12 V lead-acid charger and starter
This unit charges and jump-starts 12 V lead-acid batteries in cars, motorcycles and light commercial vehicles. Three selectable rates let you match the current to the battery type and condition. An integrated ammeter shows the real-time charging current at a glance.
Switchable rates with visual feedback
A rotary switch selects 2 A trickle, 10 A fast charge or 50 A engine-start mode for the task at hand. Separate LEDs confirm when mains power is present and when the battery reaches full charge. The built-in meter removes guesswork during extended charging sessions.
Replaces separate trickle charger and jump pack
Owners who currently keep a low-current maintainer and a portable booster can consolidate both functions in one bench-top device. The step up is worthwhile when you want a single tool that handles routine maintenance and emergency starts without switching equipment.
