One feature that I am concerned about with this product is the inability to "lock" it. What I mean by this is, if you throw this sucker into a bag/purse/pocket - the light switch will inadvertently be turned on. I am constantly noticing the flashlight on and then having to switch it off. The end result is that you will have a dead battery (or severely drained) that won't be there when you need it most. This unit would be ideal stored somewhere will the light button will not be accidentally pushed.
So, developers/engineers - the gauntlet has been thrown down. Your mission, should you choose to accept is: The flashlight is a cool feature; keep it! But give users the ability to securely lock this unit in the off position.
Note: This review is after owning the product for 1 day. I will update it accordingly if I find it necessary.
Prior to purchasing this portable battery, I had ordered the "Anker Astro Mini 3000mAh." I found that this small charger was at first quite efficient in charging my devices. Though, shortly after the charger no longer maintained stability in charging. The charger would disconnect every so often while charging the devices. After complaining to Amazon, I received a (hassle-free) full refund of the product.
Back to this product: I'm fully satisfied with the "Anker® Astro 5600mAh." This portable charger is the best "bang for the buck."
With my devices (an HTC ONE S, T-Mobile myTouch Q, and a Samsung Galaxy S II) I was able to charge the HTC ONE S from 30% to 91%, the T-Mobile myTouch Q from 3% to 72%, and the Samsung Galaxy S II from 35% to 82%.
Note: that these tests were performed immediately after receiving the product. I did not charge the portable charger at all, but rather still used it from the 3 bars it came with.
- Included Micro USB cable works as expected
- Rapid charging of devices. Though keep in mind the charging times will vary per the device.
- Battery light indicator display to show how much juice the charger has left
- Simplistic design
- Easy to use
- Inadequate flashlight
The flashlight wasn't the reason I purchased this product. Thus, I won't even remove a star for that.
===UPDATE (January 27, 2014)===
After additional usage, here are my added thoughts:
I still stand by this product. It's still superb and efficient for such a small device.
- Built in flashlight lasts quite a while
- Somewhat rugged
- Included bag
Flashlight: Although the built in flashlight is inadequate (as aforementioned), the light does last quite a while. Thus, it is better than nothing.
Rugged: I have lent my portable charger to my siblings, and they have dropped it several times with the device having no damage. Thus, I think it's safe to say that this portable charger is somewhat rugged. Note, though when I typically use the portable charger I always keep it in the included bag (for added protection).
I hope this helps a consumer make a portable battery purchase. If you found this review to be helpful, please let me know :).
So here to update my previous review on the Anker Astro 5600mAh battery, after having the original unit fail from minimal to heavy use, it was still covered under the 18-month Anker warranty (16 months in)! Upon reading my original review here on Amazon, I was contacted by Anker's very friendly customer service department (several weeks after the posted review), within minutes of being on the phone with a representative, they had a new Astro battery on its way! I'm very happy with the outcome of the situation, Anker responded quickly, their representatives were very polite and you could actually understand them! I enjoy using/buying Anker products from their solar panels to their Bluetooth speakers and everything in between, I would definitely recommend this battery in particular, it's helped in many situations! (Also I am not being paid to write this review, I just really enjoy writing thorough reviews to help others out). Thanks!
