Frequent Questions

  • 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 perfect 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.
    What wireless chargers will my juice pack case work with?
    The mophie juice pack case is compatible with all mophie charge force products. 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.
    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 does the extra battery work?
    When you slide your [Bowser] phone into the juice pack case, a connector at the base of the case plugs into the port at the bottom of the phone. Press the status button on the back of the case for 3 seconds to start charging your phone. After using up all the power in the juice pack case, just recharge it for more on-the-go power. If you want to stop charging the phone, press the status button again for 3 seconds.
    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 you can wirelessly charge it from any Qi-compatible charger, or you can connect it to the wall adapter included with your phone or any power source with a USB out using the cable included with your phone. 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 — Priority+ charging ensures that the phone will charge first, before the juice pack case begins to recharge.
    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.
  • Why aren’t the LEDs blinking while my juice pack case is charging?
    After you begin charging the juice pack case, the LED status indicator 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 take your juice pack case. When all four LEDs are lit, your juice pack case is fully charged.
    How many charge cycles can I get out of my juice pack case? Or, in other words, how long will the juice pack case last?
    You can recharge your juice pack case for over 500 full cycles. A full cycle is when you recharge the case from 0% to 100%. Partial cycles, like charging from 25% to 100%, will not count as a full cycle until all the partials equal 100%.

    After 500 full cycles, the battery in the juice pack case may provide less than 75% of its original capacity. This is normal for any product with a lithium polymer battery.
    Does the juice pack case block my phone’s fingerprint sensor?
    No, but we recommend that you reprogram your phone’s fingerprint sensor after you’ve installed the phone in the juice pack case.
    Does the juice pack case block the speaker, microphone, camera, S Pen 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?
    All Wi-Fi and LTE functions on the [Bowser] phone are unaffected by the juice pack case. However, the juice pack case may interfere with NFC performance.

Rated 4 out of 5 by from Very happy with mine I've had it for a while now, and am very happy with it. The only issues I have are with the cover to the S-Pen. It is a bit of a pain to open and get the pen out. Unlike others reviews, I have had no issue using the s-pen. To wirelessly charge, it needs to be at a very specific angle with my Samsung wireless charging pads. (the case throws off the alignment or something) I put a tiny piece of velcro on the bottom of the phone and the bottom edge of the charger to make sure it stays in the correct position to charge. (I keep my charging pad at the elevated angle for better viewing while it sits on my desk) It would be great if I didn't have to do that. Otherwise, it's been super handy. I've even used the case to charge a friends Note 8. ;)

Rated 4 out of 5 by from My Mophie I bought 2 of these.. one for me and one for my son. I like the concept but I don't like the design. I have samsung wireless chargers. And a charger for my car that grabs my phone.... the edges of the mophie makes it impossible to charge on either one of them. The only wireless charger I can use is the one that lets you lay your phone flat on it... This is my only complaint about the mophie. I love the fact that it keeps my phone charged and I can play for a long time on it.

Rated 4 out of 5 by from Wish it would work with wireless charging The ONLY downfall I can find is it won't work with the wireless charging in my vehicle
