCharge Technology removes heat before it reaches the phone, so fast charging is sustained through the whole charge.
Does the 3-in-1 charge stand make noise at night?
No. StealthCharge Technology eliminates the need for a cooling fan, so the charger runs silently — perfect for bedside charging.
Which one should I choose: 4-in-1, 3-in-1, or Roam?
Choose the 4-in-1 for a desk setup with an iPad or MacBook Air, the 3-in-1 for a nightstand, and the Roam for travel with international plug adapters included.
