Automatic Charger for Vehicle Batteries

This 12V automatic battery charger provides selectable charging rates of 2A, 5A, 10A and 20A to suit different battery conditions. It also delivers a 50A engine start function for emergency cranking assistance. The unit is designed for cars, motorcycles, boats, farm machinery and RVs, and comes with multiple connectors for various terminal types.

Mains-Powered Operation and Amperage Limits

The charger requires a 120-230VAC 50/60Hz mains supply, so it must be used near a wall outlet or suitable generator. Its charging output is capped at 20A, while the 50A rating applies only to the engine start mode. Users needing higher continuous charge rates or fully portable operation without mains power will need a different class of device.

Black and Yellow Housing with Two-Year Coverage

The black and yellow enclosure houses components specified to meet or exceed original equipment manufacturer specifications. A two-year warranty backs the build quality. Multiple connectors are included to simplify day-to-day hookup across the range of supported vehicles and equipment.

Questions about this item

Which charging rate should I pick for a car battery versus a motorcycle battery?

Use the 2 A or 5 A settings for smaller motorcycle batteries and the 10 A or 20 A settings for larger car batteries; the 50 A engine-start mode is reserved for cranking an engine.

What does the 50 A engine-start rating mean when I am trying to start a vehicle?

It delivers up to 50 A of cranking current at 12 V to help turn over a petrol or diesel engine when the battery is too weak to start on its own.

What input voltage range does the charger accept and what output voltage does it provide?

The unit accepts 120–230 V AC at 50/60 Hz and supplies a regulated 12 V DC output for charging and engine starting.
