Frequently Asked Questions - Astro E7 Anker

Which port should I use to charge my device?

Thanks to PowerIQ™ technology, each charging port automatically adapts to your device. Use any USB port, they all deliver up to 3A.

Can I charge three devices at the same time?

Yes, the Astro E7 can charge up to three devices simultaneously. Note that the total output current must not exceed 4A.

What to do if the Astro E7 does not charge?

Can I use the external battery while it is charging?

It is not recommended to charge a device while the external battery is being charged, as this may reduce its lifespan.

What to do if the LED light does not turn on?

If the LED light does not turn on even though the battery is supposed to be charged, the battery is probably completely discharged. Recharge it first.

What is the battery lifespan?

The battery can withstand several hundred charge and discharge cycles. To maximize its lifespan, fully recharge it every 4 months even if not in use.

Compatibility maximized: Meeting your device's unique charging needs.

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.

Our solution? PowerIQ™ technology communicates with any connected device by speaking its unique charging language. Each port intelligently identifies your device and adapts to its specific recharge rate. So thanks to PowerIQ™, together with Anker's industry-leading output, you can enjoy maximum compatibility that doesn't limit your charging speed.

Usage 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. 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.
3. Please fully charge your external battery at least once every 4 months to avoid shortening its lifespan.
4. Do not try to charge and discharge the Astro E7 at the same time, as this may reduce the battery's lifespan.
5. Since the combined output of all ports is limited to 4 amps, concurrent use of the 3 ports may slow the charging process.
6. The battery is 92% efficient, accounting for power lost through circuit heat and voltage conversion, which is up to 10% above the industry average. Energy is also lost within the charging cable and your device (approximately 15 - 20% ).
