What to know before buying

Listing details to confirm

The listing is inconsistent about pressure, giving 6 Atmosphere in product details and up to 8 bar in feature text. It also gives a 480 Grams weight and 7L x 7W x 28.9H centimetres dimensions, while another feature description says about 0.75 kg and 7 × 7.3 × 28.9 cm. The title uses TX-157, but the model field says 4906. Confirm the selected listing’s exact specification and model before buying.

The supplied evidence contains aggregate ratings but no customer-comment summary. The overall rating and distribution suggest a generally favourable but not unanimous response, without showing what buyers liked or disliked. That gives limited guidance on real-world inflation performance, battery endurance or kit contents, so assess those against your needs and the listing’s inconsistent specifications.

Frequently asked questions

What pressure can the Technaxx inflator reach?

The listing conflicts: one product detail states 6 Atmosphere, while feature text claims up to 8 bar. Confirm the rating for the selected listing before relying on it.

Does it stop automatically at the selected pressure?

The manufacturer describes a digital display for setting a target pressure and an automatic shut-off when that setting is reached.

What can it inflate?

The listing names car, motorcycle and bicycle tyres, balls and other inflatables, with adapters described for common valve types and larger openings.

What comes in the package?

A product detail lists one item. Feature text also claims a storage bag, USB charging cable, cigarette-lighter connection cable, adapters and an instruction manual, so confirm the actual selected package.
