This deal is back and now cheaper than before for those who missed out. These are essentially small battery powered air compressors designed for pumping up smaller tyres like those found on bike, e-scooters and mobility scooters. They can be used to top up car tyres, but it will take longer due to the flow rate/battery.
Since this is an air compressor it's not suitable for filling up air mattresses, paddleboards, beach balls etc unless you use a special adapter (i.e. this), however it won't be perfect.
The main difference between the 1S and 2 is that version 2 inflates 25% faster (15L/pm flow rate in 1S), has multiple adapters including a quick connect adapter, an electric scooter preset mode and increased light brightness.
Like the 1S it goes up to 150 PSI, can be set to PSI/BAR, has USB-C charging and an inbuilt light.
AU$ based on current Mastercard rate and GST inclusive.
I have the 1s and use it for topping up my motorcycle tyres, works brilliant. However your link is not working my friend
