1. *1 When connected to a USB power supply, Level 5 automatically operates at a higher cooling level "Level 5+". After the mobile battery is consumed, the cooling level will return to Level 5 and will last for approx. 4 hours using the built-in battery.
2. *2 When connected to a USB power supply, Level 4 automatically operates at a higher cooling level "Level 4+". After the mobile battery is consumed, the cooling level will return to Level 4 and will last for approx. 2 more hours using the built-in battery.

No. The battery cannot be replaced.

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.

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.

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 supports low current mode to avoid the problem of stopping charging halfway.

Use one with an output of 1A or more, featuring overcurrent protection, and include a USB cable.

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.

Charge the battery for at least 30 minutes and then try again. To charge the battery fully, it takes the time below.

For RNP-P1 
About 200 minutes

No, that is not possible.

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.
