Frequently Asked Questions

Can this unit provide a boost to a completely discharged battery?
Yes. With a 140A peak starting output (110A EN), it is designed to provide boost power to help start vehicles with flat batteries in professional settings.

What vehicles is this battery charger and engine starter suitable for?
It is suitable for passenger cars and light commercial vehicles including Transit-sized vans. The switchable 12V/24V output and 15–240Ah range make it useful for mixed fleets.

Why is the 15–240Ah battery range important?
Fleet operators and garage owners often handle multiple battery types. The wide 15–240Ah range helps ensure compatibility across cars, vans, and many light commercial vehicle batteries.

Does this unit help protect vehicle electronics during charging and starting?
Yes. It includes built-in polarity protection and a panel-mounted fuse to reduce the risk of damage to expensive vehicle ECUs during use.

Why use an analogue ammeter instead of a digital display?
An analogue ammeter provides instant, easy-to-read feedback so technicians can monitor current flow at a glance, which is especially useful in busy or low-light workshop environments.

Is this unit portable around a workshop?
Yes. With a 7kg net weight and heavy-duty carry handle, it is designed for grab-and-go movement between service bays and vehicles.

Is it mains-powered?
Yes. It operates from a 230V supply, making it ideal for fixed workshop use where consistent power and repeatable performance are required.
