How many of their compact/EDC-style lights have a boost driver? (Hint: the driver is 22mm)
What other brands do, and how much do they cost?
Because it’s the 1000th+ time I’ve seen the terms used interchangeably here: Regulation and stabilization are not the same thing. Every flashlight that isn’t pure direct drive is regulated. Not taking a shot at you, but people always seem to make an association between good efficiency and full stabilization which is absolutely not always true.
I personally don’t really like the design of the overall body, I prefer one with knurling like the SP40. That didn’t stop me from buying one though, I wanted to wait until the SP40 would get updated with type c-c charging functionality but the additional throw/flood/powerbank functionality is something I really liked about this one! Also I assume I might be able to swap the body with another flashlight down the road so yeah 
I also do not like the wavy tubes used by Wurkkos, but I do like the quality/price ratio of their lights :money_mouth_face:
I’ll buy it when both LEDs are at 3000k or less and hi cri.
I don’t think they’ve ever heard of quality control…
I received my hd20 last weekend. Unfortunately, the 2 rubber rings of the headband are torn so that it is no longer possible to use the lamp as a headlamp.
There is also some dirt or scratches on both sides of the reflector, but I don’t think it will affect the beam much.I wasn’t able to make any pictures of it, it’s only visible when light is on
I think Lux hit on something that’s true for me when it comes to the HD20. The SHTF utility light has a lot of appeal to me. If I HAD to use the HD20 as a headlamp, it’s a capable headlamp. It’s fine as a handheld. And it can be somewhere in the middle (worn in pocket). It pretty much does all the tricks (takes multiple kinds of battery, charges via USB, battery bank when you need one). There’s not really anything else that does that anywhere in this price range. Would fully regulated/stabilized output make it better? Sure, you’re going to win some customers with that. You might lose some too if that makes it much more expensive or takes you longer to get it out to the market. Something consumers don’t see is the downside risk of not getting a product to market earlier.
I like the wavy tube body of the Wurkkos lights. Provides a nice option when most lights on the market has knurling.
Whut?
All its missing is a red led
So you want [let me count…] 3 LEDs?
Has anyone tested charging HD20 with type C-C cables yet?
Has anyone tested reverse-charging an external device from HD20 using a type C-C cable or type C-Lightning cable yet?
On TLF some members reported that some cables refused to work properly, especially when attached to a smart power source with PD protocols (9V, 12V, 20V).
Normally, HD20 should override these protocols as two resistors should always enforce the 5V 2A standard protocol even when using type C-C cables.
I am trying to collate as much information as possible to give Wurkkos a summary for technical improvement (provided that there is an actual problem with HD20 or some cables).
Yeah the design has grown on me. I didn’t like it before but once I got it in person I started to like it.
I don’t have an hd20 yet, but the fc11 does C-C. I have charged mine that way.
Yes me, works perfectly (don’t know the charge current on top of my head).
Type C - C cable works fine. You can pull more than the advertised 1.6A but the voltage sags down. I don’t know what the cuttoff-current is, I could pull more than 2-2.5A (but at about 4V instead of 5)
The light works fine with my Baseus 65W charger (supports a lot of different protocols) and the supplied C-C cable, haven’t tested it with other cables. It just asks for 5V.
They only thing I miss is smooth ramping and the Anduril battery-voltage measurements, otherwise it’s a very capable light! Also the threads could feel more durable when screwing on the magnetic tailcap with a 21700 battery. I like the “feel” more when screwing in one of those batteries in my C8G.
I plan to review it once I can take some beamshots, I wrote some bullet-points down already…
Charging works fine here, got 1.4A so far
Thank you guys. The most important question is, will HD20 charge with a type C-C cable properly on PowerDelivery chargers? I am not talking about the type A-C cable (big plug - small plug) which seems to work on every type A charger without problems. Can you please also test the powerbank feature using a type C-C cable. Some smartphones already use a USB-C port or Apple's new iPad Pro. Any feedback will be helpful. I hope I find some time to testing my HD20 soon, too.
Yes, I charge everything with the Baseus 65W PD charger and a Type C - C cable (phone, laptop, camera, HD20)
Works like a charm, charges my Xiaomi Mi A1 with a Type C - Type C cable just fine. My Type C meter measures 4.6V at the end of the cable (so a bit on the low side) at 1.45A. The phone displays “Charging rapidly”
Received my Wurkkos HD20 from Amazon US yesterday using the 20% discount from the BLF "HD20 Sales Thread". Thank you Wurkkos and Lux-Perpetua for another interesting and unique light.
Using USB-C to USB-C cables known to be of high quality, the Wurkkos HD20 would only charge from just one of my five PowerDelivery (PD) chargers using the charger's USB-C port.
Only the "Anker Model A2321" (120 VAC input) charger with PD would charge the Wurkkos HD20 using the USB-C port on the charger. My inline USB meter indicated that the charger's USB-C port supplied the included battery (which was discharged to 3.47 VDC as delivered) with 4.96 VDC at a starting current of 2.10 A which tapered off until charging terminated where the battery measured 4.14 VDC when out of the light using a multimeter after a short rest.
I also have an "Anker Model A2625" (120 VAC input) PD charger and an "Anker Model A2229" (12/24 VDC input) PD charger and neither of those would charge the Wurkkos HD20 using the charger's USB-C port.
I have two different types of USB-C PD (120 VAC input) chargers from Apple for my MacBook PRO (charger Model A1718) and for my MacBook Air (charger Model A1882) and neither of those would charge the Wurkkos HD20 using the charger's USB-C port.
Curious if you always used the inline USB meter to determine that the other PD chargers were not charging on USB-C?
I’m not sure how inline USB current meters handle PD protocols. If you take the USB current meter out of the equation, do you get different results?
I tested both "with and without" the inline USB meter to be sure the meter was not affecting the results.
Just received 2x HD20’s and it’s just straight out unattractive and the weight on my forehead is too much. It’s pushing the skin down and feels heavy on my eyes.
I’ll certainly not be selling this model, very disappointing
The design looks cheap, not liking the shiny ano, no knurling as it’s all smooth but that has been on all of the Wurkkos models.
Get rid of the powerbank feature, give it magnetic charging and some proper cooling fins like on the Skilhunt H04 RC, it would also shed some weight. Sofirn/Wurkkos could be so much more then a budget brand if they put more effort into the design.
Thumbs up for trying something different but I can’t sell this at these prices. Cost the same as a dealer to get the C8F. I bought it to try just in case.
Maybe Wurkkos should make their own version of the Skilhunt H04F RC that has a diffuser lens that’s fitted on a hinge. Skilhunt failed on their model with the hinge of the diffuser reflecting light into your eyes.
Everyone has been wanting the SP40 with a 45° tir lens so maybe Wurkkos should of built something like that.
As a flashlight it’s okay, but 4 leds and a tir lens would still be way better and also helps with the weight.
