How can you charge the Anker Astro E1 power bank? What is the charging time? How to check the capacity of the portable charger?
CAUTION: Electrical Device. Read the safety instructions!
Connect the Anker Astro E1 portable charger to a power source (such as a computer or power outlet) using the supplied Micro USB cable.
The four LEDs indicate the charging progress. Once the power bank is fully charged, all four LEDs will shut off. A full charging cycle takes about 5 hours, depending on the chosen power source (e.g. 2A power charger, max. 2.4A).
Step 3 (optional)
The small button on the side of the device can be pressed to check the current battery status.
- 1 LED flashes: Battery has 25% capacity.
- 2 LEDs flash: Battery has 50% capacity.
- 3 LEDs flash: Battery has 75% capacity.
- 4 LEDs flash: Battery has 100% (full) capacity.
When the Anker Astro E1 charges a device and the device switches off because its battery is fully charged, the power bank will switch off as well. But it can be switched on again by pressing the button.
The USB port is powered off while charging. It is therefore not possible to charge another device at the same time, thus no pass through charging.
The Anker Astro E1 should be charged every 4 months at the latest in order to avoid damages to the battery.
