Sigelei-20W SX220 Chi-N-A 20

Today I received my sigelei-20W. SX200 chip. It came in a nice box without an instruction manual. The first battery that my Provari was running on was Orbtronic Protected 3100 mAh that is slightly larger but it fits in sigelei-20W. It didn’t work. I guess Sigelei-20W didn’t like Protected batteries. I replaced it with Sony US18650VTC5 2600 mAh, Sigelei-20W liked it. Who wouldn’t? I put Taifun GT on it which I thought was 0.7 Ohm:

But Sigulei-20W disagreed with me, my Ohmmeter and EVIC and Fluke. Sigelei-20W said it was 0.5 Ohm and would not fire it. Even though Manufacturer claimed that it fires anything from 0.5 to 3.0 Ohm, it is untrue: It will not fire 0.5 but it fires 0.6 and up.

Then I put 1.2 Ohm Ithaka and tested my Sigelei-20W at full power of 20 Watts. See for yourself how it is trying to put out 20W but it only is able to provide 19.28 Watts. It ran 4 Amps of Current through my Ithaka and fried it.

I think I’m going to keep it because it is the only Regulated MOD on the market today (that I’m aware of) other than DNA20 and 30, which is capable of handling 0.6 Ohm builds at almost 20 Watts. And unlike the DNA 20 and 30 it only costs $83.77 at Fast Tech and it arrived in 10 days.
I hope this helps the future Sigelei-20W buyers.
Best regards,
Mike.

Phil Busardo ran the full gamut of tests on the 20W v the DNA20 with his fancy equipment and concluded that the 20W is every bit as accurate as the DNA20 chip, and the the biggest gap in between what he was supposed to be getting versus what the 20W was providing was, under virtually every circumstance, no more than .2v.
