Never used, I think there was a Manuel but cannot find it


Typical specifications include:

* Around 550 A peak current, suitable for most petrol cars and smaller diesel engines.
* Built-in lithium battery that can also charge phones and other USB devices.
* LED flashlight with normal, SOS, and strobe modes.
* Reverse-polarity and short-circuit protection built into the smart jumper clamps.

What it can start

A healthy DJ550 should generally be capable of:

* Petrol engines up to roughly 3.0–5.0 litres.
* Diesel engines up to roughly 2.0–3.0 litres, depending on temperature and battery condition.

Performance drops significantly in very cold weather or if the vehicle battery is completely dead.
