LCD battery symbol and failure code
Safety Instructions
The LCD Battery Display indicates the Battery level. There are 5 segments
of the battery, approximately 20%-40%-60%-80%-100% capacity. During using,
segments will disappear from the display. When charging your PPS, you will
notice a battery segment blink at 1 second interval, which indicates the current
charge status and the number under INPUT shows the real-time charging
power. Once it is fully charged, all battery segments will be lit and remain solid.
When the product breaks down, the fault code is displayed at the input or
output power display, such as "E01"
Note: Charge your PPS when there is only one battery segment!

4
the power indicator and LCD screen will be lit up. When the main power switch
key is turned on, the product can be charged and the AC/DC key can be turned on.
2. After the main power button is turned on, you must turn on the AC/DC
key when using this product to power your device. Press the AC/DC button
for 2 seconds to open the corresponding AC/DC output. Then you will nd the
corresponding LED green indicator next to AC/DC button will be lit up. After 15
seconds of use, the backlight of the display screen is closed and any key is
pressed to activate the display screen.
3. If the main power button is turned on, and the AC and DC switch button is
not turned on, then the product will be automatically shut down after 10 minutes
without charging.
4. To save battery power, turn off the product when you are not going to
use it for a long time. Press the AC/DC button for 2 seconds to close the
corresponding AC/DC output. Long press the main power button for 2 seconds
to shut down, then AC and DC have no output, and the display screen and

period.
How to charge this product ?
Note: Please charge the product before use; Turn on the product before
charging.
There are 3 ways to charge the product, using AC adapter, solar charging
cable or car charger. First, you need to determine the input source and select a
charger accordingly. Then, connect the charger to the input port of the product
and it will be charged. When the product is being charged, the LCD battery
would ash on the LCD screen. When the product is fully charged, the LCD
battery would stop ashing.
A. Charge with Solar Charging Cable
Place your solar panel somewhere that it can receive direct sunlight and

5
abundant sunshine.
The solar panel open-circuit voltage should be 14-40v.The maximum
charging power of this product is 125W.
Connect the solar panel and the product using solar charging cable. Make
sure that the solar charging cable is correctly connected and forming a solid
contact with the input port of the product.
This product is built-in advanced system control circuit module. When the
battery is full charged, it will stop charging automatically.
B. Charge with AC Adapter
Please use the AC charger equipped with this product to charge. You can
know the charging status of this product through the LCD screen. This product
is built-in advanced system control circuit module. When the battery is full
charged, the product will stop charging automatically.
C. Charge with Car Charger
Please use the original car charger. Insert one end of the car charger to the
car cigarette lighter and insert the other end to the input port of the product. The
LCD battery will blink to indicate that the product is being charged normally.
Note: A car with 12V starting battery can't charge this PPS fully, but a car
with 24V battery can charge it fully. You'd better start the car when you charge
this PPS.
How to Jump-Start a Car
Precautions before jump-starting a car:
1.Make sure the engine displacement of the vehicle (or other motor vessels,
here take a car for example) is no more than 4L.
2. Make sure the PPS power is over 60% (four battery segments on).
3. Make sure the clamps on jump-start cable is not broken.
Steps:
1. Clamp the red clip to car battery positive pole and the black clip to the
battery negative pole.
2. Plug the other end of jump-start cable into your PPS.
3. Turn the key to start your car as normal.
4. After starting, remove the cable from this product rst, then remove red
and black clip.

FAQ(Frequently Asked Questions)
Unpacking
Q1.How do I know if my PPS is charged?
To check the charging state of your portable power supply, refer to the LCD
Battery Display. When lit up, you will see a battery outline with ve segments,
indicating the current charge level. You can turn on the Battery Display by
pressing the Master Power Button. It is OK to use your PS5B even when it’s not
fully charged.
Q2. How do I know if my device will work with the PPS?
First, you’ll need to determine the amount of power your device requires.
This may require some research in your side, a good Google search or
examining the user guide of your device should be enough.
Second, you will need to check the capacity for the individual output ports.
For example, the AC port is monitored by an inverter that allows Max.300W of
continuous output power. This means if your device needs to work over 300W
power for a long time, the PPS’s inverter will shut off automatically.
Q3.What’s Depth of Discharge(DOD)
To extend the service life and storage time, the DOD is set around 90%, which
is 90% of 400wh, to keep the battery from damage due to over discharge. Then
the product real working time is calculated as : Working time =400wh*0.9÷P (P:
Power of connected electrical devices)
Before opening the package, please check if the packaging is damaged.
After unpacking, please check if product appearance is damaged or any part is
