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.

Charging methods

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.

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 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.

Instructions

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 off. It is recommended to keep the AC output power switched off when not in use, since there a small amount of power will be consumed while it is left on.
• Disconnect after use and turn off 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 specifications table for the maximum loads allowed on each socket).
• Disconnect after use and turn the main power switch off. 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.

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.

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 first 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 fire, 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 field. 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 flammable 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 off. It is recommended to charge the P750 every 3 months to prevent aging of the internal battery.
