Customer Reviews

  • Battery lasts a good long time
  • Battery lasts a good long time. I can even charge my cell phone and use it to run a Hansen espinner (12V) at the same time. I ran this about 1.5 weeks with at least one hour per day usage off 1 charge.My only gripe is it comes with a small carrying bag too small to fit all the accessories. Since I didn't even notice it came with a bag and it does not hinder functionality I find it only a minor wish to have.

  • Compact, powerful, versatile.
  • Great versatility -- USB power (high amp) plus driving 12v-19v items (laptops, medical equipment, all sorts of things).Compact and (relatively) light weight. Used it for a recent major trip that included multiple 12+ flights. Not all the flights had on-plane power, but this allowed us to use all our electronics without fear of running out.My only complaint (and not enough to dock them a "star") is that the status lights are strangely bright. They could be much, much dimmer and it would be better. I even tried coloring in the lights with a Sharpie, just to tone them down a bit. Not much improvement, though.

  • Anker Astro Pro2 20000mAh Multi-Voltage
  • This was a HS graduation gift for my grandson. He absolutely loves it.So far it works great and holds it charge well. He indicated that very little power was used to charge his items.

  • Excellent Battery for Surface Pro 3
  • It works really well to charge my Surface Pro 3. However the DC port will not accept all aftermarket charge cables. However the BMOUO DC12V cable works well. It has lots of capacity. Only disadvantage it that it does not come with a pouch as others have noted. The small pouch is for the accessories. I have been back and forth with their customer service and they are sending me a pouch that is supposed to it.The lights which show the remaining power are bright and work well. I tried the RAVPower Xtreme but could not see the LED display.

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.

Q11.  What do the LEDs indicate when the Astro Pro2 20000mAh external battery is charging itself or other devices?
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.

What does it way on your power supply next to "Output?" The most common models in the Dell 7000 series have an output of 19.5 Volts and 3.3 Amps, so I would think as long as you had it set for 19 Volts, you should be fine.
