What owners report

Wurkkos HD20/5 sources reviewed

A big 21700 headlamp with two emitters — a high-CRI neutral flood and a spot — USB-C PD charging, and a power bank function that some reviewers noted was the first they'd seen do C-to-C PD properly. Runtime and high-mode performance are both strong, and the flood beam is well suited to close work without burning through the cell.

It is, by common consent, the largest headlamp most reviewers own. That bulk buys the runtime but makes it a camping and work headlamp rather than something you'd run in. Two specific faults come up repeatedly: switching between the two emitters fails roughly half the time, and the head strap is lower quality than the light deserves. The XP-L HD spot emitter is also an odd choice — at 141 m it doesn't throw as well as the format allows.

Consistently praised

High-CRI neutral flood emitter alongside a dedicated spot
USB-C PD charging, and it works as a power bank for a phone
Excellent runtime and sustained performance on high from the 21700
Rugged enough to double as a standalone right-angle flashlight
Flood beam is well judged for close-range work

Common complaints

The largest headlamp most reviewers have handled — bulky on the head
Switching between emitters fails around half the time
The head strap is noticeably lower quality than the light
The XP-L HD spot emitter under-throws for the format at 141 m
UI niggles, including losing moonlight when you switch emitters

Questions people ask

Is it too big for a headlamp?: For running or fast hiking, yes. For camp, work and static tasks the weight is a fair trade for the runtime, and it comes off the band as a right-angle flashlight.
What's the emitter-switching problem?: Reviewers found the control to change between flood and spot doesn't register roughly half the time, so you press again. It's an annoyance rather than a fault that stops the light working.
Can it charge a phone?: Yes — it supports USB-C PD in both directions, which was unusual for a headlamp when it launched and is genuinely useful on a multi-day trip.
HD20 or HD15?: The HD15 is the 18650 version: smaller, lighter and cheaper, with less runtime. Most people are better served by the HD15 unless they specifically want the 21700's endurance.
