Wurkkos TS22 high parasitic drain, and overcharging

[zoulas]

How many times do we have to go through this. Electronic switches come at a huge cost.

If you want to get all the benefits of the lithium battery use a mechanical switch.

We tend to think that all new technology is good technology. This unfortunately is not the case.

Electronic switches and Andruil and all that nonsense will leave you with a light you cant use when you need it. This may cost you your life.

Remember a flashlight is a tool. Same like a hammer, same like a vice grip.

You want it to be dependable and reliable and any technology that compromises that should be disregarded.

There is parasitic drain and there is excessive drain. Some lights will last years before thy deplete the battery.

YES!!!

Back to on a stick you go. No wait, that’s bad in the rain.

I really dislike this bs too. I also wish there were options for each model to not have on board charging.

So it is. I guess it is so with all the big diesel powered tucks and equipment that maintain our internet connections.

That’s is not the point, the point is there is a bug in the driver. On the auto lockout it has reasonable parasitic drain 130-110µA, on the other two modes, the parasitic drain is excessive 3600-2000µA.

When I measured 4mA parasitic drain on my jetbeam rrt01, they sent me new driver, no question asked (I did provide the photos)
When I measured 4mA parasitic drain on my mateminco mt35 mini-s, they refunded me the whole cost.

But here it’s just a bug, the driver is OK, it’s possible for it to behave normally with resonance parasitic drain, but you are forced to use the auto lockout mode. Can’t really open dispute with them about it. But maybe I should do it, I message terry about this months ago, for them to fix it, but it’s still not fixed, even in new versions…

for me it is the point. More complexity is more to go wrong; this problem would not exist with a mechanical switch. It’s also been discussed here how the power bank / charging module can be problematic too, and that’s without mentioning the obvious water ingress weakness. I’m happy that there are many people who love these increasingly complex lights, I just wish there were a few lights that prioritised simplicity and reliability / ruggedness more for the rest of us. I wish the sofirn c8g came with more led options - that would be ideal because of its great switch combo, no onboard charging.
