Question 1

How long does the battery last, and can I fully inflate my SUP wirelessly from flat?**

Accepted Answer

The battery is best for topping off a board or inflating small items. It can add 5-7 PSI to a partially inflated SUP wirelessly. However, for a full inflation from completely flat, you'll want to plug it into the 12V car charger. Many users on Reddit recommend using the wireless mode only for the final top-up or for portable uses like inflating an air mattress at a campsite.

Question 2

I see it says “20 PSI.” Is that accurate, and how long does it take to get there?**

Accepted Answer

Yes, it can reach 20 PSI, but it’s a slow crawl from about 15 PSI to 20 PSI. For most 10-12 foot SUPs, which need 14-18 PSI, it works great and will auto-off at your preset. We recommend setting your target between 15-16 PSI for the best balance of speed and performance. The full 20 PSI is more of a safety buffer than a daily-use target.

Question 3

Does this pump work with different brands of SUPs and air mattresses?**

Accepted Answer

Absolutely. It comes with multiple adapters, including a Halkey-Roberts style valve for most SUPs (like iRocker, Tower, etc.), a Boston valve for thick air mattresses, and a needle for balls. The pump automatically senses if it's in high-pressure (for boards) or high-volume (for mattresses) mode when you attach the right head.

Question 4

A few reviews say the pump broke after a few months. What’s your return policy if that happens?**

Accepted Answer

We stand behind our product. If your pump fails due to a manufacturing defect within 90 days, we offer a full refund or replacement. After that, our standard warranty covers functional issues for up to 12 months. Please contact our support team with your order number, and we’ll get you sorted quickly. Many TikTok users have praised our customer service for being very responsive on this.

Question 5

Is this pump very loud? I’m worried about bothering my neighbors at the campsite.**

Accepted Answer

It’s a bit louder than a corded desktop fan, but much quieter than most gas-powered pumps. It’s certainly not silent. We find that using it on the high-volume "mattress" setting is very fast, so the noise is short-lived. For morning SUP sessions by a lake, it’s usually not an issue, but we recommend giving a quick heads-up to nearby campers if you’re inflating at dawn.
