Electric Bike Pump vs CO2 Cartridges: Which Should You Carry?
Speed, weight, cost per fill and exact pressure: an electric mini pump and CO2 cartridges compared.
Written by INFLATA. We make the Pro S electric mini pump, so we are not neutral. This comparison uses retail prices and an independent test, and tells you when CO2 is the better choice.
For years, CO2 cartridges were the fastest way to get a flat tyre back up at the roadside. Electric mini pumps now offer another option: no cartridges, a digital gauge and an automatic stop at the pressure you set. Which one belongs in your saddlebag depends on how you ride.
Quick answer
- Choose CO2 if you race, want the lightest possible kit and only need to fill one tyre in a hurry.
- Choose an electric pump if you want exact pressure, more than one fill, top-ups before a ride and no cartridges to buy or throw away.
Electric pump vs CO2: side by side
| Electric mini pump (INFLATA Pro S) | CO2 cartridges (16 g) | |
|---|---|---|
| Speed | Under a minute per road tyre | A few seconds |
| Fills per charge or cartridge | Up to 8 tyres per charge | 1 tyre per cartridge |
| Exact pressure | Yes: digital gauge, stops automatically at the pressure you set | No: you get what is in the cartridge, then check with a gauge |
| Weight | About 125 g | Lighter: a cartridge plus inflator head weighs less |
| Cost to start | €99.95 | Around €15 to €26 for an inflator head |
| Running cost | A USB-C recharge (about 30 minutes) | Around €1.60 to €2.30 per threaded 16 g cartridge |
| Waste | None | An empty steel cartridge every time |
| Home and pre-ride top-ups | Yes | Not practical |

Where CO2 wins
- Speed. Nothing beats a cartridge for getting a tyre up in seconds, which is why racers use it.
- Weight and size. A cartridge and a small head weigh less than any electric pump.
- Lower price to start. An inflator head costs a fraction of an electric pump.
Where an electric pump wins
- The exact pressure, every time. Set the number, press start and the pump stops when it gets there. Not sure what pressure to run? Use our tyre pressure calculator.
- More than one fill. A second puncture, a riding buddy with a flat or a soft tyre the next morning: one charge covers several fills.
- No cartridges to buy. At around €2 per cartridge, the cost adds up if you top up often, and every one is waste.
- Air stays in longer. CO2 seeps out of tyres faster than air, so riders often have to re-inflate with air after a CO2 fill. An electric pump fills with normal air from the start.
- Kinder to cold hands. CO2 gets very cold as it expands and can freeze the valve and your fingers. Some sealant makers also advise against CO2 because the cold gas can affect latex sealant.
The cost over time
If CO2 is only your emergency backup and you puncture twice a year, cartridges are the cheaper option. If you also use your pump to top up before rides, help others or ride tubeless and plug punctures often, an electric pump pays for itself over time and never runs out of cartridges halfway through a ride.
Frequently asked questions
Can I use CO2 with tubeless tyres?
You can, and the fast blast of gas helps seat a tyre bead. Because of the cold, some sealant makers advise against it, and CO2 escapes faster than air, so top up with a pump when you get home.
How many tyres can an electric mini pump fill?
The INFLATA Pro S fills up to 8 tyres on one charge. The exact number depends on tyre size, starting pressure and target pressure.
Is an electric pump fast enough for a puncture on a ride?
Yes. A road tyre takes under a minute, and the pump stops at the pressure you set, so you can pack your kit while it works.
Does the Pro S work on Presta and Schrader valves?
Yes, it works with both.
The bottom line
CO2 is unbeatable for racing: light and instant. For most riders who want the right pressure, several fills and no cartridges, an electric mini pump is the more practical choice. Pair it with a tubeless plug tool and you can fix most punctures and get back to riding pressure without a single cartridge.
