  • A must for those who travel that need portable power.
  • If you want to run or charge a small tablet then this will do it. Only issue was that the adapter for HP does not work properly. Once I made a power cord it worked perfectly

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 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.

Charging 12V 7A battery

Would it be possible, with a USB to Alligator Clip cable, to charge a 12V 7A battery with the Anker Astro Pro2 20000mAh?  Would you be able to estimate whether you'd be able to get a full charge or a partial charge?  I don' t know much about electrical design, but if the Anker has an output of 12V/4A, the answer is no.  Thanks for your time!

USb only outputs 5 V if you want 12 V you need to use the DC output Jack not usb 

on Ebay they sell dc output to aligator clip you need those kind for 12 V

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?

Replies(3) Collapse Report as spam Mar 15, 2015 at 3:42 PM

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.
