actually it does but only if i have a USB->USB-C adapter plug
i got a real USB-C charger, from an amazon seller wanting me to review it
the wuben will not do anything when plugged to that
but it does - like i said, if i have a normal USB charger, with a USB->USB-C adapter
i even had the company send me another one, and, same thing
the charger only has USB C out
but they sent a cable with iOS connector, it will charge my iphone, so the charger is not dead
i assume it is impossible for 2 usb c cables to be bad
what would make the wuben do nothing when plugged to that usb c cable?
(if it;s already charged, it is still supposed to glow green in the switch, so that isn;t it)
Some older USB-C will only work if you have a cable that is USB-A to USB-C. They won’t work with USB-C to USB-C cables. I don’t know technically why but it’s usually mentioned in a lights specs.
USBC can be a mess. Many manufacturers stick a USB C connector in their device and call it good without implementing the rest of the standard. It’s likely your charger adheres to the standard and your light does not. The charger is looking for the right resistance to tell it to turn on, and it’s not getting it from the light. The older USBA charger sends power regardless, so it doesn’t care what it’s hooked up to.
Edit, I just saw your second response. It could be the charger just doesn’t work out of the box.
USB was originally only meant to carry data, and small amounts of power. It wasn’t envisioned as the primary conduit by which electronic devices would be charged, and couldn’t meet such demands. But it became the de facto method, and the market addressed the standard’s power deficiency via a variety of proprietary “fast charge” standards that piggybacked onto USB (Apple 2.4, QC, VOOC, etc.), each with different power capabilities and none compatible with each other. A veritable free-for-all that would quickly be confusing to any user who stepped outside their brand’s bubble and tried to make sense of it all, never mind possessing any concept of Ohm’s Law.
The new era of USB-C was supposed to address many of the past deficiencies.
The new standard would be the Holy Grail of connectors, and serve every demand a user would ask for, and best of all, reduce the cable clutter and round peg/square hole dilemmas of the past. In theory, anyway…
But, it only served to stir the pot, if not arguably make things worse in some ways, by shifting the complexity from the connector ends to the cable itself.
By trying to cram every standard into one type of cable (of which there are actually eight types of C-to-C cables alone), it served to make it more difficult to discern the intended function of a particular cable.
Also keep in mind that USB-C refers to the connector standard only, not the high power standard (Power Delivery), nor the data standards (Thunderbolt, USB 3.x/2.0). And since Qualcomm wasn’t going to allow their license money train to roll to a stop, QC4 was drafted to function over C (QC3 over C is verboten), and co-exist with PD.
What was meant to be simple didn’t turn out that way in practice.
Many conflate USB-C with PD as being mutually inclusive, but that is not necessarily the case. It is possible for USB-C to be implmeneted without PD. (Or without USB 3.x, or Thunderbolt. Those cheap USB-C cables all over Amazon aren’t capable of Gb speeds, only USB 2.0.)
Yet, to do that properly requires some effort on the part of the designers to specify the role that their device plays.
Few, if any, flashlight makers initially made that effort, and simply slapped the C-connector into their devices and called it a day, leaving it partially functional and limited to A-to-C charging. A light from two years ago is almost certain to fall into this category, and many current models still do as well.
Hence, it should not be a surprise to find that a C-to-C connection between a power adapter and flashlight does absolutely nothing.
I tried charging my Wuben T70 in 2 ways “USB-C / USB-C” style.
First was with the Xtar R30 flashlight that acts as powerbank through the USB-C port. I used an On-The-Go cable and also a small adpater.
Second, I tried the 18650 cell that came with Wuben D1; it has a USB-C port (in and out), and I used the adapter cable and mini USB-C adapter.
In both cases, the T70 switch starts blinking red and blue, meaning that the flahslight is not charging.
I tried a regular USB-C cable with a charger, and it worked well, so I guess the USB-C / USB-C doesn’t work at all in this flashlight!
Port-to-port isn't the issue. You have a charger that is intended for smart devices and apparently somehow omits basic functions the port. The charger talks and listens...so do phones and tables and such. It's two-way communication and when they shake hands they can decide upon what current to charge with. Your flashlight charging circuit is just dumb electronics. So in this case the charger isn't going to deliver anything until the device tells it what to deliver, which your flashlight cannot do, so the charger sits lonely and silent.
Try another charger with a type c port, or a laptop/pc type c port and your light should do just fine. The flashlight's dumb electronics will just limit the current to whatever they designed it as and the charger/computer will just feed pixies without saying a word or trying to listen to anything.
