Kraton AC14010/35DD – budget with a digital pressure gauge.
Aggressor AGR-40 Digital.
The K70 pump is the best in terms of functionality with a digital pressure gauge.
AVS KE350EL A80825S is an alternative to the best feature set with a digital pressure gauge.
BERKUT SPEC-19 .
Daewoo DW40L – with a removable pressure gauge.
Aggressor AGR-50L is the optimal set of functions among models with an analog pressure gauge.
Carmega AC-50 is an alternative to the optimal set of functions among models with an analog pressure gauge.
Stvol Q5.
Kraton AC14010/35DD
Despite the lowest price in the selection, this piston compressor has decent characteristics. Capacity – 35 l/min, maximum pressure – 10 atm, continuous operation time – 25 minutes.
On the body there is a digital pressure gauge and an LED flashlight with two modes – normal and signal. The model is connected to the cigarette lighter. There is a short circuit protection system and automatic shutdown when the specified pressure is reached. The cord length is 3 m. The kit includes adapters for inflatable furniture and balls.
Jock K70
K70 is a two-piston compressor with a capacity of 40 l/min, a maximum pressure of 10 atm and a continuous operation time of up to 30 minutes. There is an overheating protection system and automatic shutdown when the specified pressure is reached. You can connect it either to the cigarette lighter or directly to the on-board battery. Cord length – 2.8 m.
The screen of a digital pressure gauge with two scales located on the compressor body, in addition to pressure, shows the charge level of the car battery and the voltage of the battery and generator. A dual-mode LED flashlight is also built into the body. The kit includes adapters for inflatable furniture and balls.
Alternative. The maximum pressure and continuous operation time of the AVS KE350EL A80825S are the same as the previous model, and the productivity is slightly lower – 35 l/min. The cord length is 3 m. There is a protection system against short circuit and overheating and automatic shutdown when the specified pressure is reached. The housing has a built-in digital pressure gauge and LED flashlight. The kit includes adapters for air mattresses, boats and balls.
Daewoo DW40L
The only device in our selection with a removable digital autonomous pressure gauge powered by batteries. The DW40L piston system provides a capacity of 40 l/min, a maximum pressure of 7.5 atm and is capable of continuous operation for 20 minutes.
The model can only be connected to the cigarette lighter socket. There is a short circuit protection system and automatic shutdown when the specified pressure is reached. The length of the cord is 3.5 m, the length of the hose is 45 cm. An LED flashlight is built into the compressor housing. The kit includes adapters for inflatable furniture and balls, as well as four spare nipple caps.
Aggressor AGR-50L
Piston compressor with analog pressure gauge located at the end of the hose with a threaded nozzle. Capacity of AGR-50L is 50 l/min, maximum pressure is 10 atm, continuous operation time is 30 minutes.
The model is connected directly to the on-board battery, it has its own fuse to protect against overload and short circuit, as well as an overheating protection system. Cord length – 3 m, hose length – 5 m.
An LED light is built into the compressor housing. The pressure gauge can be used separately together with a deflator – a tire pressure regulating valve. Sold complete with adapters for inflatable furniture, boats and balls.
Alternative. The Carmega AC-50 differs from the previous model in that it does not have a flashlight and the hose is a meter shorter. Otherwise, this compressor is similar to the Aggressor AGR-50L.
Location and type of pressure gauge. Compressors are equipped with analog or digital pressure gauges. Models with a digital pressure gauge are more convenient, but more expensive. The pressure gauge can be located on the device body, air supply hose or air gun. In the first case, the pressure sensor is located in the cylinder, in the second and third cases it is installed in front of the fitting. Models with a pressure gauge on the body may overestimate the readings, since when the compressor is operating, the pressure in the cylinder is higher than in the hose. To find out the real pressure, such a compressor must be turned off.
We looked at compressors with both digital and analog pressure gauges.
