Can I replace the battery?
No. The battery cannot be replaced.
What USB AC adapter is recommended for charging?
Use a commercially available USB AC adaptor with overcurrent protection for safe operation, and also one capable of supplying an output current of 1A (1,000 mA) or more to have fast charging work.
Can I charge the battery with a mobile battery or a PC?
Yes. However in the following conditions, charging may not work.
- When a mobile battery cannot distinguish between low current charging and charging completion, it might stop charging partway through.
- Charging with a PC will depend on your PC model, software, or settings.
What kind of mobile battery do you suggest me to use?
Use a commercially available USB AC adaptor with overcurrent protection for safe operation, and also one capable of supplying an output current of 1A (1,000 mA) or more to have fast charging work.
Also, a mobile battery that support low current mode to avoid the problem of stop charging halfway.
What kind of AC adapter or mobile battery should I use to use fast charging?
Use one with an output of 1A or more with overcurrent protection and included USB cable.
When I use the device with USB power, the app shows an error message saying "The device battery has run out of charge" even though the mobile battery is still charged. Is this a malfunction?
The device battery can also be drained depending on the selected temperature setting level and airflow. Leave the device to charge for a while and then try again.
When the charging cable is disconnected, the device will not operate. Is this a malfunction?
Charge the battery for at least 30 minutes and then try again. To charge the battery fully, it takes the time below.
For RNP-3 (For Hong Kong only)
About 100 minutes
For RNPK-4 (For Hong Kong only), and RNPK-5
About 170 minutes
For RNP-P1
About 200 minutes
Can I turn the power off?
No, that is not possible.
What kind of USB cable should I use when I use the device with USB power?
The USB Type-C cable provided with the device will be ideal, and when using a commercially available USB cable, we recommend it to be an L-shape USB Type-C for wearing comfort.
What kind of USB cable should I use when I use the device with USB power?
The USB Type-C cable provided with the device will be ideal, and when using a commercially available USB cable, we recommend it to be an L-shape USB Type-C for wearing comfort.
Can I purchase the charging cable that comes with the REON POCKET separately?
