Review: converter - work good '
Review: They work great! - These voltage reducers are being used to allow me to use a 12v adapter with my coleman inflatable mattresses. The idea being to skip the use of 4 D batteries (weight). The modification allows me to use my Jackery to power and inflate the mattresses when camping while avoiding the issues with D batteries, both the weight and chance of them giving up the ghost at the wrong time, ie. while camping.... Excellent value and looking forward to many camping trips.
