6. Thickness: 0-0.35mm;

7. Start-up Voltage: With built-in memory function, the start-up voltage is the same as the last voltage value at which the machine was turned off.

8. Working voltage range: 5-12V;

Instructions:

The device is a tattoo pen with built-in lithium battery, which can be used directly without the need for a foot pedal or guiding line. It is composed of two parts: 1. The upper half is the lithium battery power supply, and 2. The lower half is the tattoo pen. The middle part can be rotated to replace the upper half of the lithium battery. The specific function operation is as follows:

1. Power on: Press and hold the "O" button for 5 seconds to turn on the device, then press and hold for another 5 seconds to turn it off.

2. Pause: Press the 'O' key briefly to pause the work, and press it again briefly to resume the working state.

3. Adjust the voltage: Use the "+" or "-" key to adjust the voltage level. Press once to adjust by 0.5V. Low voltage: 5V, high voltage: 12V.

Battery display: The LCD screen shows 4 bars for a fully charged battery, and when there is only 1 bar left, it's time to charge.

5. Daily Charging: The external charging port allows you to charge using an Android USB cable.

6. Lithium Battery Warranty: Warranty for one year, you can purchase the upper half of the lithium battery separately for replacement.

Power Parameters:

1. Input: The device is charged through a USB charging port, and then the lithium battery is charged. It has three built-in batteries, each with a capacity of 600mA and a voltage of 3.7V.

2. Output: The output current is fixed at 2A. The lithium battery releases its stored charge through the start button, powering the built-in motor to start the tattoo pen. Voltage settings: (5-12V) Switch between voltage levels by pressing the "+" or "-" key. 5V is low voltage, and 12V is high voltage. Each adjustment step is 0.5V.

3. Battery capacity: Charge through the included USB cable, and it will take 1.5-2 hours to fully charge under normal conditions. The battery is fully charged when the indicator shows 4 bars. With 8V operation, the device can last more than 7 hours. The voltage is stable. When the battery level is down to the last bar, it's necessary to charge to ensure normal operation in the future.
