Customer Reviews

Impedimentus "Impedimentus"
  • GREAT BATERY, EXCELLENT CUSTOMER SERVICE
  • This is a high quality product. The battery is in a brushed metal case and has a professional look to it. The fact that the battery offers three output voltages, 12V, 16V, 19V as well as a USB charging port is a definite plus. These batteries seem to have a very high efficiency (battery rating to actual power expended before discharge). I purchased six of the Anker Astro Pro2 20000mAh batteries to provide backup/travel power to several different laptop computers and they have performed very well.I was extremely pleased with Anker's customer service. I had an issue with one of the batteries some months after purchase. Anker was SUPER FAST in responding to the issue and providing a replacement battery under warranty with absolutely no cost to me. The customer service rep kept me updated on the progress of my return/replace request in a very timely manner. Anker values its customers and provides excellent customer service. If only other companies provided such outstanding customer service while offering a quality product. I highly recommend this battery.

  • Good Size, Weight, Capacity and Overall Value
  • This battery has a huge capacity. Since almost everything uses USB today, this pretty much replaces having a big 12 volt car type battery pack. It isn't too big or heavy so I have it with me and can recharge cell phone, tablet, netbook and even laptop. It recharges one item at a time though. I tried using a USB hub but it wouldn't work.

Q8.  What's the output efficiency of the Astro Pro2 20000mAh external battery?
The efficiency of this battery is around 70%-80%. The internal circuit board is 92% efficient, accounting for power lost through circuit heat and voltage conversion, which is up to 5% above the industry average. Energy is also lost within the charging cable and the device being charged (approximately 15-20%). Additionally, the efficiency can be affected by the cable length and the age of the device being charged.
Q9.  Can the Astro Pro2 20000mAh external battery charge other devices while it is being charged?
Yes.

When the battery is charging your devices, the LED indicator will remain unlit when charging other device. When the battery is being charged, the lights will flash repeatedly one by one to indicate progress. The LED indicator will all remain lit when the Astro Pro2 is fully charged.
Q12.  How long will the charge in the Astro Pro2 20000mAh external battery last without being used?
Generally, the Astro Pro2 20000mAh external battery's 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, please discharge and recharge it at least once every 4 months.
Q13.  Can the Astro Pro2 20000mAh external battery be used for international travel?
Yes. However, you may need to use an universal convert to work with the power adapter since the provided power plug is special for the country it was originally shipped to.
Q14.  Can the Astro Pro2 20000mAh external battery be taken on board airplanes?
Yes, all Anker external batteries including the Astro Pro2 20000mAh external battery 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.

This external battery (Anker's largest external battery) is with 74 wh which is lower than the above 100 wh limit.
Q15.  What should I do if the Astro Pro2 20000mAh external battery can not be charged?
a. Check that the AC adapter is connected securely.

Usually the answer is that any charger of sufficient capacity can be used to charge an external battery, but for this one Anker is very specific about using the one that came with the battery. To avoid any risks or warranty issues I agree with MikeC that it is best to contact Anker direct at support@ianker.com

Compatible Toshiba Portégé Z30

Would this battery be compatible with my Toshiba Portégé Z30-A-1ES? I was looking for the specs of my connector tip and I think it's the same for all Z30 models, so see example below.

Toshiba Portege Z30-A-12U also Z30-A-13W

AC input voltage: 100 ~ 240V 50~ 60Hz

DC output voltage:19V

DC output current: 2.37A

Power:45W

Connector Size: 5.5X2.5MM

I notice that the dimensions of the tip match the tip above that is stated to be compatible with the ACER Aspire 1600, 5610:

5.50 x 2.50 - ACER Aspire 1600, 5610
I looked up specs for the ACER conector tips and got the below:

19V 3.42A FOR ACER PA-1600-

Feature ˆ Input : AC, 100-240V, 50-60HZ ˆ Output : DC, 19V, 3.42A, 65W ˆ Connecter size : interior diameter: 1.7 mm external diameter: 5.5 mm

 

The only difference that I can see is that the Wattage is 65W whereas the Z30 likes a 45W. I really don't know much about electronics. If you could advise that would be great!!

It will work just fine.

You won't even need an adapter, the Pro's standard output will go straight into your laptop.

No. The Astro Pro2 line requires 110/220v through its power adapter to chage. The solar panels will charge any Anker battery *except* for the Astro Pro2 line.

The 1st Gen Astro Pro2's max output is 19V/3A so if this is higher than your laptop's original charger then it'll work just fine. You can confirm your laptop's charge level by checking the original charger for its output in V/A.

It is also worth remembering that you might also need an adapter to turn the 5.5*2.5mm output of the Pro2 into your Laptop's required size.

Using the Anker Astro Pro 12v output

Hi, I'm trying to use the 12 volt output of my Astro Pro 20000Ah battery to drive a GPS Re-radiating antenna, which uses a car 'cigar-type' plug. I've used the supplied lead with the 4.0mm x 1.7mm DC plug, attached to a car 12V accessory socket. It works initially, but after about a minute the LCD goes blank and the voltage switches off. I guess this maybe because the battery thinks the device isn't drawing enough current? I've tried adding a 100 ohm resistor across the output (so that it draws 100mA), but it still switches off. How can I make the thing stay powered up?

cheers henry

It sounds like it may be low power draw. Try adding a higher resistance and see if that helps.

I have an Anker 79AN20L-SA.  I need a connector for my Dell Inspiron 13 (7347) and I need a connector that is 4.5mm on the outside and 3.5 on the inside.

Do you have one?

If the connector you need wasn't included with the Astro then unfortunately we don't manufacture it.

The output of the DC cable is 5.5*2.5mm so you should be able to find an adapter to accept that size then go into your laptop.

Specification

Some comments (not really for your FAQ section!):

As you know, airlines are sensitive about carrying batteries.  Their limit is 101Wh.  Why don't you include the fact that the Astro Pro 2 is rated at 74Wh in the main specification (where the product photo is) so that we can print that page and travel with it in case we're asked.  The "74Wh" is buried in amongst the FAQ.

Thanks for the advice that the Astro Pro 2 output connector is 5.5x2.5mm.  Why don't you add that to the specification area as well.  You don't have a connector for the Microsoft Surface Pro and potential customers will want to buy or make cables for this, and potentially other 12V devices with non-standard dc connectors.

The Astro Pro 2 is a brilliant product for the 12V Surface Pro 3.  I'm a bit concerned that your current products all seem to be targeted at the 5V market and the Astro Pro 2 is a "previous gen" product.  Makes it look like you're going to make it obsolete.  With laptop and tablet technology converging, I think you should keep the Astro Pro 2 in your line-up!

Pity, I think that information for airline security is important for everyone.  It's an expensive item to lose just because some security person is worried.  A specification linked to a product photo would help that.  Please review!

Additional information...
 

I have a unique need for "mobile UPS" type backup battery. Your device appears to be what I need. I have a Lenovo q190 installed in my car that acts as a music server. It's not necessarily a laptop, since it doesn't have an internal battery or monitor. However, it does use a laptop style power supply and is currently powered using an universal DC power supply, which came with multiple tips and supports multiple voltages.  My questions: 1) Can the Pro2 be charged by the DC charger and simultaneously power the PC thus acting like a "mobile UPS."(Note: the Pro2 would power the PC whenever the car isn't being driven and solve the car battery drainage issues I have.) 2) Anything else I need to consider before purchasing?

First off, pass-though charging is NOT recommended by Anker as it negatively affects battery life.
Secondly, the Astro Pro2's have a 110/220v, 18.5v output charger, unless you get into also wiring in a DC/AC converter, you won't be able to power the Astro Pro2.
Thirdly, while you could set the battery up so that it does what you need, the Astro Pro2 will not start a charging cycle in its own, you need to press an activation button to start its charging process.

You might be much better off setting up a separate, fused relay from the car's battery instead, if the Lenovo shuts off it's charging cycle once it's at 100% and doeesn't turn on until 80 - 90% again, you ought not seriously affect your car battery's life. Would require a bit more wiring and effort to properly route the wires through the car, but I think it's a more stable and automatically-enabled solution that throwing some good money at a battery that you will not get your best value on using it with pass-though charging all the time.

Thanks for your interest!

1) Yes
2) Make sure you have the right input tip for your Lenovo. The output of the Pro2 is 5.5*2.5mm, you'll need an adapter to accept that and go into your system if the input isn't already this size.
