Portable Electric Digital Tire Inflator Air Compressor, Smart Car Tire Pump Bicycle Air Pump, 2500mAh 120PSI Pressure Gauge, for Car Bike Motorcycle, Various Balls, Multiuse Flashlight and Powerbank

Overall this could be a pretty useful tool for some users and it works, in some cases. As a cyclist who rides 5+ days a week, I bought for two reasons... first, primarily so my indoor trainer workouts always have the exact same tire pressure for accuracy from ride to ride to measure power accurately so forth. Second, I bought for convenience on trips to avoid hauling my big manual floor pump around in the car and taking up space. It really is a great idea for a tool, all the settings work fine, and I like the ability to customize several settings. It works fine on just schrader valves (I haven't tried with beach and sports balls, etc.)There don't seem to be any issues with getting the right pressure and the time depends on how much inflation is needed, but its pretty quick - maybe about the same as the floor pump (takes a couple minutes from full flat), no more than 30 seconds to top off the last 10+ psi. It works fine for full inflation or topping off the tires before an outdoor ride or group ride, although its a little too big and definitely way too heavy to be practical for carrying in my saddle bag for emergency use on the outdoor rides.The hidden inflation tube is convenient. The pump holds a decent charge, but seems to need to be at full charge or it won't read PSI and work properly. Sometimes even when showing still full charge or a mostly full charge after having used numerous times, it doesn't always read the PSI right or inflate. Sometimes it will just do a quick 1 psi bump and show fully inflated even though it isn't. When a lower or middle charge, it will just pump for a second and shut off.When initially connecting the pump, the PSI doesn't always read correctly (or sometimes at all). Most of the time I have to start inflating before it will read any starting PSI. Sometimes it will show what PSI it is, but then just start rapidly dropping numbers without losing any air pressure. Also, the little pressure relief button doesn't work very well. Sometimes it does no relief, sometimes just a quick little mini-burst releasing maybe <1 psi and none further, sometimes I can do several consecutive mini relief bursts, but always very minor. If really trying to release a lot of pressure from the tube, it won't work, I'll just have to take it all off and manually release the air from the tire valve.The biggest issues are the pump tube's valve adapter end - as well as the presta adapter particularly. My advice, don't use at all on presta valves or be very very careful. If you use the presta adapter that comes with it, it often doesn't work, or the gasket on the adapter pulls out when removing from the stem, or it pulls the entire presta valve core out. I've wasted over half a dozen, perfectly good brand new presta tubes where the pump adapter pulled the presta valve core out, or where it bent the valve stem, or pulled the stem itself out of the core, or 'jammed' the stem up into the core making it so it won't read pressure and inflate properly. I've even resorted to using with a presta-to-schrader valve adapter instead of the adapter that comes with it so I can screw that on the bike tire first, then screw their schrader end on to it, which has to be done very carefully not to get the threads crossed even slightly. Crossing threads is easy to do when using the schrader end that comes on the pump tube, and then also just threading the adapter to bike tube. Or the presta-schrader adapter and schrader end on the pump tube get locked up together and when trying to unscrew them from the bike tube since you need one hand just to hold the pump (since the pump tube is short) and one to unscrew the tube adapter, but they instead screw off together and you lose alot of pressure or bend the presta core stem or pull out the presta core. I've even bought a traditional spare 'clamp-style' pump presta adapter with a long tube to try some sort of 'hack' to use with their pump tube valve adapter or just maybe cutoff the end and combine the two but haven't yet.In the end, its a great idea for a convenient tool, it mostly works, has some quirks in some cases, but definitely requires extreme care to use with presta valves and even then is going to cause some problems and losses. If everything worked consistently well and it didn't destroy my presta tubes, I'd easily rate this a 5-star tool, it could be that useful.

Purchased 10 months ago. Arrived with a debt in plastic case but thought I'd try it anyway. Worked great the 4-5 times I used it, but after sitting 2 months unused, ai topped off the charge, but it instantly goes dead when pump starts. Sent inquiries on warranty two different ways to Reesibi in the last week, but no response. I've seen other companies ignoring warranty service until you make bad reviews, so we'll see how they do on this one.Update: 2 days after my first review I was contacted by Reesibi to submit info regarding problem with product. 2 days after I was told they'd send a replacement. 2 days later replacement arrived. Topping off the charge in the new one now.After being informed I didn't have to send the original back, I took it apart (had to destroy the plastic casing to open it) and found the (2) 3.7v Lipo batteries were attached to their own tiny protection circuit board. i separated the batteries and put them in a Nitecore um4 charger, which indicated they held .7v. This most likely meant the batteries git so drained in the 2 months since I used the pump, that the protection circuit wouldn't let them be charged again. I used my Nitecore charger's reconditioning mode, and the batteries are fine.Moral of the story: Don't let this pump sit unused for more than a few weeks before topping off the charge, or if the voltage drops too low, it will refuse to charge.. I think since it has the protection circuit, you should be able to store it connected to a charger also.

Works great for small things. Car tires it does work just takes way to long. I bought this for my Harley and keep it in my saddle bags. I never go on a ride without it.

This device is amazing pump all my tires within 10 minutesI have high performance low profile sports car and this device works great

UPDATE: 12/6/2021 -The seller reached out to me regarding the defective pump and offered to send out a replacement without any 3rd degree. Very pleasant to work with and despite the supply chain issues delaying the shipping, everything worked out fine at the end. The new pump works as expected. I will update after a couple of months of use to report on the reliability. Raising my star rating from1 to 3 for the pump, adding one star for the superb customer service.The write up for this pump looked good. The english wasnt the usual bad "chinglish" and the details provided seemed to hit everything I was looking for in a portable pump. The price was not the cheapest on Amazon but also not the most expensive. Usually a good spot to be.Had this portable inflator a little less than 2 months. Worked great in the beginning. The pressure gauge was accurate and the battery held up long enough to top off 4 tires with 3-5psi once a week for 2-3 weeks without having to recharge.BUT.... then the problems started.First the pump will occasionally throw an E02 error. Powering off and powering back on usually reset it to allow me to continue. That continued for a couple weeks.Then the pressure gauge started to act up. 30psi was displaying as 40 psi. No biggie, I thought. I'll just over inflate and then use a standalone pressure gauge to trim the psi.Last weekend, the pump just gave up the ghost. The pump throws an E02 EVERY FRIGGIN TIME! No amount of resetting will clear the error.So now, a month past my return period, this POS is just that, a POS.

A little loud but it works well. Adapter for presta valves not the best (difficult to fill bicycle tires).

３年程で現行のポンプの充電量が低下した為、代替購入。クルマとバイクに使用。一月で大体0.1気圧程低下するので毎月補填しています。この製品の表示精度は±0.1程度で過剰充填にはならない様なので安心しています。ガソリンスタンドで確認するのが一番でしょうが、ひと月以上間隔が空くので、2回に1回はポンプを使用する感じです。もっと値段が高くて精度の高い物がいいのでしょうが、今回の様に上手く当たればこれで充分だと思います。

El funcionamiento es muy intuitivo y tiene diferentes opciones, buena calidad y tiene diferentes boquillas.

本体を振るとカラカラと中でネジみたいなものが転がる音がする。大丈夫か？追記すぐショップから新品を再送していただきました。万一ハズレ引いても安心して購入できると思います。
