ESR HaloLock vs Belkin BoostCharge: Which wireless charger should you buy?
ESR knew what it was doing with the HaloLock. The magnetic wireless charger is one of the thinnest I’ve tested, and most of the time, I didn’t even notice that I had a charger attached to my phone. It attaches magnetically to the back of a phone, and there’s even a USB-C port that lets you charge a second device at up to 20W.
The HaloLock usually costs $35, but it is now down to just $24 for Prime Day, which is a terrific price. This is one of the best magnetic chargers available, and if you need a portable option that you can take anywhere, it’s the one I’d recommend.
I’ve been covering mobile technology for over a decade, and I’ve tested nearly every major wireless charger released. Both the ESR HaloLock and Belkin BoostCharge have been part of my daily routine for months while testing dozens of phones.

ESR HaloLock: Incredible value at this price point
Coming in at just 107g, the HaloLock has the distinction of being one of the lightest magnetic chargers around. And at 0.3 inches, you won’t even notice it while it’s attached to your phone. The design is a clear point of differentiation, and the build quality is fantastic.
I’ve been using this charger for the better part of two months now, and it has been rock-solid. The magnetic connection is strong enough that I’ve accidentally knocked my phone off my desk multiple times, and the charger stayed put both times.
It also boasts good charging efficiency, and I had no issues charging a variety of Android phones, as well as my iPhone 16 Pro Max, with the charger. The added USB-C port allows for convenient charging of a second device at up to 20W.
The kickstand feature turned out to be more useful than I initially thought. Perfect viewing angle for video calls, and it’s sturdy enough for daily use. After extensive testing, the mechanism shows slight loosening but remains functional.
The HaloLock has everything you need if you’re looking for a reliable charger that you can take anywhere. It’s also available in four color choices.
✅ Recommended if: You need a portable charger that travels well. The HaloLock is perfect for users who prioritize mobility and don’t need multi-device wireless charging.
❌ Skip this if: You need faster iPhone charging or want to charge multiple devices wirelessly. The 7.5W iPhone limitation may be restrictive.
Belkin BoostCharge: Premium experience with a matching price
Belkin knows what it’s doing when it comes to charging tech. I used all of the brand’s chargers, power banks, cables, and Qi chargers, and they’ve all been reliable. The BoostCharge is my go-to charger while at my desk, and the multi-device design, combined with built-in positioning, makes it a standout choice.
The Qi2 certification ensures genuine 15W charging, making a noticeable difference in daily use. Testing with my iPhone 16 Pro showed significantly faster charging compared to the HaloLock – approximately 30 minutes to reach 65% from 15% instead of 45 minutes.
Multi-device charging is a key feature that justifies Belkin’s premium pricing. The ability to charge three devices simultaneously isn’t just convenient – it’s a genuine productivity enhancer for anyone managing multiple Apple devices daily.
Belkin didn’t change much from their previous designs, and it looks similar to other premium chargers. You get the same clean aesthetics, and at around 200g, it’s meant for desk use rather than portability.
The charging station boasts solid build quality, is designed to withstand sustained use, and features minimal use of cheap materials. The engineering feels solid across the board.
✅ Recommended if: You own multiple Apple devices and value charging efficiency. The BoostCharge excels for users who prioritize charging efficiency over budget. If budget is the primary consideration, or you typically charge single devices, this may be the best option. However, if you usually charge multiple devices, the device will charge only one device. The primary concern is whether you typically charge for just a single device. If the budget is the primary consideration, or you usually charge single devices, skip this. If the primary concern is only a single device, skip this section. If the budget is your primary concern, or you typically charge for only a single device, skip this step.

Performance testing across multiple devices
I’ve tested both chargers with dozens of phones over the past several months while reviewing a range of devices, from Chinese flagships to the latest iPhones. Here’s what extensive testing revealed:
iPhone 16 Pro charging (15% to 65%):
- ESR HaloLock: 42-45 minutes consistently
- Belkin BoostCharge: 28-30 minutes
Pixel 9 Pro XL charging (20% to 70%):
- ESR HaloLock: 35-38 minutes
- Belkin BoostCharge: 30-33 minutes
Both chargers demonstrated solid engineering appropriate to their price categories. Connection reliability has been perfect, with zero random disconnects or weird issues across months of testing. Heat management is fine on both, with the Belkin running slightly warmer during multi-device charging, but this is not concerning.
Magnetic alignment on both is excellent, significantly better than cheap knockoff chargers that frequently lose connection.
Which charger fits your workflow
The choice ultimately depends on your specific use case and budget parameters. Both offer genuine value, but they target entirely different user profiles.
Choose ESR HaloLock if: You want reliable wireless charging without premium pricing. Perfect for travel, single-device users, or anyone who appreciates the convenience of a kickstand. The $44 pricing represents outstanding value.
Choose Belkin BoostCharge if: You’re invested in the Apple ecosystem and want the fastest, most convenient charging experience. Multi-device capability and faster speeds justify the $80 pricing for power users.
I use both depending on the situation. ESR accompanies me to events and review trips, while the Belkin handles daily desk charging. Different tools for different scenarios, and both excel in their intended roles.
Where to buy and final thoughts
Both chargers are widely available. ESR HaloLock can be found on Amazon, ESR’s website, and sometimes Best Buy. Currently priced at $44, though I’ve seen it drop to $35 during sales events.
Belkin BoostCharge is available everywhere, including Apple Store, Amazon, and Best Buy. Pricing stays consistent at $80, with rare discounts during major shopping events.
After months of testing with dozens of devices, both chargers proved reliable and well-engineered. The ESR offers exceptional value and portability, while the Belkin provides premium features for users of its ecosystem. You really can’t go wrong with either choice – match the features to your specific needs and budget considerations.
