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.

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 the lifesaver!!!!
I am a heavy user of my phone. Before I would have to run around with a charger & cable, now all I do is press a button to double my phone run time without charging. This gets me through the day and keeps me productive all day.

Why you need this design
Not thinking when I bought this the 1st time I simply bought this to cover the phone I have dropped it numerous of times and sometimes I even forgot that is a charger as well this has saved me so many times as I own my own business I am truly thrilled with the performance so I'd bought a second one as a gift

Great Product
I've always had issues with battery life, no more! It's slim and fits into a pocket nicely. Only downside is the opening for the headphone jack. It should have been slightly larger to accommodate a regular size jack without have to buy a special plug adaptor or to remove the case for use.

Hasselfree replacement!
I was able to replace my juicepack within the warranty without any hassle. Got replacement within a week and used same packaging to mail back previous juice pack. Love this product because it seemlessly keeps my Samsing Note 8 longer than ever. Only drawback for me is that I cannot do wireless charging. It must be plugged for both juice pack and phone to be recharged simultaneously.
