A part of the review has been auto-translated.
The TP4056 boards are all ok and working, I placed a fake board I got a few years back beside one of them to show the difference in the traces and chips. the fake board has very thin traces, and questionable chips, the back of the board has not got heat dissipation holes under the main chip line the real boards that just arrived from banggood. 👍 (the board I. the picture with the pen)
Very good-looking material, well-made welding points, just to test because I received today 12/27/2021. Only downside was the lack of address on the packaging. I don't even know how the GLS could deliver the package to me.
Good product.

Received in order. Thank you.
Thank you again
Solar panel with 9 cells Works. The IC family has an input overvoltage protection at 5.60V, (Voc...) charging is switched off. 5V (10 cells) solar module with 5.6V Z-diode and sunrise works until charging then the Z-diode burns without protective resistance ;-) The Ic stabilizes at 4.5V (MPP 9 cells) and automatically adjusts the chargingstom.
ok.thanks
It's nice
Foi a segunda vez que comprei. Excelente. Entrega rápida pela a Banggood.
