Anker 2nd Gen Astro3 12000mAh External Battery Charger with PowerIQ™ Technology

Anker 2nd Gen Astro3 12000mAh External Battery Charger with PowerIQ™ Technology

9901 Bluetooth speaker

Product Description

The all-new 2nd generation Anker® Astro3 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 12000mAh of juice, and featuring an energy efficiency rate 10% above previous generation Astros and many current standard alternatives, the new Astro3 charges the iPhone six times and large-capacity phones like the Galaxy S4 almost four times.

Double take.

Chic and minimalistic, the new Astro3 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 Astro3 is perfect for your next adventure, or just the daily grind.

For optimal use

- 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.
- 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 USB-charged devices. The iPod nano, Asus tablets (not include the Nexus 7), the LG G2 and some GPS and Bluetooth devices are not supported.

Customer FAQ

Q1.  Can I use USB cables othan 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.

Fantastic Charger... But...
I really do love this charger. Most efficiant charger I've owned (and I've owned several). I only have a couple of issues with it that I feel would make this the most solid charger on the market, hands down.1. on one end of the charger there should be a two pronged AC plug so I don't need to find a micro usb cord in order to plug it in. It could just plug into the wall.2. built in cables. The battery should come with both a silicon microusb and flash attachment that folds into the battery in addition to the three usb ports on the side. Some times I need to charge multiple devices, but most of the time I'm charging my phone. If i could attach an attachment that has micro usb charging cord that folds into the device, it would mean I didn't have to carry around multiple cords. 3. Charging passthrough to allow me to use the battery with myphone while the battery is plugged into a power source.

Thanks so much for the feedback.

These issues are all hotly debated by our customers when discussing what kind of changes they'd prefer with our batteries and if there's one thing we've learned it's very tricky to satisfy everyone! Apologies that you haven't found our design choices to your liking on this occasion but we do listen to all customer feedback and hopefully we'll get something on the shelves soon that is more to your taste!

charging cable
Hi Anker, I understand that a 28/24awg USB cable has a quicker charging ability then a 28awg cable. Is this true? If so, is the cable that came with my 2nd gen Astro3 12000mAh a 28/24awg cable?

Lower gauge is better but honestly doesn't matter that much as long as you get a quality cable and not a cheap one from the dollar store

oops!! The reason for the question is that I will be using a Anker® 14W Dual-Port Portable Foldable Outdoor Solar Charger. This will be riding on the rear of my bike most of the time and probably won't always be getting optimum sun exposure.

In fact our supplied USB cables are 28/22!

This means they're even better than 28/24.

Hello, I see that I can use this with the supplied USB cable, plugging it into my computer to charge the Anker. Can I also use the USB cable and plug it into the iPhone USB wall charger? Thank you in advance. -Matt

The Astro is compatible with most wall chargers but you'd have to ensure that the charger can output 5V/2A.

It may be the case that the iPhone charger won't be capable of this.

If you're having trouble charging the Astro3 then confirm that the wall charger you're using is capable of outputting 5V/2A, and please try on a computer's USB port as well.

If you're still experiencing problems then give our customer service guys a shout at support@ianker.com and they'll help you out further.

Quick charge
My greatest interest in a battery charger is how fast it can provide a partial boost to the charge in my iPhone 5S. I shoot video at music events and the battery frequently runs out before the show is over. The ability to extend the life of my phone by charging it for a short period of time once or twice during the show would be terrific. Other chargers claim to be able to charge faster by delivering the 2.1A needed for tablets to the iPhone which only requires 1A. Can you recommend one of your chargers that would best suit my needs? I assume it would use your newest technology.

Thanks. But, like I said, I'm more interested in how fast it charges - not how many full charges I'd get.

Any of our 2nd Gen Astro range would suit this job perfectly as they all have Power IQ. This means they'll provide optimum charging speed to your devices.

The decision you have to make is how much you want to compromise on capacity for size and weight. The Astro3 has 12,000mAh which will charge an iPhone 5S over 5 times but is a touch larger than the Astro2 (9,000mAh) and the Astro 6000 (6000mAh).

Using a 5.3V 2.0A Wall Charger
I understand the input for charging Astro 3 is 5V 2A.However, can i use a wall charger with 5.3V 2A output to charge the Astro 3? Will there is any negative effect on Astro 3 external battery?

Samsung Note3 & S5 wall chargers are 5.3V & 2.0A. Wondering if there will be any issue when using these to charge the anker astro 3 external battery.

.3V ..is not much to damage anything. The fluctation in voltage from even Anker's charger may hit 5.3 too. I wouldn't think twice about it if it were mine, but I'm sure Anker will have say to use their charger only to avoid damage, warranty and the rest. If it were 2V higher, ok then, but not .3.

Hi there,I'm really interested in this product, I wonder whether it is compatinble with both Nexus 4 and Nexus 5?Also, is there any chance of having a charger for this product as well (I mean for the wall socket to charge this)?Thank you for your help in advance!

It'll charge the Nexus 4 & 5 with no problem at all.

It doesn't actually come with a wall charger but we have a great selection of wall chargers ourselves. Our 40W 5 port charger is by far the most popular but you can look through the whole line if you search for 'wall charger' in the search box above!

I would suggest researching online if there are any anker products that are sold online, just a general rule of thumb is to look at the quality of the battery to see if it is the same quality that anker would make, and also if it is heavy. Replica batteries will be cheaply made and if they don't know what they're doing they'll be very light-weight batteries. But weight isn't everything, counterfeiters sometimes put weights on the inside to make the batteries seem heavier.
