mophie iphone 5 jice pack helium

The form-hugging case makes your protected iPhone 5 easy to hold and use.

If you spend a significant amount of time on the go — be it traveling for business, or running errands and family members around town, you need your iPhone 5 to stay charged. And there's not always an outlet handy in a plane or at a store. The mophie juice pack helium solves the problem. This ultra-thin protective case features a built-in battery with enough power to keep your iPhone going for hours after the regular battery has run out. And its slender design makes it easy to slip into a pocket or purse.

Almost double your iPhone 5's battery life

Slip your iPhone 5 onto the juice pack helium's Lightning connector and close the case. It's now connected to a built-in rechargeable battery that can double your reserve of power. That's enough for 6 additional hours of talk or Internet use, or up to 30 more hours of audio playback. You can set the juice pack helium to keep your iPhone continuously charged, or with a button press recharge your iPhone quickly when you need it.

An all-access case

The juice pack helium has a USB charging cable that can connect to a computer or USB-compatible power adapter. And you can sync your iPhone through the helium's charging cable. Integrated pass-through buttons let you control volume, mute, and power on/off. You can also plug in your headphones through an opening the case.

What a fabulous invention!

Crutchfield Customer Review (What's this?)

This is a seriously helpful battery-life extender, which I find particularly useful because I travel so much. It's just great not to have to worry when the bar goes down to almost zero on my iPhone with no place to charge it (i.e. an airplane, a long train trip). With the Mophie Juice Pack Helium, this is never going to be a problem for me again.

Pros: Looks great.


The right solution at the right time

Crutchfield Customer Review (What's this?)

My IPhone battery was lasting only half a day. With this extra battery, I can travel with confidence that I don't need to have a charger handy for at least a day or two. I like the way it looks and the phone fits handily into the external case. It is easy to hold and fits nicely in my pocket. The instructions are clear as well. Since my Lighting Connector charger wasn't needed, I did find myself having to buy some extra micro-USB cords to use for charging in different locations, such as my car, but I can use it for other gadgets anyway. I was so pleased with the item I ended up buying one for my son's Galaxy IV phone as well since I often couldn't reach him because his battery would die on him while traveling. Now we're both well equipped and ready to travel with or without a charger handy.

Pros: Keeps IPhone charged for more than 24-36 hours. Lightweight and attractive. Simple to use.

Cons: Doesn't use Lightning plug so I had to buy extra micro cord to charge in my car.

Excellent product

Crutchfield Customer Review (What's this?)

I found out while on the road having no USB jack in the rental car posed spells recipe for disaster trying to talk and navigate using GPS watching the power steadily drain from my iPhone. Upon my return, I decided to purchase the mophie juice pack helium (recommendation from a colleague) and pleased it was a nice reprieve to thwart those times when power sources are scarce/nonexistent. The mophie case is roughly the same size of the Otterbox Commuter case so it's still sleek and easy to carry and appears to still provide some protection. And when I find times where the battery on the phone is depleted, it's nice to know that I can flip the switch on the mophie juice pack and it charges back to 100% (or close to it) so I can continue to use my iPhone until I have opportunity to plug into AC/USB port. The only slight complaint is the headphone jack requires their extension pigtail but I actually do prefer the location of the speakers migrated to the top faceing outwards. I would recommend to anyone considering the need for an additional power source to keep them up and running!

Pros: FAST SHIPPING! Thanks Crutchfield!!!

Great Product - extends phones life for continuous use. Quick Shipping.


Cons: None

Top tech must have

Written by: Scott A from Short Hills Nj on November 9, 2013

Just charge overnight. Leave it on at all times. I retain 100% power from 6:00am through 5:30pm. Power drops to about 65% around 10 pm. I am a heavy email, text and data user in a constant contact oriented business. Life expectancy approx 15 months.

Pros: Long life, charge overnight, leave turned on.

Cons: Hard to remove, bulky and adds weight to phone.

Product Research


Mophie Juice Pack Helium (for iPhone 5/5S): The Mophie Juice Pack Helium combines a protective case and rechargeable battery for your Apple iPhone 5/5S (not compatible with iPhone 5C). The Juice Pack Helium has a built-in rechargeable battery which extends the battery life of your iPhone 5/5S for hours. The Juice Pack Helium also provides an ultra-slim design with the complete protection of a hard shell case with protective rubberized backing. With the Juice Pack Helium, you'll be able to easily access all of your controls, microphone, camera speaker, and headphone jack (via headphone extension cable). It also has acoustic sound enhancing speaker ports for a richer, fuller sound quality.

Note: You will need to remove your iPhone 5/5S device from the Mophie Juice Pack Helium in order to connect your iPhone 5/5S with an Apple certified product with a Lightning dock connector. You will also need to remove your iPhone 5/5S from the Juice Pack Helium to connect your iPhone 5/5S to a home audio or car stereo component which allows iPhone playback through its USB port.

Extended Battery Life: Since it is designed to extend the battery life of your iPhone 5/5S by up to 80%, the Mophie Juice Pack Helium is the ultimate iPhone 5/5S battery case for travel or business. The Juice Pack Helium is great for when your iPhone 5/5S is drained of power or you simply one to extend its battery. When the iPhone 5/5S is connected to the Juice Pack Helium, a battery symbol will appear on the screen and you will hear a chirp from the iPhone 5/5S; this indicates that the iPhone 5/5S is charging and/or using the power from the Juice Pack Helium rather than from the iPhone 5/5S itself.

  • Talk Time: up to additional 6 hours on 3G
  • Internet Use: up to additional 6 hours on 3G or LTE, and up to additional 7 hours on WiFi
  • Audio Playback: up to 30 hours
  • Video Playback: up to 7 hours
Note: If your iPhone 5/5S is drained of power, the Juice Pack Helium will first charge your iPhone 5/5S. If your iPhone 5/5S is fully charged, the Juice Pack Helium will act as your primary battery and no power will be lost from the iPhone internal battery until the Juice Pack Helium is depleted

Rechargeable Battery: The Mophie Juice Pack Helium features a rechargeable lithium-polymer battery rated at 1500mAh. The Mophie Juice Pack Helium battery can easily be recharged by connecting the Juice Pack Helium to a power source using the included micro-USB cable. The USB cable can be plugged in to your computer or any "Works with iPhone" wall-plug style power source with USB output. You can either charge the Juice Pack Helium with the iPhone 5/5S inserted or charge them separately. The Juice Pack Helium comes charged and ready to go, but after the initial use, normal charging will take only 2 to 3 hours for maximum power.

Note: The Juice Pack Helium is rechargeable for over 500 full cycles. So, you can charge your juice pack 10% of the way 10x before it counts as a complete cycle. After 500 cycles, its fully charged capacity will be less than 75% of the capacity when it's new.

Standby Mode: The integrated power switch allows you to put the Juice Pack Helium in standby mode, so you only use the battery when you need it. In standby mode, the Juice Pack Helium still allows charge and sync capabilities through the micro-USB port and still offers the complete protection of a case.

4 LEDs: Four LEDs on the bottom of the smart battery case keep tabs on how much power is left in the Juice Pack Helium battery. The LEDs also keep you updated on the Juice Pack Helium charging status when it's plugged in. The LEDs located on the back of the device will blink when charging. As the Juice Pack Helium becomes more charged, the LEDs will indicate how full it is, but one LED will remain blinking until completely full. To check the battery status of the Juice Pack Helium, press the button located on the bottom of the case. When pressed, the LED lights will illuminate for several seconds. Four LEDs means that the Juice Pack Helium is fully charged, and one LED means that it is almost empty.

Protection Circuitry: The Mophie Juice Pack Helium features built-in short circuit, over-charge, and temperature protection.
