I purchased the ZC916. But the seller sent another product. As a result of checking in Taobao, the product I received is ZC918. This product (ZC918) affects between 27W Port and 100W Port. When I plug and unplug the 27W Port of this product, all ports are always reset and power is restarted. The original ZC916 seems sold out. I asked the seller to give me the original ZC916 but did not respond. Dispute was rejected. Do not buy this product. Seller send ZC918 instead of ZC916. I can not use this product because of this defect of ZC918. I will throw this product into the trash.
