The battery weighs in at 4 3/4 ounces. The battery pack has one USB output port that outputs 5 VDC at 2 Amps. It is a smart USB port whose output current will never exceed the capacity of your smart device's current charging capability. The battery is extremely energy efficient and its performance is 10 percent or more above the standard performance of a normal designed external battery. This is because of the superior quality of the battery cells used and the advanced control circuitry within the battery.
During the testing the temperature of the battery pack never even exceeded ambient room temperature. To start your device charging you connect it with the proper cable and the battery pack charging starts automatically. To check the battery pack charge status you have to shake the battery and the LED ring lights up.
This product is outstanding and I rate it at 5 stars. If you are a business person or a student and have to depend on your tablet or smart phone for long periods of time without the ability to get to an AC power source then this is a good battery to own. This is good for those who travel a lot or camp out. Now you can watch your movies or listen to your music on those long airline flights. While this battery pack can put some charge into your tablets it is more ideal for use in recharging your smart phone.Read more ›
Continuing with their environmentally friendly packaging, battery came inside of a neatly packaged box which contained a battery itself, a manual (always very detailed), and accessory box with usb to micro-usb cable and a mesh draw-string storage bag for a battery and a cable. Now let me tell you about the size of this battery - its is SMALL!!! Weighting around 130g and with a size of 90mm by 45mm and thickness of 25mm - it will easily fit in a palm of your hand where you can make a fist hiding it inside. That's how compact it is. With a new rounded design and smooth edges, the hard plastic shell is lined with a soft touch rubbery finish. You get one micro-usb battery charging port (1A speed to charge the battery itself) and one full usb smart output port for any Android or Apple device. The output supports a maximum charging speed of up to 2A. In my quick test with OEM usb cable I confirmed a charging speed of 1.5A using my Note 2. The speed will obviously vary depending on the cable you use, so keep that in mind and use usb cables with thicker wires.Read more ›
Before leaving on a business trip last week, I plugged it into the wall using my phone OEM charger (5V/2A) as usual. Astro 2 was at approx. 40% charged. A few hours later, I unplugged it and noticed the LED status lights wouldn't illuminate to show current capacity despite the obligatory light tap. I figured the lights had died; they had always seemed a bit gimmicky anyway, so I didn't think much of it beyond planning to ask Anker for an exchange (which I did via email shortly thereafter).
A few hours later, I was on a flight to San Francisco when my phone's charge level got low. I plugged in the Astro 2, gave it a tap, and....nothing happened. The phone wouldn't start charging. I unplugged it. Then I noticed, the Astro 2 was starting to get warm. A few seconds after that, it got HOT. It appeared some short of a chemical reaction had started internally (the way alkaline batteries react if you try to short-circuit them). I put it in an air sickness bag, leaving the top open, and kept an eye on it. An hour later, it had cooled a bit but was still fairly warm.
On landing, I emailed Anker again and explained what happened. I also said I no longer wanted to exchange it for another one. Approx. 20 hours later, I got a response from them offering me a full refund. They also asked some additional questions including the Astro's serial#. When I picked it up (off the table in my hotel room where it had sat untouched and unplugged this entire time) to check the SN, the thing was still very warm! I was dumbfounded.Read more ›
