HOTO Dual-core intelligent inflator QWCQB002 gray

I paddleboard. I have multiple paddleboard pumps. This pump always comes with me. It is my slowest pump. Why do I always take my slowest pump? It is the best pump I know of that has both a battery and can run off 12v DC power (from a car). I always want the security of knowing I can inflate and deflate my boards without having to worry about the battery health and capacity. To be honest; I usually bring two pumps (I’m always inflating/deflating multiple boards… I bring my fastest battery only pump as well). But that should not detract from this excellent device and how indispensable it is to me.

Works great for air mattresses. Pump was 100% full battery and pumped a single mattress and then double (double thick too) in 1:30 and 3:30 respectively. BUT it ran out of battery trying to fill the SUP. Ran out around 6psi. Lesson: connect via portable power to dc when pumping up SUP. Not yet tried for truck tires but expecting it will work great.

I was surprised that this pump was able to inflate the Tesla Cybertruck's 35-inch tire from 36 psi to 50 psi within 5 minutes. It completed inflating 3 tires in 15 minutes without overheating, while another portable Fantik X9 took 13 minutes per tire. I originally purchased this to inflate the Cybertent (buying a separate valve adapter is required) and I thought that I might have to buy another stronger pump for airing down and airing up the truck tires for frequently going off-roading, but to my surprise, this pump was all I needed. The original unit had an error where it stopped showing the battery level indicator after plugging into the 12V cigarette lighter, so I contacted customer service for a warranty issue. They were a little slow to respond at first, but they finally did send a replacement. For that, I'm confident in highly recommending this pump after much field testing, and I know that the company stands behind its product after sale. I'm very happy with the purchase and am using it quite regularly. Warning: if you are using the cigarette lighter socket method, the output rating must be 120W max for it to work with inflating vehicle tires. Otherwise, a 60W max works when I use it to inflate the tent.

Wow, I’ve never been this disappointed with a product before. I have the HOTO drill and it’s been great. I’ve barely had to recharge it. I also bought their battery-operated wine opener (which I still don’t understand why they didn’t make rechargeable via USB), but this air pump? This was the last straw. I used it once, and that was it. After that, it just stopped working. I left it charging overnight, and the battery level didn’t move at all. I tried different chargers and power adapters, but nothing worked. They only include a USB-A to USB-C cable, which isn’t much help if the device itself won’t charge. Honestly, I’m super disappointed, especially considering this thing costs over $200. My friends got basic air pumps on Amazon for like $30, and they were able to inflate their kayaks without even plugging them in. Meanwhile, I couldn’t even deflate mine, even with this thing plugged into my car. I don’t usually write reviews, but this was such a letdown I had to. I really can’t recommend it.

Outstanding Customer Service! Luna of the Team rescued me from missing an upcoming kayak trip trip -- i had a malfunctioning unit -- by shipping out a replacement in quick time. Love the pump & the Team! Thx!
