*BLF LT1 Lantern Project) (updated Nov,17,2020)

It was all described and discussed above. Many/most USB-C chargers do not provide power until asked – and the LT1 does not ask for power. That’s all.

This is the used USB-C socket

Pin 3 and 9 are the CC2 and CC1 lines

When the LT1 was first released, they were sold through Ebay and people could submit an offer for the group buy price including their username to get the group buy price. They (Sofirn) subsequently terminated this distribution method because people were able to “game” the system. I’m sure Sofirn will make sure that everyone on the list receives a lantern. Sofirn has been very good to the BLF community and visa versa and I’m sure this case will proceed in a similar manner.

cool bro

Sofirn has stated that everyone on the list will get all their LTs at the group price. They have been very responsive in fixing any issues that have arisen (correct pads are being bridged, changing them to be in parallel rather than series, working to resolve the USB-C charging issue, etc). I haven’t seen anything that has risen to even annoyance level in my thinking but obviously some may feel otherwise.

These changes will be rolled into future production so if anyone feels that they need to have them then it’s better to wait a bit longer :slight_smile:

A buddy of mine got his LT1 and I was lucky enough to play with it. It is hands down the most feature complete, best overall lantern I’ve seen. Great work DBSAR, ToyKeeper, Sofrin, and everyone else involved! I can’t wait to get mine.

Sorry, what? The guy stated maximum power draw, not maximum charge current, I have no idea what this has to do with single cells or multiple low impedance ones?

The lantern is capable of illuminating from USB, if the lantern is on and charging at full rate then ultimate demand on USB could be much higher than the quoted 7.5w, it’s not an issue as the USB will limit output and may not charge cells whilst lit but this is a limitation to be aware of.

The iPhone is USB C going forward, the iPad and the MacBook are already using it for some time.

I’ve only been waiting for this for… when did they sign on with the USB-C Consortium and ditch the dock connector?

The 11 pro ships now with USB C charger. The 30 pin dock ended in 2012, it has been USB A chargers until the new pro.

The capabilities and capacities of the charging port are appropriate for the intended charge rates.

The fact that the lantern can operate at all on power supplied through the USB charging port is a happy accident.

That’s fine but not relevant, the potential draw is higher. It’s simply something to be aware of. All electrical circuits are designed with maximum demand as a consideration.

Just got my LT1 and using an XTAR EU4 charging unit it displayed .09A at 5.28V It slowly climbed to 3.02A at 5.28V when I disconnected it and the LT1 blinks out 4.1V Is it supposed to charge at that high a rate?? Especially when the batteries are topping off?

That’s in excess of 15w, was the lantern on and charging or only charging with the light off?

What cable/ports were you using?

Might sound silly, but was there anything else plugged into the EU4?

It was off. The switch leds were red.

please disregard :person_facepalming: mAH is different from A :blush:
The sky is definitely not falling.

All these people moaning about full USB-C specification compliance should have chimed in a year or two ago, :confounded:

Most, if not all people, were not aware of the problem if one wanted to use one of the newest chargers with the smart cords. . Even the makers of the Raspberry Pi messed up on their new version 4.

I was just about to comment on that it’s display likely switched over to milliamps as the batteries reached full charge. :partying_face:
