150PSI Bike Pump, Bicycle Pump with Digital Pressure Gauge, Electric Bike Air Pump with Presta and Schrader Valve for Bicycle, Motorcycle and Ball

UPDATE: I got enthusiastic and went down to deflate the wife’s tire. I filled the charge on the pump and topped off her back tire, ~43psi up to 60psi. After that I set about inflating the flat front tire. It made it up to 52psi before it ran out of go, so I’d say it’s fine to refill 1 and only 1 tire from flat if your out on the road. Lost a star for that. Granted, these are mtn bike tires, so they’re a lot higher volume than a road tire, but I suspect the weight of this pump precludes it from most of their kits anyway.So, it’s not the lightest thing in the world, and using it is a little weird to get used to, or at least it was for me. But it’s still smaller, not much heavier, and WAY more convenient than any other pump I’ve ever had.So details, here’s how I’ve used it so far: Aired up the wife’s and my tires from just general deflation, so around 47psi, up to our usual full, about 60psi. Did fine, never shut off for heat or anything. Well, I just left the thing on the bicycle rack in the garage for a few weeks (1 to let my tires go down a bit, and then the other two because I’ve been lazy), and I used it today to air my tires back up, from about 47psi, this time I cut it off at 57.5psi because I couldn’t remember what the limit was and was too lazy to check the tires again (it’s cool, they say 40-65). Anyway, no shutoffs again, but I could tell it was getting tired on the second tire. Battery showed very low after it finished, but it did both tires without any real trouble. I brought it back up to recharge now. But anyway, I’m reviewing this based on getting 6 tires worth of basic inflation. I haven’t tried on a completely empty tire, but I suspect you’re probably looking at 2, max. Definitely won’t replace my regular pump, and probably won’t replace my travel pump until I’ve refilled from flat a time or two, but this guy is definitely living in the bicycle bag for anytime I realize I need to top my tires off and so I can try it out when I get a full flat.
