Product Introduction
Thank you for purchasing this product. The HT-790D is an intelligent DC electric pump with a preset pressure LCD screen, which can be used for inflatable tents, SUPs, etc. Thanks to the intelligent pressure system, for example, if a pressure value is preset, when the pressure reaches the preset pressure value, the pump will automatically stop inflating.
This product also supports deflation. When the inflatable product is not used, you can use the air pump to empty the air inside for folding and storage.

USB Charging Output Operation
In standby or power-on state, connect one end of the USB Cable to the USB/Charger Port on the pump and connect the other end to a USB port on your phone or other digital products. (As Fig 1)
Description of Fig 1: Figure 1 illustrates connecting a USB cable from the pump's USB output port to a smartphone.
Charging
Please use a Type-C USB cable with this product for charging. When charging, the indicators will flash. In the fast charging mode, the red indicator remains on. Charging voltage is 5V/2A or 9V/2A and will be automatically identified. (As Fig 2)
Description of Fig 2: Figure 2 shows the Type-C charging port on the air pump and the connection of the Type-C cable.
Make sure the battery is fully discharged before the first charge. After the battery is discharged, if the internal temperature is too high, it is recommended to cool it down before charging. Do not leave the electric air pump in a state of no electricity for a long time.
Inflation Operation
1. Press and hold the power switch for 3 seconds to enter standby state. Connect the end with the flexible conduit adaptor of the hose to the air pump inflation inlet (1), and twist clockwise to tighten it (As Figure 3).
2. Connect the other end of the hose with the air nozzle that matches the air bag, and insert the inflation valve of the air bag. Turn it clockwise to fix it (As shown in Figure 4).
Description of Fig 3: Figure 3 shows the connection of the hose adapter to the air pump's inflation inlet.
Description of Fig 4: Figure 4 shows the connection of an air tap (nozzle) to the hose and the inflation valve of an air bag.
3. Press the pressure unit switching button [PSI/BAR] and select the unit you need.
4. Press the pressure increase button [+] or decompressing button [-] to set the desired pressure value.
5. The pressure range is from 0 to 20 PSI (1 PSI = 0.0689 bar = 6.89 KPa).
6. Upon completion of the above steps, press the power on/off button [ON/OFF] to start inflation; or plug the cigarette lighter into the 12V DC socket, the display lights up, press the On/Off button [ON/OFF] to start inflating.
7. In the process of inflation, you can press the pressure increase button [+] or the pressure reduction button [-] to increase or decrease the pressure value. Press the pressure unit switching button [PSI/BAR] to switch between the units, and press the power on/off button [ON/OFF] to stop.
8. When the pressure reaches the set value, the air pump will stop working automatically.
9. Upon the completion of inflation, it will turn off automatically without other operations within 2 minutes.
10. After pulling out the DC plug, please detach the hose from the air pump and air bag and store it.
Notice: The factory set pressure value of the air pump is 20 PSI (1 PSI = 0.0689 BAR). For subsequent uses, the set pressure value from the last use will be displayed by default.
Deflation Operation
Press the power switch button of the air pump to start deflation until all the gas is discharged, then the power can be turned off to stop the deflation.
Description of Diagram: Two diagrams show the air pump connected to an inflatable item for deflation, illustrating the process.
