Dr.Meter 4000mAh Rechargeable Air Pump for Inflatables Ultra Fast Inflator

This product is great, I have a inflatable kayak and we were able to inflate it fast. We didnt need to pump or blow it up. We just left the inflator do its job. Easy to recharge. Great size to keep stored in your car. Absolutely buy this!

If I could give this air pump more than five stars, I would. In a nutshell: + powerful air pump + incredibly long-lasting charge + small/easy to travel with + rechargeable & cordless! + fits multiple sizes + inflates & deflates products quickly + relatively quiet (considering it’s an electric air pump) + amazing price I just broke out my air pump for the first time this summer since using it last summer and it still had a 75% charge to it. Even after inflating my raft AND deflating my raft, 3/4 charge lights were still on. I do wish I could get an additional attachment for my paddleboard, but otherwise, I absolutely LOVE this product!

We have had our HT-420 for two years now. We use it to (quickly) pump up inflatable kayaks (about 15 kayaks per charge, but probably more) and to inflate and deflate our rooftop tent air mattress. We find its vacuum (deflate) setting to be as powerful as its pump setting. Love that it’s rechargeable too (no separate batteries)—light bars tell you how much charge you have left. We just love this little guy—in fact I think I’ll buy another in case it ever gets discontinued

I bought this mostly to save time and effort blowing up my Sea Eagle 330 inflatable kayak no matter how far away I would be from cars or electric outlets. I already have an inflator that can run off my car battery through the cigarette lighter (HT-196A), but I worry about being in the boondocks and running down my car battery so it won't start. This HT-420 is exactly what I need. I received this inflator a month ago and charged it up, but I didn't get around to pulling out my kayak until yesterday. Without charging it up, again, I used the HT-420 in a dry run to make sure it would do what I want before I take out my Sea Eagle 330 this summer. When I started, I had three of the four LEDs lit. When I finished inflating the three main chambers of my kayak, the unit still had two LEDs lit. My guess from that is that I might be able to blow up my kayak three times or so from a full charge, especially if I don't completely deflate it between times, but just enough to fold it and fit it back into my car trunk. Also, the pumping took less than 7 minutes, even though I goofed first and pumped up a chamber without using the one-way valve on the Sea Eagle 330. So, inflating might take only about 5 or 6 minutes from fully deflated for all three chambers when I do it right. As pointed out by other reviewers, the HT-420 will not pump up the chambers to full pressure, but it sure gets it close enough that to top it off shouldn't take much effort with the foot bellows that came with the kayak. Pros: 1) Any USB source can charge the unit (USB cord included), even an AC adapter. 2) This pumps up my kayak faster than I can with any manual pump I own. 3) This doubles as a USB power bank for recharging cell phones and such. 4) This can also pump out air from inflatables to help store them away faster. Cons: 1) It must be held against the item being inflated, because it has no hose, only the nozzles. I consider this nearly a nonissue. I'd gladly hold this in my hand for a few minutes to save all that pumping with the foot pump. 2) It doesn't have enough power to fully inflate some inflatables (but it will come close). 3) It does seem to take a long time to charge the pump. I didn't time it after I used the pump, but I know that it took over an hour to charge the pump back up with my AC to USB adapter from two LEDs to all four LEDs (full charge). I'd still gladly live with that, too, for the convenience of not being restricted to where I can use the inflator. I'd gladly buy this again. I like it! Pictures: 1) My Sea Eagle 330 after I pumped it up as far as the pump would get it. 2) The HT-420 showing only two LEDs lit after it pumped up the Sea Eagle 330. 3) Three LEDs lit while I was charging the pump with my AC adapter. When all four LEDs are no longer blinking, it's fully charged. Enjoy!

This air pump works well. There is one peculiar design issue. The power switch is a simple toggle switch. It is easy to reach and flip on/off. Maybe too easy. When I opened the box, there was a plastic cover taped over the switch to prevent it from turning on during shipping. Great. But what's supposed to keep it from turning on when packed for a camping trip? I'm trying to keep the protective plastic cover, but I don't think it will last long since it's just a piece of tape holding it in place. When designed, it should have had a more protected switch.

This pump works wonderfully! We went camping for two nights. It filled a queen & two twin mattresses, refilled them the second night, inflated 4 tubes for the river, and deflated the mattresses. We still had over half the battery left. It’s super compact and easy to store.

This is a mighty little pump. I love that you can charge it and take it On The Go. We take it on the pontoon boat and inflate our inflatables when we’re already out on the water so we needed something just like this. I’ve used it several times to inflate fairly large items and it does the job wonderfully.

Not worth the money bought in may blew up 3 rafts went to deflate in early September would not charge

Pumped air mattresses super fast. It can also be used to deflate air mattresses and as a power bank. Nice little gadget.

Bonne qualité et livraison rapide.

It blew up one of our large double hight airbeds in less than 5mins. Used less than one bar. Didn't even get warm. It will be a great asset when camping. Will also be able to charge my phone with it. 😊
