With the ability to go anywhere, and inflate everything you need without being plugged into a power source, the Seyvum DP3 Portable Tire Inflator is a great combination of portability and cost-effectiveness. 2000mAh means it does not need to be tied to a car cigarette lighter adapter, and this is improved by a small light design.
On top of that, Seyvum has included a cooling fan to prevent overheating on large jobs, multiple accessories, and most importantly, a place to store it all. In other words, it comes close to our ideal of a small, battery-powered tire inflator—we just wish it was a little faster at refilling a tire.
Seyvum DP3 Portable Tire Inflator: Price and availability
The $55 battery-powered Seyvum DP3 Portable Tire Inflator does a lot for little but costs 40% less than the Fanttik X8 Apex, and about twice as much as the $28 Carsun portable air pump. In addition to other air compressors and gardening products, the company sells battery-powered tools.
Seyvum DP3 PortableTire Inflator: Design and Features
At 5.4 x 4.4 x 1.7 inches, the Seyvum DP3 Portable Tire Inflator is 20% smaller than a Fanttik X8 Apex pump, and positively small compared to a Carson portable air pump or Craftsman V20 cordless inflator. Its heft of 1.3 pounds is a result of the 2,000mAh battery, but it’s still a fairly lightweight device. Certainly compared to the 3.0-pound X8 Apex or the 5.8-pound Craftsman V20. This makes the Seyvum one of the easiest tire inflators to store, carry and use.
While some portable air compressors include a cloth bag, the Seyvum DP3 Portable Tire Inflator has a hard black carrying case. Made of heavy-duty nylon with a padded handle and compartment for accessories.
Instead of relying on passive cooling, the DP3 portable tire inflator has aluminum cylinders, cooling fins and a built-in fan. It can pump and pump without the risk of collapsing, even when other inflators have to automatically shut down to prevent overheating.
The Seyvum’s interface is top-shelf, with a five-button control panel and a 1.9-inch monochrome display. In addition to the battery level, the display shows tire pressure in pounds per square inch (PSI), bars, kilopascals, or kilograms per cubic centimeter (kg/cm3). There are settings for tires of sports cars, motorcycles, bicycles and sports equipment in addition to those that I set myself.
Capable of pumping up to 35 liters per minute, the DP3 Portable Tire Inflator pumps out a pressure of 150 psi. The deflate button for the pump is also a welcome addition, though it lacks the low pressure/high volume mode that can make filling beach toys and air mattresses a slow process.
The kit includes a short air hose and adapters for a raft, bicycle tire, and sports ball, along with a USB C power cord for charging and a car cigarette lighter adapter with a 10-foot cord. There is no AC adapter or USB power port to power other devices. The LED light is bright, though it can’t be set to flash in an emergency.
Seyvum DP3 PortableTire Inflator: Setup
The Seyvum DP3 is small enough to stash in the glove box or under a seat, ready to fill a tire, soccer ball or beach swan at a moment’s notice. While the ball needle valve accessory sports a compartment on the side of the pump, all other accessories and cables fit in the black enclosure. This way all parts are available when needed.
The five-button interface allowed me to turn the power on and off, turn on the light and change the inflation mode. It is easy to use different pressure units and adjust the automatic shut-off pressure. It took a few seconds to set the pump to the correct pressure.
While the battery should suffice for multiple tires, and other inflatables, using a cigarette lighter adapter is an additional option. Its 10-foot cord is long enough to reach all tires on most cars and light trucks while plugged in.
Seyvum DP3 Portable Tire Inflator: Performance
The 12 inch air hose of the Seyvum DP3 inflator is short but should be plenty in most conditions. Its threaded fitting takes a moment to attach to the tire valve stem, but unfortunately it’s not as easy to use as the mounting fittings Black + Decker uses for their 20V Max Inflator.
Once connected, the pump filled my flat tire to 30 psi in 4 minutes, 34 seconds, about a minute longer than Carson’s Craftsman V20 and AstroAI portable air compressor pumps. All the way around, it was among the quietest and most stable pumps I’ve seen, especially compared to the loud Carson pump. It was also the coolest, with the case never getting hot. However, the air hose did get surprisingly hot.
Later, I filled my football to 10 PSI in 13.0 seconds, which puts it on par with the Fanttik X8 Apex inflator. On both tasks, the pressure readings were accurate and the auto shut-off worked well.
The DP3 portable tire inflator comes with a one-year warranty that extends to 18 months if you register the machine. That’s enough, but second rate compared to the three years of coverage included with the Carson Portable Air Compressor and Craftsman V20 Cordless Inflator.
Seyvum DP3 portable tire inflator: The verdict
Small and light enough to stash just about anywhere, the Seyvum DP3 portable tire pump can fill tires and a variety of other inflatables due to high temperature. It comes with a range of accessories and can run on a car’s cigarette lighter outlet or battery power but lacks an AC adapter.
Don’t be in a hurry, because filling up my tire took a lot longer than other portable air compressors even though it wasn’t nearly as loud. Still, at $55, it’s a bargain for those who want to quietly and quietly fill a tire, air mattress, or soccer ball.
