USB Power Bar

Got too many chargers and when I need one, all are occupied by my kids and wife. So I decided to install a multicharger in every single corner of the house. It took me a bunch of testprints and redesigning but in the end it works out quite well. All you need is a small transformer, a DC-DC stepdown converter, and USB ports. I bought these plugs: https://de.aliexpress.com/item/Free-shipping-50pcs-lot-USB-2-0-jack-USB-connector-female-4P-180degree-DIP-H-13/1926212826.html?spm=a2g0s.9042311.0.0.wdnK2o May you have a leftover power converter from an old laptop. I use this stepdown converter https://de.aliexpress.com/item/CNIKESIN-Diy-kit-DC-DC-adjustable-step-down-Regulated-power-supply-module-Belt-voltmeter-ammeter-Dual/32811977282.html?spm=a2g0x.search0104.3.22.79a8e1d8NP1Occ&ws_ab_test=searchweb0_0,searchweb201602_5_10320_10321_10065_10344_10068_10342_10547_10325_10343_10546_10340_10548_10341_10194_10084_10083_10618_10304_10307_5722315_10180_10313_10059_10184_10534_100031_10103_441_10624_442_10623_10622_10186_10621_10620_10142,searchweb201603_36,ppcSwitch_7&algo_expid=dba5d3d4-d54c-463a-ba1e-96268b2b69c0-3&algo_pvid=dba5d3d4-d54c-463a-ba1e-96268b2b69c0&priceBeautifyAB=0 because I can set it perfectly to 5V and it shows me the consumption properly as well.
