Well packaged, received in good condition and excellent delivery time (14 calendar days from order). Includes acrylic shell.
perfect has arrived very fast. It is exactly as described. It works very well and has a very good price.
received, enjoyed very well finished, the case exceeded my expectations
Comes with a very nice clear acrylic self assemble case. Acrylic is covered with protective stickers which are hard to remove making the assembly quite long but its a nice little unit as you can see.
ok
Dear Sirs,, I bought three of these as I wanted to set up a charger for lithium batteries. The plexiglass covers for it looked good. On your picture there are back and front and side peaces but when I opened the package there was only back and front. The holes did not line up with the connectors which I found strange but then I found that the fixing holes did not line up with the fixing holes in the corners of the printed circuit board. Even though I have read the instructions I have not yet been able to configure this to give me a constant voltage and current. Please see pictures. Due to the size I will probably send two e-mails.
This is by far the best little buck converter for someone that is using a 20v laptop power supply as a li-po charger. The voltage can be adjusted to accommodate a 1s to 5s battery. Best function is that the current can be controlled. Will be buying a few more to use around the house.
Good to my project.
