4. Operating Instructions
4.1 Powering On/Off
Locate the power switch on the control panel. Flip the switch to the 'ON' position to activate the Coolbox's electronic features. Flip to 'OFF' when not in use to conserve battery life.
4.2 Using USB Charging Ports
The Coolbox features two USB ports (DC 5V 2A and DC 5V 1A) on the front panel. Connect your electronic devices (phones, tablets, etc.) to these ports for charging. These ports can be used when the Coolbox is unplugged, drawing power from its internal battery.
4.3 Bluetooth Speaker Operation
- Ensure the Coolbox is powered on.
- Activate Bluetooth on your mobile device.
- Search for available Bluetooth devices and select "Coolbox" to pair.
- Once paired, audio from your device will play through the marine-grade speakers.
- Alternatively, use the 3.5mm AUX input for wired audio connection.
4.4 Detachable LED Light
The integrated LED light can be detached from its housing for use as a multi-angle wand. It provides up to 4 hours of illumination on a full charge, ideal for low-light conditions or emergency situations. To re-charge, place it back into its designated slot within the Coolbox.
4.5 120V Pass-Through Power
When the Coolbox is plugged into a wall outlet, the rear 120V pass-through power outlets become active. These outlets, along with the 3-way splitter, allow you to power small tools or other devices directly from the wall outlet, even if the Coolbox's internal battery is not fully charged.

5.2 Storage
Store the Coolbox in a cool, dry place when not in use. Ensure the lid latches are securely fastened to maintain the air/water-tight seal. If storing for extended periods, it is recommended to fully charge the internal battery every 3-6 months to prolong its lifespan.
