Anker 2nd Gen Astro2 9000mAh External Battery Charger with PowerIQ™ Technology

78APIPADMNI2-02USA

Product Description

The all-new 2nd generation Anker® Astro2 recasts the possibilities of mobile power.

Compatibility maximized.

Not all charging ports are created equal. Standard ports only communicate effectively with particular devices, like Apple OR Android, often limiting their recharge rate. But with PowerIQ™ technology, each port intelligently identifies your device to speak its unique charging language. So plug in any brand or model and enjoy compatibility that doesn’t limit your charging speed.

Packed with power.

We figure, the more power, the better. Packed with 9000mAh of juice, and featuring an energy efficiency rate 10% above previous generation Astros and many current standard alternatives, the new Astro2 charges the iPhone four+ times and large-capacity phones like the Galaxy S4 almost three times.

Double take.

Chic and minimalistic, the new Astro2 may feel reserved at first. But, a friendly “shake” reveals its warm inner light to display the power level or begin your charge. Generous, cool, and delightfully intuitive, the new Astro2 is perfect for your next adventure, or just the daily grind.

For optimal use.

• Please use your device’s original cable or a third-party certified one (such as MFi).
• Compatible with all Apple and Android smartphones, tablets (including the Nexus 7) and other USB-charged devices. The iPod nano, iPod Classic, HP TouchPad, LG G2, Asus tablets and some GPS and Bluetooth devices are not supported.

Customer FAQ

Q1.  Can I use USB cables other than those provided with my Anker external battery?
To ensure complete safety and best performance, we strongly recommend using your device’s original cable, a third-party certified cable (such as MFI) or our included cable.
Q2.  Does it work with the new iPhone 5s, 5c?
Yes. But the Apple connector is not included. Please use your device's original cable.
Q3.  Anker external batteries' efficiency.
ALL external batteries lose power due to voltage conversion and circuit resistance.

Approximately 20% of Astro 2nd Generation external battery’s total capacity is consumed, including power lost from circuit heat and voltage conversion within the external battery (approximately 6%) and the charging cable and your device (approximately 14%). This efficiency rate is 15% higher than the industry average of 35%.

Older Astro batteries have lose approximately 30%.

According to industrial standards, all external batteries are labeled based on their raw cells capacity not efficiency. Like others, we are following this standard.
Q4.  How long will the battery lasts while not in use?
Generally, most of our external batteries' static power consumption is lower than 100uA, which will take between 3.5 and 20 years to drain the battery completely.

However, the chemicals within the li-ion battery will gradually become less active over prolonged periods without use. Most will die in 2 years of inactivity.

To extend your battery's life:
1. Charge and recharge it at least once every 3-4 months.
2. Do not over-charge or over-discharge it. It is best to keep it charged between 5%-95%.
Q5.  Can Anker external batteries be used for international travel?
Yes. Be sure the USB adapter you bring with is compatible with the voltage of the country you will be traveling to. An adapter's voltage input is usually printed on the adapter.
Q6.  Can external batteries be taken on board airplanes?
Yes, all Anker external batteries can legally and safely be taken on board airplanes. Here are the relevant requirements:

Quoted from Federal transportation security rules (Effective January 1, 2008):
Lithium ion batteries (a.k.a.: rechargeable lithium, lithium polymer, LIPO, secondary lithium).
-Passengers may carry consumer-sized lithium ion batteries [no more than 8 grams of equivalent lithium content or 100 watt hours (wh) per battery]. This size covers AA, AAA, 9-volt, cell phone, PDA, camera, camcorder, Gameboy, and standard laptop computer batteries.
-Passengers can also bring two (2) larger lithium ion batteries (more than 8 grams, up to 25 grams of equivalent lithium content per battery) in their carry-on. This size covers larger extended-life laptop batteries. Most consumer lithium ion batteries are below this size.

Anker's largest external battery is currently the Anker Pro 20000mAh (74 wh) which is lower than the above 100 wh limit.
Q7.  What can I do if I lose the provided accessories?
Please check to see if you have extras or contact us via email at support@ianker.com for help.

Problem with Anker 2nd gen
Buy a anker 2nd gen external battery at amazon three weeks ago. I used to recharge recharge my samsung tablet i5110 during long trips four times. Today i tried to recharge using usb cable but the led circle doesnt light on during recharge cycle , and i realize too that the battery are heating over the usually. Is it a normal behavior? Or the external battery is already dead? There is a support office at Brazil where I can fix the product or I have to deal with Amazon , because i m still in the warranty period, right?

I have a quick tip for anyone with this problem as I experienced something similar recently with my battery appearing to be completely dead, no lights etc.  basically when the battery is drained 100% it takes a lot of time and OOMPH to get it kick started. firstly make sure you are using a good USB plug adapter, at least 1.5A rated as this is what Anker recommend. Ideally use one of Ankers PowerIQ chargers.my battery was plugged in 24 hours and still seemed dead, but after 48 hours it was fully charged and good to go again.  I know it seems very slow, but I think there is a peculiar problem with Li-Ion technologies when the battery is 100% drained causing this kickstarter problem.i wonder if it is a similar issue to NiMH rechargeable cells - some chargers will not charge completely drained cells and others will due to the different charging technologies....?

Question
Can I leave the battery on charge all night, risking that it is 100% but it is under charging for a few hours? - See more at: http://www.ianker.com/product/79AN7903S-BA#sthash.4b6hLGXE.dpuf

Since the external battery has a dedicated port for charging and most likely is regulated. You should be fine leaving it at 100% under charging conditions. If you do it nightly though, then you might start to see wear on your battery.

You'll be absolutely fine charging the battery overnight. We just suggest that it isn't left sitting on charge for extended periods.

two questions
: 1)How many charge cycles are guaranteed? 2) If I rarely use the product and leave it unused for a long time, the battery will ruin?

The battery won't ruin, but it is good to use them about once a month. Li-Ion batteries are best when not stored at max charge and also not drained to low. They don't carry a battery "memory" like Ni cad's did where everyone was told to run it dead first. I have had my external for a long time, used it almost daily and it's held up very well.It will last as long, if not longer than a phone battery, which is charged daily, and used for years. I have had great luck with anker products on this vs other brands that have lasted only weeks.Plus they offer an 18 month warranty.

You shouldn't notice a real drop in performance before 500 cycles.

The chemicals within the li-ion battery will gradually become less active over prolonged periods without use. Most will die in 2 years of inactivity.
To extend your battery's life:
1. Charge and recharge it at least once every 2 months.
2. Do not over-charge or over-discharge it. It is best to keep it charged between 5%-95%.

The 2nd Gen Astro2 should have been supplied with a protective pouch when you purchased it, we don't really sell any other cases or covers.

If you didn't get this then please get in touch with our customer service guys a shout at support@ianker.com and let them know. They'll get you a replacement sent out.

Weird LED blinking on full charge
Hi Everyone,I hope I'm not asking something a bit too obvious here, but I've fully charged my Astro2 (Gen 2) 9000mAh battery and what I found is that the indicator light does not shut off while it's still plugged into the charger.  It appears to flash in a pattern that I'm not able to figure out, but it appears to flash a couple times slowly, then speed up in flashing, then suddenly end with a quick "blink" where the circle literally flashes for just .2-.3 of a second.  It first appeared random to me, but I can see a bit of re-occurrence.Is this suppose to happen with the models that have 2 smart ports?  Has anybody else experienced this?  Thank you!

This is actually a little unusual.

Does your Astro exhibit any other unusual behaviour? Do the LEDs not switch off regardless of how long you leave it charging?

Please give our customer service guys a shout at support@ianker.com, they'll be able to help you further.

Does the Anker® CG100 have a charging accessory? or you have to purchase extra battery.

The Anker® CG100 is a cabled mouse so you don't need to charge it.
