ADVANCED TRUEGAUGE SCREEN: This air pump includes updated sensor technology, capable of collecting pressure data from tire inflators at a frequency of 200 times per second. Its valid data rate is higher than 80%, which is 60% better than the market average. Wherever you go, accurate readings help you drive safely.
2X FASTER INFLATION & COMPACT: Weighing less than 1 pound, this portable bike tire pump is easy to carry and store in any limited space, such as cars, bike racks, or backpacks. The compressor’s 150 PSI maximum pressure, coupled with its 17L/min airflow delivers 2X faster inflation. It can refill a 195/65R15 tire from 30 to 36 PSI in 1.5 minutes.
LONG RUNTIME & AUTO-OFF: After fully charging, the built-in 4000mAh large-capacity battery allows the car tire pump to refill up to 8 tires (195/65R15) from 30-36PSI. The preset function and auto-off function deliver a hands-free inflation experience. With just one press, the cordless bike tire pump will easily inflate car tires, motorcycle tires, bicycle tires, ebike tires, balls, and more. (Note: Incompatible with heavy-duty tires, like those on offroad vehicles, RVs, trucks, and trailers.)
EASY TO USE: You can choose 4+N smart modes (car, motorcycle, bicycle, ball, and custom) based on your various inflation needs. You can also easily choose between 4 pressure units as needed (PSI, Bar, kPa, kg/cm²). The custom mode allows you to freely preset the desired pressure value (3-150PSI) based on the inflatables you want to inflate like ebike.
VERSATILE EMERGENCY TOOL: The bike pump can be used as more than an air pump, it is also a multifunctional emergency tool. The flashlight on the top has 3 modes (flashlight, SOS, and strobe) to illuminate the night for easy operation. The air compressor is equipped with USB-C and USB input/output ports, providing backup power for your phones and other electronic devices. Note: Please fully charge the Tire Inflator (using a 5V 1A battery charger) before using.

Great little product so far…
I just opened this product this morning and used it immediately. The air pump was fully charged out of the box (PLUS) and I used it to inflate my car tire from 30, to 40 psi. This took about 5-10 min. (meh). I then took it to work and inflated a few different sports balls. Inflating the sports equipment was much more quick & efficient (PLUS). After all this the pump still reads that it is fully charged (Awesome!). AND I love that it has a large range of possible pressure settings (3-350psi) as well as preset pressure settings and it automatically shuts off when the desired psi is reached (PLUS).Cons: I just have a few small issues with this product, but none that are deal breakers. 1) It is a bit louder than I would prefer (sounds just like a regular size air compressor). 2) It took quite a while to inflate my car tire just 10 psi. And 3) you have to screw the hose to the tire valve stem (understandable, but I wish it had a clamping attachment), when detaching the hose I lost a little bit of pressure. I would recommend maybe going up 1 psi to counter this issue. Overall it was very easy to use without reading the instructions, and it will definitely come in handy when I need small inflation jobs completed. Time will tell how durable this pump is; I plan to leave it in my trunk so hopefully that will not cause it to malfunction. If the above does not bother you I would definitely recommend this purchase.

AstroAI L7 for Everyday Use
Iâve been using the AstroAI L7, and Iâm thoroughly impressed. Right out of the box, itâs clear this is a thoughtfully designed product. Itâs compact and lightweightâeasy to toss in a backpack, bike bag, or car trunkâbut donât let the size fool you. This thing is powerful.Inflating tires is quick and effortless. I used it on both my car and mountain bike, and it handled both with no problem. The digital display is bright and easy to read, showing both current and target PSI. I especially appreciate the dual values displayâit saves me from second-guessing how much more air I need.The automatic shut-off feature is a game changer. Set your desired pressure, press start, and it shuts off exactly when it hits that number. No more over-inflating or constantly checking the gauge.

Great addition to your trunk! Works perfect.
I recently purchased the AstroAI L7 Tire Inflator Portable Air Compressor, and itâs been a fantastic addition to my car emergency kit! This compact, cordless inflator is a game-changer for quick tire maintenance and more.Weighing under a pound, the AstroAI L7 is incredibly portable, fitting easily in my glovebox or backpack. Despite its small size, it delivers impressive performance with a 150 PSI maximum pressure and 17L/min airflow, inflating a 195/65R15 tire from 30 to 36 PSI in about 1.5 minutesâtwice as fast as many competitors. Iâve used it on my car tires, bike tires, and even an inflatable mattress, and the five inflation modes make it versatile for various needs. The digital pressure gauge is spot-on, as I confirmed with a separate tire gauge, ensuring accurate inflation every time.The battery life is solid, handling multiple inflations on a single charge, and it comes fully charged out of the box, which is a nice touch. The USB-C port is a bonus, doubling as a power bank for my phone in a pinch. I also appreciate the built-in flashlight for nighttime emergencies and the screw-on connector, though it takes a moment to get used to compared to quick-connect valves.Noise level is high but it works. Can get a Can get a little hot, but not too bad. Overall, the AstroAI L7 is reliable, user-friendly, and an excellent value for the price. Whether youâre a driver, cyclist, or camper, this inflator is a must-have for staying prepared on the go. Highly recommend

Good for everything it does, but its real strength is its portability.
Works really well. I’ve used it to inflate my car tires (I drive a Hyundai Sonata 2013), as a light, and as a battery pack. It’s most useful for its light and battery pack functions (a good item to have in an emergency in any case), but it did manage to inflate my car’s tires cleanly as well.Easy to use for inflating objects, but you’ve got to be careful if you’re using this on car or truck tires – The hose connection needs to be fully screwed into the tire’s threads or the backpressure will outpace the pump’s ability to fill.Went from 20PSI to my target of 35PSI in about 2 minutes 30 seconds, and the autoshutoff signalled completion.

Easy, Dependable, works great!
Excellent! I take on long bike rides and don’t have to worry if I get a flat. The pump goes to 150 psi, I keep my bike tires around 95. It inflates fast and effortlessly. Easy to program.I’ve already used it when I got flats. Just changed the tube and Inflated. Can use on your car tire too.When I called Astro AI customer service, they were very helpful and went above and beyond to help me out!You can use it to charge devices too I understand.Highly recommended!

Works perfectly. 35PSI to 37 in half a minute. I haven’t used it for a long time, so I can’t say about it’s longevity, but the product feels good quality. The motor is noisy, but it is well worth the price and the job it does.

What a wonderful little device. I had a car for years in the garage and all the tyres were fully flat. I used this to pump up all the tyres to full from zero. I had to put it back on the charger after each tyre but it was recharged in and hour or two. All the fittings and attachments are high quality and connected well to the tyre valves. It would easily do bike tyre and I will carry this now in the car for emergencies.
