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 fluctuating power consumption
or with power factor correction may not operate normally or at all, even if the their specified
operating power is below 300W.

12.1 Frequently asked questions
What type of battery is installed in my PSU?
Your PSU uses a 11.1 V, 35 Ah lithium ion battery. An individual Li-Ion battery is much smaller than normal sealed lead acid batteries (SLA). The cycle life is also longer than that of normal SLA or AGM batteries. In addition,
lithium ion batteries will last longer if they are not fully discharged.
How can I see if my PSU is charged?
To check the charge state of your PSU, consult the battery indicator on the LC display. If it is illuminated, you
should see the battery‘s status indicated with five segments, showing the current charge state. You can switch
on the battery display by pressing the ON/OFF button on the MASTER power supply for two seconds. It is
acceptable to use the PSU even if it is not fully charged.
How do I know that my device will work with the PSU?
First you need to determine the amount of energy that your device requires. This requires some research on
your part. Either consult the user manual for your device or check online.
