Customer Questions
Can I use the juice pack case to charge my phone without stopping what I’m doing?

You bet! After you install your phone in the juice pack case, press the status button on the back of the case for 3 seconds to start charging your phone without having to stop at a wireless charging base or at a wall outlet. If you want to stop charging the phone and save some battery for later, just press the status button again for 3 seconds.

What wireless chargers will my juice pack case work with?

The mophie juice pack case is compatible with mophie charge stream pads and the mophie wireless charging base. It will also wirelessly charge from any Qi-compatible wireless charger, and is compatible with other wireless charging technologies, such as those used at coffee houses, on airline flights, in furniture products with wireless charging, and in consumer vehicles that support wireless charging.

Will the juice pack battery fast charge from mophie charge stream pads and the mophie wireless charging base?

No, the juice pack battery will charge at standard Qi charging speeds, not at fast charging speeds.

How do I wirelessly charge my juice pack case?

Simply place the juice pack case on any Qi-compatible charger. (mophie charge force products will automatically align the juice pack case for a proper charge.) Wireless charging will automatically begin when the case is aligned on the charger. If your phone is inside of the case, the juice pack case and phone will charge together.

Will Samsung Adaptive Fast Charging work on my phone when I’m charging the phone and juice pack case together from the Samsung Adaptive Fast Charging wall charger?

Yep. Your phone will Fast Charge from the Samsung Adaptive Fast Charging wall charger while it’s inside the juice pack case.

How does the extra battery work?

When you slide your phone into the juice pack case, a connector at the base of the case plugs into the port at the bottom of the phone. Flip the standby switch on the back of the case from red to green to start charging your phone. After using up all the power in the juice pack case, just recharge it with the included micro USB cable for more on-the-go power.

Does the juice pack case block the speaker, microphone, camera, or any other ports?

Of course not. In fact, the juice pack case is designed to act as a virtual speaker box! Sound is redirected from the bottom of the phone to the front, resulting in a richer, fuller sound quality.

Does the juice pack case interfere with my phone’s antenna reception?

Not a chance.

Why aren’t the LEDs blinking while my juice pack case is charging?

After connecting the juice pack case to a power source, the LED status indicators will start blinking to indicate charging. The lights will turn off after 30 seconds allowing for a good night’s rest. Remember to check the status indicator before you disconnect. When all four LEDs are lit, your juice pack case is fully charged.

What is the best method for charging my phone using the juice pack case?

Assuming that your phone and juice pack case are both fully charged, we recommend waiting until your phone has 20% battery left. When the phone’s in the red, press the juice pack case’s status button for 2 seconds and let the case do the heavy lifting. The phone requires more power to charge past 80%, so if you want to get the greatest battery boost from the juice pack case, we suggest putting it back into standby mode until your phone battery is low again. This isn’t the end-all-be-all, but we like it.

Is the juice pack case’s wireless charging compatible with Samsung’s Fast Charge Wireless Charging Pad?

Although the juice pack case will wirelessly charge from a Samsung Fast Charge Wireless Charging Pad, it will charge at standard wireless charging speeds, not at 1.4x Fast Charging speeds.

How do I charge my juice pack case when I’m on the go?

After using up all the power in the juice pack case, connect it to a power source using the cable included with your phone. You can plug the cable into the wall adapter included with your phone or any power source with a USB out. You do not need to remove your phone from the juice pack case to charge. In fact, leaving your phone in the juice pack case while charging will charge both your phone and the case together.
