The Oasser Tyre Inflator is number 5 in this guide to bike pumps, and it is the odd one out in a way that helps: it is the product here that genuinely is electric. The listing describes a rechargeable lithium-ion compressor with a Type-C charging port and a 30 cm hose, and its spec table agrees with itself — "Power Source: Powered by rechargeable battery" alongside "Operation Mode: Battery-powered". That is worth pointing out, because two hand-operated pumps elsewhere in this set are filed as "Corded Electric" in their own spec tables. At £19.99 the Oasser claims up to 150 PSI (10.3 bar) from a 17 mm cylinder and a 390-model motor, and carries 4.6 stars from 5,078 ratings.

Two numbers inside the same listing do not line up. The fourth bullet promises "4 different quick air nozzle conversion head sets", while the Included Components line of the spec table lists "3 different nozzles". The airflow figure is 13 litres per minute — roughly 217 cc/s — which cannot be read against the 318 cc/s and 200 cl/s printed for other pumps in this guide. And the star breakdown we hold accounts for 100 ratings (77 five-star, 14 four-star, 5 three-star, 4 one-star) against that headline 5,078. Everything on this page comes from the Amazon listing for this product; none of it is from testing we carried out.

## Questions people ask

**What pressure can the Oasser tyre inflator reach?**

The title and spec table give a maximum of 150 PSI (10.3 bar), and the preset modes are adjustable from 3 to 150 PSI. The listing says this comes from a 17 mm cylinder and a long-axis 390-model motor.

**Does it come with nozzles for bikes and cars?**

The spec table lists 3 different nozzles, a hose, a storage bag and a Type C cable. The fourth bullet describes "4 different quick air nozzle conversion head sets", so the listing gives two different counts of the same thing.

**Is the Oasser LS4102 cordless?**

Yes. It is listed as powered by a rechargeable lithium-ion battery with a Type-C connector, and the operation mode is given as battery-powered.

**How much air does it move?**

13 litres per minute as listed, which works out at roughly 217 cc/s. The guide's other pumps quote 318 cc/s and 200 cl/s, so these headline figures are not directly comparable as printed.

**How big and heavy is it?**

525 g, 12 x 8.5 x 4.5 cm, with a 30 cm hose. The listing describes four preset modes: custom, car, bicycle and ball.

**What does it cost and how is it rated?**

£19.99, rated 4.6 out of 5 from 5,078 ratings. The star breakdown we hold covers 100 of those ratings: 77 five-star, 14 four-star, 5 three-star and 4 one-star.
