Here’s the low-down on the MagSafe standard and MagSafe power banks.
What is MagSafe?
MagSafe is the name of Apple’s accessory system that’s integrated into the iPhone 12, iPhone 13, iPhone 14, and iPhone 15 range. A ring of magnets on the back of the phone (and in MagSafe-enabled cases) lets you attach various magnetic accessories, like a battery pack that recharges the iPhone wirelessly, so you don’t need to hold it or carry a cable.
Does MagSafe reduce battery life?
There isn’t much evidence that MagSafe charging negatively impacts battery health, but it is less efficient than wired charging and can sometimes generate heat, which may degrade your battery faster. But other factors are more important, if you want to preserve battery health (such as never fully draining your battery).
What rate can MagSafe power banks charge at?
Most MagSafe power banks we have tested wirelessly charge at a rate of up to 7.5 watts, but Anker’s Qi2 power bank can charge at up to 15 watts.
Is USB-C better than MagSafe?
Wired charging is faster and more efficient than wireless charging, so if you plug your phone in via cable to any of the power banks above, you can expect to get more power, more quickly than you will using MagSafe or Qi2. MagSafe is simply more convenient.
What are the downsides of MagSafe?
Only some of Apple’s iPhones (12, 13, 14, and 15 series) support MagSafe, and it’s not officially compatible with Android phones. MagSafe is also less efficient than wired charging. Lost energy during wireless charging generates heat, which can have a negative impact on battery health.
Why do MagSafe power banks get hot?
MagSafe is not as efficient as wired charging, and power lost during wireless charging generates heat. MagSafe’s magnets reduce this problem, compared to Qi wireless charging, by ensuring the charging coils are aligned.
