MagSafe & Qi2 Car Chargers – Magnetic Phone Mounts & Wireless Charging

What's the fastest wireless car charger ESR sells right now?

The OmniLock Magnetic Car Charger (25W, CryoBoost, Air Vent) is the fastest in the lineup, charging Qi2-compatible iPhones at up to 25W.

Its built-in CryoBoost fan actively cools the phone during charging so the speed doesn't drop off from heat buildup, which is usually what slows down cheaper magnetic chargers after ten or fifteen minutes on the road.

What's the difference between the 25W and 15W car chargers?

The 25W charger uses the Qi2 25W protocol, while the 15W charger uses an earlier Qi protocol that caps charging at 15W.

The other main difference is thermal management. The 25W OmniLock model runs active CryoBoost cooling to sustain that higher output, while the standard HaloLock 15W models rely on passive heat dissipation. There's also a 15W CryoBoost HaloLock model that adds active cooling at the lower wattage.

For long drives with navigation apps running, the 25W CryoBoost model holds up better; for a short commute, any of the 15W chargers will do the job.

Do I need a mount that charges, or just a mount?

Depends on your habits. If your phone's already charged before you drive and you just need it steady for navigation or calls, then a mount will suffice.

ESR has three charging-free mount options to pick from: the HaloLock Magnetic Vent Mount at $19.99 is the simplest and most rated, with 117 reviews behind it; the OmniLock Magnetic Car Mount (Air Vent) at $22.99 steps up with a longer adjustable arm and a 1,800 g magnetic rating for heavier phones and a greater range of positions; and the OmniLock Suction Cup mount works on the windshield or dash instead of an air vent.

If you tend to get in the car with a half-dead battery, or frequently commute or travel long distances, one of the charging models makes more sense, as it can keep your device powered throughout the journey.

Do these work with a MagSafe case, or only caseless iPhones?

They work through a genuine MagSafe case. The case's magnets line up with the magnetic ring in the mount the same way they would on a caseless phone.

Keep the case under 3 mm thick, and avoid cases with metal plates or rings on the back, since metal disrupts alignment and can reduce charging efficiency.

Can I use this with a Samsung Galaxy, since Samsung doesn't build in MagSafe?

No, not on its own. Samsung phones don't ship with the magnetic ring that MagSafe and Qi2 rely on.

Pairing a Galaxy S25 or S26 with an ESR Classic Hybrid Case adds that magnetic layer to the back of the phone, letting it snap onto the same mounts or chargers and charge the same way an iPhone does.

Will using a magnetic car charger interfere with CarPlay or Android Auto?

No. CarPlay and Android Auto connect to the car's system via a USB cable or, for wireless setups, a combination of Bluetooth and Wi-Fi. This has nothing to do with the wireless magnetic charging connection.

Navigation can run through CarPlay while the phone charges on the mount.

How strong is the magnetic hold? Will it keep a heavier phone in place?

The OmniLock 25W CryoBoost charger uses a magnetic array rated up to 1,600 g and is built to keep phones like the iPhone 17 Pro Max or Samsung S25 Ultra steady through bumps and turns.

So no matter how bumpy the road, your phone stays securely in place.

Where should I mount it: the air vent, dashboard, or windshield?

The OmniLock 25W and the HaloLock Magnetic 15W both clip onto an air vent.

The HaloLock Dashboard 15W sticks directly to a flat surface instead, which some drivers prefer if their vents are angled awkwardly or don't give a firm grip.

The suction-cup OmniLock mount can go on either the windshield or dash, depending on where you get better line of sight.

Is there a faster standard coming after Qi2, and should I wait for it?

Since the Wireless Power Consortium (WPC) launched Qi2 in 2023, wireless charging has advanced quickly. Qi2 initially introduced 15W charging with its Magnetic Power Profile (MPP) magnetic alignment system.

In 2025, the standard evolved to Qi2 25W (AKA Qi2.2), delivering nearly 70% more charging power and making it the fastest Qi-certified wireless charging standard currently available.

Faster wireless charging standards will likely emerge in the future, but there is no need to wait if a faster charger would be useful now. The 25W CryoBoost model offers the fastest wireless charging currently available in the lineup, so if faster charging would make a difference to everyday routines, such as getting a quick top-up during a commute, there’s little reason to hold off.

What's the difference between the HaloLock and OmniLock magnetic car mounts?

The HaloLock Magnetic Vent Mount is the simpler, lower-cost option: one arm length, fits most vents, and has over a hundred reviews backing it up.

The OmniLock Magnetic Car Mount (Air Vent) costs a few dollars more but adds a longer adjustable arm for finding the right viewing angle, 360° rotation, and a magnetic hold rated to 1,800 g, which matters more if you're using a heavier phone or a case with some weight to it.

Neither charges the phone — for that, you'd want one of the OmniLock or HaloLock charging models instead.
