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 four months to
avoid shortening its lifespan.
4. Do not try to charge and discharge the Astro E5 at the same time, as this
may reduce the battery’s lifespan.
5. The battery is 82% 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 your device (approximately 15-20%).

Check that the adapter connection is secure, or replace the adapter if the
current one is not functioning normally.
3. What if the Astro E5 fails to charge other devices?
Ensure that the power cable is securely in place, or check that the Astro E5
voltage is compatible with the electronic device's required charge voltage.
