The KSGER T12 (one on left w black handle) is a bit faster but the tip is much bigger.  The Jabe (one on right w green handle) is rated at 130W vs the KSGER's 70W altough the power supply in the KSGER is 24V x 5A which is 120W.

My view is that the Jabe is not that much better than the KSGER, certainly not to warrant the $180 price tag; the Jabe is heavier and more expensive probably because it uses a power transformer vs the KSGER's SMPS.

I'd have to get bigger tips for the Jabe to make a better comparison - I might buy one honking great big one.

Interesting. I would have thought the Jabe would at least equal the KSGER. Even though the tip is smaller is has a good thermal mass at the base. It can supply more power and I would think the Jabe has a faster control loop. Maybe try a genuine JBC tip?

Now if they could cut the prices in half. The station is over $200. And the tips are $11-15 and up. Would be nice if the cost was the same as the knock-off FX-951 and T-12 tips.

I've had one of these for about a week now. It works well but the LCD quality is not as good as the original JBC. It's a bit wishy-washy with inconsistent blacks across the display but still quite usable. The other thing is that I had to add an offset of about 20 degrees C to get the tip temperature to match up with the display temperature. It would be nice if JABE could add the tip calibration procedure the KSGER has so you can store different profiles for the many different tips. Also as one of the youtube reviewers said it does not work to well with the C210 Nano iron and tips. But other than that it is as solid and quality made as the original JBC ;)

cheers

If they're gonna do a good knock-off they may as well rip off the control circuitry too.   ;D

Shock:
Might want to make sure on the T12 clone the SMPS has proper primary/secondary isolation, it's been mentioned the ones with the air gap may have a heatsink that has inadequate clearance.

For your own safety never expect those cheap smps to isolate live voltage properly when switched off. They often are switching neutral, so pull the plug to be sure. Might pay to check both the top and bottom of the PCB for any obvious design or assembly mistakes, while you are there clean the flux off any hand soldering.

Would be interesting to see how much it overshoots as well, I've seen in video jumping around as high as 30C at idle, so this probably explains why you feel the performance is better than the Jabe. But it was probably unrealistic to expect JBC performance from the Jabe anyway.
