Big Clive disassembles and analyzes an IKEA Koppla USB power supply to evaluate its safety, isolation, and transformer design.

I've always recommended using prominent brand USB chargers for safety. So I thought I'd take an IKEA one to bits and assess it for safety with regards to isolation and transformer construction. If you enjoy the videos on this channel you can help support it with a dollar for coffee, cookies and things to take apart at patreon.com/bigclive

What people say. Recommended as a detailed teardown demonstrating high-quality safety design in brand-name USB chargers compared to cheap alternatives.

TL;DR: spend the $19 to buy a real, big brand USB charger because they have more to lose than grey market no brand. Tragic. Probably cheap USB without mains isolation or maybe enough water dripped down length of cable and socket to create a circuit, because USB is supposed to be 5V DC. Watch these USB charger teardown horror-shows to further understand why it's rational to pay for proper, authentic CE+UL, high-low isolation and quality components (ie insulated tape in transformers): link link to this video link link link link
