myPower for iPhone 4 is different in several distinct ways:
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.
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 or iPhone 4S. When plugged into a USB power adapter or computer USB port, myPower for iPhone 4 will simultaneously charge the connected iPhone 4 or iPhone 4S 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 or iPhone 4S. 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.
Complete Protection from Wear and Tear
myPower for iPhone 4 offers complete protection, from its hard shell interior and raised edges to the included myGuard protectors for both the front and back of iPhone 4 or iPhone 4S. The myGuard protectors are included to prevent dust or other elements from scratching the surface of the iPhone 4 or iPhone 4S.
With a sleek contour that softens the iPhone 4 or iPhone 4S edges, and a slip-proof, soft touch finish, myPower for iPhone 4 makes iPhone 4 or iPhone 4S more comfortable to hold.
At only 1.82 ounces and with a minimalist design that elegantly wraps iPhone 4 or iPhone 4S, myPower for iPhone 4 is almost undetectable.
