The T6 mini start-up starter unit can provide sufficient power to start up a 5-liter gasoline engine or a 3.5-liter diesel engine. It has 2 USB ports 5v and a LED torch 3 functions. This is a hands-on demonstration of the unit starting my 1.8-liter gasoline engine that has a starting current of 214A measured with the 12v battery at full capacity.
