OSRAM BATTERYjumpstart 2000 OJS040 – powerful 12V lithium jump starter
OSRAM BATTERYjumpstart 2000 OJS040 is a portable lithium-ion jump starter designed for 12V vehicles. It delivers 400A cranking current and up to 2,000A peak current. OSRAM rates the unit for petrol engines up to 8.0L and diesel engines up to 4.0L.
Key benefits
- 2,000A peak current – suitable for a wide range of 12V vehicles, including larger engines within OSRAM's stated limits.
- 0V Boost function – allows the jump-start procedure to be used with a deeply discharged vehicle battery.
- 16,000 mAh internal battery – also enables the unit to function as a portable power bank.
- USB-C charging – convenient recharging using a compatible USB power source.
- Large colour display – provides clear operating feedback.
Engine compatibility
According to OSRAM, BATTERYjumpstart 2000 is intended for 12V vehicles with petrol engines up to 8.0L and diesel engines up to 4.0L. This makes it a useful emergency accessory for passenger cars, SUVs, pickups, off-road vehicles and campers that fall within the manufacturer's stated operating range.
0V Boost mode
OJS040 includes a Boost function specified by OSRAM for starting batteries from 0V. This feature is intended for situations where the vehicle battery voltage has dropped too low for the normal starting procedure. Always operate the Boost function in accordance with the manufacturer's instructions.
Power-bank capability
The integrated lithium-ion battery has a stated capacity of 16,000 mAh and the unit can also operate as a power bank. The jump starter itself uses USB-C charging. Current OSRAM documentation contains conflicting 60W and 65W Power Delivery figures, so an unverified PD wattage is deliberately not stated in this specification.
Compact dimensions
The unit measures 230 × 48 × 100 mm. OSRAM also states that a carry bag and cables are supplied, helping to keep the jump starter organised in the vehicle.
