Olight O’Pen 3 Rechargeable 4-in-1 Penlight
The Olight O’Pen 3 is a multifunctional 4-in-1 pen made of anodized aluminum, designed as a versatile writing instrument and compact tool for everyday carry (EDC), inspections, and presentations. With a total length of 15.6 cm, a diameter of 12.7 mm, and a weight of 40 grams, this tool combines the size of a standard ballpoint pen with four separate lighting and pointing functions.
The pen integrates a Class 1 green laser pointer (Class 1R, $\le$ 0.39 mW) for safe and precise pointing, a white clip light for general work lighting, a subtle white light near the pen tip for writing in the dark, and a red LED to protect night vision. The white clip light delivers a maximum light output of 120 lumens with a range of up to 14 meters. The barrel has a slightly tapered profile and features a milled meteorite pattern for a stable grip during extended writing sessions.
Power is supplied by a built-in 3.7V lithium-ion battery (130 mAh), which can be fully charged in about one hour via a hidden USB-C port. Performance is distributed across the available modes as follows:
- Clip Light White Mode 1: 120–60 lumens / 14 + 25 minutes
- Clip Light White Mode 2: 60 lumens / 60 minutes
- Clip Light White Mode 3: 20 lumens / 2 hours and 20 minutes
- Clip Light White Mode 4: 2 lumens / 26 hours
- Red Light Mode 5: 10 lumens / 1 hour and 20 minutes (including SOS signal mode)
- Red Light Mode 6: 5 lumens / 2 hours and 10 minutes
- Pen-tip light Mode 7: 0.4 lumens / 26 hours of runtime
- Green laser Mode 8: Class 1R ($\le$ 0.39 mW) / 7.5 hours of operating time
Benefits for the Target Audience
- Four tools in one housing: Combines a smooth-writing pen, a flashlight, a presentation laser, and a discreet reading/night light into a single portable device.
- Writing in the dark: The focused 0.4-lumen pen tip light illuminates only the paper directly around the tip, allowing notes to be taken without dazzling those around you.
- Eye-safe Class 1 green laser: Provides a clearly visible aiming point for presentations, education, and construction inspections with a safe power class.
- Integrated red night vision light: Helps the eyes adjust to the dark and, with its SOS mode, serves as an immediately usable emergency beacon.
- Hidden USB-C fast charger: The internal charging port is securely concealed within the housing’s screw mechanism and fully charges the battery in approximately 60 minutes.
- Ergonomic writing comfort: The meteorite pattern on the grip section prevents fingers from slipping during intensive writing.

- Charging: Twist open the pen body to reveal the hidden USB-C charging port. Connect the cable to a suitable USB power source; the built-in indicator shows when the 130 mAh battery is ready for use.
