6. Setup
6.1 Charging the Pump
Before initial use, fully charge the pump's internal battery. You have two charging options:
- Using the AC Wall Adapter: Connect the AC wall adapter to the pump's charge port (12) and plug it into a standard wall outlet.
- Using the 12V DC Car Connector: Connect the 12V DC car connector (17) to the pump's charge port (12) and plug it into your vehicle's 12V cigarette lighter socket. For optimal charging, it is recommended to have the vehicle engine running.
The LCD display will indicate the battery charge level. A full charge typically takes a few hours.

Figure 6.1: The pump's built-in 6000mAh rechargeable battery can be charged via a wall plug or a 12V car power cord. It also features USB output ports for charging other devices.
6.2 Attaching the Hose and Nozzles
The pump comes with a flexible hose and 5 universal nozzle attachments to fit various inflatables.
- Identify the correct nozzle for your inflatable item. The pump is compatible with most high-pressure inflatables such as stand-up paddle boards, yoga balls, inflatable boats/kayaks, air mattresses, pool floats, inflatable sofas, and tents.
- Attach the chosen nozzle to one end of the inflation hose (13). Ensure the plastic ring on the nozzle is correctly positioned for a secure, airtight seal.
- For inflation, connect the other end of the hose to the Inflation Inlet (11) on the pump by screwing it on securely.
- For deflation, connect the hose to the Deflation Outlet (14) on the pump by screwing it on securely.
