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: Adjust the voltage level by pressing the '+' or '-' key. Each press adjusts 0.5V, with the minimum voltage at 5V and the maximum at 12V.
4. Battery Display: The LCD screen shows 4 bars for a full charge, and when the battery is down to the last bar, it needs to be charged.
5. Daily Charging: The external charging port allows you to charge using an Android USB cable.
6. Lithium battery warranty: one-year warranty, 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 650mA, and the voltage of the battery is 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 settings by pressing the "+" or "-" key. 5V is the lowest voltage, and 12V is the highest. 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 is down to the last bar, it's necessary to charge to ensure normal operation in the future.
