Car Air Compressor 12V 150PSI - 4WD Portable Tyre Deflator Inflator Truck Pump

This is a twin-cylinder pump that clamps to the battery and works to 150 PSI, and the specification block is generous about nearly everything except the one thing you want to know at the side of a track: how long a tyre takes. Air flow is described as huge and given no figure at all — no litres per minute, no cubic feet, no fill time, and no tyre size it was measured against. What the page does bound is how long you may run the pump, and it bounds it twice, differently.

Twenty minutes, or ten

The specification line reads Continuous Working Time: 20 min. Four lines lower a numbered note suggests the using time should not be over 10 Minutes, and that past ten you switch off and let it cool. Both statements are printed here, both are about the same thing, and neither has been chosen over the other. Staying inside both at once means stopping at ten, which is arithmetic on the page's own pair rather than a ruling on which of them is right.

The two warnings, in the supplier's words

Three numbered lines close the description and two of them are warnings. The first is about supply: do not use this item with 24V, 36V, 110V and 220V electric sources, just use with DC 12V 14A electric sources. The second is the duty limit above. Neither is paraphrased. Notice what is not among them — the pump draws 14 amps through battery clamps, and no fuse, breaker or protection of any kind is named on this listing.

Key features

• Two cylinders: the description calls it a twin cylinder and a double cylinder, which is where the 150 PSI working pressure comes from.
• Straight to the battery: a pair of battery clamps is in the pack, so the pump takes its 14 amps from the terminals rather than a socket.
• Cast casing and radiator: the pump body is cast metal with a radiator, which the page credits with better heat dissipation.
• Two hoses, two jobs: a half-metre black air hose and a metre-and-a-half yellow coiled hose both come with it.
• Three metres of lead: the cable length is stated in the specification block and again in the pack line.
• Nozzle adaptors: three arrive, and no other pack line carries a quantity above one.
• Everything in a box: a black storage box and a tyre repair tool set are itemised in the contents.

Specifications

• Top working pressure: 150 PSI
• Supply it asks for: 12V DC
• Current draw: 14A
• Stated continuous working time: 20 min, against a note below it that says ten
• Size of the pump body: 21.5 x 8.5 x 20cm, approximate
• Power cable: 3m
• Straight hose: 0.5m black
• Coiled hose: 1.5m yellow
• Pump casing: metal

Where this listing leaves a hole

• The colour line is stored as Color: Black Silver, with both spaces standing and whatever joined the two words gone. It is not repaired here, and no copy on this page says the pump is black and silver, or black or silver.
• A tyre deflator is what the title sells, and both store summaries agree with it. Nothing in the description deflates anything, so what we carry above is the smaller claim.
• Feature five says the accessories arrive in the carry bag; the pack list gives a black storage box. There is no bag in the contents and no box in the features.
• Two models sit behind the buy button. The word model occurs nowhere in the description, so whatever separates them is not written down.
• No fuse rating, no circuit breaker and no duty cycle as a percentage or a ratio.
• No gauge, no dial and nothing about how the pressure is read.
• No flow rate, no fill time, no weight, no warranty, no standard and no country of origin.
• A closing note asks you to allow minor deviation due to manual measurement. It is carried, because the page prints a pump size and four lengths as numbers, and it puts no magnitude on the deviation it asks for.
• Two places have lost a word. The opening paragraph reads nomal where the numbered feature below it spells the same word normal, and the duty warning reads cool it to 10 minutes. Neither has been repaired, and the warning is reproduced with the fault in it rather than tidied.

Bought for what it is — a battery-clamp pump with real hoses and a box to keep them in — the description is unusually detailed about the hardware and unusually quiet about performance. The figure it withholds is the one deciding whether four tyres means one session or three; the figure it prints twice is how long you may keep going.
