Button A is the master switch. Press Button A to turn on the power or to shut down the output(s) when not in use.
The function is available no matter the Button "POWER ON/OFF " is activated or not as the following steps:
Firstly, press Button B to turn on the LED light into the LED light mode.
Secondly, double-click it to turn on the SOS mode.
Thirdly, press Button B back to LED light mode, then press it again, the light will be turned off.
Please make sure the button "POWER ON/OFF" is activated before pressing
Button C to tum on; Press Button C to shut down the output(s) when not in use.
Please make sure the button "POWER ON/OFF" is activated before pressing Button D to tum on; Press Button D to shut down the output(s) when not in use. The USB-C cable of different devices needs different endorsements of corresponding protocols, if the USB-C port doesn't work, try to use the AC adapter to charge.
Please make sure the button "POWER ON/OFF" is activated before pressing Button E to turn on; Press Button E to shut down the output(s) when not in use.
T300 utilizes an internal cooling fan to ensure the product is operating within the appropriate temperature range, T300, when it experiences a higher output load, will automatically turn on the fan during discharge or recharging, the fan may operate intermittently to keep the internal temperature within operating range.
The fan will likely start when the AC circuit is activated to ensure proper operation.

Note: DO NOT CONNECT DEVICES VIA AC OUTPUT WHILE CHARGING THE T300.
CHARGING T300: It is recommended to disconnect the T300 when fully charged and fully charge T300 every 3 months to maintain the health of the battery pack.
Do following: Check the input charge cable. The port will be efficient when the input charge cable meets the specification outlined in the GENERAL SPECIFICATIONS section. Note that when you first plug in a power source, whether it's a solar panel or a wall charger, the T300 may take a minute to detect and adjust its charge circuitry before it starts drawing power from the source.
It will take 6-7 hours to charge fully by using the AC adapter we provided.
Use the Car Charger we provided to charge this unit. The full charge time takes 7-9 hours. When the LCD display shows the battery power of 100%, it indicates that this unit is fully charged.
Select the type of outlet required by pressing the Output ON/OFF Button C/D/E. The output port will NOT function until the appropriate button is pressed to activate the port. When activated, the LCD display will turn on and provide details on the charging output, indicating that the output(s) are active. The LCD Screen will automatically shut down when no outputs are activated.
The advanced battery management system of the T300 allows it to charge a connected device via DC output & USB output While charging the T300.
If an overload condition occurs on the OUTPUT port, T300 will: Automatically turn off AC Output power. The white indicator light of LCD Screen is still illuminated. DC OUTPUT Status is still the same status as usual.
