Good quality, screws included, works well. It delivers 100W for output and 60W for charging, which is good because it hardly heats up while charging.

Everything works; I soldered it by hand in a hurry, and there's no place where I can work quietly. I have kids running around, but I managed to do everything and installed Samsung 50 batteries; everything works without any problems.
Arrived quickly, in 14 days. The quality is excellent. You need to be patient for a good assembly.
Works great. I recommend it.
The package arrived quickly. Everything is fine. I assembled the construction set, and everything works as described in the order. When charging at 60W, it heats up and at some point goes into protection mode, then it recovers on its own. Protocols are in the photo. I'm happy with the power supply! 5 stars to the seller!!!
Prompt shipment and fast delivery. thanks to the seller. visually power bank plate looks very decent, no complaints. this is not first time i have purchased this diy case and i have never had any problems. i have not tested this particular product and i am giving it five stars in advance based on my personal experience and reviews from previous buyers. if there are any problems with connection, i will update my review later.
