Flat, 30 km from home
A soft or flat tyre mid-ride with no fast way back up to pressure. That's the ride over — or a long walk.
PocketPump · A3 Max Mini Electric Bike Pump
Never guess your tyre pressure again.
A rechargeable 150 PSI pump the size of an earphone case, with a live digital gauge accurate to ±1.5 PSI and an auto-stop that hits your number exactly. No cartridges to run out of. No hundreds of strokes. No hoping it's "about right".

The reality of a flat
Every rider has a story that ends in a long walk.
One-shot CO2
Cartridges are single-use. Miss the seat, use two on one tyre, and you're stranded with an empty jersey pocket.
Guessing with a hand pump
Hundreds of strokes, no gauge, and a tyre you 'think' is about right. Wrong pressure ruins grip and rolling speed.
Sensors that cut off early
Tubeless riders report cheap pumps misreading a sealant resistance spike as 'done' — leaving the tyre under-filled.
The answer
Pressure control you can actually trust.
Straight answers to every objection riders raise about pumps in this category — including the ones most brands leave off the page.
Stranded by a flat with no way to reinflate
A rechargeable 1800mAh pump that lives in a jersey pocket or seat bag and refills on any Type-C cable. No cartridges to run out of.
Sensors that cut off early on tubeless setups
A live LCD gauge accurate to ±1.5 PSI means you see the actual number the whole time. If a fill stops short, you can see it and restart to target instead of riding on a soft tyre.
Poor seal at high pressure on direct attachment
We say it straight: use the included extension hose above ~60 PSI. It gives a solid, square seal and keeps load off the valve stem.
Saddle-bag space is tight
At ~128 g and roughly 69 × 42 × 28 mm this isn't the smallest pump made — it's the smallest one we'd trust to hit 150 PSI. Compact enough for a jersey pocket or seat bag.
Can something this small really hit high pressure?
Rated to 150 PSI / 10 Bar with 25 L/min airflow, an aluminum heat-shedding body and thermal cut-off so it isn't running past its limits.
Wet-weather worry
It is not water-resistant. Store it in the supplied silicone cover inside a seat bag or pocket, dry it off after a wet ride, and it'll keep working.
Built in
Specs that do the work for you.
150 PSI, on demand
10 Bar of real pressure from a unit the size of an earphone case. Set anything from 0 to 150 PSI.
Digital LCD gauge
Live pressure readout accurate to ±1.5 PSI. Stop guessing by thumb-feel or a rattling analogue dial.
Auto-stop at target
Dial in your number, hit start, walk away. The pump shuts itself off the moment it hits target.
25 L/min airflow
A measured, verified flow rate — not a marketing number. Steady fill on road, gravel and MTB volumes.
Every valve, no swapping
Auto-detecting Schrader and Presta, plus a needle adapter for balls and inflatables. Adapters included.
Overheat protection
Thermal cut-off and auto-standby protect the motor and battery on long or repeated fills.
Type-C fast charge
1800mAh cell, full charge in about 25 minutes off the same cable as your lights and computer.
Anodized aluminum body
CNC-feel alloy shell at ~128 g, with a silicone sleeve so it doesn't rattle in a seat bag.
How it works
Three steps, roadside.
- 01
Attach
Thread on the extension hose (recommended above ~60 PSI) and lock it to your Presta or Schrader valve. The pump auto-detects the valve type.
- 02
Set your PSI
Use the + / – keys to dial in your target on the LCD — anywhere from 0 to 150 PSI.
- 03
Press start
Watch pressure climb live on the display. It stops itself at your target, then drops to standby.

Blooming fabulous, works better than advertised.
Works well. Small and compact. Easy to use.
Game changer. Lovely product. Arrived in less than a week. Thank you.
Great item, thank you. It weighs about 150g (from memory) which is more than a mini pump but much quicker to inflate tyres.
The item matches the description and works very well.

Answered straight.
It's rated to 150 PSI / 10 Bar with an adjustable 0–150 PSI target. For high-pressure fills use the included extension hose — direct valve attachment is less secure at the top of the range.
