Tekkeon Unveils myPower™ for iPhone® 4, Rechargeable Battery Case with eSwap™ Replaceable Battery Module


Tustin, CA--November 2, 2010--Leveraging its battery expertise, Tekkeon today unveils its ultra slim rechargeable battery case for iPhone® 4, designed with Tekkeon’s unique eSwap™ technology that delivers virtually endless power. myPower™ for iPhone 4 includes a swappable battery pack that can be exchanged on the go to let users talk, rock, view, share, and stay connected longer. This tiny, sleek battery case not only provides extra power on the go, it protects iPhone 4 from everyday wear and tear and acts as a dock for automatic syncing via a high-speed micro USB 2.0 interface.

Several innovative features distinguish myPower for iPhone 4:

Swappable Battery Module
myPower for iPhone 4 features Tekkeon’s new innovative eSwap™ technology, in which the battery is housed in a separate module that can be exchanged with a fresh battery module while on the go. This enables users to carry extra, fully-charged battery packs, making its additional hours virtually limitless. The battery case comes with the Ultra Slim 1200 mAh battery pack, with extra battery packs--both the Ultra Slim battery pack and the Ultra Power 2200 mAh battery pack--available as optional modules.

Preserves iPhone 4 Battery
Equipped with a replaceable efficient lithium polymer battery pack, myPower for iPhone 4 preserves the iPhone battery by bypassing the battery and directly powering (rather than charging) iPhone 4. When plugged into a USB power adapter or computer USB port, myPower for iPhone 4 will simultaneously charge the connected iPhone 4 battery.

Highly Efficient Design Provides Maximum Power
Designed with intelligent circuitry, myPower for iPhone 4 provides an unheard of 95% efficiency which means the condensed lithium polymer battery provides maximum power output without adding substantial weight or size to iPhone 4. Inherent with this advanced battery technology are all the key battery safety features, including built-in protection from over current, overcharging, over discharging, overheating, and short circuiting.

myPower for iPhone 4, depending on the battery module, almost doubles or more than doubles the iPhone 4 battery:

Increases Comfort
With a sleek contour that softens the iPhone 4 edges, and a slip-proof, soft touch finish, myPower for iPhone 4 makes iPhone 4 more comfortable to hold.

Minimal Footprint
At only 1.84 oz (51.5 g) and with a minimalist design that elegantly wraps iPhone 4, myPower for iPhone 4 is almost undetectable.

Protection from Wear and Tear
myPower for iPhone 4 doubles as a protective case; its hard shell interior and raised edges, along with the included myGuard protectors for the front and back of iPhone 4, provide a high level of protection to iPhone 4. Because it encloses the side and back of iPhone 4, the battery case enhances iPhone 4 reception by acting as a bumper.

“With our long history of providing innovative battery products that fully support the mobile lifestyle, Tekkeon is excited to take our battery products to the next level with our innovative eSwap technology,” says Jerry Yang, president of Tekkeon. “Because iPhone users can swap battery packs on the go, myPower for iPhone 4 ensures that users can literally never be without power.”

myPower for iPhone 4 features easy access to all iPhone 4 features, including the camera and flash. The battery case includes an on/off switch to conserve power when the battery is not needed and a bright, dual-color capacity indicator that shows remaining power at a glance.

myPower for iPhone 4 comes in three fun colors: Soft Touch Black, Soft Touch Red, and Soft Touch White. The suggested retail prices for myPower for iPhone 4 and the optional spare batteries are:

myPower for iPhone: $79.95
