Milwaukee M12 Tire Inflator and Its Alternatives

Milwaukee is known among cordless tool users for two battery families: the compact M12 (12-volt) line and the larger, more powerful M18 (18-volt) line. Its tire inflators follow the same split, and they are popular because the batteries already sitting in many garages and work trucks can power them, so there is no cord to plug into the car and no separate charger to keep track of. For a first-time buyer or someone picking a gift, the two questions that matter are simple: does the person already own Milwaukee batteries, and which size?
The four options below differ in battery system (M12 or M18), in whether a battery comes in the box, and in one case in who makes the tool: the DIYtoolifz model is a third-party inflator designed to fit Milwaukee 18V batteries, not a Milwaukee product.
Milwaukee Tire Inflators Compared
| Model | Battery system | Battery included | Max pressure | Hose length |
|---|---|---|---|---|
| M12 Compact Inflator 2475-20 | M12 (12V) | No, tool only | 120 PSI | 26 inches |
| M12 Compact Inflator Kit | M12 (12V) | Yes, 4.0Ah plus charger | 120 PSI | 26 inches |
| DIYtoolifz 150PSI (third-party) | Milwaukee 18V compatible | No, bare tool | 150 PSI | Not listed |
| M18 Inflator 2848-20 | M18 (18V) | No, tool only | 150 PSI | 36 inches |
Two quick definitions help here. PSI (pounds per square inch) is the unit tire pressure is measured in; most car tires need somewhere in the 30s, so a 120 or 150 PSI maximum simply means plenty of headroom. “Tool only” or “bare tool” means the box contains the inflator but no battery and no charger, which is ideal if you already own the right batteries and frustrating if you do not.

Milwaukee Electric Tools 2475-20 M12 Compact
Best for: Existing M12 battery owners
Pros
- TrueFill auto shut-off
- Tops off car tires under 1 minute
- Illuminated digital gauge
- Reinforced cage
Cons
- Tool only, no battery
- Airflow figure listed inconsistently
The Milwaukee Electric Tools 2475-20 M12 Compact inflator is the classic M12 tire inflator, sold tool only. Milwaukee says it tops off a car tire from 28 to 35 PSI in under 1 minute and fills a light truck tire from 30 to 45 PSI in under 4 minutes, with a high-efficiency pump and motor rated for true 120 PSI capability.
Its most useful feature for beginners is TrueFill auto shut-off, part of what Milwaukee calls REDLINK intelligence. You set the target pressure on the illuminated digital gauge, which shows both target and current readings, and the inflator stops when it gets there, while also protecting against over-temperature and over-filling. The listing gives gauge accuracy of plus or minus 3%, a 26 inch hose, a 50% duty cycle (meaning it should rest roughly as long as it runs during heavy use) and a weather- and impact-resistant reinforced cage. It measures 6.5 by 6.5 by 7.5 inches and weighs 3.5 pounds. The listing is messy on airflow: the feature text gives 0.88 CFM at 0 PSI and 0.63 CFM at 35 PSI, while the spec table shows “63 cfm,” which looks like a missing decimal point, and the voltage field reads 220 even though it runs on 12V M12 batteries.
This is the right pick for anyone who already owns M12 batteries and a charger. If they do not, the kit version below saves a second purchase.

Milwaukee M12 12-Volt Lithium-Ion Cordless Compact
Best for: Gift-givers and first M12 owners
Pros
- 0Ah battery and charger included
- TrueFill auto shut-off
- 120 PSI rating
- 26 inch hose
Cons
- Listing gives few feature details
- 12V is slower than M18 for big tires
The Milwaukee M12 12-Volt Lithium-Ion Cordless Compact inflator kit pairs the M12 compact inflator with a 4.0Ah battery and a charger, according to its listing title. That makes it the only complete, ready-to-use package in this guide, and the easiest gift for someone who has never owned a Milwaukee tool.
The description matches the tool-only version: it is rated to deliver 120 PSI, tops off car tires in under 1 minute, handles car, light truck and compact equipment tires, and uses TrueFill auto shut-off that senses the speed of fill to stop precisely at the desired pressure. The listing specs confirm a 26 inch hose, automatic operation and the M12 connector. The item weight is given as 2.79 kg, and the listing does not say whether that includes the battery. It has fewer feature bullets than the tool-only listing, so details such as gauge accuracy are not restated here.
A 4.0Ah battery is a mid-size M12 pack, so it should cover several top-offs between charges, although the listing does not give a run time. Choose this kit if the person is starting fresh.

DIYtoolifz 150PSI Tire Inflator Compatible with Milwaukee 18V for Preset Modes

DIYtoolifz 150PSI Tire Inflator Compatible
Best for: Milwaukee 18V owners wanting preset modes
Pros
- 150 PSI max pressure
- Five preset modes with auto shut-off
- LED light with SOS mode
- Four nozzle attachments
Cons
- Third-party, not made by Milwaukee
- Battery not included
The DIYtoolifz 150PSI Tire Inflator Compatible model is honest-to-label third-party: it is made by DIYtoolifz and designed to run on Milwaukee 18V lithium-ion batteries. Milwaukee does not make it, and no battery is included. We include it because many people searching for a tire inflator for a Milwaukee battery own M18 packs and want an alternative with more convenience features.
The listing gives a 150 PSI maximum, a large metal cylinder delivering 28 liters per minute of airflow, and says it inflates a 195/65/R15 tire fully in under 4 minutes. An LCD display shows pressure and offers five selectable modes with preset pressure and automatic shut-off. It adds an LED light with a white mode and red flashing SOS modes, a low-battery alert, four nozzle attachments for balls and toys, and a noise figure of 58 dB. At 2.8 by 5.6 by 8.1 inches it is compact enough for a glove box or under a seat. The listing does not specify hose length or weight.
It suits someone who already owns Milwaukee 18V batteries, wants preset modes for bikes, balls and car tires, and is comfortable buying from a non-Milwaukee brand. If you prefer to stay with the original maker, the M18 2848-20 below is the Milwaukee-built 18V choice. For another budget-friendly portable format, see our portable air compressor review.

Milwaukee M18 Inflator 2848-20
Best for: Light truck and larger tire owners
Pros
- Tops off 33 inch truck tires under 1 minute
- 150 PSI max pressure
- 36 inch hose
- Brass Schrader and Presta chucks included
Cons
- Heavier at 7.7 pounds
- Tool only, M18 battery needed
The Milwaukee M18 Inflator 2848-20 is Milwaukee’s larger 18V inflator. Its listing calls it the fastest 18V cordless tire inflator and says it tops off 33 inch light truck tires in under 1 minute. It is optimized for passenger, light truck and other medium-duty tires, with a 150 PSI maximum pressure.
It comes with a useful set of accessories: an all-brass Schrader chuck (the standard car tire valve), an inflation needle for balls, an inflator nozzle and a Presta chuck for road bike valves. The hose is 36 inches, ten inches longer than the M12 models, which makes reaching valves on bigger wheels easier. It weighs 7.7 pounds and measures 14.7 by 7 by 8.3 inches, so it is noticeably larger than the M12 version. The spec table lists the operation mode as manual, and the listing does not mention auto shut-off, so do not assume it has the same TrueFill feature as the M12 models. It is tool only and needs an M18 battery.
Choose it for pickups, SUVs, trailers or anyone who already runs M18 tools. For a small car and occasional top-offs, the lighter M12 versions are easier to store.
How to Choose the Right Milwaukee Tire Inflator
M12 vs M18. M12 tools are smaller and lighter; M18 tools are bigger and built for heavier work. The M12 inflators handle car and light truck tires, while the M18 2848-20 is aimed at light truck and medium-duty tires and adds a longer hose. Pick the platform the person already owns, because batteries are not interchangeable between M12 and M18.
Tool only or kit. Only the M12 Compact Inflator Kit includes a battery and charger. The 2475-20, the M18 2848-20 and the DIYtoolifz are bare tools.
Auto shut-off. The M12 models list TrueFill auto shut-off, and the DIYtoolifz lists preset auto shut-off. The M18 listing does not mention it, so plan to watch the gauge.
Brand preference. If you want everything from Milwaukee, skip the DIYtoolifz. If you are open to third-party tools that share your batteries, it adds modes and a light. Readers on another battery platform can compare our portable tire inflator roundup.
