The ESR OmniLock brings the next generation of Qi2.2 wireless charging to your car's air vent, delivering 25W of power with active cooling. But unlocking its full speed requires more than just a standard USB port.
The magnetic snap of a MagSafe charger in a moving vehicle is one of those small luxuries that, once experienced, becomes non-negotiable. It eliminates the fumbling with cables, guarantees perfect coil alignment for maximum efficiency, and provides a secure hold. The ESR OmniLock enters this crowded market not just as another magnetic mount, but as an early adopter of the new Qi2.2 standard, promising faster charging speeds and smarter thermal management. However, this performance comes with a specific power requirement that many car owners will need to address.
The Power Reality of Qi2.2
The headline feature of the ESR OmniLock is its 25-watt Qi2.2 charging capability. This is a significant step up from the standard 15W wireless charging that most MagSafe accessories have been limited to. But that power doesn't come for free. The OmniLock is explicit about its needs: it requires a minimum of 35 watts of power input to achieve Qi2.2 speeds.
This is the most critical detail for potential buyers to understand. Most cars, even newer models, have USB-A or USB-C ports that deliver far less power. A typical car USB-A port might provide 12W, while a basic USB-C port could be 18W or 20W. Plugging the OmniLock into these will likely result in it working, but at reduced speeds, falling back to slower charging protocols. To get the advertised 25W wireless charging, you need to use the included DC adapter that plugs into a car's 12V accessory outlet (the cigarette lighter). This adapter provides the necessary power delivery via its 40W USB-C port. It's a smart move by ESR to include this adapter in the box, as many manufacturers would have left users to source their own high-wattage car charger.
What's in the Box and Setup
The OmniLock system is straightforward. The package includes:
- The main Qi2.2 charging puck attached to a flexible arm.
- A vent mount adapter that clamps onto your car's air vent blade.
- The 35W+ DC car adapter with one 40W USB-C port and one 18W USB-A port.
- A USB-C to USB-C cable.
Installation is a familiar process for anyone who has used a vent-mount charger before. You first secure the vent mount clip to the puck's arm, then snap the assembly onto your car's vent. The cable routing is the only minor challenge, depending on your car's interior layout. You run the USB-C cable from the puck to the DC adapter, which you plug into your 12V outlet. The unit powers on when the car starts, and the magnetic alignment takes over as soon as you bring your iPhone near.
Active Cooling and Practical Design
A key component of the Qi2.2 standard is its approach to heat management. Wireless charging, especially at higher wattages, generates heat, which can throttle charging speeds to protect the device's battery. The OmniLock includes a built-in cooling fan to actively dissipate heat. This isn't just a gimmick; it's essential for maintaining the 25W charging speed for longer periods, especially during navigation or on hot days. The fan is quiet enough not to be distracting, and its presence provides confidence that the charger is working optimally.
The adjustable arm provides a good range of motion, allowing you to angle the phone for optimal viewing without blocking your view of the road. The magnetic hold is strong, keeping the phone secure even on bumpy roads.
The Verdict
The ESR OmniLock is a competent and forward-looking MagSafe car charger. It successfully delivers on the promise of faster Qi2.2 charging, but with a significant caveat: you must use the included DC adapter. If your car lacks a 12V outlet or you were hoping to power it from a built-in USB-C port, this won't meet your needs at full speed.
For those who can accommodate the adapter, however, the OmniLock is an excellent choice. It covers all the essential bases: high-speed charging, active cooling, a secure vent mount, and the convenience of MagSafe. It's a well-executed product from a company with a strong track record in the MagSafe ecosystem. If you're ready to step up to the fastest wireless car charging available and have the power setup to support it, the ESR OmniLock is easy to recommend.
