This product is basically for those who have experience with battery principles and soldering. A wrong voltage can easily damage the product. Overall, I am satisfied, but why is the maximum charging voltage only 18W?

Based on 5 reviews
A very good set. Supports 20W fast charging and assembles tightly like the factory one. I liked the quality.
I received a product with a different base than what I ordered, and the return/refund process is poor. Please be careful.
I am satisfied with the product.
Unfortunately, the piece needs to be one size larger.
I assembled it with the pieces I had, and it was perfect.
There was a bend in the corner of the aluminum case. Other than that, there were no issues.
