Product Description
The Amptron® P750 is an extremely compact yet safe and powerful Lithium portable
power solution. It stores 750Wh of energy, which provides the equivalent usable
energy of about a 12V 100Ah AGM battery. With its convenient carrying handle the
P750 provides a convenient portable energy solution for activities like camping,
outdoor photography, mobile workstations, charging of batteries, a mobile option
to power equipment and much more.
The P750 can also be used as a dual battery system alternative, with its capability of
being charged from multiple charge sources including mains charging, solar, and
DC-DC charging through either the Cig plug adapter or compatible 15A Anderson
DC-DC charger (*** sold separately).
The P750 has a rich set of output interfaces. It provides an AC output port powered
by a 300W pure sinewave inverter, 2 x USB TYPE-A and 3 x USB TYPE-C ports, and a
12V Cig plug.

How to use a motor vehicle to charge?
Follow the steps as shown below:
1. Using the car cig charging adapter, plug one end of the cable into the
charging port on the P750. Plug the other end of the car cig charging cable into
the car cigarette lighter socket, then run the vehicle to start charging.
2. Using the optional 15A Anderson plug DC-DC charger, plug the one end of the
cable into the charging port on the P750. Plug the Anderson end of the cable into
an Anderson plug in the vehicle, then run the vehicle to start charging.
Note: It is recommended to install a voltage sensitive relay (VSR) to prevent the
Anderson plug DC-DC adapter from draining the starter battery.

Car charging (50W) 15 Hours
60W solar panel 12-20 Hours
100W solar panel 7-13 Hours
500W solar panel 1.5-3 Hours

How to use a solar panel to charge?
1. Using a compatible solar panel purchased from AMPTRON® (optional accessory),
unfold the solar panel and face it towards the sun. Then connect the Anderson
plug adapter cable to the input port on the P750, and the solar panel to the
Anderson plug adapter.
2. Using a solar panel purchased from a third party, a solar charge controller with an
output of about 16.8V should be connected. Alternatively, contact Amptron to
check if your solar panel is compatible to be connected directly without a charge
controller, or Amptron can provide you with a compatible solar charge controller.
The maximum supported solar power is 500W. Place the solar panel and face it
towards the sun, then connect the solar charge controller to your solar panel as
well as the one side of the Anderson plug adapter, and connect the other end of
the adapter to the input port on the P750. * Please pay attention to the +/- poles.
Note: It is recommended to remove the solar panel or turn o the solar input once
the battery is fully charged.
How to use the mains supply to charge?
Follow the steps as shown below:
1. Plug the one end of the adapter into the charging port on the P750.
2. Plug the other end of the adapter plug into the mains supply socket to start
charging.
3. It is recommended to remove the charging cable after the battery is fully charged.
Do not use a 3rd party adapter to charge this product.

How to use P750 to provide AC output?
• Turn the P750 power switch on.
• Connect the AC load device into the 230V AC output interface. (The power load
must not exceed 300W).
• Click the AC output switch to turn on the AC output. Electrical equipment
connected to P750 can then be used as normal.
• Click the AC output switch again to turn the AC power o. It is recommended to
keep the AC output power switched o when not in use, since there a small
amount of power will be consumed while it is left on.
• Disconnect after use and turn o the main switch.
How to use P750 to provide DC output?
• Turn the P750 power switch on.
• Connect the DC load device to the corresponding DC output socket. (Please refer
to the specications table for the maximum loads allowed on each socket).
• Disconnect after use and turn the main power switch o.
You can use both AC and DC at the same time, but the load should not exceed the
upper output limits.
Cigar lighter output
• Connect a cigarette lighter cable from the P750 to your device.
• The OUTPUT icon on the right side of the display will illuminate.
Instructions
DC 12V output
The device has two DC 12V pin outputs.
Connect the DC 12V pin connector, such
as an LED light, to one of the two outputs.
Both DC outputs are the same. Both
outputs can be used at the same time to
provide additional power.
The OUTPUT icon on the right side of the display will illuminate.
USB 5V output
Connect one end of the USB cable to the USB output connector and the other end
to the corresponding phone or digital device for charging. The P750 has three
independent USB TYPE A outputs, each with an output current of 2A, plus 2
independent USB TYPE C outputs with 3.6V ~ 20V voltage, a maximum output
current of 3A.
The OUTPUT icon on the right side of the display will illuminate.

BMS protection system (error code display) Precautions
Read the following carefully before using this product. Improper operation of this
product may damage the P750, and the devices connected. Always check the
power and voltage input of any device prior to charging with the P750.
• Make sure you fully charge the P750 before using for the rst time.
• Do not connect a DC charging source via the cigarette outlet to charge the P750.
• Charge using ONLY the charger that comes with the P750.
• During charging, never touch the metal inside the output socket.
• Do not connect the P750 AC output to any AC mains connection.
• Never immerse the P750 in water. When not in use, kept in a cool and dry
environment.
• Never place a P750 near a re, heater or in a high temperature environment when
in use or stored.
• Do not knock or throw the P750.
• Do not use the P750 in a strong electrostatic or strong magnetic eld. This will
damage the P750 safety protection device.
• Do not open the product or remove parts from the P750.
• Due to the large output power of the P750, when connecting a device, a slight
spark may occur. Therefore, do not use the P750 in a ammable or explosive gas
environment.
• The P750 AC output is a standard 220V sine wave voltage. This can be potentially
dangerous, and/or fatal if used incorrectly. Treat with caution to prevent electric
shock when using.
• If the P750 is not going to be used for a long period of time, turn the power
switch o. It is recommended to charge the P750 every 3 months to prevent
aging of the internal battery.
