The mophie juice pack extends the battery life of your Android™ phone for hours and provides a comfortable ergonomic design with the protection of a hard shell case.
Here’s a rundown of why the juice pack air is so fantastic:
1. (Take a breath) Ergonomic, form-fitting, fully protective ultra-impact-resistant case-and-battery-in-one for your Android™ phone.
2. Integrated power switch allows you to put the juice pack into standby mode. Only use the battery when you need it. In standby mode (red), the juice pack still allows charge and sync capabilities through the micro-USB port and offers the complete protection of a case.
3. Uses breakthrough rechargeable lithium polymer battery. (Much safer than those troublesome lithium-Ion batteries).
4. State-of-the-art battery technology extends the life of your Android™ phone for hours… and you can even recharge it while it’s still connected to the phone! This battery rocks.
5. Track battery power status at a glance with an integrated 4-light LED status indicator which shows charging mode and current battery life. Know before you go!
6. It’s the included USB micro cable connection that allows you to charge and sync your phone while refilling your juice pack at the same time. Really, you don’t ever have to disconnect the juice pack, though it’s a snap when you do.
7. Rechargeable for over 500 cycles. (These are FULL cycles. Partial cycles don’t count as full. So, you can charge your juice pack 10% of the way ten times before you get to a complete cycle. Don’t be afraid to top it off.)
8. Smart battery technology actually instructs the phone to drain out the juice pack first. When you’re done with the juice pack you can pull it off and still have a fully charged phone.
9. The juice pack offers complete protection from top to bottom. No more choosing between protection and power.
10. Built-in short circuit, over-charge and temperature protection. Safety First!
Though the juice pack for Samsung Galaxy SIII comes with a standard micro USB connector, this battery is intended solely for use with the Galaxy SIII phone.
Charging your phone using the juice pack
If your phone is drained of power or if you want to extend the battery life of your phone, simply slide the phone into the juice pack. If your phone is drained of power, the juice pack will first charge your phone. If your phone is fully charged, the juice pack will act as your primary battery and no power will be lost from the phone’s internal battery until the juice pack is depleted. So you keep on talkin’, rockin’, surfin’ and sendin’!
Sync with your computer without removing the juice pack
While connected to the juice pack, you can still sync your phone with a computer. Simply connect the included micro USB cable from the juice pack to the computer and sync your phone the same as if it was directly connected.
How many charge cycles do you get in the juice pack?
The juice pack is rechargeable for over 500 cycles (These are full cycles. Partial cycles don’t count as full. So, you can charge your juice pack 10% of the way 10 times before it counts as a complete cycle.) Don’t be afraid to top it off!
Can I sync my phone while the juice pack is still connected?
You can charge and sync your phone without removing it from its juice pack via the included micro USB cable.
Will I always receive double the battery life with my juice pack?
We cannot guarantee that you will receive double the battery life. The amount of additional battery you will receive depends on a variety of factors that are different for every user.
Does the juice pack block the speaker, microphone or cameras?
Of course not! The juice pack features a speaker chamber with acoustic routing to keep speakerphone audio clear.
Does the juice pack interfere with antenna reception?
Not a chance.
How does it work?
The mophie juice pack® has a rechargeable lithium battery inside. When you slide your phone into the case, a connector at the base plugs into the micro USB port at the bottom of your S III. Flip the standby switch on the back from red to green to start charging your phone. After using up all the power in the juice pack, just recharge it with the included micro USB cable for more on-the-go power. It’s as easy as that.
How do I charge the mophie juice pack®?
Simply connect the juice pack to a USB power source, like a wall charger, car charger, or your computer, with the included micro USB cable. You can charge the juice pack while it’s on or off your phone. If you charge with the case on, it will also charge your S III!
Does the juice pack interfere with S Beam or NFC (Near Field Communication)?
Not a chance. Our case will not interfere with your phone’s NFC or S Beam capability. You can still share photos, websites, contacts, etc. with the juice pack on your phone.
What colors are available?
This juice pack is available with a soft-touch black matte finish or a beautiful, high gloss white with metallic silver accents.
How do I get the most battery power out of the juice pack?
Correctly using the standby switch will give you the best battery boost. The S III uses power to be on a constant charge, so only charging when you need power is the best way to use the case. We recommend waiting to charge until your phone is down to 20% or less. Limited use of your phone while charging will also increase the percentage of battery the juice pack will give you.
How many charge cycles do you get out of the juice pack? Or, in other words, how long will the case last?
The juice pack is rechargeable for over 500 full cycles. A full cycle is when the case is charged from 0% to 100%. Partial cycles, like charging from 25% to 100%, will not count as a full cycle until all of the partials equal 100%. After 500 cycles, the battery in the juice pack will be less than 75% of the original capacity. This is normal for any product with a lithium battery.
Will I always receive double the battery life with the juice pack?
It is not guaranteed that you will receive double the battery life. The amount of additional battery you will receive from the case depends on a variety of factors that are different for every user.
Will the juice pack charge any other Android™ phones?
No. This juice pack is only compatible with the Samsung Galaxy S III. You can, however, use one of our powerstations to charge virtually any other smart phone!
