Mophie Juice Pack Powerstation Duo: All day charger for mobile gadgets

I bought this USB charging unit because I have a lousy sense of direction. I get lost in buildings and in cities, even ones I’m familiar with. My iPhone’s GPS map is a godsend. I use it when I’m driving, walking, and taking public transportation.

When I was in Tokyo in June, I brought along a small Android phone installed with a local data SIM card. I used the phone as a wireless hotspot for my iPhone, and appreciated having access to the online map to guide me from my hotel to the subway station, and to attractions like the Tsukiji fish market and Kabuki-Cho. It was also nice to call home using Skype, and to post Instagram photos. The only problem was that the batteries on the Android phone and iPhone drained after a few hours, forcing me to ask people, chikatetsu wa doko desu ka? in badly-accented Japanese, to find the nearest subway station.

On my next overseas trip a couple of months later, I brought along a 6000 mAh Mophie Juice Pack Powerstation Duo. It’s a beefy battery pack that has two USB charging ports. I kept it in my daypack and my family and I used it to charge our phones while we were walking around London and Paris. It was like having a portable wall outlet, because it never came close to running out of juice, despite nearly constant use. It’s bulky — about as wide and tall as an iPhone 4 and nearly three times as thick (see photo below). I wouldn’t carry it in my pants pocket, but it isn’t a problem in a jacket pocket or bag.

If you want all-day smartphone Internet connectivity, the Mophie Powerstation Duo is what you need.

6000 mAh Mophie Juice Pack Powerstation Duo $100

  1. You know you can get the Anker Astro 5e for $50 on amazon. twice the capacity as this.
    Anker astro slim3 has the same capacity as this, is much smaller, and is $36Both are well reviewed; not to mention battle tested by us nerds playing Ingress. 

  2. Another vote for the Anker Astro.  5600mAh at less than half the price of the Morphie pack.  I’ve owned my Anker for 2 years now, and it’s still going strong.  Only 1 USB port, but just buy two battery packs if you require 2 USB ports.  ~12000mAh of power for less than $100!

  3.  Another vote for Anker products, in general – they’re top quality products.  Check out the reviews on Amazon.  I have a Astro Pro Multivoltage (2x USB at 2A total) plus 9V or 12V.  

    If you’re looking for an iPhone-sized external battery and only need to charge USB devices, can I suggest the Anker 2nd Gen Astro3?  12000mAh with a 4A(!) output on three USB ports.  Half the price of the Mobie Juicepack and twice the capacity. 

    Or, if you insist on spending $100, how about the crazily huge Anker Astro Pro2.  20,000mAh  – yes, you can charge up your laptop.

  4. Not going to get into Apple Maps vs Google, but there are plenty of Android phones with removable batteries and external chargers, so you can just pop a new battery in when you need to (I carry several when I travel), rather than hauling around a clumsy phone-and-charger nunchuk.

  5. 18000 mAh for $100 through the limeade kickstarter.  They shipped out to people already and they work awesome.
