MINNEAPOLIS — A Twin Cities man is facing a fourth surgery after he was burned by an off-brand cell phone charger.

Tim Tyrell said he was just trying to save a few dollars when he searched eBay for an iPhone charger. Tyrell said he found three chargers for under $10. But, when he received the merchandise and plugged a charger into an electrical outlet, it tripped the circuit breaker and caused what he says was a “mini explosion.”

Tyrell suffered a small burn that later became infected. It’s taken three surgeries so far to tackle the infection.

Tyrell just wants to warn others about buying knock-off phone accessories. The cut-rate price might not be worth it.
