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.

juice pack is rated 2.9 out of 5 by 7.
Rated 5 out of 5 by from Great product Got this for Christmas and it's great. Also got the other products from mophie. I got the vent,the desk mount and power station. They all work for me and I do have battery life all day long . I have it charge before work and when I come home from work I have about 85%. This does charge fast and does what it does. So far no issues yet at all. I'm glade I got this for Christmas. Great product, thanks mophie .

Rated 5 out of 5 by from Outstanding ! This is wht a battery case should be if you have a note 8 then this is # one must have item !

Rated 4 out of 5 by from Good case but you'll lose NFC reading ie. Yubikey This is a great external battery case. Adds some bulk, but keeps the phone looking sleek. Samsung Pay MST still works with the case still on and the NFC also works as well. However, I have a Yubikey, and tapping NFC devices on the Note8 with the case on will not register. You have to remove the case for it to register. When you install the case, the headphone jack also becomes inaccessible because now the port is about an inch into the case. You will need to purchase an extension/adapter since the hole for the headphone jack is about 5mm wide. Magnetic case with the Charge Force vent mount is an awesome combo. I used the iMagnet mount before having the Mophie and the magnet is a LOT stronger. However, I did do some McGyver-ing and used my old iMagnet base with the Charge Force mount since I prefer the suction mount over a vent mount. Overall, I am totally happy with this case. I do wish it was a little less bulky, but I get it: it has an external battery. Oh, the external battery will not fully charge your Note8. It will increase your phone battery by about 50%. I went from 30% to 80% in about 2 hours. Also, it does not quick charge the Note8 on the wire or via wireless. Having quick charge would've made this good product great! Maybe v2.0?

Rated 3 out of 5 by from Works okay First and foremost the case will only charge your phone about 50%. So keep that in mind. Secondly, this case is very heavy, which with an extra battery I figured that would be the case. The biggest issues I have with this case is that it collects dirt in The headphone jack easily! And in the case itself. I also find that the speakers for sound quality is terrible. Which the note 8 sound without the case is great. This case adds quite a bit of bulk and is a bit slippery, this is a pop socket fix. Overall this is a great case, my phone is my life line for my job and daily life. So having the added battery allows me to work more with ease! I also enjoy that the s-pen is put away a bit. Because every note I've ever owned I have lost the s-pen.

Rated 1 out of 5 by from Mophie removed my review of Note 8 Case It’s huge HUGE! Makes your phone feel like a brick. Doesn’t charge the phone fully only about 64%. The spen has a cover that is a pain to open. Check Amazon for real reviews. I’m sure this one will be taken down. Ps I own about 10 mophie cases and this one by far is the worst they have made.

Rated 1 out of 5 by from So pen issue This case is creating a dead spot on my note 8 with my s pen. Right at the bottom of the screen where keyboard would be. Take phone out of the case works fine put it back in and dead spot is there. Can't write in dead spot area with s pen. Also if you type with s pen this case makes it difficult as dead spot is right where keyboard is. They clearly did not fully test this with this phone. Waiting on response from them.

Rated 1 out of 5 by from Stopped Working After 2 Weeks! My much anticipated Samsung Galaxy Note 8 Mophie juice pack case finally arrived after a month of waiting for Mophie to develop this new model of battery case. But after about 2 weeks of use, my phone no longer can charge its internal battery via wireless nor wired USB-C port. I emailed Mophie 2 times over 7 days ago and no reply yet, but they do have more in stock now, so today I was able to request a warranty replacement at a cost of $6.41 to cover shipping to Florida and taxes. I will update my review once I receive the replacement case and have tested it for a short while. I am a huge fan of Mophie and have several of their juice pack cases on my family's other phones, as well as several of their wireless charging pads in my vehicles and around my home. The fit of the case seems to be spot on, has a good feel in my large hands, the camera is not impeded, nor is the fingerprint scanner, so all design aspects seems great, as expected from Mophie. Hopefully this malfunction is not a common defect, and my next case works as well as this case did for the 1st 2 weeks. It's a pain to have to always use the juice pack to slow charge my phone, and once the juice pack is full, it does not charge my phone battery. So I have to take the phone out of the Mophie case and plug it in directly or lay it on a wireless charge pad, then it fast charges. If the replacement case works I will happily update this review.
