Review on ✨ Tiktecklab A4 Size Ultra-Thin Portable Tracer White LED Artcraft Tracing Pad Light Box with Adjustable Brightness for 5D DIY Diamond Painting, Artists, Drawing, Sketching, Animation - Black by Marvin Nadeau

Hope this helps someone before they decide they have a problem like me! I was very happy about the light box and immediately unpacked it and connected it. Although it comes with a USB cable, it didn't include an adapter or square spade lug to plug it into an outlet. I didn't want to connect it to my laptop as I know it doesn't have enough power to avoid flickering. I was at the kitchen table with my phone plugged into the wall adapter in the wall with the same cable. Exit. There are two holes for usb cables to charge two different things and it just charged my phone. So I plugged in the light box cable and hit the power button. The light went from low to high when I held it longer. When it reached about 1/2 potential brightness it started to flicker. When I turn the brightness down to the minimum it stays constant but I need more light! After thinking about it, I realized that this is how a SPLIT of power occurs. *** When I unplugged the phone and all the power went into the box, there was no blinking! *** Good. Most people will probably find out right away, but just in case. That's all! Except for this problem, everything is exactly as described and works great! Insanely light, sleek and sleek. I can trace on the box by looking at the box! See photo! The first photo is printed cardboard covered with striped yellow cardboard. The second image is white card stock under white card stock at maximum brightness.* If this was helpful, I would really appreciate it if you click the USEFUL button below! Thanks very much!
