Question: Can someone please tell me how to charge the portable device itself? I want to know if/how I can charge this numerous times while in Europe.
Document: You need a portable charger. You know you do. I certainly did. The times my phone almost died and I needed to place a call, check a message etc.? Lifesaver. Good quality, charges my Iphone quickly, convenient, reliable, inexpensive. If you want a portable charger (and you do) go ahead and get this one. I keep it in my purse for when I need it.
However, there is no wall plug included so buyer beware.No way to tell throughout the day how charged it is, but indicator light will tell you when it's full. Haven't had a chance to fully deplete the battery yet, I don't know if there is an indicator for that.It doesn't get unreasonably hot when charging or during use. The cord is long, (maybe arms length) good if you want to have the charger in one pocket and your phone in another.
They QUICKLY offered a refund or exchange. I emailed them several times to get information about why my phone wouldnt charge but one time with this gizmo. Customer service even provided power calculations to show why my particular phone requires more power than what this charging device can provide. It was more an issue with my power-hungry phone.... not the Anker. Very please with their customer service. I will be keeping the charger anyway but will just manage charging of my phone differently.
This is the best thing ever. It has saved me numerous times, but now I have to get in the habit of charging it. Lol. Much less than any other device so TOTALLY worth it.
The Anker Astro mini 2600 is the find of our life. We use this product on our phones, ipods and my ereader. We are taking it with us to Europe and are no longer worried our electronics will die on us while out touring. Product support is fantastic, they contacted us to see if we had questions on the mini and to tell us about there guarantee. That is service above and beyond. I will look to them first in the future for products.
Not please with it! Not as great as I anticipated in charging on the go or holding it's own charge. Maybe not enough instructions arrived with it to know exactly what to expect, what it's capabilities are exactly. Ready to &#34;pitch it&#34; it ...wast eof my money as far as I am concerned.
If you have an IPhone or IPhone 5 - you need to have your own cord to make it work. I didn't know this because I didn't know what a "lightening cord" is. There's a cord included, which looks a lot like a "lightening cord", but it only works to charge the device, not connect the device to your phone.Also - when fully charged, it only charges your phone approx 1.2 times.
Do you know how many times people walk up to me and ask where to charge their phone? If you knew where I work, you'd answer, &#34;One heck of a lot,&#34; and you'd be correct. I reply, &#34;Nowhere,&#34; and laugh in their face. (Not really) But now, there's another option. This device is a phone charger that you can carry with you. Super small and convenient.
I use this for my Samsung Galaxy III. It will give a full charge and  still have juice left over (I don't know how much - I usually recharge after using it). This device is small enough to fit into a small purse, backpack or large pocket. It has saved my butt at work many times (I travel via public transit for work frequently and there is nowhere to plug in a phone, which I also need for work).
I bought this just for charging my Samsung GT-I5500L. I don't know how many times am I supposed to be able to charge my phone with this portable charger, but I noticed I can do it just one time, so if I don't recharge the charger it won't charge my phone to its fullest.
Answer: Charge it using your wall charger that came with your phone.
