I debated on getting one of those cheap cordless pumps made to be carried on your bike but I seldom get a flat while riding and mainly want to top off my tires. they tend to use 10psi or a bit less every two weeks from the 700cc 38 tires. I thought about getting the ryobi one it is only 29.00 without a battery and I had a couple though maybe too small. but at that price I wonder about the longevity. the milwalkie one was the second choice as I have batteries and charger at home bit I think it needed the larger amp batteries then the ones I have but the same charger. I have makita batteries and chargers so I went with it. at 99 it is the most expensive for 80 you can get the 12v version. you can set it to the psi you want but for some silly reason it does not have a trigger lock so you would be watching it at the time. thats a easy fix wit ha rubber band or such. but I tested it on a empty tire and it filled it to 70 psi in 50 seconds. tested it on a friends car tire that was down to 13pis filled it to 32psi took a few minutes. we topped off all the tires and the battery hardly took a hit. so for bikes a battery would last for months. I debated on putting a presta head on it but you usually have to push down o it to keep it in place I rather have it lock on.

Not saying that a cordless electric compressor isn't useful (I use one for topping up car tires), but if your routine use is adding 10 psi to your bike tires every couple of weeks, how is this an advance over a plain ol' track pump parked in the corner of the garage?

I know, it is digital so it must be better, right? Since I ride mostly for exercise I just consider airing up the tires as part of my warmup. Mindless enough task that I can give the bike a visual "preflight inspection" during the process.

true but my guts don't like it when I bend over a lot so with this I put it on the tire and in a few seconds its done not down to attach up then pump and back down. plus its so much faster to fill a empty wheel too. plus its fun. its not that much more expensive then a decent hand pump. I will use it once in awhile for other tires.

Can someone help me understanding the pricing of cordless tools? The above tool + battery sells for $99. They charge $89 for an extra battery and $59 for the bare tool. The proliferation of chargers is another issue: I have 8 power tool chargers, 3 are Dewalt they are becoming unmanageable. All of my bike lights are charged with a single micro USB charger; I have managed to stay away from batteries on them otherwise.

it can get crazy. I use makita and milwalkie. so I only need two chargers until I got this dinky little cordless makita saw then it needed its own charger. I like how milwalkie has so many tools one battery works for. I have this tool store that has yearly sales to buy batteries if I need them..actually the tool above is 99 without a battery. they make so much on batteries is why they do it the tools are a decent price but they make the money on batteries.

Heck, I use my floor pump for topping off the car tires as well. As long as you only have to put in a couple psi at a time, it's NBD.

less work than breaking the compressor out actually IME. I can't fault anyone for their tools and gadgets though, I have plenty.....just got a pretty full set of milwaukee 18v. The package deals are way cheaper than buying individually

I do pretty much think you should have a pump with you at any distance further than you are willing to walk home. Bring your C02, but have pump and patches and spare tube(s)

I have the Ryobi inflator and have not been happy with it. It’s fine for bike tires but not really needful unless you are doing a family ride and have ten tires to hit. When you hook it up to a truck or trailer tire it’s a bust. The pump and hose heat up fast and it can’t get much past 35 psi very easily and 70 is a distant dream. The head is the same you get on any cheap nasty pump.
