Frequently Asked Questions

Q: How do I know when the ESMARTER COB keychain work light is fully charged?

A: When you plug in the USB-C charging cable, the indicator light turns red to show it's charging. Once the 800mAh battery is fully charged (typically within 2–3 hours), the indicator light switches to green. Disconnect the cable promptly after charging is complete.

Q: Can I use this keychain flashlight in the rain or wet conditions?

A: Yes! The WJ808 carries an IPX5 waterproof rating, meaning it can withstand direct water jets and heavy rain without issue. However, it is not designed for submersion, so avoid dunking it in water or using it underwater.

Q: How many lighting modes does this COB keychain light have, and how do I switch between them?

A: The light features 5 modes: single-side light, double-side light, high-beam, near-far combined, and strobe. A short press of the power button cycles through the modes in order. To jump directly to the brightest mode, hold the power button down for a long press.

Q: What charging adapter should I use with this keychain work light?

A: Always use a standard 5V/1A USB adapter with the included Type-C cable. Avoid fast-chargers or high-current adapters, as these can damage the built-in lithium polymer battery. The package includes a USB-C cable; you just need a standard USB wall adapter or power bank.
