  • Good Battery Pack.
  • It's a good little battery that doubles the battery life of my Dell 3000 2 in 1. It didn't have the adapter I needed to plug it into my Dell, but I thought that would be the case going in to it. I purchased a set of connecters later and it works. It doesn't charge my Dell, but the laptop battery doesn't discharge while the Anker is plugged in. This is a little disappointing because this Dell has one of the lowest power requirements out there. I haven't tried it on another laptop yet, but it is a pretty good device. I do wish there was an additional USB port and a way to charge the battery by USB.

  • I didn't role the dice and went with the reviews and am happy I did
  • This thing is truly something. I can give my lenovo laptop about 2-3 full charges. It has a very study construction and then indicator lights....indicate! These power packs are a tough field because it is still not mainstream technology so you probably aren't guaranteed a certain standard of quality. I didn't role the dice and went with the reviews and am happy I did.

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.

Laptop connector tips for Lenovo U330p

Hi,

I have the Anker Astro Pro2. I am purchasing a new laptop and have decided on the Lenovo U330p laptop. It has a completely different power connector than the tips that came with my Anker external battery. Do you have a connector tip for the Lenovo U330p, or might there possibly be one coming out soon?

Thanks,

Mina Mojtahedi

If the adapter you need was not included in the package then unfortunately we do not manufacture it. You should be able to find one on the internet than can accept the Pro's 5.5*2.1mm barrel plug output though.

If the correct adapter is not included then unfortunately we do not manufacture it. You should be able to find one that accepts the 5.5*2.1mm output of the Pro's DC cable.

Mr Keith Horgan

Hi,

I read the Astro Pro2 20000mAh Multi-Voltage External Battery is rated at 74 Wh. I am looking to power a device that draws up to 2A at 12V DC (24W), although that is just what the main power adapter is rated at.

The device's manual says the maximum power it consumes is 20W and the current consumed is actually 0.75A (therefore 9W at 12 V DC)

Am I correct in thinking this battery would therefore deliver a useful charge for a little over 8 hours, or am I making an error in working this out ?

Many thanks,

It's difficult to be sure since the power draw of your device looks variable.

If you could give our customer service guys a shout at support@ianker.com and provide as much information as you can then they'll be able to get you a good idea of how long you can expect to power the device.

It certainly has the power to do so. Charging the battery while having it power your laptop is not a good idea for battery life, Anker recommends against it. But the Astro Pro2 has tons of power, I love mine.

This depends on the laptop.

If the 19V/3A output of the Pro2 is higher than the output of your laptop's original charger then it should work just fine!

If you need any further help or confirmation then do please get in touch with our customer service guys at support@ianker.com, they'll be able to help you further.

I use the Anker E series all the time to charge my DSLRs, why not take a look at them rather than a multi-voltage unit?  I have one DSLR that eats batteries like rabbits eat lettuce and I have had great luck with the Anker Astro E7 for shoots that go all day and into the night.

If the correct tip you need isn't included with the 1st Gen Pro2 then unfortunately we don't manufacture it.

The output size of the 1st Gen's DC cable is 5.5*2.5mm though and you should be able to find a tip that fits!
