ETENWOLF Vortex S6 Cordless Heavy-Duty Air Compressor
Truck, SUV and off-road tires away from any power outlet
The Vortex S6 is a 19,200 mAh battery compressor with separate high-pressure and high-volume hoses, six preset modes reaching 160 PSI and a maker-stated ±1 psi sensor. Tire modes stop at your preset; the high-volume mode does not, and the manual says you must pause it yourself.

Fit and limits
Strengths
- Six preset pressure ranges up to 160 PSI, with the target remembered between uses
- Maker states a ±1 psi sensor accuracy in both the manual and the product page
- Separate high-volume hose and a deflation mode for mattresses and floats
Caveats
- High-volume mode has no auto-stop; the manual says you must pause it yourself
- Cannot be used while charging, and the altitude recalibration resets at every power-off
- The 100 percent duty-cycle claim is a listing claim; the manual states no duty cycle
A two-hose battery compressor, not a glovebox pump
The manual calls this the Vortex S6 and gives the body as 309 by 237 by 142 mm excluding the air tube; Amazon's table lists 11.8 by 5.5 by 9.45 inches and six pounds. It has two separate air circuits: a high-pressure hose for tires and balls, and a high-volume hose that fits a wide outlet port for low-pressure, large-volume items. The high-volume tube is 450 mm long in the manual's specification table, which matches the 45 cm hose length on Amazon; the manual gives no length for the high-pressure hose.
The manual's package list is the compressor, an air chuck, a high-pressure hose, a high-volume hose, a 45W PD charger, a 1.8 m USB-C to USB-C cable and the manual, with the high-volume tapered nozzle, high-pressure tapered nozzle, inflation needle and Presta valve adapter stored on a panel on the back. ETENWOLF's product page lists broadly the same parts but adds a carry bag, which the manual's package list does not mention, and Amazon's included-components field lists neither the high-volume hose nor the cable. Check what arrives against the manual's list.
There is also an external power connector on the body, described in the manual's overview as 12V/20A DC, so the pump is not battery-only if you have the right lead. The manual does not describe that lead as included.
Six preset modes, each with its own pressure window
The mode button cycles six inflation modes plus a high-flow inflate/deflate mode. The manual's preset table gives each one an adjustable range and a default: car 8-50 psi with a 35 psi default, pickup truck 10-85 psi at 35, recreational vehicle 20-130 psi at 60, bicycle 10-145 psi at 22, ball 3-16 psi at 8.5, and manual mode 0-160 psi at 30. The deflation mode has no pressure setting.
That table is the real answer to what the S6 will and will not do. If a mode will not let you dial the number you want, the manual's troubleshooting page says to check that the right mode is selected and that the value is inside its range. The unit button switches between PSI, kPa and Bar, and the manual warns that mixing up psi and bar could lead to dangerous over-inflation.
Pressure sensor accuracy is stated by the maker as plus or minus 1 psi, in both the manual's specification table and the product page's comparison block. The overall inflation pressure range is 3-160 PSI, and the troubleshooting page notes that anything under 3 psi simply displays as zero.
The auto-stop applies to tires; high-volume mode does not stop itself
In high-pressure mode the sequence is: set the mode, set the unit, turn the knob to your target and press start. The manual says the unit turns off automatically when the inflated item reaches the preset value, and that it remembers your last target pressure and unit for next time. You can press the start/pause button to stop at any moment, and the display shows target above and actual pressure below.
High-volume mode is different, and the manual is blunt about it. Its note reads that users need to pause the inflation manually and that leaving it will lead to the inflated item bursting. There is no preset value in that mode. If you are filling an air mattress or a float, you have to stand over it, which is worth knowing before you buy this for camping duty.
The manual also lists six conditions in which the inflator shuts itself off, including five minutes of inactivity, and two protective ones: inflating for over five minutes while actual pressure is still below 5 psi, and inflating for over five minutes while actual pressure is above 160 psi. Another useful note: after a tire is inflated, its pressure falls by roughly 0.5 to 1.5 psi as the air inside cools back to ambient.
The duty-cycle claim, temperature limits and the ten-minute reset
Amazon's bullet claims a 100 percent duty cycle with no need for breaks, and ETENWOLF's product page says the cooling system allows continuous, uninterrupted inflating with no overheating. The manual we read does not state a duty cycle at all. What it does have is a temperature protection indicator on the display and a troubleshooting row for the inflator stopping because of extreme temperature conditions. Those statements are not the same thing, and we do not pick one for you.
The manual's own numbers are the practical limits. Discharging — inflating, deflating or using the power bank — is specified for -4°F to 158°F (-20°C to 70°C); charging is specified for 32°F to 113°F (0°C to 45°C); storage is -4°F to 140°F (-20°C to 60°C). Its safety instructions add not to leave the product for long periods in a hot car, and to turn it off immediately if there is unusual noise or the temperature becomes very high during inflating.
If the safety alert symbol lights because abnormal pressure or abnormal motor behaviour is detected, the manual's instruction is to power the machine off, wait ten minutes and restart it. The safety instructions also say not to leave the pump unattended while it is operating.
Battery, charging and the power-bank side
The specification table lists the S6 battery at 19,200 mAh (71 Wh) and gives a charging time of about two hours from empty with the 45W PD charger, which the manual says is included. Input is Type-C PD3.0 at up to 45W. The same table lists an S6 Plus at 26,400 mAh (97 Wh) and 2.5 hours; the ASIN here is the 19,200 mAh S6.
Two things the manual says about charging are easy to miss. The inflator cannot be used while it is charging, and it turns itself off after two minutes of inactivity once fully charged. The battery bar shows four segments of 25 percent each and flashes below 10 percent, and the manual explains that the reading is lower while inflating than at rest because voltage sags under load.
As a power bank it must be switched on to work. The manual's power-bank page lists USB-A output at 5V 2A and USB-C at up to 45W (5/9/12/15V 3A, 20V 2.25A); the specification table on the next page gives USB-A as 5V/2.4A, so the document does not fully agree with itself on that one figure. The LED work light has four modes, with the manual quoting 300 lumens bright and 1000 lumens ultra-bright, and noting the light switches off automatically after one hour the first time — after that, if you turn it on again it stays on until the battery is exhausted.
Altitude recalibration, care rules and two different warranty statements
The manual has a recalibration routine because altitude can shift the reading by 1 to 3 psi. Above 5,000 feet it says users are able to recalibrate by holding the light and mode buttons together for ten seconds with no hose connected and the pump powered on. The catch is in the notes: the new calibration is not remembered, so it resets to sea level every time the pump is switched off and has to be redone at each power-on. If you live at altitude, that is a per-use chore.
The safety instructions say the product is not a toy and users should be over 16, not to wash it with water or expose it to rain, to store it indoors, and to keep it out of dusty or explosive atmospheres because the DC motor can spark. For a battery left in storage, it asks you to charge it at least once every three months. It also states that malfunction caused by not following those requirements is not covered by the warranty, and specifically requires an ETENWOLF or certified PD charger with the included cable.
The warranty wording differs between documents. The manual's warranty page says two years of coverage with repair or replacement of a product defective through a manufacturing fault, while the manual's own cover page says to register at etenwolf.com to receive a one-year extended warranty. The product page describes a two-year extended warranty available on registering the product and also sells a one-year extension separately. Amazon's details field says two years. Read the registration terms before assuming the longer figure applies automatically, and check the seller and condition of the offer you choose. The manual names the manufacturer as Mozhen Technology (Shenzhen) Co., Ltd.
