Rechargeable Two-Stage Air Pump with 6 Valve Adapters – 10 PSI
Fast, Convenient Inflation Without a Power Outlet
Make inflating compatible outdoor gear easier with this rechargeable two-stage air pump, designed for convenient cordless inflation wherever you need it. The GR-633 combines high-volume airflow for quickly filling larger inflatable products with a lower-volume, higher-pressure stage for reaching the required pressure.
Its built-in 2,000 mAh rechargeable battery eliminates the need for a constant connection to a power outlet, making it practical for use at the campsite, beside the water, or around your storage area.
Two-Stage Airflow for Faster Inflation
The pump uses two airflow stages to handle different parts of the inflation process. The high-volume stage delivers up to 500 L/min for quickly filling an inflatable, while the second stage provides 40 L/min for controlled pressure building.
- Two-stage airflow: 500 L/min + 40 L/min
- Pressure range: 0.5–10 PSI
- Digital pressure display
- Preset pressure control
- Automatic shut-off at the selected pressure
- Inflation and deflation functions
Preset Pressure & Automatic Shut-Off
Set the desired pressure using the digital control panel and let the pump handle the inflation process. Once the preset pressure is reached, the pump automatically stops, reducing the need to repeatedly check the pressure manually.
The simple controls make operation straightforward: connect the appropriate hose and adapter, select the required pressure, and start the pump. The pump automatically changes between its two airflow stages as it works toward the selected pressure.
Designed for Outdoor Inflatable Gear
The pump is suitable for a range of compatible inflatable products, making it useful beyond a single type of equipment. Recommended applications listed in the product presentation include:
- Inflatable boats and dinghies
- Kayaks
- Compatible drop-stitch floors
- Firm camping mattresses
- Small air tents
The appropriate valve adapter and required pressure should always be confirmed for the specific inflatable product before use.
Cordless & Portable Design
With a compact 0.9 kg body and built-in rechargeable battery, the pump is designed to be easy to carry and convenient for outdoor use. It charges through USB-C, allowing it to be recharged without relying on a traditional 12V socket.
