The iPhone Duo launches this Friday, and BMX is already ahead with one of the first MagSafe battery packs made just for Apple’s new foldable. The BMX Duo 5000mAh Power Bank is designed to fit the Duo’s shape exactly, delivering wireless and wired charging without the awkward overhang common with standard MagSafe accessories.
Precision Fit, Clean Look
Because the iPhone Duo is shorter than traditional iPhone models, many existing MagSafe attachments either hang off its edge or don’t align well. BMX’s solution is a custom-sized 5,000 mAh cell shaped precisely to the folded dimensions of the Duo, allowing it to sit flush against the cover panel. It also maintains full compatibility with iPhone 12 through iPhone 18 when snapped on via MagSafe.
Charging Speeds, Display & Safety
The BMX Duo power bank delivers up to 15W wireless charging via MagSafe, and packs a built-in USB-C cable capable of 20W wired output. That means it can keep up both wirelessly and through a cable, depending on what you prefer or need.
On the exterior it features a full-color display showing the exact battery percentage and current charging wattage. It also includes a 360-degree rotating ring for ease of positioning. Safety is addressed via semi‐solid‐state cells that contain significantly less liquid electrolyte than conventional lithium-ion batteries—aiming to reduce fire risk.
The BMX Duo 5000mAh Power Bank is already on sale for $79.99, shipping now. As the iPhone Duo starts arriving in users’ hands, expect a surge of accessories built specifically for its new form factor.
This battery pack isn’t just a convenience—it’s a signal that the accessory market is evolving fast to support foldables. For users, it means better design, safety, and performance. For Apple and accessory makers, it underscores the importance of matching innovation in hardware with equal effort in supporting products. What’s worth keeping an eye on next: whether other battery makers prioritize form-factor fit and safety like BMX, and how quickly the Duo gets a full ecosystem of compatible accessories.
