Increase Your iPhone's Battery Life

Double Your iPhone's Battery Life

The HP-1 has a powerful 1650mAh on-board backup battery which can nearly double the battery life of the iPhone 4/4S. The unique Smart Battery Protection circuit continuously monitors and optimizes the power performance of your iPhone, and an independent LED indicator keeps you informed of the remaining life of the secondary battery. The new "auto shut-off" feature will help preserve your battery life by switching off once the iPhone is fully charged.

Headphone Splitter

Headphone Amplifier & Splitter

The i.Fuzen HP-1 allows you to share your music with a friend by splitting the single headphone jack into two. The proprietary J-FET OP-AMP amplifier is powerful enough to drive two pairs of standard headphones or one pair of professional monitoring headphones while maintaining vacuum tube quality sound, making the HP-1 the ideal choice for audiophiles and music lovers alike. The new and improved amplifier will allow you to enjoy the headphone amplifier while your iPhone charges.

iTunes Sync

Unrestricted iTunes Sync

With full USB pass through capability, this case will allow you to sync flawlessly with iTunes without the need to remove the iPhone. The mini USB input also increases your options if you are in need of an emergency charge, but do not have access to a dock connector cable.

Innovative Design

Innovative Design

The i.Fuzen HP-1 takes advantage of the features and style of the iPhone 4/4S. The relatively sleek case accentuates the iPhone's distinctive lines while minimizing the increase in overall size. The HP-1 is available in white and black, allowing you to easily match the case to your iPhone.
