DIY UPS – part 3 – with 12V and 19V (for Asus router)

Hi guys! I hope you are doing well.
I made a few modifications to this UPS and I will share them with you in this video. The UPS will switch to battery power much faster now and I used a new PCB for the relay circuit. I received it from JLCPCB. It will simplify the build a lot, so if you want to build your UPS with this PCB, just upload the gerber file to JLCPCB website and place the order.

Feel free to visit https://jlcpcb.com to order professional PCBs at low prices for your projects. $2 – 2Layers 5pcs; 4&6Layers starting at $5.
