According to the Consumer Product Safety Commission, hydrogen gas can leak from the speaker’s battery while it’s charging. The leak can cause the speaker to burst, which poses an explosion hazard.

The commission says ION Audio has received five reports of speakers exploding. In four incidents, the explosions caused property damage. No injuries have been reported.
