SCANDAL ALERT!! ... THE AMOD/WOTOFO MYSTERY CHIP COVER UP CONTINUES ...
So ... I was just over the in the APV section reading through the ZNA thread, and I happened across the post of someone who opened up their Amod ZNA and took pictures of the chip.
Well, and what do I see etched on a little steel casing on the chip? ... 4R7
http://www.e-cigarette-forum.com/forum/variable-voltage-apv-discussion/554717-zen-zna-clones-coming-52.html Why is this significant?
As some of you may recall, when I first contact the manufacturer Hao sheng regarding the Vapor Flask V1 clone they are making, I asked about the chip and was told that it was a US made 4R7 chip. After calling the rep on her BS about it being US made, she would later admit that the 4R7 chip is in fact Chinese made.
You may remember that I would later comment on stumbling across this 4R7 chip again on the Electhinker ZNA clone that VC ran a deal about two weeks ago. Then late last week Wallbuys lists a no name ZNA50 that is 18650 only and also has this 4R7 chip in it.... this darn chip is famous
Therefore, I think it is fair to say that in spite of Amod's statements regarding how they came to acquire a Yihi chip for their clone, which Yihi denies both manufacturing and supplying (according to Yihi they do not make a chip called sxa300) that this latest revelation confirms that there is no Yihi chip in the Wotofo ZNA.
What this also further helps us to determine is the quality of the 4R7 chip, which appears to be used in a lot of China made regulated devices. The only issue that I have had with this chip is that it does not perform that well with sub ohm on a 18500 battery. But other than that it is clearly not a bad chip, its just not a Yihi chip ... and now I understand why Amod stuck a branding sticker on the picture of the chip they gave me, which was also featured in my review ... they needed to cover up that 4R7 engraving
