Remember that satisfying *click* of MagSafe? What if you could have it on *any* case? Or even… on *any* phone? That’s the exact promise of the ESR HaloLock Ring. But is it a must-have accessory or just a gimmick? We find out.

Overall Rating:
4.8 / 5

Quick Verdict

For its low price, the ESR HaloLock Ring is an absolute game-changer. It delivers a magnetic lock that’s often *stronger* than Apple’s native MagSafe, and the included alignment tool makes installation foolproof. It’s the key that unlocks the entire MagSafe ecosystem for any phone.

The Good & The Bad

The 10 Big Wins (Pros)

  • Unlocks the entire MagSafe ecosystem for any phone.
  • Insanely strong 1,200g magnetic lock (often beats Apple).
  • Foolproof installation thanks to the included alignment jig.
  • Ultra-slim profile (only 0.5mm) adds zero bulk.
  • Revives your favorite non-MagSafe cases.
  • A must-have for Android users (Pixel, Samsung) wanting in on MagSafe.
  • Incredibly affordable price for the value provided.
  • Comes as a 2-pack (one for you, one for a friend… or a backup).
  • Durable, heat-dissipating metal construction (not cheap plastic).
  • Ferromagnetic ring design won’t interfere with wireless charging.

The 4 Minor Flaws (Cons)

  • Installation is a one-time deal; the adhesive is *very* permanent.
  • Doesn’t work on silicone, leather, fabric, or heavily textured cases.
  • It’s a visible ring. You have to be okay with the aesthetic.
  • Doesn’t *add* fast charging; just enables MagSafe connection.

Installation: Your 5-Minute Guide

This is the most critical part of the review. A bad installation means a useless product. Thankfully, ESR has made this almost impossible to mess up. Forget trying to eyeball the center of your phone; the included alignment jig is pure genius.

Step-by-Step Installation:

  1. Clean Your Case: Use the included alcohol wipe to thoroughly clean the *outside* of your phone case. Let it dry.
  2. Place the Alignment Jig: The jig has models for different phones (iPhone, Samsung Galaxy). Find your model and place the jig over your phone case. It should fit snugly.
  3. Peel the Sticker: Grab one of the HaloLock rings and peel off the adhesive backing. Be careful not to touch the sticky side.
  4. Set the Ring: Carefully place the ring into the guide on the alignment jig. The magnets will help it snap into the correct spot.
  5. Press Firmly: This is key. Press down *hard* on the ring for at least 30 seconds. Work your way around the circle to ensure the entire adhesive bonds.

Pro-Tip:

The adhesive needs time to cure. ESR recommends waiting 24 hours before using any MagSafe accessories. Don’t skip this step! It’s the difference between a good hold and a permanent one.

Performance: The “Snap” Test

A phone with the ESR ring attached to a MagSafe car mount

This is where the ESR HaloLock truly shines. We tested this on a Samsung Galaxy S23 Ultra case and an older iPhone 11 Pro case. The results were identical: the magnetic grip is *phenomenal*.

Accessory Compatibility:

  • MagSafe Chargers: It snaps onto an Apple MagSafe puck with a satisfying, deep *thud*. It finds the charging coil instantly, and charging begins without issue.
  • MagSafe Wallets: We attached a wallet and shook the phone. Violently. The wallet *did not budge*. The grip felt even more secure than the native MagSafe on an iPhone 14 Pro.
  • Car Mounts: This is the ultimate test. We slapped the phone onto a MagSafe car mount and drove over speed bumps and potholes. The phone stayed perfectly in place.

The 1,200g magnetic force isn’t just a marketing number; it’s a real, tangible benefit. You’ll never worry about your phone falling off an accessory. It’s *that* strong.

CRITICAL: Will It Stick to Your Case?

STOP! Read this before you buy. The HaloLock Ring is amazing, but it’s not magic. It *only* works on specific case materials.

YES: Works With

  • Smooth PC (Polycarbonate / Hard Plastic)
  • Smooth TPU (Thermoplastic Polyurethane)
  • Cases with *no* coating or texture
  • Metal or glass-backed phones (if caseless)

NO: Does NOT Work With

  • Silicone Cases (the adhesive can’t bond)
  • Leather Cases (textured, oily surface)
  • Fabric or Wood Cases
  • Any case with a heavy texture or ridges

The reason is simple: the 3M adhesive needs a smooth, non-porous surface to create a permanent bond. Check your case first!

Your Questions, Answered

Q: Does this give my phone 15W MagSafe charging?

A: No. This ring *enables the connection* to a MagSafe charger. The charging *speed* is still determined by your phone. An iPhone 11 will still charge at its max 7.5W Qi speed, but it will now be perfectly aligned and magnetically attached.

Q: Can I install this on my iPhone 14?

A: Yes! The main reason to do this is if you have a favorite non-MagSafe case that you want to keep using. This ring makes it MagSafe-compatible.

Q: Will this work on my Samsung Galaxy S23/S24 or Google Pixel?

A: Absolutely! This is one of the best use-cases. It adds MagSafe compatibility to Android phones, letting you use the *entire* ecosystem of mounts, wallets, and chargers. Just make sure to use the alignment jig for your model.

Q: Can I remove it and re-apply it?

A: No. The 3M adhesive is designed to be permanent. You *can* remove it (with some effort and goo-gone), but it is not reusable. This is a one-time application, which is why the alignment jig is so important.

The Final Verdict

For less than the price of a cup of coffee, the ESR HaloLock Universal Ring is one of the best tech accessories you can buy. It’s not a gimmick. It’s a high-quality, brilliantly designed solution that delivers on its promise: MagSafe for everyone. The magnetic strength is top-tier, and the alignment tool makes installation a non-issue.

If you have a non-MagSafe case you love, or an Android phone you want to upgrade, this is a 100% must-buy.
