5.0 out of 5 stars Works Great for iPhone 5 about 2 1/2 charges. YMMV October 25, 2012

By Abester

Color Name:black

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.

5.0 out of 5 stars Works great for our vacation January 10, 2012

By iPhone family

Color Name:black|Amazon Verified Purchase

Planning a trip to NYC, the wife and I both have iPhones (3GS & 4s). I knew up front we're going to need to charge them at some point and looked into getting this battery pack. It worked well for charge two phone while wondering around in the big apple. At night, usually after midnight I charge the battery pack and by 9 or so the next morning it was fully charged. I would wait til one phone reach 25% before charging it and then do the other. This allowed us to stay out longer enjoying the city and not have to worry about finding a place to plug in at.

5.0 out of 5 stars should your Mophie juice product not live up to the advertising October 15, 2012

By G. Nelson

Do NOT complain about poor performance of your Mophie product until you contact Mophie. I bought 2 Counterfeit Mophie products here at Amazon.

I complained to Mophie and found out the two products were FAKES!!!

All of the Mophie batteries I. Have purchased which were Real Mophie products have MET or EXCEEDED their advertising claims.

This is my first review Ever. I did it because I believe Mophie"s reputation should Not be hurt by criminals.

So don't do a negative review before you have the Mophie people Verify that your Mophie product is real or counterfeit.

Works as advertised. I've used it here and there as needed, but this last trip I forgot to bring my usb wall adapters and used the Mophie to charge my Iphone and Blackberry. Kept me running all week. On average, it charges my 3GS about 1% per minute and my wife's IPad2 about 1% every 4 minutes.

4.0 out of 5 stars Good power. March 1, 2012

By Dave

Color Name:Red|Amazon Verified Purchase

I really like the Mophie, and have recommended it to friends.

Aesthetically it looks very nice. This red version is beautiful, and the Product(red) idea is a great idea to support AIDS programs in Africa.

The only reason I'm giving 4 stars instead of 5 is that the device doesn't do "pass through", where you could charge it and power your phone at the same time.

I use it with both my Android smartphone and an iPad.

4.0 out of 5 stars Solid October 22, 2011

By Jim VINE™ VOICE

Color Name:black

It does what it says it does - stores power (for well over a week with almost no loss), built like a tank. The only downside I'd see is that, unlike what it says here in the ad copy, it does NOT charge at the same time that it recharges. If you're recharging your mophie, it won't charge your iPhone. So, that's a drag, and it cost them a star.

1.0 out of 5 stars Dissapointing October 15, 2011

By LCDR Joe Guido

Color Name:black

Purchased this power station hoping it would be an improvement over my Mophie iPhone battery case experiences (I have had to return 2 in less than 2 years due to failure). I charged this product fully out of the box, unplugged and let sit in my computer bag waiting for weekly travel. When I brought out on the plane 2 days later it only had one dot (bar) of 4 - although I had not used it to charge anything and it was never plugged in. Re-charged that night, rinse, repeat same problem next day on the plane. Sending back to manufacturer and looking for other brand. When Mophie works it works well, but after 3 product failures thinking they have quality issues.

I ordered this item and received a device that did not look as pictured. What I received was from the same manufacturer but appeared to be an older model.
