Frequently Asked Questions

Q: How long does the ZHIYU S11 mini keychain flashlight take to fully charge?

A: The S11 features a built-in 260mAh polymer lithium battery that fully charges in approximately 35 minutes via its USB-C port. The LED indicator turns red during charging and switches to green once fully charged, so you always know the status at a glance.

Q: Is this mini flashlight truly waterproof? Can I use it outdoors in rain?

A: Yes! The ZHIYU S11 carries an IP66 waterproof rating, meaning it is fully protected against powerful water jets from any direction. It is also drop-tested to 1.5 metres, making it a reliable companion for camping, hiking, fishing, and any outdoor activity where the elements are unpredictable.

Q: What does the UV/violet side light do?

A: The side-mounted UV (violet) light is useful for everyday tasks such as verifying banknotes, detecting fluorescent agents on surfaces, and identifying certain stains invisible to the naked eye. It switches on as part of the multi-mode side light cycle (white → white flash → UV → red → red flash → red-blue alternate flash).

Q: How does the magnetic tail cap work?

A: The powerful magnet embedded in the tail cap of the S11 allows you to attach the flashlight securely to any ferromagnetic metal surface — such as a car roof, a steel shelf, or a tool cabinet. Combined with the red or red-blue flashing side light mode, it can serve as a hands-free emergency warning light wherever you need it most.
