The Sonic booster range offers professional and reliable solutions for all users. In terms of power, our range starts where other competitors end theirs. Our least powerful batteries deliver more power than most average batteries of competing products. Don't be misled by booster and battery ratings! When it comes to jump starting vehicles, what really maters is the power in Cranking Amps (CA), not in Peak Amps (PA). In addition to powerful AGM batteries, our boosters are all equipped with high-quality components; double insulated cables, fully insulated clamps with curved and bronze jaws and resistant Anderson connectors. The Sonic boosters are professional tools designed for professional and intensive use.
