SUP pump 20 PSI dual stage

The AstroAI HT-782 is a 12 V DC electric pump built for inflatable stand-up paddle boards, kayaks, boats and tents. It delivers a first-stage flow of 350 L/min and a second-stage pressure up to 20 PSI, inflating a typical board in about 10 minutes. A digital LCD screen shows pressure to 0.01 PSI and stops automatically at the preset target.

Paddlers needing car-powered inflation

This unit suits anyone who wants fast, hands-free inflation from a vehicle 12 V outlet using the included 11.2 ft power cord. It is not for users who require AC mains operation, battery-powered portability away from a car, or pressures above 20 PSI for specialised high-pressure craft.

350 L/min first-stage flow rate

The defining specification is the dual-stage design: 350 L/min at low pressure for rapid volume, then 70 L/min at high pressure to reach 20 PSI. This combination decides whether the pump can handle your board volume and pressure target within the typical 10-minute window.

Questions about this item

How do I install the AstroAI HT-782 pump and what step do people often miss?

Plug the 11.2 ft DC car power cord into your vehicle's 12 V cigarette lighter outlet, attach the 3.3 ft high-pressure hose and choose the correct valve adapter with the matching O-ring size (3 mm, 5 mm or 6 mm) to prevent leaks, then set target pressure on the digital LCD screen.

What maintenance or replacement will the AstroAI HT-782 pump need later?

Inspect and replace the three included O-rings (3 mm, 5 mm, 6 mm) if they show wear or cause air leaks, check the 12 A fuse in the car power cord if the pump stops powering on, and clean the plastic housing and valve adapters after each use.

What limit appears first during sustained use of the AstroAI HT-782 pump?

The dual-stage design shifts from 350 L/min high-volume flow to 70 L/min high-pressure flow, so extended inflation sessions are limited by the slower second-stage rate and the 12 V DC power draw from the vehicle outlet.
