TL;DR
ESR's OmniLock is a vent-mounted MagSafe car charger that supports 25W Qi2.2 charging and includes onboard heat-management. It requires at least 35W of input power for peak speeds and ships with a DC adapter and cables to meet that requirement.
What happened
ESR introduced the OmniLock, a MagSafe-style car charger designed to deliver up to 25 watts using the Qi2.2 specification. The unit is built around a magnetic charging puck attached to an adjustable arm and secures to a vehicle air vent with the included mount. ESR bundles a DC adapter and a USB-C cable—necessary because the charger requires a minimum of 35 watts of input to attempt Qi2.2 rates; typical built-in USB-A or some USB-C ports in cars may not supply enough power for top speeds. The package also contains an extra USB-A port capped at 18W and a 40W USB-C port on the adapter, which ESR recommends using for the charger. The OmniLock uses vent mounting to promote airflow and includes an active cooling or heat-management feature. After installation, the charger powers up when the car starts and accepts an iPhone or other compatible device for wireless charging.
Why it matters
- Faster in-car wireless charging: Qi2.2 support aims to increase charging speed compared with older car wireless chargers.
- Heat control in vehicles: built-in cooling addresses thermal limits that can throttle wireless charging in warm cabin conditions.
- Power requirements matter: consumers must ensure a 35W+ supply to achieve advertised speeds, affecting compatibility with many factory USB ports.
- Complete package: including a DC adapter and cables removes the need to hunt for a suitable power brick to reach peak output.
