Excuse the error in my maths. More like 130W, not 300W 😂

The ring where you insert the tip can be unscrewed. Then there is a 1.5mm hex grub screw under the display cover. Unscrew it and you can slide out the PCB.
The microcontroller has all the markings engraved away sadly. It is in a SOP-20 package.
I took a few pictures of the PCB I could share.

CH224K USB PD chip, NCE30P25S P-channel MOSFET and an SE8533 3.3V regulator. The PCB is marked V1.16-L245

There is a newer version L245P with a DC barrel jack supporting 24V input so it is basically the same as the JBC power supply voltage.

If the bench is outputting a max of 6A at 20V aren't you applying a max of 120W instead of the 300W you referenced in the video?

"all kinds of clicking glad to hear that real life EE in a hurry is alive and well...😀....Happy New Year Steve, all the best for 2023.

[allthegearnoidea]

Same here been sick with it for 4 weeks just starting to feel better.

20 volts and 6 amperes does make for 120 watts and not 300...? Did I miss something?

[davadoff]

Metcal always does better with the coin test is because RF delivers power into the surface of the tip where the temperature is falling.

JBC has a resistive heater buried relatively deep inside the core of the tip. Heat has to conduct to the surface from within.

I think the thermocouple in JBC is located closer to the heater than the surface of the tip. If it was closer to the surface, it would probably perform better.

If the 245 cartridges are 2.5 ohm (?) and you supply 20V, peak current could reach 8A. Maximum power needed is then 160W. Due to the pulsing, the power supply has to be large and robust enough to be able to handle the on and off switching. I wonder if you only get the full potential from this with a custom power supply. Negates the portability thing if you can't use a standard PD charger (max 100W).

Nice video Steve, hope your health stays fine. I've had exactly the same Bug. Thanks for sharing.

2nd try without link to Banggood:
Than you for your great videos 👍
I would be extremely grateful for the test of the new open source soldering iron PTS200 T13 100W 🙂

[IanScottJohnston]

Is there a hidden screw under the display cover perhaps to let you gain access?

[M.E]

I got a similar c210 version, works fine with original tips, also I got a sunshine one that comes with a stand which is c245 and they do c210 version, it uses 15v usb c adaptor but couldn’t get it work with 15v powerbank, it comes on but turns off after a few seconds

After my ts100 died a few weeks ago im looking for a new, more powerfull but still cost effiective soldering iron.
I have a 100W USB C PD charger and also a 20V 12A PSU if i ever need more than usbc power.
Would you recommend this iron? Or should i instead go for a read soldering station? Im not planning to use it as a portable iron.

[rangwankasantikul]

How is the "80w" generic 908s (old-style tips) irons compares to the T12 irons? Been looking for a cheap, but meaningful upgrade over my current 908s iron.

[medienmond]

Your link in the description to the T420D is not valid anymore...

[M.E]

I know maybe you can’t do this but do you think you will be testing the new genuine JBC cordless soldering iron/station?
It does cost basically £500 so I doubt it’s something you need or would even use or spend that much money on

[wotfinowski]

After few uses soldering iron screen black, no response :(

[svtouring]

Wow Steve, I love your channel and this is the most interesting subject yet. An old 35W Metcal is my go-to, but the allure of cheap JBC clone tips is just too tempting. With the release of the Pinecil short (and lower resistance) tips, I expected the matter of "best" portable to be settled for a while, but this no-name has me wondering.

When you say you rigged-up a USB cable to your power supply, would you mind sharing the specifics? I would assume it's not much more complicated than applying DC voltage to the 2 thickest wires in the cable, but I don't have any USB-C devices I'm willing to risk losing to an experiment.

If you have time, how about a head-to-head between this device and the Pinecil v2 with short tips? I mean the total experience, not just thermal performance.

How to change language to english. Also is it possible to update firmware? In differet videos different versions from 1.1 yours to 1.3
