The vast majority of aftermarket electronics won't survive a load-dump transient. This includes every AC inverter, every USB charger, every laptop PSU, whatever you find at the store.
Most 12v-targeted electronics are good to about 30v transients. The DC-DC converters would likely be no more or less susceptible than the DC-AC inverter used here. Just quieter, smaller, and more efficient.
