Firstly, re this device having no charge/charging indicator? YES, IT DOES! As per page 17 of the manual (I know, no one reads manuals - me included normally. However? At times, e.g. when tidying up/bored, something isn't working out of the box? Yeah I might skim one...) -

While charging? The white indicator light blinks. When full? It stays on. Sorted!

Though in saying that? To me, this is the kind of thing you'd charge after each use and/or charge/check prior to taking it away from any sources of electricity, e.g. if (as per me) relying on it for emergency use when outdoors on two wheels. Because despite carrying a power bank as well, juice is important and you want as much as possible, right?
In my humble opinion? This thing is GENIUS - whoever invented it, is, I hope, revelling in the fruits of their mind, because I honestly don't know how I could ever go without it now. Relying on a manual pump is cumbersome and annoying - inflating a tyre at night, after navigating the repair/replacement of tube, in the dark - even with the right tools - is time consuming and irritating (the latter moreso because it's usually some numbn*ts' stray nail/bolt/piece of sharp [email protected]/swept aside motor accident debris - all wonderfully left in the cycle lanes of life etc for tyres to decide they want to become friends with, YAY! Not).
No cons re this device - I don't care if it's anything than someone else expected (bigger/heavier/whateverer - realistically? It's none of those, because it has FUNCTIONS - e.g. a perfectly positioned light! YAY - voila! When it's dark, you can see what you're doing with the inflation hose (which screws on to standard cycle wheels, no attachment required* - brilliant, because as noted by another reviewer? ZERO air loss on connection/disconnection).
*Note: As well as USB cable and soft storage pouch? Included in the box are two additional attachments - Presta Valve and Needle Valve. And? There's a small - secure - internal pocket in the soft bag to put them in. See? ALL ROUND GENIUS.
It stops deflating automatically on reaching pre-entered PSI (or other selected unit of measure). And? It retains that setting for the next use. GENIUS.
They really did think of everything re this device. Can't fault it. Won't fault it. A zillion stars out of five. Thank you Xiaomi and PBTech.
PBT stock some awesome products you just don't find elsewhere; delivery is always prompt; collection from alternate dedicated locations is a brilliant idea; sales have awesome deals - happy repeat customer.

Purchased this pump mainly to keep the tyres on my Xiaomi scooter topped up. With other pumps, unscrewing the pump from the valve caused air to leak out which meant losing about 5-6psi. With this, unscrewing caused very little air to leak out meaning you didn't have to overinflate. Purchased this pump mainly to keep the tyres on my Xiaomi scooter topped up.

Topped up the tyres on both cars today. Just ensure that you fully charge before using.
Acceptably quiet, well built, very portable and good value at the special price.
Well done Xiaomi, another winner.

Worked well with my scooter and my bike as a good pump for small tires. Runs on a battery and can pump air in minutes. Works well and can get you going again in case you have a puncture or any other kind of mishap with your bike and/or scooter. This is a must for riding around on and should be packed in your backpack or bag on your bike in case of emergency. Worked well with my scooter and my bike as a good pump for small tires.

Works well with a number of valves and situations. Works well with a number of valves and situations.

took to a basketball tourament takes the guesswork out of ball, inflates to the desired psi and stops (no over inflation)i think after using i probably sold few of these units).
hand pumping is always guesswork to how hard you think it should be... stop the arguments by choosing level, push go.
ready to go straight out of the box. power plug or usb charging. small enough (about the size of a portable HD) leave in the car for piece off mind flat tyre issues. all round great product. took to a basketball tourament takes the guesswork out of ball, inflates to the desired psi and stops (no over inflation)i think after using i probably sold few of these units).

I bought two of these and I’m so glad I did! One goes with my bike and one in the car. We have used them a few times already and it is a great product AND good value for money! Plus - PBtech are VERY quick to post! I am a very happy purchaser ! Thank you! I bought two of these and I’m so glad I did! One goes with my bike and one in the car.

Portable and compact,not bigger than a samsung note, it inflates my motorcycle tires with ease. Great to have with you when offroading. Portable and compact,not bigger than a samsung note, it inflates my motorcycle tires with ease. Great to have with you when offroading.

Brilliant. 12 mins inflated the flat tyre to 30psi. 215/45 Brilliant. 12 mins inflated the flat tyre to 30psi. 215/45

I bought this for topping up our car tires at home when they're cold. I'm not sure if I'd ever use it to inflate a car tire from flat, it seems too puny for that (unless perhaps the tire wasn't under load, such as when the wheel has been jacked up). I think the manual states it's accurate to .1 bar, mine gives a reading about .1 higher than my old tire gauge, so +/- 0.1 would seem about true. I can't give it full stars until it's proven itself over a few years of occasional use. I bought this for topping up our car tires at home when they're cold.

Best on the market. Used on car repair and on scooter. Nothing but positive Best on the market. Used on car repair and on scooter. Nothing but positive

Outstanding item for its price, works on both valve styles and very accurate and portable. Thoroughly recommended Outstanding item for its price, works on both valve styles and very accurate and portable. Thoroughly recommended
