Tiny Bike Tire Pump with Gauge, CYCLAMI Max 150/120/100 PSI Electric Bicycle Air Pump, Auto Stop, Presta and Schrader Valve Aluminium for All Bike, Type-C Rechargeable Battery

It broke after first use. it gave a few funny sounds and stuck forever. Re-charging didnt help.I live in Israel so sending the product back would cost me more than the whole product.TOTALLY DISAPPOINTED!!

I've seen name brands go for up to $100. I was skeptical that this could be as good. I inflated my fixed gear tires, both to 100psi in a few minutes! Crazy! It did get very warm near the nozzle, but there is a nice warning letting you know. This is great to have on a ride for a backup bike pump! It's louder than I thought it would be for the size, it kind of startled me when I turned it on, hahaha. Not anything to prevent me from recommending it though!

I got this pump to throw in my cycling bag to replace my existing emergency CO2 inflation system for emergency tire changes for both my mountain bike and 2 electric scooters. It is compact and convenient and the pump is remarkably strong for being so small. This pump will easily fit in my small accessory bag and with full charge it can easily inflate a regular sized bike tire in an emergency situation without any problem. As a test I charged it fully and then released all the air from my 27.5 inch mountain bike tire. Once it was completely flat I was started inflating with the pump and had it up to 40 PSI in about 2.5 minutes and the pump was still going strong even though it was quite warm. The product description advertises max runtime of 250 seconds which means you might be able to squeeze out enough air for two regular tires or one large tire. In addition to this it can also be used to fill balls needing a needle filling accessory. I really like that this pump supports both Schrader and Presta valves but I do wish it had a locking collar so you wouldn't have to keep it held with your hand against the valve the entire time while filling The instructions that came with the manual and pretty poor but it's a basic device that really doesn't require much explanation. I also wish it came with a built in way to check the pressure but that might be asking too much from such a tiny device that is smaller than a pack of cigarettes. It may not be the fastest or have the longest battery life but it is super compact and easy to carry anywhere and is adequate for most emergency tire fills. This beats using a manual pump any day when doing an emergency repair while out on the road or woods.
