I have been a member for a few months and have never gotten a PM how can I prove I can get them?
If you got the PM I just sent you, you’re set to get them.
If you didn’t, start digging in your profile settings.
They’re all “USB”.
It sounds like you have a standard USB A charger (rectangular opening, sharp corners) and a USB A to USB C cable. That should work fine.
my bad, a typo, (fixed it) 
Got it! Thanks
Image below shows what type of chargers that will work, ( any USB charger that has the standard larger common USB-A socket) and the type of charger that will not work (the ones that need to use a type-C to type-C cord on both ends)
Hey Den, did you know of a source to get some high capacity 18650s in Canada for a decent price? Everywhere seems to be around or over 50CAD shipped for a set of 4, is that about what to expect if not ordering a large bundle?
I recall you mentioned something about 18650canada a while back and those are the figures I’m getting from that site for 4 Sanyo NCR18650GAs.
Could you point to the location(s) where a resistor may be effectively installed?
Does this completely activate the full USB-C function? Or is more change required. Like a new chip.
@ dbsar
@ lexel
Are you sure about the pull up resistors?
Can someone point Lexel to this page? Tabelle 3.02
https://kompendium.infotip.de/usb_power_delivery.html#Kap3.5.1
It is in German.
I would not vote for full USB-C support
USB-C stuff is quite complex to implement. You need to know all this stuff:
- USB 2.0 Spezifikation (April 2007)
- USB 3.1 Gen 2 Spezifikation (Juli 2013)/USB 3.2 Spezifikation (September 2017)
- USB Power Delivery Specifikation, Revision 2.0 (März 2016) / Revision 3.0 (Januar 2017)
- USB Billboard Device Class Specification, Revision 1.2
- USB Battery Charging Specification, Revision 1.2
Do you really need USB Power Delivery for the LT1? The 3A or 1.5A on 5V should be enough.
But I am not an USB expert

If I understand this discussion correctly one would have to cut traces on the PWB in order to install the 5.1k ohm resistors. A new chip is not required. Depending on how the board layout is, IMO its not really possible for someone to make the necessary change on a purchased lantern without seriously risking damaging the lantern.
No.
True, but that still requires resistors. By default (without resistors) there is no 5V coming out of a USB-C charger.
Nice BLF family photo with the GT peeking between the Q8 and LT1! :+1:
I think this is the first time I’ve seen the LT1 next to a Q8. It gives a good idea of size, even after seeing all of Den’s videos of the LT1.
Are the 600lm from the manual are for all 7 or for the 5 soldered?
For genuine cells here in Canada, i buy all my Li-Ion cells from https://18650canada.com even though it seems that we pay more, ( due to our weak CAD) its still not bad as other prices are in USD elsewhere.
Last first - No. There is no way to support the full USB-C spec in the LT1. It will not fast charge, will not function as a power bank, or support any of the ‘fancy’ USB-C features.
Where the resistor goes… I hate to say it like this, but sometimes blunt is the best kind of answer. If you have to ask, it’s probably not for you. This is not a simple “Connect pad L to trace G” process.
Now, in case you are qualified, lines CC1 and/or CC2 from the UCB-C connector have to be separated from ground and a 5.1k resistor inserted. This is delicate surgery, and currently untested on the LT1 driver. While some here are undoubtedly qualified to do this, most of us aren’t.
Some folks have managed to do this with the Raspberry Pi 4, so it’s not impossible. It is, however, risky enough that I’m not going to give any instructions that may lead to someone trashing their LT1.
For the majority of us, using a USB-C to USB-A (female) adapter between your USB-C charger and USB-A to USB-C cable (supplied with the lantern) is the best answer.
To make the LT1 full USB-C support will probably add cost, and not worth for just the some of compatibility with a odd few type-c chargers, (honestly we could have saved cost if we had stayed with the plan to use the standard USB Micro plug interface, which that interface is still going to be around for a long time yet. We only went with the USB-C plug because a few members kept pushing for it, which ended up making things more expensive & complicated, (and this petty issue with the complaints of some type-c port chargers not working could have been completely avoided, AND saved cost & time by going with the still far more popular micro plug as originally intended. :person_facepalming:
Folding lamp shade for the LT1
Finally found a white one, colored is no problem on Ali.
only the hole in the bottom is missing

:+1: That is the exact one i used for the folding lamp top shade in the Youtube video i did.
If only mailing these to CA wasn’t such a royal mess. :person_facepalming:
What percentage of packages do you think Canadian customs would inspect and confiscate?
Nah - ignore that. I’m not up for risking my money, and I don’t want to risk your money either. (or get put on yet another list)
Did you cut the black ring off, or did you get the one that’s out of stock and might have been plain white?
