Wireless Charging Explained: MagSafe vs Qi, Watts, and What Actually Matters
Wireless charging should be simple: set your phone down, it charges. But the spec sheets are full of jargon. Here's what actually matters.
Qi vs. MagSafe — what's the difference?
Qi (pronounced "chee") is the universal wireless-charging standard supported by virtually all modern iPhones and Android phones. MagSafe is Apple's magnetic version: a ring of magnets snaps the phone into perfect alignment and allows faster, more efficient charging on iPhone 12 and newer. A MagSafe-compatible charger still works as a normal Qi pad for other phones — you just lose the magnetic snap.
How many watts do you really need?
- 5W: slow; fine overnight.
- 7.5W–10W: the sweet spot for most phones.
- 15W: fastest standard wireless speed, ideal for MagSafe iPhones and flagship Androids.
More watts means faster top-ups during the day. If you charge overnight, speed matters less than convenience.
Single pad or multi-device dock?
If you own a phone plus earbuds and a smartwatch, a multi-device dock clears the cable clutter on your desk or nightstand. Our 3-in-1 Wireless Charging Station powers an iPhone, Apple Watch and AirPods at once, and the 6-in-1 Wireless Charging Dock adds even more device slots with up to 15W fast charging.
Three quick tips
- Thick or metal-backed cases can block charging — most cases under ~3mm are fine.
- Center the phone on the coil; misalignment is the #1 cause of slow charging (MagSafe solves this automatically).
- Use a wall adapter that supplies enough power, or your charger can't hit its rated speed.
