2nd Gen Astro E3 External Battery
PowerIQ: Max speed charging & universal compatibility.
Ever wonder why your smartphone charges faster from some charging ports and slower from others? Often, it’s not just the power that your charger can offer. Instead, it comes down to compatibility. Some ports simply don’t speak the right language to open up your device to full speed charging. Try plugging an iPhone into an Android adapter, or vice versa, and your charge time could double.
Our solution? Anker’s PowerIQ technology intelligently identifies your device and speaks with the language it needs for full speed charging. Charge with confidence that with PowerIQ, together with Anker’s industry leading power output, you'll always enjoy true universal compatibility and full speed charging — no matter your device.

Astro E3 Power Indicator Instructions
Press the power button once to trigger the LED indicator and display the remaining power.
1.Each of the LEDs represent 25% of the battery’s capacity.
2.The LED indicator will turn off when the device is fully charged.
3.The LED indicator will stay on when charging a device, displaying the battery’s remaining power and will turn off when the device is fully charged and not drawing a current.
4.The LED indicator will not activate when the battery is empty.
Notes
1.To protect the long-term capacity of your device’s battery, please unplug the power wire promptly after the device is fully charged.
2.During the charging process, approximately 20% of external battery’s total capacity will be consumed, including power lost from circuit heat and voltage conversion within the external battery (approximately 16%) and the charging cable and your device (approximately 4%). This efficiency rate is 15% higher
6
than the industry average of 35%.
3.Since the combined output of both ports is limited to 3A, concurrent use of the two ports may slow the charging process.
4.Please fully charge your external battery at least once every four months to avoid shortening its lifespan.
5.Keep the product away from extreme heat or cold, as well as any flammable items or damp places. Also avoid dropping, hitting or throwing the product.
FAQ
1. Which port should I use to charge my device?
Thanks to PowerIQ technology, each charging port can charge any device at full speed – no need to decide between them.
2. Can I use the Astro E3 to charge 2 devices at the same time?
Yes. But when using 2 output ports simultaneously, the total output current will not exceed 3A.
3. What if the Astro E3 fails to charge?
Check that the adapter connection is secure, or replace the adapter if the current one is not functioning normally.
7
4. What if the Astro E3 fails to charge other devices?
Ensure that the power cable is securely in place, or check that the Astro E3 voltage is compatible with the electronic device's required charge voltage. Please refer to your device's instruction manual, product labeling, or adapter to find this information.
5. Why can’t I charge my Bluetooth device with the Astro E3?
The Anker Astro E3 external battery will not charge devices with input currents lower than 50mA, including some Bluetooth and GPS devices. Instead, Anker Astro E3 will power down automatically.
6. Can the Astro E3 pass-through charge (charge and discharge at the same time)?
Yes, this battery can simultaneously charge and discharge. However, constant pass-through charging may affect the battery’s lifespan.
