Product Reviews

Teslong tire inflator digital display showing 36.0 PSI.
Time saver

The first thing I tested with this inflator is the range of pressures it will support. I've had problems in the past where some inexpensive inflators or the inflators attached to jump packs would not go as low as 6.5 psi. This one does and it goes all the way up to 150 which is amazing. The 26 inch wheels use a lot of air volume.But I hate waiting, and since I often have to reinflate these I'm really glad that I've got this tool that can do it so quickly.

Good Pump, Includes Adapters, and A Little Vacuum Pump

Almost like an all-in-one air pump with a little vacuum sidekick. This kit does include most, if not all, the necessary adapters for all my inflatables, floats, and balls. This little vacuum pump is not that big or as powerful as my other inflatable pump, but it will get the job done, and it fits nicely into that little storage space at the front of the main air compressor.

Good power, battery powered with accessories in case

The unit comes with a battery. A compressor has a bunch of different tips on the underside for pumping up balls or air mattresses. This is a nice addition for an inflator to be included like this. This is a good value and I think a nice design and package so you can keep it in your vehicle all the time.

A must have portable tire inflator and so much more.

I have a few items from Teslong and they all work great and are well built. This dual cylinder portable tire inflator is no different.The device has this really neat feature, you pop open this front door of the unit and out comes a small high output pump. It uses all the orange adapters for blowing up inflatables. Don't let is size fool you its pretty powerful.

Frequently Asked Questions

Will it inflate my SUV or truck tires?

Yes. It handles tires up to 315/70R17 — that covers all sedans, compact and mid-size SUVs, EVs, and light-duty trucks like the F-150 and Silverado 1500. A standard SUV tire (225/65R17) tops up (30→35 PSI) in about 60 seconds.

Can I use the battery to charge my phone, tablet, or laptop?

Yes. The 45W USB-C port works both ways — charge the inflator, or flip it around and use the battery as a power bank for your phone, tablet, or laptop. Handy when you're stranded with a dead phone or off-grid at a campsite.

What can it inflate besides tires?

A lot. Beyond cars, motorcycles, bikes, and balls, there's a separate high-volume pump (230 L/min) that inflates tents, air beds, kayaks, and pool floats in seconds — and runs in reverse to vacuum storage bags flat. Five preset modes and included nozzle adapters cover just about everything.

Is the battery safe and certified?

Yes. The battery is certified to UL 2056 and UL 2595, the unit is FCC compliant, and it's UN38.3 tested for safe transport. Built-in motor over-temperature and multi-layer battery protection guard every job, and it's drop-tested and rated to work from 14°F to 122°F (−10°C to 50°C).
