Nearly half a million portable power banks are being recalled because they can overheat and pose the risk of a fire while phones are plugged in, officials said.

NEW YORK (AP) — About 429,000 portable power banks are under recall because they can overheat and potentially catch fire while charging phones, posing a burn hazard to consumers.

The issue is with the lithium-ion battery on the model, with the number E33A printed on the back. The consumer product safety commission says it can overheat and start a fire or cause burns.
