Light aircraft systems are 14v or 28v. This product is rated at 12v and its big brother at 24v. Will the 12-14v and 24-26v discrepancies lead to aircraft systems damage?
No, the 12 volt version can be used on 14 volt systems without damaging the system. Same goes for 24 volt version on 28 volt aircraft systems.
Does this 12 volt portable power supply charge the battery, act as a power supply, and crank assist?
The three port adapter will power the panel, the alligator clips will charge the battery but will not do crank assist.
