Intro: Car USB Multi Charger Under 2$
I don't like cCar multi chargers as attached.
Bad quality, short lifetime and ect.
I connect all 12V devices with hand made charger
Step 1: Materials
Step 2: Tools
Step 3: Positive Pole Wire
Step 4: Negative Pole Wire
Step 5: Connection
I connected my one using inside fuse box.
Use any BUSY fuse where 12V comes every time you start your engine
Outside fuse box in this video is used as example
Step 6: Check
All works great
I connected 4 devices, hid wires
