Battery Life

The Durofix RI12184-4PG G12 impact wrench comes with two lithium-ion battery packs - a 4.0Ah and a 2.0Ah. This gives you flexibility for longer or shorter runtimes.

The larger 4.0Ah battery provides exceptional runtime. On a single charge, you can expect to get up to 260 bolts driven per charge. That's enough power to complete most automotive or construction jobs without needing to stop to recharge. The rapid charger replenishes the 4.0Ah battery in around 60 minutes.

When you need a more compact and lightweight setup, the 2.0Ah battery pack is a great option. It provides up to 130 bolts driven per charge. Recharging takes around 30 minutes with the rapid charger. This makes it easy to top up the charge between tasks.

Both battery packs feature a fuel gauge that shows the remaining charge level. This helps avoid unexpectedly running out of juice mid-job. The batteries are also compatible with other Durofix 12V max tools, making them versatile for projects that require both drilling/driving and impact wrench capabilities.

Overall, the battery options provide a great balance of extended runtime and convenient recharging. Whether you opt for the long-lasting 4.0Ah or nimble 2.0Ah, you can tackle projects with confidence.

Accessories

The Durofix RI12184-4PG G12 impact wrench kit comes with several handy accessories.

Batteries

It includes two lithium-ion battery packs - a 4.0Ah 12V battery and a 2.0Ah 12V battery. Having two battery packs allows you to keep working without delays. When one battery runs low, you can simply swap in the fresh one. The larger 4.0Ah battery provides extended runtime for bigger jobs. While the compact 2.0Ah battery is great for lighter tasks. Both batteries use the 12V G12 system, providing sufficient power for the brushless motor.

Charger

To keep the batteries juiced up, Durofix includes a compatible G12 smart charger in the kit. It can charge one or both batteries at the same time. The charger shuts off automatically when the batteries are fully charged, preventing overcharging. It's a simple plug-in charger, so you don't have to take the battery packs off the tool to charge them.

Carrying Case

The kit also contains a heavy-duty canvas carrying bag. The bag has a padded handle and shoulder strap for easy transport. There are dedicated pockets and slots to hold the tool, batteries, and charger neatly in place. This makes it convenient to transport everything to and from the job site. The case provides protection for the impact wrench kit during storage and transportation.

Ease of Use

The Durofix RI12184-4PG impact wrench is designed to be very user-friendly. The controls are intuitive and easy to operate even for first-time users.

The forward/reverse selector switch makes it simple to change directions. Just flip the switch to change from tightening to loosening bolts.

Weighing only 2.2 lbs, the RI12184-4PG is lightweight and easy to maneuver. The soft grip handle enhances comfort and control during extended use. For convenience, an integrated LED light illuminates your work area.

Overall, the Durofix impact wrench is designed for maximum ease of use even for DIYers. The intuitive controls, quick bit changes, low vibration, and lightweight design make this tool a pleasure to operate.

Noise

The Durofix RI12184-4PG G12 impact wrench operates at a sound level of 85 dBa under load, which is slightly quieter than comparable brushed motor impact wrenches but on par with other brushless models. Its brushless motor design helps reduce noise and vibration versus standard brushed motors.

When running no-load, the tool has a sound rating of only 80 dBa. This is quiet for an impact wrench, allowing extended use without hearing protection in some cases. However, hearing protection is still recommended for prolonged use under load, when the tool operates at its peak 85 dBa rating. This is a common sound level for 1/2" drive impact wrenches.

Overall, the Durofix G12 ranks among the quieter impact wrenches in its class. While not the absolute quietest, it offers a noticeable noise reduction over cheaper brushed motor models. The lower noise makes the tool better suited for automotive and home garage use where sound levels are a concern.

Pros

The Durofix RI12184-4PG G12 impact wrench has several notable pros worth mentioning:

Compact Size

One of the standout features of this impact wrench is its compact and lightweight size. Weighing only 1.4kg, it's one of the smallest and lightest 12V impact wrenches on the market. The stubby design allows you to fit it into tight spaces that a regular impact wrench wouldn't be able to reach. This makes it ideal for automotive work where you often need to get into cramped engine bays. The small size doesn't compromise on power either.

Good Power

Despite its small stature, the Durofix RI12184-4PG G12 delivers impressive torque power. It provides 300Nm of maximum torque, which is enough for most automotive repair and maintenance tasks. The brushless motor provides strong fastening and loosening capability without overheating. You'll have all the power needed for lug nuts, brake caliper bolts, suspension components, and more.

Battery Life

With the included 2Ah and 4Ah batteries, you get excellent runtime before needing to recharge. The 4Ah battery in particular can deliver up to 265 bolts per charge. The batteries use G12 lithium-ion technology for long battery life and steady power delivery. Having two battery packs allows you to always have one charging while the other is in use. This improves workflow and minimizes downtime.

Cons

The Durofix RI12184-4PG G12 impact wrench has a few drawbacks to consider:

Price - This tool has a higher price point compared to some other 12V impact wrenches on the market. The kit with two batteries and a charger retails for around £150, which may be more than some buyers want to spend. The bare tool alone costs over £100. So while the Durofix offers good power and performance, it comes at a premium price.

Lack of Torque Control - There is no variable speed trigger or torque control settings on this impact wrench. It operates at essentially one speed and power level. This makes precision work a bit challenging, as you can't easily dial back the torque when needed. Some users may prefer an impact with more control.

Availability - Durofix power tools are not as widely available as brands like DeWalt or Milwaukee. So sourcing this specific model may require shopping online versus picking it up at a local hardware store. Limited local availability could be an inconvenience for some buyers.
