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 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.

When the phone’s in the red, press the juice pack case’s status button for 3 seconds and let the case to 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. 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.

Why aren’t the LEDs blinking while my juice pack case is charging?After you begin charging the juice pack case, 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 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?

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 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?All Wi-Fi and LTE functions on the Galaxy S8 and Galaxy S8 Plus are unaffected by the juice pack case. However, the juice pack case may interfere with NFC performance.

Excellent quality great customer service &warranty
I am on my third new phone in as many years and this is my third mophie - I can't get a new phone without this product - I run so many apps that the phone battery gets sucked down quickly but all I need to do is press the button and I get another few hours. The build quality is great and I know first hand that this company stand behind their product - I dropped my phone and broke my first mophie - they replaced it within days! And then my second juice pack stopped charging (after 2 years) and they replaced that one... Love this company - and especially like that the magnetized the case so I can use qi charging - this is the perfect device!!
