Fedtro model CH-AHD battery charger
date: label: date made
content: ca 1966
notes: label: Description (Brief)
content: Fedtro model CH-AHD battery charger on package. This unit purports to charge batteries of all types, but ordinary carbon batteries are not rechargeable and attempting to recharge them creates a significant safety hazard. The UL citation refers only to the cord and connector plug, a typical two-lead 18 gauge cord, not the entire unit. The patent referred to (258299) may refer to a Japanese patent. US 258299 is an unrelated 1882 patent for a pen point; and US D258299 is a 1978 design patent for a toy chain saw.
