There are plenty of things in life that make it easier, and the Xiaomi Mijia Air Pump 1S is one of those. I'll be honest, pumping air into my bicycle's tyres is easy to do, but there's quite a bit of work to get it to the right air pressure. It's powerful enough for filling up a car tyre as well despite its small size.

I'm honestly quite impressed with the design of the Air Pump 1S. There's no power button — instead, the hose acts as a switch. It's turned off when plugged in, and when you pull out the nozzle, it turns on. I honestly quite like how simple and clever this is. The nozzle also supports the usual Presta and Needle valves, and comes with adapters. There's also a bag included.

The pump supports car, bikes, motorcycles, and can switch between Bar and PSI units. You can also inflate balls with the pump. Sadly, there's no battery indicator to tell you just how much juice it has left. Instead, you have to guess. However, Xiaomi does provide an estimate. For car tyres, you can fully inflate up to two times, or top up around 8 tyres. It can go up to 150 PSI, and will remember your last used setting.

So far I've inflated four bicycle tyres, and then checked it with a manual pump to see how much pressure are in the tyres. It's been pretty accurate, and the pump didn't feel too hot when done. There's also a built-in light that's surprisingly bright and has a flashing mode for emergencies. The pump is also portable enough you can bring it along for a ride or just leave it in the car for emergencies.
For S$46 (or less), the Xiaomi Mijia Air Pump 1S is a worthy buy for your gadget arsenal. You'll get plenty of use out of it, whether you're a cyclist or just want to fill up your floats for the swimming pool. Get it from Lazada or Shopee.
