MagSafe is the first wireless charging standard used by the iPhone 12 series to solve the problem of wireless charging alignment difficulties and is also used in the iPhone 13 series.

Wireless charging, also known as inductive charging, is a technology that uses a non-physical contact method to achieve power transmission. It uses inductive coupling to transfer energy from a power supply to a device. Since the energy is transmitted between the charger and the electric device through inductive coupling, no wired connection is required between the two.

In order to fast charge a device wirelessly, please refer to the following details:

1. The devices have to support wireless charging and both the device and the wireless charger will have to support the same fast charging technology.

2. The wall charger has to be a Quick Charge or Power Delivery charger.

3. For non-magnetic wireless chargers, the phone case has to be less than 5mm without any magnetic and metal attachments, pop sockets, keys, or credit cards; for magnetic wireless chargers, please use a magnetic phone case only.

Most of Anker’s non-magnetic wireless chargers can provide a standard 5W charging mode for Qi-compatible devices, a fast 7.5W mode for iPhone 8 and newer phones, a fast 10W mode for Samsung phones that support wireless charging, and a fast 15W mode for Pixel 3 and newer models, etc.

Here are some recommendations for your reference:

7.5W fast mode for iPhone: 313 Wireless Pad, 313 Wireless Stand (not compatible with iPhone 12 mini and 13 mini), and magnetic wireless chargers.

10W fast mode for Samsung phones: 313 Wireless Stand, 313 Wireless Pad, and PowerWave 7.5 Stand.

15W fast mode for Pixel/LG phones: PowerWave II Stand, PowerWave II Pad, PowerWave Pad Alloy, and PowerWave Sense Pad Alloy.

Samsung Galaxy Note 10 Plus and some later models, such as the S22 Ultra and Tab S7+, reach even higher charging speeds of 45W with the latest USB Power Delivery 3.0 PPS (Programmable Power Supply) charging, and "Super fast charging 2.0" appears on the lock screen. In order to charge it to the fastest speeds, it requires a 45W charger with an unusual 9V/5A rating, which means it also requires a 5A cable.

Due to this latest PPS charging protocol, most Anker 45W chargers will show "Super fast charging" only instead of "Super fast charging 2.0" on the phone screen, despite the full charging time being almost exactly the same as Samsung's 45W wall charger. "Super fast charging 2.0" will appear when using our latest GaNPrime Chargers, 717 140W Charger and 736 Nano II Charger, but may not appear when using multiple ports simultaneously due to the reduced wattage of the single USB-C port. Regardless of which Anker 45W PPS charger you opt for, you can expect your phone to be fully charged in around an hour.

In summary, the following prerequisites are required to achieve Super fast charging 2.0" mode:

A USB-C to USB-C cable rated at 5A (100W)

A Samsung phone supports 45W fast charging

A 45W or powerful charger that follows the latest 9V/5A PPS charging protocol, such as our 736 Nano II Charger and GaNPrime Chargers.

The indicator on the wireless charger often flashes when the wireless charger detects a foreign object, such as a metal attachment or an incompatible phone or phone case; additionally, it could also be the power supply has a low voltage. Please refer to the following troubleshooting tips that may help locate and resolve the problem:

Please ensure the device being charged does support wireless charging.

Reboot your phone and then try again.

Charge the phone with its case removed since bulky cases or cases with metal components could interfere with charging.

Try a powerful wall charger (9V/2A) and cable.

Place the phone at the center of the wireless charger if it’s a wireless charging pad.
