Eyshwu D04 Tire Inflator Portable Air Compressor Review
A low tire warning is stressful when you are already late, parked far from a pump, or dealing with bad weather. The Eyshwu D04 Tire Inflator Portable Air Compressor is built for that moment, with a 5400mAh rechargeable battery, 12V DC backup power, auto shut-off, and a 150 PSI maximum pressure rating.
This review looks at verified specs, everyday usability, safety features, and real tradeoffs. The D04 has strong emergency value because it is compact, cordless, and easy to store, but its 85 dB noise level and 50 cm hose are worth knowing before you buy.
Quick Verdict
Rating: Recommended with caveats, 7.8/10
Best For: Drivers, commuters, cyclists, and new car owners who want a compact 150 PSI inflator with cordless use and 12V backup power.
Bottom Line: The Eyshwu D04 is a smart glove-box inflator for routine top-offs, road trips, bikes, balls, and emergency use. It is not the best fit if you need a quiet compressor, a long hose, or heavy-duty inflation for large tires.

What Is the Eyshwu D04 Tire Inflator?
The Eyshwu D04 is a portable air compressor for car tires, motorcycle tires, bicycle tires, sports balls, and small inflatables. It sits in the compact emergency-inflator category, where the goal is easy storage, fast pressure top-offs, and enough backup power to help you get moving again.
The main strength is dual power. You can use the built-in 5400mAh battery for cordless inflation, then switch to the included 12V DC car power cord when the battery runs low or you need steady roadside power. At 6.45 x 3.3 x 1.77 inches and 1.2 lb, it is small enough for a glove box, center console, trunk kit, or road-trip bag.
The kit also includes the practical pieces most buyers need: a flexible hose, Type-C charging cable, ball needle, Presta valve adapter, plastic nozzle, and user manual. Built-in nozzle storage is useful because small adapters are easy to lose when you keep a pump in a trunk or garage drawer.
What This Tire Inflator Includes
The package includes the portable tire inflator, 12V DC car power cord, flexible air hose, Type-C charging cable, ball needle, Presta valve adapter, plastic inflatable nozzle, and user manual. Built-in nozzle storage helps keep the small adapters with the pump instead of loose in your trunk.
That kit gives you enough flexibility for car tires, SUVs, motorcycles, bicycles, sports balls, and pool-style inflatables. The Presta adapter is especially useful for road bikes, while the ball needle covers basketballs, soccer balls, and similar gear.
The setup is simple: connect the hose, choose the correct mode, set the target PSI, and start inflation. The auto shut-off feature stops the pump at your selected pressure, so you do not need to keep checking a separate gauge during a basic top-off.
Who Should Buy It?
Best For
- Drivers who want a compact emergency tire pump with both cordless battery power and 12V DC backup.
- New drivers, commuters, and road-trip users who want auto shut-off instead of checking pressure by hand.
- Cyclists or families who need one small pump for car tires, bike tires, sports balls, and small inflatables.
Skip If
- You drive a truck, RV, or large vehicle and need a longer hose or a heavier-duty compressor.
- You want a quiet inflator, because the listed 85 dB noise level is noticeable during use.
- You need a shop compressor for air tools, repeated full tire fills, or long continuous work.
Before You Buy: The D04 is best for top-offs and emergency inflation, not heavy-duty shop use. The 50 cm hose can also feel short around larger wheels or awkward valve positions.
How Fast and Powerful Is It?
Inflation Speed and Pressure
The Eyshwu D04 uses a 19-cylinder motor and has a listed maximum pressure of 150 PSI. The strongest speed claim is for a 195/65 R15 tire, which the listing says can go from 0 to 36 PSI in about 6 minutes.
For most drivers, the more common job will be a top-off from a few PSI low rather than a full tire fill from zero. In that use case, the 150 PSI rating gives you enough pressure headroom for typical passenger cars, SUVs, motorcycles, bicycles, and sports balls.
Accuracy and Auto Shut-Off
The D04 includes an LCD digital display and auto shut-off with stated ±1 PSI precision. You set the target PSI, start the pump, and let it stop when it reaches the selected pressure.
This matters because overinflation and underinflation can both affect tire wear, handling, ride comfort, and fuel efficiency. Auto shut-off also makes the pump easier to use at night or in bad weather because you do not need to keep checking a separate gauge during a basic top-off.
Preset Modes and Controls
The four smart modes cover car, motorcycle, bike, and ball inflation. These presets make setup faster because each category uses different pressure ranges and adapter needs.
You should still check the correct PSI before starting. For vehicle tires, use the pressure on your driver-side door placard when available, not the maximum pressure molded into the tire sidewall.
Battery Life, Backup Power, and Charging
5400mAh Battery
The built-in 5400mAh battery is the main convenience feature. The listing states that one full charge can support more than four car tires under its stated conditions, which makes the D04 practical for routine tire checks and roadside top-offs.
Battery performance can drop in cold weather, so it is smart to keep the unit charged before winter drives. For best results, do not store it fully drained for long periods, and check the charge before long road trips.
12V DC Backup
The included 12V DC car power cord is the D04’s safety net. If the battery runs low while you are away from home, you can plug the pump into your vehicle’s 12V outlet and keep inflating.
This dual-power design is more dependable than a battery-only mini inflator. It gives you cordless convenience for quick jobs and wired backup for longer roadside use.
Power Bank Function
The 5400mAh battery can also work as a 5V/2A emergency power bank. That will not replace a dedicated high-capacity charger, but it can help add useful power to a phone during a roadside delay.
This feature is best viewed as backup utility, not the main reason to buy the inflator. The D04’s strongest value still comes from tire inflation, auto shut-off, and the 12V cord.
How Easy and Safe Is It to Use?
[Products Worth Considering]
The ETENWOLF S1 cordless tire inflator delivers ultra-fast inflation with up to 160 PSI and a 20 L/min airflow for quicker tire top-offs. Its 5200mAh battery and cooling system support inflating many tires and sports balls on a single charge, while the digital pressure gauge and multi-unit display help you reach the right pressure accurately. With preset modes, pressure memory, an auto-stop feature, and an LED flashlight, it’s built for easy roadside and everyday use.
This portable cordless tire inflator delivers fast, efficient inflation for cars, motorcycles, bikes, and sports balls with a digital pressure gauge. Use the one-click PSI preset with auto shut-off for accurate, hands-free topping to your target pressure up to 150 PSI. It’s compact and rechargeable with a built-in emergency LED light plus valve adapters and accessories for quick, ready-to-go use.
Display, Controls, and LED Light
The LCD display shows pressure for quick checks, and the backlit screen helps in low light. The built-in LED light is useful when you are working near a tire at night, in a garage, at a campsite, or on the shoulder of the road.
To use it safely, attach the hose firmly, choose the correct adapter, set the target PSI, and keep your fingers clear of the nozzle while the pump is running. The listed 85 dB noise level means you should expect a loud compressor sound during inflation.
| Step | Action | Result |
|---|---|---|
| 1 | Check the target PSI | You avoid guessing or overfilling |
| 2 | Attach the hose and correct adapter | You create a secure seal |
| 3 | Start inflation and let auto shut-off work | The pump stops at the selected pressure |
Size and Storage
At 1.2 lb, this inflator is easy to move between vehicles or pack for a trip. The 6.45-inch length keeps it much smaller than a traditional 12V compressor box.
The built-in accessory storage helps prevent lost nozzles, which is a real advantage if you plan to use it for bikes and balls as well as car tires. The main storage limitation is the 50 cm hose, which can require careful pump placement near larger wheels.
Pro Tip: Store the D04 with a partial or full charge, keep the 12V cord in the same pouch or compartment, and check your tire placard before setting PSI. This prevents the two most common mistakes: a dead inflator and the wrong pressure target.
How It Performs in Real Use
For Weekly Tire Top-Offs
For routine maintenance, the D04 is at its best. You can set the target pressure, top off one or more tires, and avoid driving to a gas station just to add a few PSI.
During Roadside Emergencies
The 12V DC backup cord and LED light make the D04 more useful during a late-night low-pressure warning. It is not a substitute for repairing a puncture, but it can help you add air long enough to reach a safer location.
For Bikes, Balls, and Small Inflatables
The included Presta adapter, ball needle, and plastic nozzle widen its usefulness beyond car tires. You can use one compact tool for road bike tires, sports balls, and small inflatables instead of keeping several separate pumps.
For Road Trips and Family Cars
The compact size makes the D04 easy to keep in a trunk, center console, or emergency bag. It is especially useful for families, new drivers, and commuters who want a simple backup tool without storing a bulky compressor.
Compatibility and Safety
The D04 is designed for cars, SUVs, motorcycles, bicycles, sports balls, and small inflatables. It is not designed for air tools, large-volume commercial inflation, or repeated heavy-duty use on large tires.
Before inflating a vehicle tire, inspect it for visible damage, screws, nails, sidewall bulges, or rapid air loss. If the tire is punctured or loses pressure again quickly, adding air is only a temporary step and you should get the tire inspected or repaired by a qualified tire professional.
Use the correct adapter, keep the hose connected straight, and avoid pulling the pump by the air hose. Because compact compressors can get warm during use, follow the manual’s operating guidance and allow the unit to rest if it feels hot.
Pros and Cons
Pros
- 150 PSI maximum pressure covers cars, SUVs, motorcycles, bikes, and sports balls.
- 5400mAh battery supports cordless use for routine tire checks and top-offs.
- 12V DC backup cord keeps the pump usable when the battery runs low.
- Auto shut-off with stated ±1 PSI precision helps reduce overinflation.
- Included Presta adapter, ball needle, and inflatable nozzle make it more versatile.
Cons
- The listed 85 dB noise level is loud enough to be noticeable in garages or quiet areas.
- The 50 cm hose may feel short around larger wheels or awkward valve positions.
- It is better for emergency use and top-offs than repeated heavy-duty tire inflation.
Is It Worth the Price?
The Eyshwu D04 offers strong value for the price if you want one compact tool for tire top-offs, emergency inflation, bikes, and sports gear. The combination of 150 PSI pressure, 5400mAh cordless power, 12V DC backup, auto shut-off, and included adapters makes it more useful than a basic manual pump.
Its value is strongest for everyday drivers who want preparedness without carrying a bulky compressor. You get several convenience features in a small body, but you still need to accept the short hose and compressor noise.
If your priority is a small emergency kit for a passenger car or family vehicle, the D04 is worth considering. If you need a long hose, lower noise, or heavy-duty inflation for large tires, a larger 12V compressor will make more sense.
How It Compares to Alternatives
If you want a bigger listed battery, the OlarHike 6000mAh dual-power inflator is a close alternative. If you prefer a well-known accessory brand, the AstroAI L7 offers a similar mini cordless format with 150 PSI pressure and an LED light.
The Eyshwu D04 makes the most sense if you want the specific mix of 5400mAh battery power, 12V backup, 5V/2A power bank output, built-in nozzle storage, and a compact 1.2 lb body. It is a practical middle-ground choice rather than the most heavy-duty option.
Frequently Asked Questions
Can the Eyshwu D04 inflate car tires from flat?
Yes, the listing states that its 19-cylinder motor can inflate a 195/65 R15 tire from 0 to 36 PSI in about 6 minutes. In real ownership, it is still best used for top-offs and emergency inflation rather than repeated full fills from flat.
Does the Eyshwu D04 work when the battery is low?
Yes. The included 12V DC car power cord lets you power the inflator from your vehicle when the internal 5400mAh battery is low. That backup cord is one of the main reasons it is more useful than a battery-only mini pump.
Is the 50 cm hose long enough for SUVs?
The 50 cm hose should work for many vehicles, but it can feel limiting on larger SUVs or wheels with awkward valve positions. You may need to place the pump carefully near the tire instead of setting it farther away.
How loud is the Eyshwu D04 during operation?
The listed noise level is 85 dB. That is normal for many compact compressors, but it is loud enough that you should expect noticeable sound during inflation.
Does it work with Presta valves on road bikes?
Yes. The package includes a Presta valve adapter, so you can use it with many road bike tires as well as standard Schrader valves. Check your bike tire’s pressure range before inflating.
Can it replace a full-size garage air compressor?
No. The Eyshwu D04 is a portable inflator for tires, bikes, balls, and small inflatables. It is not meant for air tools, shop work, or repeated large tire fills.
What comes in the box?
The kit includes the portable tire inflator, 12V DC car power cord, flexible air hose, Type-C charging cable, ball needle, Presta valve adapter, plastic inflatable nozzle, and user manual. The small adapters are stored with the unit, which helps prevent lost parts.
What is the most common mistake to avoid?
The most common mistake is using the wrong PSI target. For car tires, check your vehicle’s door placard before inflating, then set the pump to that number and let auto shut-off do its job.
The Bottom Line
The Eyshwu D04 Tire Inflator Portable Air Compressor earns a 7.8/10 because it gives you useful roadside protection in a compact, easy-to-store package. You should buy it if you want 150 PSI pressure, cordless use, 12V backup power, auto shut-off, and adapters for tires, bikes, balls, and inflatables.
You should look elsewhere if you need a quieter inflator, a longer hose, or a heavy-duty compressor for large tires and repeated full fills. For most drivers who want a glove-box-friendly emergency pump, the D04 makes a practical and credible case.
