Valwix 20PSI High Pressure SUP Air Pump The Whale stands out for several reasons. It offers up to 20 psi dual-stage inflation with an auto stop function at the target pressure. This means it supports high-pressure inflation for most branded inflatable paddle boards, providing higher rigidity and stability. Additionally, it has a powerful automatic cooling system that starts off at the first minute, allowing for a longer constant working time. With this pump, you can pump up to 3 paddleboards in a row. It also has active overheat protection at 158 Fahrenheit, ensuring a long lifespan.

Some small improvements in the Valwix Whale Pump can save you a big headache. For example, it comes with a 9.8ft long power cord, so you no longer have to move around the SUP to find a car socket. It also includes an extra cigarette lighter plug for easy replacement after a long time of wearing. With its 7 valve adapters, ranging from 0.5 - 20 PSI, you can use it for almost all of your inflatables. Additionally, it has a screen backlight that helps you better observe real-time pressure. The pump features an ergonomic carry handle and comes with a storage bag, making it easy to fit in your trunk.

Valwix provides warranty beyond Amazon's 30-day return window. They offer replacement/refund for defective or damaged products within 1 year of the warranty period. For any issues, you can contact the seller directly.

The Valwix Whale Pump offers active cooling technology, allowing you to inflate three boards up to 20 PSI in a row. It automatically cools down from the first second of inflation, providing a 45% longer continuous working period compared to most electric SUP pumps on the market. This pump doesn't require you to wait, so you can get right to the fun. It has a dual-stage, auto-off inflation feature. The first stage provides maximum speed at 350L/min, while the second stage offers maximum pressure at 70L/min. It takes approximately 8-10 minutes to inflate one iSUP. The pump automatically shuts off at the desired pressure, ensuring accurate inflation without the need to keep an eye on it. It can completely deflate the SUP into a sheet in 3 minutes for easy packing and storage.

This pump is connected to a car's cigarette lighter or a power station with a 12V outlet. It has a real-time digital display and a target pressure function that ensures the board stays within the recommended PSI range, offering a precise level of rigidity and prolonging the board's lifespan.

The Valwix Whale Pump features a sand-proof mesh inlet and enhanced ventilation. A metal mesh blocks sand, grass, and dirt out of the air intake, ensuring maximum airflow. This improves cooling efficiency by 30% and reduces the chance of motor burnout by 57%. The pump is designed to last a lifetime.

It comes with a 7-valve set that works for both high and low-pressure inflatables. The set includes an H3 (Hokey-Roberts/ HR) nozzle for most branded paddle boards, a Boston nozzle for kayaks and inflatable boats, and a round/pinch nozzle for pool floats, inflatable pools, air mattresses, tents, etc. This pump is CE/ROHS certified to be safe and made of solid materials.

Unfortunately, the Valwix Whale Pump is not compatible with bike/car tires. It mainly serves for larger inflatables.

The Valwix Whale Pump needs to be plugged into your car's 12V power supply while inflating.

If your raft has a Leefield valve, Valwix provides customer support for this. They will assist you in finding an adapter for Leefield valves if necessary. You can contact them through Amazon message or their after-sales mailbox.

When it comes to knowing if your paddle board is fully inflated, you can tell if it is underinflated if it feels soft and your feet sink into it.
