7.4 Car jump start assist for emergencies:

1. Note that the cubic capacity of a vehicle (e.g. car, including other means of transportation like motorboats)

may not exceed 4 L.

2. Make sure that the battery‘s capacity is greater than 60 % (four battery segments).

3. Make sure that the clips of the jump start cable are not damaged.

Car jump start assist

1. Before you connect the PSU to your car‘s battery, it is necessary to switch off all other loads drawing bat-

tery power in the car

2. Attach the red clip now to the positive pole and the black clip to the negative pole of the car battery.

3. Plug the other end of the jump start cable into the provided socket of the PSU.

4. Turn the key to start your car as usual.

5. After starting, you can remove the cable from the unit and then remove the black clip (ground) and the

red clip (positive) from the car battery. The sequence must always be observed, since noncompliance could

otherwise result in a short circuit.

NOTE

Make sure that prior to starting the red and black clips are securely attached

to the car‘s battery poles and that there is sufcient space between the clips such that they can

not fall or touch each other due to the vibrations of the vehicle‘s engine.

Failure to do so may result in a short circuit and damage the vehicle‘s electronics or even the PSU.

The red and black clips must NOT come in direct contact with one another.

That could otherwise result in serious accidents.

While the car‘s engine is starting, make sure that you stay away to prevent any possible injury

that may be caused by the running engine.

are not permitted to use the car jump start assist function.

Instruction manual

LE5B – Portable Power Supply

8. Estimated running time

Device current from the PSU

• Smartphone (2-4 Wh) 100+ charge cycles

• Tablet (25 - 42 Wh) 10+ charge cycles

• Laptop (50 Wh) 8+ hrs.

• Desktop computer (100 W) 4 hrs.

• Mini refrigerator (30-60 W) 6-12 hrs.

• 32“ LCD TV (98-156 W) 2-4 hrs.

• Vacuum cleaner (200-300 W) 1-2 hrs.

• Mixer/processor (200-300 W) 1-2 hrs.

It is a good idea to check the wattage of your device if you want to determine how long the PSU is able to

power it.

Check the capacity for the individual output connections. For instance, the AC connection is monitored by a

power inverter, which enables a continuous output of 300 W. That means if the device requires more than

300W of power over an extended period, the PSU‘s power inverter will switch off. As soon as you know that

your device is compatible, you should determine how long you are able to operate your device with the aid of

the PSU. Here is a quick guide:

Watt hour (Wh) is the unit of battery capacity and measures the amount of power that can be stored after a

full charge. It tells you whether your equipment is compatible with the respective charger. For instance, a 200

Wh battery should be able to power a 100 W lamp for 2 hours (200/100 = 2). If your equipment has a capacity

of 390 Wh, you need to check the limitations of the output connections.

NOTE

The above data are to be used only as reference points.

The approx. values were determined with an ambient temperature of 25 °C and fully charged battery.

These values may vary, depending on the manufacturer of the electric device, unit, etc.

Devices may not operate, even if the output of the power supply unit is below 300W,

for certain types of electrical devices.

In case of overload, the unit is switched off automatically and output is interrupted.

In case of Plasma TVs, LCD TVs with screens greater than 41“, desktop computers, and other devices

with high power consumption, as well as household devices with uctuating power consumption

or with power factor correction may not operate normally or at all, even if the their specied

operating power is below 300W.
