Portronics Vayu 3.0 tyre Inflator with 150 PSI Pressure, 4000 mAh Battery, Digital Display, Pressure Detection, Air Pump Compressor for Cars, Bikes, Bicycles & Balls(Black)

Very useful item and just loved it... Have 3 bikes and 1 car.... Each and every time just for filling air we can't take vehicles for petrol pumps to refill air... By using this product I was able to fill all the vehicles within few minutes.... Just make sure to charge the device minimum of 2-3 hours before using it for better usage and to sustain life of the battery.... Not sure how many days we can keep on charging and reusing this. Size is very compact... Yes it makes some sound... Display is very nicely built we can set out desired air pressure also it shuts off as soon as it reaches the saved one's. If u use long without any gaps yes heat can be sensed... Handy product for sure, can carry it anywhere and we can charge and discharge with this product.....

Working properly but there is an heating issue while you start this overall this is good according to the price 🙏🏻

⭐⭐⭐⭐⭐ Excellent Product – Must Have for Every Car Owner! I purchased the Portronics Vayu 3.0 Tyre Inflator and I am extremely satisfied with the performance. It is compact, powerful, and very easy to use. The 150 PSI pressure capacity works perfectly for my car tyres, and the digital display makes it very convenient to set the desired pressure. The 4000 mAh battery backup is impressive and inflates tyres quickly without any hassle. Build quality is solid and the product feels premium. It’s portable and very useful during emergencies or long drives. Highly recommended for everyone. Totally worth the price!

The product is good and works fine. Battery backup is sufficient for a top-up to all 4 tyres. Overall good product

Writing this review after using it for many months. It worked very well for first few months. I was able to inflate all 4 car tyres, 2 tyres of Activa and Ather in single charge. After few months - it's battery drains out very fast.. Now I can hardly inflate 2 tyres and battery is dead. Also, i used it once in a week or 2 week - so it's not like very heavy usage. Updated after 1+ year: Used this hardly for 50 times and battery is totally dead... Now with full charge as well, It will hardly start.. Cannot fill even single tyre now.. More Update : Since I have to anyway throw away this product - I took liberty to dissect it. Here are few more observations 1. Build is quite robust as seen from photo I posted. In case anyone want a clue on how to open it - there is sticker on below side which is smartly integrated in design. Once you peel off the sticker whole assembly can be pulled from front. 2. Claim that battery is 4000mAh is again false. There are 2 Cell 2000 mAh battery unit of 7.4 - 8.4 V (18650 type cell). In case manufacturer is reading my message - here is my feedback on improving your product 1. Keep up the robust design - I like internal mechanics, motor you have used and airtight assembly you have built unlike some other cheaper brands 2. You just need to improve on 2 things - Get robust BMS (Battery Management IC) and bit good quality rechargeable cell. Currently, I think most unit fails as this product is getting charged using fast charger and I guess there is no cut off in existing circuit once battery is charged. This damages battery very quickly. This might add hardly 50-100 rupees to your cost but your product will become much more sustainable in the market.

Using this for almost 1 year. Hadn't thought much of it until I got a slow puncture on a highway stretch with no petrol bunk around. Pulled this out, pumped the tyre, rode to the nearest mechanic. That was enough for me. The pump is a bit slow but it works fine for bike tyres. Powerbank has saved my phone on a couple of long rides when I forgot to charge before leaving. The flashlight is handy for quick checks at night — nothing fancy, but bright enough. Three things I actually use, in one thing that fits in my bag. Solid buy for anyone who rides regularly.

good one but battery backup reduced
