update: Anker contacted me and offered a free power bank that can be charged using 5v USB so i can use it to charge IPAD. Surprise that their small power bank can offer 2A to charge IPAD. Great customer support and excellent products.
Only downside is that you CAN'T charge it via USB AT ALL. All the other batteries like this I've had charged over USB. Used this one once before I lost the power adapter, so now I have to go and spend another $30+ on another power adapter. They say it's to charge it faster, which is fair enough, but to not have ANY USB charging at all is a disappointment.
I took one unit to Cuba last winter and since we forgot our voltage converter the Anker provided a charge for our Ipad and iphone using the USB ports. A great product.
The second issue raised by others here was the fact the Sena headsets would not charge. My enquiry to Anker customer service confirmed my suspicions that the Sena's draw so little power that the battery cannot detect and goes to sleep. My simple solution is to always charge my Sena's along with my camera and that works perfectly!
Nice robust unit. Now that I have it I find many uses for it like using it at home with my IPad if it is running low on my deck etc.
One more thing I love about the Anker 2nd Gen Astro Pro2 is that I can FINALLY charge my PS Vita without having to use/buy the Sony proprietary battery pack! I would recommend this product to anyone who wants to good quality, excellent value item.
The only downside to this product is that it's a bit big and heavy to carry around but may I remind you, your are also getting at least 2 - 3 times more battery power than a smaller more compact battery pack!

One of the best products I've purchased on Amazon. The best priced product and delivers every time I'm in need. The charge does down very slowly if not used over a period of time. Read morePublished 3 months ago by Prasanna Rathna Raja

Works great, huge battery and an actual display that shows how much battery life is amazing. Also having the ability to switch from 6v to 12v is very nice!Published 3 months ago by Wyatt Earp
Very solidly built and holds a lot of juice. A bit bigger than I expected by a top notch unit all the same. Read morePublished 6 months ago by Blinkd
I give 3 stars because the unit is built solidly and performs its function. The missing stars are due to the lack of information surrounding the multivoltage port. Read morePublished 7 months ago by Chris Kiss
