Tiny Bike Tire Pump, 100PSI Electric Bicycle Pump, Protable Cycling Pump with Schrader and Presta valves, Integrated Safety Light, 80 Seconds Quick Inflation for Road Bike, Mountain Bike

I'm a minimalist cyclist, and my small saddlebag is restricted to the bare minimum. I typically carry one spare tube and two CO2 inflators just in case. But of course there's the risk of having another flat or something going wrong with an inflator. This little pump fixes all that. Easily fits in a jersey pocket or saddlebag, and will manage probably half a dozen inflation cycles. It is fairly loud, but that's a small price to pay for such a handy tool.

Excellent

UPDATE: I finally took it apart to troubleshoot. There's a small 7.4V battery pack, which is made up of two 3.7V 802030 batteries and a protection control module (to regulate charging). One of the two cells is just fine, but the other one got hot and pressurized quickly. (Kids, don't try this at home.) One of the two cells in the battery pack failed after 2 uses. Your mileage may vary, but enough other people are complaining of the exact same problem. In fairness, I had the exact same thing happen to a battery-powered automotive tire pump too. I'm 0 for 2, and done buying rechargeable battery-powered tire pumps. They're clearly not suited for the purpose. --- I tested this when I received it, and it turned on/pumped. I used it about 2 months later to top up my tires, and it seemed to work. But the very next morning I went to use it again and it wouldn't even turn on. I plugged it in and left it for ~4 hours. No light ever came on while plugged in (same USB-C charger I use for my phone every day, which worked before and continues to work after attempting to charge the pump). I've seen this flaw with other handheld pumps - they seem to drain to the point where the charging unit considers the battery damaged/unchargeable, so it turns into an expensive paperweight (at least as paperweights go). Several others are complaining of the exact same thing. In summary, I got one legit use out of this pump, and now it's garbage.

I let the air out of my mountain bike, the mini pump filled both tires 29 pounds pretty fast, with battery to spare. Good to get to truck, better than pushing. Charges pretty fast.Very small, lightweight, Read all the reports pretty good. A little noisy and gets a little hot not bad. Now I'll let the charged mini sit for a week and see how the battery does.

Flextail has amazing customer service !

Maybe if I was doing long distance bike packing or something where I would want more convenience doing a repair, I might carry this. However for my day to day workout and commuting rides this seems excessive. It's relatively expensive, large and heavy. I'd rather carry a small C02 canister or even a mini pump, both are lighter (and less expensive). Also if it runs out of juice or the battery dies, you're out of luck. I'm sure for the people that like this type of thing its great- so I'm giving it a 3, but for me it's a 2.

I bought this for my husband for his birthday. Now all his buddies want one. He has been the "go to guy" when somebody has a flat tire on a group ride.

It’s small and easy to carry. Would be nice if it had a gauge. No idea how much air is in the tire. Have to use old school feel the tire to know it’s inflated. Directions are absolutely terrible.

Es una bomba para dos pinchazos. Práctica, si eres el que poncha más de dos veces, no es para ti.

Compact and easy to use.

Works as it should but much louder than I thought it would be!

Funciona de maravilla, super recomendable yo la uso para bici de ruta.

Easy to carry for emergencies but no pressure gauge so not ideal for routine use. Works well on presta valve for bikes.
