Mophie debuts modular Hold Force case for iPhone 7 & 7 Plus, but no headphone jack

The case itself is available in nine different color combinations, including ones that are mostly see-through. All of them include magnetic plates in the back, which allow the modular components to pop on and off.

After buying the case, owners have a choice of three accessories. The first, the Wallet, simply adds two card pockets. The Folio improves on this, adding a third pocket and relocating cards to the inside of a lid.

The most significant accessory may be the Powerstation Plus Mini, a 4,000 milliamp-hour battery pack. This adds up to 12 hours of extra battery life, and includes a switch-tip connector, letting users switch between Lightning and micro USB.

What the cases do not have, however, is a headphone jack. Other battery cases adding a 3.5-millimeter input to the iPhone 7 are in the works, but none are yet available.

Mophie is selling the case for $39.95, and the Wallet and Folio for $19.95 each. The Powerstation Plus Mini is $59.95. If people buy accessories alongside the case, though, the prices of the Wallet and the Folio drop to $9.95, and the Powerstation slides to $39.95.
