Leveraging a connector that has previously been exclusive to Apple products, Chinese developer Beaver Electronics has announced the Quarter Super PowerBank ($59), a battery pack built with a MagSafe 2 port for recharging. Clad in Mac-matching silver aluminum, Quarter is designed to work with both Apple’s MacBook wall chargers and the Quarter Car Adapter ($16), a silver metallic and mirrored charger with a MagSafe connector. This Car Adapter is designed solely for Quarter, not for MacBooks.

The 5,000mAh battery claims 2.1-Amp output that’s safe for iPad, iPhone, and iPod use with a full-sized USB port, while itself recharging at up to 3-Amp speeds in only 45 minutes — up to 10X faster than typical batteries, Beaver says — or via a 1-Amp micro-USB input in 7 hours. Beaver notes that after only 15 minutes of MagSafe recharging, Quarter will have enough power to refuel an iPhone 5s. Rather than pressing a button to see how much battery power remains, you just shake the battery once, triggering four blue LED lights…

Physical samples sent by Beaver look and feel impressively solid, though Apple’s track record of denying third-party developers access to MagSafe connectors suggests that Quarter will be a very limited edition.

The company is offering $39 pre-orders through Australian crowdfunding site Pozible, and having already exceeded its US$10,000 goal, promises that the first 1,000 Quarter units will be available starting November 10.
