are power strips a restricted item that will get pulled from your bags if found? I know some have posted about bringing them to increase outlets.
A power strip with a 15 amp circuit breaker, a UL listing, and no protector parts should be safe. Would create a least risk. Internal protector parts have a history of (in rare cases) causing a fire. Details posted here.
Best is to take one that would create a least risk. However confiscation can be arbitrary.
