Complete use, valve and care support for the GR-133P high-pressure rechargeable pump.
Air tents, SUP boards, boats, mattresses and compatible TPU products up to 22 PSI.
Recharge for about 3–4 hours; store with at least 50% battery charge.
Inflation and deflation with multiple nozzle fittings for common valves.
Inflating an air tent
- Place the pump on level ground near the tent valve.
- Thread the hose directly onto the tent valve; a separate nozzle is usually not needed.
- Set the tent maker’s target pressure—for example, 7 PSI—then start.
- The pump stops automatically at the selected pressure. Disconnect the hose and close the valve cap.
Deflating an air tent
- Open the tent’s deflation valve cap.
- Use the extended nozzle where needed so it reaches into the valve correctly.
- Make an airtight connection, then start deflation.
- Fold or roll the tent according to the tent maker’s packing instructions.
FAQs & troubleshooting
Can it inflate more than tents?
Yes. It can also inflate compatible SUP boards, boats, air mattresses and TPU drop-stitch products requiring no more than 22 PSI.
Why is air leaking around the valve?
Check that the hose is threaded or locked fully and that the connector is clean. For some Takibi or Dupont-style mattress valves, a thin 2–3 mm white O-ring from the accessory set may provide a better seal.
Does it inflate and deflate?
Yes. Move the hose to the correct port for the task and keep the valve connection airtight.
What if it does not start?
Recharge first, then check the power button and make sure the air vents are clear. Send us a short video if the issue remains.
How should I store it?
Keep at least 50% battery charge before storage and place the pump in a dry location.

More questions
How loud is the GR-133P?
Operating noise is no more than 75 dB under normal use. Put the pump on stable ground to reduce vibration.
Does it have product and battery documentation?
Product documentation includes CE, RoHS and FCC, plus battery MSDS and UN38.3 transport documentation. Contact support if a document is needed.
How long can it run for a 16 m² tent?
As a reference, inflating a 16 m² tent takes about 10 minutes. The actual result depends on the tent, valve and selected pressure.
