Not your standard jump starter! This unit goes beyond the standard budget jump starters available on the market starting with the powerful 17Ah lead-acid battery, making it last longer and the power go further. This is very important as some engines, such as boats need the additional starting current. Rugged insulated battery clamps are fitted to extra long cables making it easier to access hard to reach batteries. Waterproof grommets are fitted to the cable entry into the unit's main housing. A cigarette lighter socket is fitted to the side of the unit so you can still use it as mobile power pack (eg when camping). A handy work light is fitted to the front panel for night time work and it also has a battery charge meter. The battery is charged by mains plugpack (included). Features: -Extra long 850mm heavy duty cables -Strong 17Ah battery as standard -Test button with voltmeter -Rugged, go-anywhere design -Dimensions: 330(W) x 380(H) x 100(D)mm
