Why won’t my iPhone stay on the magnetic charging pad?
Phone stability issues are usually caused by incompatible phone models or non-magnetic cases
Please check:
●
Your phone is an iPhone with MagSafe (iPhone 12 series or later)
●
Your phone case is one of the following:
●
An official MagSafe case
●
A standard case with anESR HaloLock™ Universal Ring
Why is my phone not charging/not charging stably?
Non-charging or unstable charging is usually caused by incompatible phone models, not using the included power adapter, or issues with your phone case or mounting
Please check:
●
Your phone is an iPhone with MagSafe (iPhone 12 series or later)
●
You are using the included 24W DC power adapter
●
Your magnetic case is less than 5 mm thick and there are no metal attachments or credit cards between the case and your phone
●
Your phone is placed on the phone charging pad and not on the AirPods charging pad
●
The charger is in CryoBoost™ charging mode (with phone-cooling fan and status light on)
Additional information:
●
Wireless charging is not as fast as wired charging
●
Charging is slower if the charger is in dark charging mode (with phone-cooling fan and status light off)
●
The charger has a maximum output of 7.5W for iPhone
●
Optimized Battery Charging is enabled by default for iPhones running iOS 13 or later. With this feature enabled, your iPhone will throttle charging after 80%. For more information on this, please read: https://support.apple.com/en-us/HT210512
●
To improve the charging speed, limit the number of applications you have open concurrently on your phone
Why are my AirPods not charging/not charging stably?
Non-charging or unstable charging is usually caused by an incompatible AirPods case, or not using the included power adapter
Please note:
●
Magnetic wireless charging is only available for AirPods with MagSafe or AirPods without MagSafe (that support wireless charging) with a magnetic case. We recommend using anESR HaloLock™ Magnetic Soft Case
●
If you are charging AirPods without MagSafe (that support wireless charging) with a non-magnetic case, ensure the case is less than 4 mm thick and the AirPods are positioned in the center of the AirPods charging pad
●
Make sure you are using the included 24W DC power adapter
Additional information:
●
Wireless charging is not as fast as wired charging
●
The charger has a maximum output of 5W for AirPods
What is the reusable adhesive pad for?
●
You can attach the reusable adhesive pad to the bottom of the charger base to provide added stability
●
Be sure to attach the adhesive pad with side A affixed to the charger base. The adhesive on side B is reusable, allowing you to reposition the charger as needed
Is it normal to hear the fan when the phone is charging?
●
This charger uses an ultra-quiet fan to keep your phone cool for a faster charging speed. In normal conditions, the phone-cooling fan noise is not noticeable; however, it may be perceptible in very quiet environments
●
The phone-cooling fan automatically turns on when your phone is charging and turns off when your phone is fully charged or removed from the charger
●
You can turn off the fan at any time by pressing the CryoBoost™ on/off button (on the base of the charger) to enter dark charging mode. This turns off the phone-cooling fan and status light(s). Note: CryoBoost™ fast charging is not available in dark charging mode
Do the charging pad status lights stay on during charging?
●
When the phone is attached to the phone charging pad, the phone-cooling fan and status light automatically turn on
●
When the AirPods are attached to the AirPods charging pad, the status light in front of the AirPods charging pad automatically turns on
●
You can turn off the status light(s) at any time by pressing the CryoBoost™ on/off button (on the base of the charger) to enter dark charging mode. This turns off the phone-cooling fan and status light(s). Note: CryoBoost™ fast charging is not available in dark charging mode

The included 24W DC power adapter can only be used safely up to 2,000 m above sea level. Using the power adapter over 2,000 m above sea level may lead to electrical leakage and the potential for electric shocks.
