Using myPower for iPhone 4
2. How does myPower for iPhone 4 work?
 

You can use myPower for iPhone 4 to power your iPhone 4 or iPhone 4S, or to charge your iPhone 4 or iPhone 4S while connected to external power. When powering iPhone 4 or iPhone 4S, myPower for iPhone 4 will bypass the iPhone battery to power a connected iPhone 4 or iPhone 4S, thus extending the overall life of the iPhone 4 or iPhone 4S battery. The Tekkeon battery will not charge iPhone 4 or iPhone 4S unless connected to an external power source.

myPower for iPhone 4 is charged in two ways: by connecting to a USB power adapter, or to a USB port on a computer. The included USB cable is used to charge the device. If you are using an iPhone 4/4S-compliant USB power adapter, you also may charge your iPhone 4 or iPhone 4S at the same time by inserting the iPhone 4 or iPhone 4S in the battery case while connected to an external power source.

As a bonus feature, myPower for iPhone 4 doubles as a dock to sync iPhone 4 or iPhone 4S to your computer when connected via the USB cable. In this case, myPower for iPhone 4 will both sync and charge iPhone 4 or iPhone 4S.

   
3. How is myPower for iPhone 4 different than other models on the market?
 

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.

Increases Comfort
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.

Minimal Footprint
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.

   
4. What is eSwap?
 

myPower for iPhone 4 is designed with the innovative eSwap™ technology (patent pending), 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 the extra hours virtually limitless.

The myPower for iPhone 4 battery case includes an ultra slim 1200 mAh battery pack. Tekkeon offers the ultra slim battery packs as optional modules.


5. What do I need to use myPower for iPhone 4?
  You need your iPhone 4 or iPhone 4S and a power source (either the computer or an iPhone 4/4S-compatible power adapter).

6.

How do I charge myPower for iPhone 4?

 

You can charge myPower for iPhone 4 in two ways: by connecting to external power via a USB power adapter, or by connecting to a computer USB port.

   
7. How long does it take to charge myPower for iPhone 4?
  An empty myPower for iPhone 4 will charge in about 3 hours using an iPhone 4/4S-compliant power adapter. Both empty batteries can be charged in about 6 hours.

8. Can I sync my iPhone 4 or iPhone 4S without removing it from myPower for iPhone 4?
  Yes, you can sync your iPhone 4 or iPhone 4S while in the battery case using the included micro USB cable.
   
9. How will I know how much power is left in the battery?
  When your iPhone 4 or iPhone 4S is docked into the battery case, the dual-color battery level indicator on the bottom of myPower for iPhone 4 will indicate the remaining capacity of the external battery.
   
10. Will the battery case scratch the glass back of my iPhone?
 

In response to Apple's concern that the back of the iPhone 4 potentially may be scratched if dust or other elements were to get between a case and the iPhone back, Tekkeon has included its myGuard protector set with myPower for iPhone 4. This will prevent any scratches on the back when the iPhone is in or out of our battery case.

   
11. What should I do when I receive the following message after placing my iPhone 4 or iPhone 4S into the battery case and plugging the battery case into a wall outlet: "Charging is not supported by this accessory"?
 

This message means the iPhone is not receiving enough power from the power source. You must use an Apple iPod/iPhone/iPad-certified USB charger as stated in our User Guide.

   
12. What should I do when I receive the following message after placing my iPhone 4 or iPhone 4S into the battery case: "This accessory is not optimized for this iPhone"?
 

Perform a hard reset of your iPhone 4 or iPhone 4S by holding the Sleep/Wake and Home buttons at the same time until the Apple logo appears. This type of reset will not result in the loss of any of your data stored your iPhone 4 or iPhone 4S.
