【Voltage-Drained Battery Savior】 TowerTop battery charger, up to 84% more efficiency, detects and charges batteries as low as 1 volt, ideal for dead or idle 12v lead-acid batteries including STD, GEL, AGM, and DEEP CYCLE. Fully-automatic features, manual selections, and prior-setting memory function make charging automotive battery more convenient and high-efficient.

【Superior Engine Start and Winter Mode】 Engine start aid feature helps in activating your car battery with insufficient power to emergently start your vehicle in 100 seconds.

Auto-stop when fully charged, auto-awake and pulse compensate after voltage drops allow a long-time connection, with charging fuller and battery more durable.

【HIGH QUALITY&FAST INFLATION】The air compressor for car accessories uses the original high-speed pure copper design turbocharger core, Built-in copper wire setting-high temperature resistance, does not blow the fuse,faster speed, Portable air compressor can work continuously for up to 30 minutes, and at least 6 tires can be inflated at a time. The air pump can inflate the 205/55R16 car tire from 30 to 35 PSI within 1 min.

【AUTO FUNCTION&SILENT】The air compressor tire inflator can preset the pressure required by the tires, with automatic detection of tire pressure and automatic shutdown, no need to worry about over-inflation or low tire pressure.Due to the movement of the tire air compressor and the internal upgrade of the foot pad,the sound and jitter when charging is reduced by half.
