The Wurkkos WK03 is a compact 90 degree EDC flashlight that stands out for its low price, standard 18650 battery support, and magnetic tailcap for hands free work on metal surfaces. The beam is fixed rather than adjustable, and the magnetic mount locks the light perpendicular to whatever it sticks to. Color options are described as neutral white at 5K or cool white at 6K. Caveats include reports of dim output, early failures, and slow transit from the Global Warehouse. A small, inexpensive light if the fixed beam and battery size fit the job.
Common Questions (5)
No. The WK03 has a fixed 90° beam, and the light itself is not adjustable. The magnetic end cap only lets you mount it to metal surfaces and aim it by changing the surface angle.
Not well. It is likely too heavy to hang on a hat, and its short body makes clip positioning less secure than on longer lights. A lighter 18350 light like the Sofirn SC13 is a better hat-clip option.
Yes. It takes regular 18650 cells, so replacements are easy to source. At this price, buying an extra WK03 can even be cheaper than buying a couple of standalone 18650 batteries after shipping.
It can be dimmer than expected, and there are reports of units stopping working after a few months or after the warranty period. The included 18650 battery may still be usable in other flashlights even if the WK03 itself fails.
It can take around 20 days in transit. One CA buyer saw tracking show the package in the US while it still had not arrived after 20 days from the Asia-based Global Warehouse.

Alternately you can go cheap and salvage cells from an defunct laptop or li-ion power tool battery... (buyer beware, no safeties here...) Check youtube for how toos. Can get good quality brand cells like Samsung and Panasonic out of old laptop batteries, though with flattops they don't work in all devices.
