If you’re after a compact, cordless inflator that slips easily into your glovebox or backpack, the SCK619-3 Portable Air Pump is a readily available option that balances speed, convenience, and battery life.
In this review, we put this sub-$10 pump to the test.
Box & Unboxing
The SCK619-3 Portable Air Pump comes in a sturdy, glossy colour box that shows the device, highlights its key features, and notes that it can be used on tyres as well as household items like inflatable balls.
Opening the box we find:
- The portable air pump
- Instruction manual
- USB Charger
- Three additional nozzles for inflating a variety of items
Key Features & Specifications
Some of the pump’s key features include:
- LED display showing current and set tyre pressure
- Automatic stop when the set pressure is reached
- Option to display tyre pressure in different units (PSI, BAR, kPa, kg/cm²)
- Built-in lithium battery
How It Works
The SCK619-3 Air Pump has one simple purpose: pumping up tyres, and it does the job very well.
First, set the tyre pressure on the device using the up and down arrows on the display. Once the pressure is set, connect the pump to the tyre and press the brown button on top of the device to start. On a motorcycle tyre at full battery power, the pump increased pressure by roughly 1 psi every two seconds in 0.5 psi increments. Once the target pressure was reached, the pump switched off automatically.
Charging is simple via the included USB adapter and the barrel connector on top of the device. A full charge took around six hours.
Battery life is very good, with the pump able to top up several car and motorcycle tyres on a single charge. Unlike other lead-acid portable pumps I’ve used, the SCK619-3’s internal lithium battery maintains strong performance throughout the charge without noticeably slowing down as the battery drains.
Thanks to the included nozzles, the pump can also inflate household items such as footballs or even a giant pink flamingo pool toy. A small but welcome feature is the lever-style action on the Schrader valve, which is far more convenient than the twist-on style found on similar pumps.
Tear Down
Unscrewing and opening the pump gives a clear view of how it works.
The key components include:
- Lithium battery, advertised as 7.4V 1500mAh, made up of 2x 18650 cells in series
- Brushed DC motor
- Reduction gearbox and piston pump
- Electronic pressure sensor
- Digital controller and LCD screen
The design of the SCK619-3 Air Pump is straightforward but well thought out, built to a high-quality standard. As the pump lacks active cooling, it’s important to respect its duty cycle and allow it to cool for a few minutes between uses.
Who Makes It
The SCK619-3 Air Pump is often sold under various names by different online retailers. While the box itself is unbranded, the pump lists the manufacturer as Yiwi Rongzhi Electrical Appliance Co., Ltd, located at No. 42, Baaima Road, Fotang Town, Yiwu City, Zhejiang Province, China.
At the time of writing, we were unable to find further information about the vendor.
Final Thoughts
Overall, the SCK619-3 is an excellent value portable air pump that performs reliably. Its key selling points are the built-in lithium battery, which works independently of a power source, and the LCD pressure gauge.
While the pump performs well, it faces stiff competition from similar portable models that are more compact and offer extra features such as built-in flashlights, USB charging, and the ability to act as a jump starter.
What’s Hot
- One of the cheapest air pumps on the market
- Built-in lithium battery with a practical battery life
- Accurate pressure gauge with multiple units of measurement
- Sturdy and reliable construction
What’s Not
- A USB-C charging option would be nice to avoid a special adapter
- Clunky to use and not very compact compared to other models
- Poor English on the box and manual.
FAQ
Q: How loud is the pump when in use?
A: The pump is noticeably audible, similar to other small portable inflators, but not uncomfortably loud for short sessions.
Q: Can I replace the battery if it wears out?
A: No. The lithium battery is internal and soldered in, so replacement is not straightforward.
Q: Are replacement nozzles and hoses available?
A: The pump will use standard Schrader valve adapters however the main inflator hose is not removable or replaceable.
Q: How accurate is the pressure reading?
A: The LED display provides readings in multiple units (PSI, BAR, kPa, kg/cm²), suitable for everyday tyre maintenance. The unit we received was accurate to within 1psi of another meter we compared it with.
Q: Can the pump deflate or lower the pressure in a tyre?
A: No, the pump can only increase the air pressure and does not have the functionality to deflate the tyre if you wish to lower the air pressure.
