Five autocompressors to maintain the desired tyre pressure

To help car owners, the MC8850 compressor model has been singled out from the numerous Strum power tool guard. This is a high performance electric pump for a wide range of machines from small to large.

The autocompressor connects directly to the battery terminals using a 2.9-meter long power cord with alligator clips. In order to get to all the wheels of the "iron horse", the device was equipped with an air hose 3 m long in the form of a coil spring. The Sturm MC8850 comes with a variety of attachments to inflate bike wheels, air mattresses and balls.

The quartet of support legs gives the metal compressor housing more stability on hard surfaces. And for ease of carrying in the design of the product, a gripping handle was provided. For the period of inactivity, the autocompressor "rests" in the bowels of the bag-cover from the factory. It also houses the accompanying attachments.

Now about the performance of the device. Its engine is capable of inflating the tyre up to a maximum pressure of 10 atm with a high capacity of 50 l/min. A completely flat tyre of an ordinary passenger car will be pumped up to two "plus" atmospheres in just a couple of minutes. Off-road tyres can be inflated with the Sturm MC8850 in 4-5 minutes. Plus, you definitely won’t go broke buying a compressor.

70Mai is a "daughter" of Xiaomi, which has relied on various car accessories. One of them is the Air Compressor Lite portable air pump in the form factor of a small square box.

The black “back” of the device is crowned with a screen with illuminated readings of an electronic pressure gauge. The pressure figures on it are displayed in three quantities : kPa, bar (1 bar is approximately equal to 1 Atm) and PSI in the American manner (pound force per square inch). Switching between units of measure is done by pressing the R button in a row of four mechanical keys below the display. The remaining buttons are designed to set the required pressure and start / cancel the wheel inflation procedure.

The electric motor "under the hood" of the model provides air supply in a volume of up to 25 l / min through a hose of approximately 70 cm in length. The air duct tube is wrapped around the perimeter of the back of the device in a special recess. The power cable with a plug for the car cigarette lighter and replaceable nozzles for the tip of the air supply hose are hidden under a removable cover at the bottom of the Xiaomi 70Mai Air Compressor Lite. Questions are raised only by the reliability of the latch of the cover for accessories.

The operation of the autocompressor requires a minimum of intervention - just set the required tyre pressure and the autostop function will stop pumping air into the wheel when it is reached. To pump up a flat tyre of size 15 in a passenger car, the device will need only 3-4 minutes. As a result, Xiaomi 70Mai Air Compressor Lite will be an excellent gift for any motorist for adequate money.

In the assortment of Hyundai brand car accessories there is a good trinity of compressors for pumping wheels: the younger model HY 1540 is suitable for small cars and small sedans, the middle brother HY 1645 is for a wide range of cars, and the “adult” HY 1765 pump is for cars, SUVs and cars. SUVs.

The older model of the trio is assembled in a high-strength metal case of a standard barrel-shaped layout. The engine of the device has a piston design, provides high performance compressed air supply (about 55 l / min.) And is able to bring tyre pressure up to 10.2 atm. Although in fact the scale of the onboard pressure gauge of the compressor is marked only up to 5 atm. The model spends 2 minutes to inflate one wheel in size R15, tyres R17 - 3-4 minutes. The compressor motor can run continuously for up to 40 minutes.

Power is supplied to the autocompressor from the cigarette lighter socket via a 3-meter-long wire. The air supply hose on the Hyundai HY 1765 is 1.2 m long. One of the complete nozzles can be put on the tip of its “tail” - a needle for balls, heads of various sizes for pumping all kinds of inflatable products. A spare 15A fuse is also included with the device.

A built-in LED-light comes to help in ensuring the visibility of the work front at night. In addition to the autocompressor, there is a fabric bag-case for easy storage of the product, along with accessories in the trunk of a car. The model solves the “headache” with tyre inflation, costs reasonable money and does not let you down at the right time.

Model R15 is transitional between Berkut compressors of the basic level and high-performance electric pumps. It will fit cars, minibuses and small commercial vehicles.

The powerful engine of the device allows you to inflate a car tyre with a “running” radius R15 from 0.8 to 2.0 atm in just 1 minute. In this case, the pressure readings are displayed on the analog pressure gauge scale. It is marked up to 7 atm, although the compressor itself can pressurize tyres up to 10 atm. The operation of the autocompressor without a break is possible for 15-20 minutes. In case of premature overheating, it provides a special automatic thermal protection.

The power supply to the Berkut R15 engine is established in two ways: from the car cigarette lighter socket from the car interior or from the battery terminals. Fortunately , the network cable of the model has a length of 4.8 m - the device can easily reach the farthest wheel of the car. The length of the flexible hose-air duct of the compressor is 1.2 m. At its tip there is a deflator valve to relieve excess pressure.

Under load, the device consumes a decent current (up to 14.5 A), and therefore it is not recommended to use it for a long time paired with small-capacity batteries with the engine turned off. In contrast to the above , it is necessary to note a convenient bag for carrying the compressor with a brief instruction manual right on the inside. Even more forces to keep large-radius wheels in good shape are in the assets of Berkut R20 and R24 autocompressors.

The Black&Decker ASI400 electric portable pump is useful both for motorists and at home. In the first case, it will help maintain the desired pressure in the tyres of the “iron horse”, and in the second case, it will come in handy for inflating inflatable products that do not require high pressure.

The body of the model is made of durable ABS plastic with a convenient carrying handle. On its “facade” there is an electronic pressure gauge with backlight, a recess for adapters, two holes for air supply hoses and a three-position power / air supply button. Why are there two air holes? Because a duo of hoses is connected to the product - for injecting high pressure in tyres and for inflating inflatable objects in the manner of mattresses or, for example, basketballs.

The auto-stop function in the Black&Decker ASI400 assets allows you to set the required level of inflation pressure. When the set pressure is reached, the compressor switches off automatically. The maximum possible for the model is a pressure of 11 atm. The energy cable of the autocompressor with a plug for connecting to the cigarette lighter socket is twisted from the back of the case into a neat bay. Its length is about 5 m.

The weight of the device in conjunction with all related devices is 1.8 kg. It will not become a heavy burden and will take up a minimum of space in the trunk of a car. The “excellent” model copes with maintaining the required pressure in the wheels of the car and will come in handy during the same trips to nature, assisting in pumping volumetric products with low pressure.
