Budget wall adapters are practically disposable — until one fails in a way that's actually dangerous. We put ten sub-$5 chargers and generic wall supplies through six months of hard use, then cracked them open to see what was left. The results ranged from surprisingly solid to genuinely alarming.
Counterfeit and wildly mislabeled USB-C Power Delivery chargers are everywhere on US marketplaces, and they're not just annoying — they can fry sensitive electronics and ruin builds you've spent weeks on. We break down exactly how these fakes work, how to test what you actually bought, and which budget brands are worth trusting.
