SolidSafe Duo Power Bank Solves iPhone Duo Charging Problem What Shoppers Need to Know
New magnetic power bank designed specifically for iPhone Duo's unique shape and camera housing.
Apple’s introduction of the iPhone Duo foldable device at its September 2026 event brought exciting new possibilities for smartphone users, but it also created an unexpected challenge for accessory makers. The phone’s compact, passport-like shape and prominent camera housing don’t work well with standard magnetic power banks designed for conventional iPhones. Now a new solution is addressing that gap directly.
Better Mobile Xperience, commonly known as BMX, has unveiled the SolidSafe Duo, a 5,000mAh magnetic power bank engineered specifically for Apple’s first foldable iPhone. The accessory tackles the unique form factor problem by sizing itself to fit precisely within the edges of the iPhone Duo without overhang, ensuring the device remains balanced and usable even when the power bank is attached.
Design Built for the Foldable Form Factor
The SolidSafe Duo measures 77 x 88 x 11mm, making it significantly more compact than traditional power banks. This smaller footprint was achieved through the use of a custom semi-solid-state battery cell containing 5,000mAh of capacity. Unlike standard lithium-ion batteries, this cell uses less liquid electrolyte, allowing manufacturers to reduce overall dimensions without sacrificing charging speed or reliability. The aluminum CNC-machined casing provides both structural durability and enhanced heat dissipation during the charging process.
One of the standout features is the built-in 360-degree rotating ring stand. This addition transforms the power bank from a simple charging accessory into a versatile viewing stand. Users can prop up the iPhone Duo in portrait mode, landscape orientation, or even partially folded positions while maintaining the connection and continuing to charge. This flexibility appeals to anyone who frequently watches videos, participates in video calls, or wants to display content while the device charges.
Charging Capabilities and Display Features

The SolidSafe Duo supports wireless charging at speeds up to 15W, which provides reasonably fast replenishment for compatible devices. For those seeking quicker charging times, an attached USB-C lanyard cable enables up to 20W of wired charging power. The same cable also recharges the power bank itself at up to 15W, eliminating the need for separate charging accessories. A full-color TFT display on the power bank’s surface shows real-time information about remaining battery capacity and current charging wattage, so users always know how much power remains and at what speed their device is charging.
For shoppers considering iPhone accessories, this level of transparency proves invaluable. Rather than guessing whether the power bank has enough charge for an afternoon or commute, users get clear visual feedback that removes the uncertainty from portable charging decisions.
Availability and Pricing

The SolidSafe Duo carries a retail price of $79.99 in the United States and £79.99 in the United Kingdom. It is currently available directly through BMX’s official channels, with plans for Amazon availability in both markets beginning in October 2026. This dual availability ensures that shoppers have flexibility in where and how they purchase the accessory.
The introduction of the iPhone Duo represents a significant shift in smartphone design, and the accessory market is beginning to catch up with purpose-built solutions. Rather than forcing iPhone Duo owners to use accessories designed for different phone shapes, the SolidSafe Duo demonstrates how manufacturers are creating targeted products that acknowledge the unique needs of foldable device users.
What This Means for iPhone Duo Owners
If you’ve purchased an iPhone Duo or are considering doing so, having access to properly fitting accessories makes a meaningful difference in daily usability. The combination of thoughtful design, practical stand functionality, and genuine charging power means the SolidSafe Duo addresses real pain points rather than offering unnecessary features. The semi-solid-state battery technology also signals confidence in reliability and longevity, important qualities when investing in portable charging solutions.
As iPhone accessory ecosystems continue to expand and evolve, we can expect more specialized products designed around foldable phones. The SolidSafe Duo represents an early, well-considered entry into this growing category. For anyone with an iPhone Duo looking to extend battery life while maintaining a clean, integrated design, this power bank merits serious consideration.
