How to charge
The charging method for this device is as follows.
Plug the included magnetic suction into the Type-C charging interface on the AsReader, and then connect to the Type-C charging cable to charge. We recommend using a 5V/3A charging adapter.

If a mobile device is connected, both the device battery and the mobile device battery are charged.
The power indicator LED is red and remains on while the device is being charged. When the device is 100% charged, the power indicator LED turns green. Depending on the state of connection to the mobile device, the LED indicator may blink or keep on.

※ when AsReader is off, once the type-c charging cable is connected, it will automatically start up and enter the charging state.
※ The power indicator does not show the charging status of the mobile device. Check the display on the mobile device for its charging status.
※ When an Android device is connected, communication with the Android device cannot be performed if the battery of this device is charged, so please disconnect the USB-C charging cable before use.
※ It needs to take 3.5 hours to fully charge the device when the battery runs out.
※ When using the device for the first time or if it has been left unused for a long period of time, please fully charge the battery of this device before use.

Warnings
Do not charge the device with a power adapter other than 5V, since this may cause a malfunction and is not covered by the warranty.

Supplementary Information
Mobile devices (iOS and Android devices) can be charged separately by AsLock Gender.

AsLock Gender ASA-018C is recommended.
If AsLock Gender ASA-017C is used for charging, as the charging current it can provide is limited, the charging time may be longer than that of ASA-018C.
When charging with AsLock Gender ASA-018C, it is best to use the micro USB charging cable that supports quick charging in combination with it.
