BMX SolidSafe Air hands-on: The thinnest Qi2 power bank yet

I've been searching for the perfect MagSafe battery pack for years. The market is flooded with options, but they all share the same fundamental compromise: bulk. That changed when I discovered BMX's new SolidSafe Air, a 5,000mAh power bank that measures less than 6.8mm thick. After using it for over a week alongside my iPhone 17 Pro, here's what makes this the thinnest Qi2 power bank yet.

Design and build quality

The SolidSafe Air immediately stands out for its engineering achievement. BMX managed to pack 5,000mAh of solid-state battery capacity into a chassis that's just 6.88mm thin and weighs only 116g. For context, that's thinner than Apple's official MagSafe Battery Pack for iPhone Air (7.7mm) and significantly lighter.

The build quality impresses with a brushed titanium finish on the front that gives it a premium feel while providing passive grip. The inner portion features a soft rubberized texture that helps maintain a secure connection to your iPhone. It comes in three colors: Silver, Gold, and Black.

Compatibility and fit

BMX markets this as the "iPhone Air companion," but I found it works excellently with standard iPhone models too. My iPhone 17 Pro (8.75mm thick, 206g) pairs perfectly with the SolidSafe Air. Some power banks designed for Pro Max models have a lip that extends over smaller iPhones, but the SolidSafe Air aligns flush on all sides.

The slightly wider footprint compared to other power banks is barely noticeable in daily use. What matters is that it adds minimal bulk to your device while maintaining a secure magnetic connection.

Charging performance

The SolidSafe Air delivers on its Qi2 15W wireless charging promise. When my iPhone 17 Pro dropped to 20-30% battery, attaching the power bank would charge it to 90-95% while I continued using the phone. The charging process generates only slight warmth—nothing concerning.

Beyond wireless charging, the power bank offers:

• 20W USB-C output (Power Delivery)
• Ability to charge two devices simultaneously
• 15W USB-C input for recharging the power bank itself

The 15W input means the power bank charges from 0% to 100% in under two hours, which is convenient for quick top-ups.

Practical considerations

While the SolidSafe Air excels in portability, there are trade-offs. The lack of an LCD display means you can't see exact battery percentage or charging diagnostics. LED indicators provide basic status information, but I missed having more detailed feedback.

This compromise likely helped achieve the ultra-thin profile—adding a display would have increased thickness or reduced battery capacity. For many users, including myself, the slim form factor outweighs the need for detailed battery information.

Pricing and availability

The BMX SolidSafe Air is available now on BMX's website for $59. This positions it competitively against other premium MagSafe battery packs while offering the unique advantage of being the thinnest option available.

Final thoughts

The SolidSafe Air represents a significant achievement in portable power bank design. It proves that you don't need to sacrifice capacity for portability. The combination of Qi2 15W wireless charging, solid-state battery technology, and an ultra-thin profile makes this the best option for users who prioritize minimal bulk.

Whether you're an iPhone Air user or simply want a power bank that doesn't add noticeable weight to your everyday carry, the SolidSafe Air delivers on its promise of being the thinnest Qi2 power bank available today.
