5.0 out of 5 stars Works Great for iPhone 5 about 2 1/2 charges. YMMV, October 25, 2012
This review is from: Mophie Powerstation 4000mAh 2.1A External Battery Charger for iPad, iPhone, iPod touch, DROID, HTC and BlackBerry - Travel Charger - Retail Packaging -Black (Wireless Phone Accessory)
I bought my Mophie Powerstation (4000mAh capacity) direct from Mophie in early October 2012. Just for grins I decided to give it a workout to see how it performs before I needed it for a trip. Here's what I did...

I let my iPhone 5 battery deplete to 20% remaining as I normally don't let it get near completely dead. I attached a recently charged Mophie Powerstation that was 'topped off' the day before testing began. Using my wrist watch I observed and logged percentage charge and elapsed time. I left the iPhone 5 powered ON during charging but with the screen blanked most of the time, peeking every few minutes to observe it's progress. I did this test three times without recharging the Mophie Powerstation.

From a 20% charge remaining as displayed on the iPhone 5 screen.

Attempt #1 from 20% :

to 30% charge = 10 minutes elapsed time
to 40% charge = 20 minutes elapsed time
to 50% charge = 30 minutes elapsed time
to 60% charge = 40 minutes elapsed time
to 70% charge = 50 minutes elapsed time
to 80% charge = 60 minutes elapsed time
to 90% charge = 70 minutes elapsed time
to 95% charge = 80 minutes elapsed time

I didn't try to charge the iPhone beyond 95% as it was taking progressively longer to top it off. As you can see, the rate of charge is pretty linear up to ~90% and it charges at a rate of about 1% per minute.

I achieved the same exact result on Attempt #2, again starting with the iPhone 5 with just 20% charge remaining, and the Mophie Powerstation NOT being recharged after Attempt #1. I then tried charging the iPhone 5 for the third time without recharging the Mophie.

From a 20% charge remaining as displayed on the iPhone 5 screen.

Attempt #3 from 20% :

to 30% charge = 10 minutes elapsed time
to 40% charge = 20 minutes elapsed time
to 50% charge = 30 minutes elapsed time
to 58% charge = 45 minutes elapsed time
to 58% charge = >60 minutes elapsed time

The Mophie started running out of steam about midway through the third attempt but still had enough juice to get me over 50% charged.

Your mileage may vary depending on how you deplete and recharge your iPhone but for me, having over two full charges is more than sufficient in this relatively compact battery.

You might be confusing the Mophie Power Station battery pack for the Juice Pack that doubles as a case with embedded battery. The Power Station is just a USB battery pack that works with all iPhones, iPads, iPods, and several brands of devices. The Power Station does indeed work wonderfully with the iPhone 5.

I just got a juicepack powerstation today but whenever I connect to my iPhone 5, it will charge for maybe a minute, then just stops. I'm sure the juicepack is fully charged. Am I doing something wrong?

It should just work. Recharge the Powerstation overnight with your iPhone charger. Deplete the iPhone battery to maybe 50% or lower. Attach the Powerstation charger to the iPhone and turn ON the Powerstation. That's it. If it doesn't appear to be working correctly, contact Mophie.

Received a mophie powerstation for Christmas. I was told is was a booster for charging both an Ipad andIphone at the same time. However I am very confused as to how this will work with each device
