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%).
