Car phone charger works in a 12v car port but explodes from a 12v DC adapter? Answered
I've got a lighting project that is powered by a 12v power supply and is driven by a 5v arduino. I want to minimize the amount of wiring I run to the project and power the arduino from the 12v power supply. One of the instructables recommended to use a simple car phone charger. 12-24v to 5v. Well I did and the thing exploded. I checked the polarity (bought a few of them) and it's correct, there's also an onboard LED for indicating power on. Thing lights up, works for a second and smoke starts coming from the IC.
What is so different between the car 12v and DC adapter 12v?
the onbaord IC is ADB85063
