It’s ok. Doesn’t have a long battery life. Did work while I was out riding and needed some air. Won’t have to use CO2 cartridge anymore.

Great air pump works great for airing up bike tires the kids love it

My idiot self bought this thinking it'd be great to have in the glove box in case of emergencies. However, it's made (and advertised as being) for bikes - not cars. That being said, it does a great job with bike tires or other small inflatables. I like that it recharges via USB-C and has had enough power from a single charge to inflate whatever I throw at it - from bike tires to beach balls.

Pros:CompactCharges quickly.Easy to use and pick your tire type/target like bike, sports balls, car.Cons:Battery dies quickly even when not in use.

Bottom line up front: This is a great little pump. The issues I'll talk about are pretty minor.First, the good: I've used this on both Schrader and Presta valves, and it works on both (haven't tried the ball inflator, but have no reason to think it wouldn't work). It is surprisingly fast--much faster than those old hand-held pumps your grandfather and I used :). Small and light weight, charges from a USB charger (not included, but you probably have several).My quibbles: The instructions are in small print (not as bad as some I've seen), and sometimes unclear. The parts list says there is one rubber "seal ring", whereas there are actually two. The parts list also fails to mention what the later instructions call a "valve core" (it's really a piece of brass that pushes down the core in a Schrader valve). Plus the pictures in the parts list are so small that they don't really serve to identify the smaller parts.There are two ways to use the pump: with or without the six inch hose. The hose has a quick-attach fitting (works directly with a Schrader valve, or you can use it with the provided Presta valve adapter). I found it easier to use with the hose, although if you're super-concerned about weight, you can just use the pump with what the instructions call the "valve body", "valve cap", and seal ring (and the "valve core" if you're using it on a Schrader valve). The seal ring is easy to insert into the body, but hard to get out. If all your use cases are Schrader or all Presta, that's fine, but if you have some of one and some of the other, it's a bit of a nuisance. I also had a little trouble getting a good seal on a Presta valve with this mechanism; the tube + adaptor worked much better in that situation.Buttons: The '-' button is used to select among bike, motorcycle and ball uses. (You could use it on an automobile tire, but it would likely be slow and possibly overheat.) It is also used to reduce the PSI setting, but only after you've pressed the '+' button for several seconds to change the mode. The pump will automatically shut off once the PSI setting is achieved (and you can turn it off manually).Timing out: The instructions say the pump will turn off after two minutes of non-use. It's more like one minute. Very minor inconvenience.Accuracy: The seller's description claims a 1 psi precision, and the instructions claim a 2 psi accuracy. If you understand the difference between precision and accuracy, this makes sense, although I don't know why the readout shows 0.5 psi increments (there's no use in a readout that goes to five tenths if the precision is only to units).The protective case ("silicone sleeve") is nice, but probably unnecessary; and it oddly covers part of the heat dissipation port (my second photo).All my quibbles are minor. I think this is a neat little pump, and I am putting it to good use.

If I had a dollar for every time I've received a text from my husband saying "got a flat, be home late" I would have at least $16 by now.And while I know he has other things in his bag to fix those flats, he didn't have this, so I figured it was worth trying.Pictured from left to right are this pump, a manual pump, and a C02 cartridge set. Of the 3 options, this is the heaviest, but we're talking about ounces here so unless you're in a fairly serious competition, the weight difference probably won't impact your ride much.The advantage of this pump over the lightest option, the C02 cartridge, is that those cartridges are consumables whereas this is a flat cost (minus the small amount of electricity needed to keep it charged) and also this is filling your tire with just air. With the C02, depending on what type of sealant you use in your tires, you may have to empty and refill the whole thing when you get home after fixing your flat, and that's a PITA. So I would take this pump over those cartridges any time.The hand pump is great in an emergency if you have absolutely nothing else, but if we're being completely honest, you know it's never going to get your tire up to full pressure before your hands say "you can just walk because I'm not doing this anymore thanks anyway", it's just going to get you home with hopefully very few stops along the way to pump up your tire again. This pump will fully inflate your tire.So of the 3 options, this is my favorite despite it being the heaviest.As far as performance, there are the three things to be aware of.First, this will burn through half its charge filling a single tire, so you need to make sure you stay on top of keeping it fully charged unless you want to find yourself out on the trail with two flats and have to make your way home on two partially-inflated tires.Second, it is LOUD. We tested it in the garage and it was just... so loud. It might not seem as loud out in the open, but if Stealth Inflating is your thing, you won't get that with this.Third, it gets reeeally hot. So be careful handling it right after you use it. Because seriously. Reeeally hot.The display is easy to read, the pressure preset and auto shutoff features work as advertised, and it recharges quickly. All things considered, this is a great addition to our Things To Have When Things Go Wrong Kit.

This is an excellent portable pump to take for your small inflation needs. It’s the perfect pump for a bicycle tire. It also is great for pumping up basketballs, footballs, volleyballs, etc.It is extremely solid construction. There is nothing flimsy about this. It has excellent power. It is extremely loud, but I’ve used it to pump up bike tires and basketball‘s and it works wonderfully. You can set your PSI that you desire, and it will fill to that point and turn off. It comes with all the accessories that you need to pump up tires and Inflatable balls. It also has attachments for Schrader and Presta valves.It also comes with a nice silicone protective covering so that it doesn’t get scratched up. This is perfect for trail riders who need to quickly inflate their bike out on the road. It is quite expensive, but well worth it if you need rapid inflation.
