Buyer questions

Q: How long does it take to charge a USB-C battery?
A: A standard 18650 battery charge via USB-C takes about 3-4 hours, depending on the power of the charger. To get full power quickly, use a QC3.0 or PD fast charging adapter. On a full charge, your headlamp will work continuously for about 6-8 hours at maximum brightness.

Q: Is the USB-C headlamp waterproof?
A: Yes, Sofirn HS21 has IP65 waterproof and dustproof rating, which means it is safe to use in rain, wet environments and dusty places. However, it is not recommended to dive it underwater because IP65 is not deep water resistance.

Q: Is the battery included in the package?
A: The 18650 battery is usually not sold separately. Please check the product description in the TopSmart store - if the battery is not included, you can purchase it separately. We recommend high-quality 18650 lithium-ion batteries with a capacity of 2500 mAh or more.
