  • Note how the battery resets/Add reset button
  • I bought this battery to run the digital setting circles, the Bluetooth unit that communicates with my tablet as well as the mirror fans and secondary dew heater on my Dobsonian telescope. I haven't had a chance to use the unit in the field yet, but testing on the various systems shows everything working. The reason I didn't give the battery five stars is the email requesting a review came barely a week after receiving the Pro2 and the terrible instructions that came with the unit.While testing the wiring on the scope after making changes to accept the battery (installing a barrel receptacle), a couple of wires touched causing a short, and the battery died. No output, no lights, no nothing. There is no reset button on the unit, and I did not want to take anything apart. So what to do?Well, it turns out that the battery resets when plugged into its wall charger, and I'm very glad there is a circuit protecting the Pro2. As plugging into the charger was the only remaining action to take before returning the unit, I'm happy it worked. Why this couldn't have been noted anywhere, is a mystery (A college grad no doubt wrote the instructions). A reset on the battery would be a nice improvement as plugging into the the wall charger is not practical for a device meant to be used without having to plug into the wall.

  • Lack of connector types.
  • I finally bit the bullet and bought this because it's smaller and more portable than my old eX-powerII which didn't have a connector for both my work HP laptop and my personal Asus laptop. The down side is the connectors that come with it seem to have one that fits the HP but it doesn't charge it. At first I thought it was because it was because the Anker battery is 19V out at 3A and the HP power adapter is 19V and 3.5A. BUT! i tried the connector from my eX-power II and it worked! So now i'm using the cable from my eX-power instead of what came with the Anker. So like others, I believe there is a lack of connector type support. Otherwise, so far so good.

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 external batteries with a capacity lower than 27027mAh (100 Watt Hours) can legally and safely be taken on board airplanes. To calculate a battery's capacity in Watt Hours: (Battery Capacity(mAh)*3.7)/1000.

Anker Astro Pro2

I have a brand new Astro Pro 2. I charged it for 8 hours. I went to use it to charge my iphone 5. I used my usb cable from the battery to my phone. Everytime I plugged it into my phone, I turned on the battery. It would go off within 5 seconds each time. What could be wrong with the way I am using it?

Sorry if this sounds obvious but was the phone's battery in a condition where it actually needed more juice? If the phone's battery is down and the Pro 2 isn't boosting it, then time to check in with a tech at support@ianker.com

Unfortunately not.

If you can find an alternative solar panel that outputs 15V/1.3A then it'll work just fine though.

Compatible with solar panels?

Can the Astro Pro2 be charged via solar panel (specifically a Powerfilm foldable panel)? What is the size of the input jack? What cables or adaptors would be needed?

From my research, it appears that the Astro Pro2 can be charged via solar panel (provided the input voltage/amperage is sufficient (15-19V/1.3A), and provided you have the right connectors.  The input jack appears to be a standard 5.5mm barrel jack. Thus, to charge from a Powerfilm panel you would start with PF's RA-1 male-12V-car-charger adaptor, then add a BixPower (or other manufacturer) female-12V-car-charger-to-male 5.5mm-barrel-connector adaptor, which would plug into the Astro Pro2.

No, it has its own power adapter that requires 110v/220v input. The Astro Pro2 line are the only battereies that cannot use solar chargers.

It has a 5.5*2.1mm input, and your solar charger will need to output 15V/1.2A to charge the Astro properly.

This is not a battery

There's a nuclear core in this thing - the act of plugging it into the wall is to distract you from the actual power source. This is no mere battery, it's a project that escaped from Tesla's lab! 

 

Seriously though, I've used this to keep a netbook, iPad Air2 and a Note 10.1 alive on vacation for a week of light use and only depleted it to 40% on a single charge. Airport security has stopped me twice to get a better look at it - but I think that resulted in some additional sales for Anker.

If you are in business and you HAVE to stay powered - this is a weapon you need to have in your arsenal. As a traveller who needs his tech to stay up this the first thing that hits my carry on.

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!!

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
