Review on Efficient Electric Portable Air Pump: Quick-Fill, 3 Nozzles, Inflator/Deflator for Various Water and Air Gear - Ideal for Pool Toys, Air Mattresses, Rafts, Boats, and Swimming Rings - 110V AC/12V DC by Monique Lopez

I have to say I just don't approve of this pump in the end. Admittedly this is the only pump of this type I have ever tried so I don't have a direct comparison but I really hope this is not the standard for this type of pump. The noise level is very loud, to the point where I should just call it a name and say it's not an ideal pump for indoor use. I almost wonder why it doesn't come with some kind of damping layer to muffle the loud, harsh sound. As a kid, I knew that cigarette-lighter powered pumps were pretty loud too, but it was an engine-like noise that was mostly quiet enough to shout out loud. Forget those who talk to you a lot while this is happening. Worst of all is the frustrating sound of solid particles, like the sound of your vacuum cleaner hitting a patch of crumbs. It constantly makes that odd noise during use, to the point where you have to wonder about the large intake and why it's so prone to dust getting into its gizmos. I know I said that's the worst thing, but I guess that's not true either, as the focus is on the desired task of airing things out, which is almost shockingly slow. Again, maybe this is the standard for this type of pump, and maybe you just need a completely different type of pump. I can neither refute nor confirm that. All I know is that this device is pretty awkward to use. But I think it technically gets the job done, although it takes a while and you might end up sitting there blowing your thing and trying to master the perfect angle. Compared to the hard way, I'm not sure which is worse.
