Product Description

Daytrip? Subway commute? Backpacking? Whatever you're up to, break away from the outlet and bring your power with you.

Palm-sized power plant.
Although it can't produce power, sometimes is seems like it. Sporting enough juice to deliver six or more charges to most phones and 80% of a charge to tablets, there's enough power to go around.

Shockingly portable.
Bar shaped and 22mm thin, this stowable unit will fit into almost anything - handbags, briefcases, jeans pockets or even just your palm - so you can pull it out and jolt your gear back to life at any moments notice.

Full speed ahead.
The dual-port (2.1A + 1A) design allows you to charge any two USB-powered devices simultaneously. With a total current output of 2.1A, or more than four time faster than a standard computer USB port, charge up fast and enjoy your gear more.

For optimal use.
• For simultaneous, max-speed charging of your Astro and other devices, check out Anker's new line of 18W / 3.6A car and home adapters.
• Compatible with all Apple and Android smartphones, tablets and other 5V input USB-charged devices. The iPod nano and some GPS and Bluetooth devices are not supported.
• The included Micro USB cable is compatible with the Samsung Galaxy S5, Note 3 and other Micro USB 3.0 devices. To connect, insert the cable's Micro USB tip into the larger of the two connection ports on your device.

5.0 out of 5 stars Amazing value for money. 3 Feb. 2014
Verified Purchase
Incredibly impressed with this item.

When I purchased it, the device came fully charged. As with most devices with built in batteries, I wanted to completely discharge it so that I could completely charge it again and make sure the battery was well-conditioned before I took it travelling.
Was very suprised how much effort it was to actually discharge it. Connected it up to my HTC One, which was tethering internet at the time (usually drains the battery on the phone quickly) whilst connected up to my Nexus 7 watching Netflix over Wi-Fi.
Over an hour of watching later I had barely made a dent in how much power was still stored in the Anker, which was still nearly fully charged.
Pretty much used it to charge every device in my house that had a USB device before I drained it.

Will be taking it to Thailand for three weeks and I know it's going to be a life saver considering how much I use my Nexus and Phone as a GPS / mapping device to get around.

Can't fault it.

5.0 out of 5 stars Great Idea 26 Jun. 2014
Verified Purchase
My Iphone 5's battery is shameful at best. It lasts at the very most half a day, I have it plugged in all day at work.

The reason I bought this product was to have in my golf bag, as I use my GPS is on there. I no longer have to suffer the annoyance of having no GPS anymore.

I'm afraid my boss has defaced the product already, but it still works fine.

It's a bit bigger than I expected it to be, but it is in no way big.

Highly recommended :-)

5.0 out of 5 stars Large and in charge 28 Mar. 2014
This is a beast of a battery. 2 outputs and one micro USB input. Has a handy torch activated by pressing and holding down the small power button. Battery indicator too that has various States of blue led to show remaining power. Did I mention this thing is large? You will not be able to fit this into your coat or jeans pocket. It's a backpack bound boy and would recommend a longer USB lead if you want to snake it through a hole to have in your pocket or just out of the way really.

This is a brilliant piece of kit. It saved my hubby's life the other night when he was using an iPad at the European elections.

5.0 out of 5 stars Invaluable 20 Aug. 2014
Verified Purchase
Great product with so many mobile devices it can charge my phone, my blue tooth device, the 3D glasses for my TV or a PS3 controller if needed. The phone gets about 3 full charges at least so it's become pretty much invaluable to me. A great device for the modern world.

This charger is really good. Ive had this over a year and it still works really well and the charge lasts a while too.
Great for on the go. Yes - Its bulky kinda heavy but perfect for your bag so long as you keep it waterproofed. The light is also handy.

5.0 out of 5 stars Very useful item indeed 12 Oct. 2014

Verified Purchase
Very useful item indeed!
If you are travelling a lot like me, you should get this.
Doesn't come with a connector but fits my iphone 5 connector nicely.
Able to charge my iphone 5s up to 4 times. However it charges itself very slowly.

This product is great if you need to keep having battery power even without plug in the wall charger. The best you can charge 2 devices at the same time.
Maybe the drawback, is weight and size. But it provides me with what I require...
