Cordless Ratchet Head To Head Kimo Vs Aoben

Which Cordless Ratchet Should You Buy? AOBEN vs. KIMO

Thanks to modern technology, you don’t have to undergo the stress of manually fastening or loosening nuts and bolts anymore. Whether it’s for a vehicle repair, construction work, or a home project, a cordless ratchet will always come handy. It saves you the time and energy required to carry out your bolt-fixing work.

A ratchet is a popular tool in automatic mechanics and other related fields. If you find yourself twisting and turning a lot of bolts in your day to day tasks, a power wrench will improve your efficiency and suit you better than a manual wrench.

Even the air-powered ratchet has its limits when compared to the cordless or battery-powered variety. Air tools run only on a consistent supply of air from a compressor, whose air hose can be very noisy. There’s also the issue of maintenance, as you will need to oil it every other day.

On the other hand, the cordless tool uses a more convenient rechargeable battery. As long as you charge the battery, you can use it anywhere, even in tight nooks and crannies. So what else is there to look for in buying  Power Ratchet Wrenches?

The battery-powered ratchet is also cost-effective as you won’t need to invest in a compressor.

Features to Look Out For When Shopping For a Cordless Ratchet

There are many cordless tools in the market, and you might have a little difficulty purchasing the right one. However, there are features you could look out for before buying any.

#1 Portability

Portability is an essential consideration when shopping for a cordless electric wrench. If you need a ratchet you can carry about, maneuver into tight corners, or work with for several hours; you should choose a lighter tool. If it’s bulky, you might find it challenging to work in confined spaces like an engine room.

Size and weight vary by brand. The good news is that you can find several cordless tools that are small and compact. An acceptable length ranges from 12″ to 14″, and its weight shouldn’t be more than 3lbs. The aim of getting a light tool is to avoid fatigue.

#2 Torque

The torque is a measure of how much the force acting on an object will cause it to rotate. It’s vital because it determines the usefulness of the tool. The more the torque, the faster you can loosen or tighten a bolt. The torque output can range between 30 to 80 ft-lbs. However, you should understand your needs to get the electric ratchet that best suits them.

A higher torque is more appropriate if you’re working on massive bolts and nuts. Smaller bolts require lesser torque tools. If you’re okay with a slow device, you can also go with the lower option.

Even with selectable speed settings, some bolts and nuts need low torque, so they don’t break under pressure. Unless you’re working with very massive bolts and nuts, the lesser torque tools would likely suit your needs and save you money.

#3 Motor

A motor provides the power that the ratchet requires to function. It spins a set of gears to control the revolution or speed of the tool.

Several cordless products have a motor with a capacity of 12v. At this voltage, the ratchet’s speed ranges from 230 to 400RPM. For a voltage as high as 20v, you can get up to 800RPM.

#4 Battery

Some rechargeable ratchets have inferior batteries that make them unnecessarily heavy. They also take a long time to charge and a short time to last.

A cordless wrench with a lithium-ion battery will weigh less and last longer than other tools with batteries of the same size. The lithium-ion also recharges quickly and doesn’t have a memory effect. A lithium battery of 2000mAh can have a full charge in just 60 minutes.

Don’t settle for an older model with inferior battery capacity.

#5 Durability

A battery-powered wrench has complex components and moving parts that are subject to wear.

For instance, the gear drive can stop the tool from functioning when it’s faulty. Cordless tools with metal gear drives like steel, aluminum, or copper are more durable than rubber or plastic gears. Rubber gear drives are cheaper but more subject to breaking and wearing.

The metal gear drives may be more expensive, but they are better in the long run. They will resist impact from drops and falls, which may occur while working. They will also serve you for years with low maintenance costs.

#6 Drive Head Size

You may need to choose an appropriate drive head depending on the kind of work you do. For vehicle repair and home maintenance, both 1/4 inch and drives will work fine. If you’re a technician with heavy-duty jobs that need a higher torque, a 3/8 inch drive will perform better. It also comes with more socket options.

#7 Noise Levels

A battery-operated ratchet that produces unpleasant sound won’t be ideal. Look out for cordless power wrenches that won’t be a source of disturbance to you when working.

#8 Design

A comfortable grip is a vital feature to keep in mind when shopping for wrenches. Some ratchets come with anti-slip handles, which are preferable. They will stay firm in your hands for the duration of your work.

Cordless wrenches also come with a battery power indicator to inform you of your current battery level.

#9 Accessories

Buy a tool that comes with its battery and charger to save you the effort of looking for compatible accessories. Certain ratchets also come with a complete set of sockets.

Things like LED lighting and power indicator are helpful accessories to have. However, if your job involves tasks like engine maintenance, LED light may not be an essential accessory.

If a one-time purchase is vital to you, buy a ratchet kit that will save you the hassle of buying accessories separately.

Final Verdict: Which Cordless Ratchet Should You Buy?

Choosing which cordless ratchet to buy between the AOBEN and KIMO is a bit tricky. One tool performs better in power while the other is more pocket-friendly.

The AOBEN ratchet is more applicable for light use due to its low torque and motor speed. It has excellent design features, and it is more affordable to purchase. However, its weight of 5 pounds and a length of 12 inches make it too bulky to use.

I could buy the AOBEN to save costs, but I wouldn’t use it for long.

On the other hand, the KIMO ratchet has a maximum torque of 40 ft-lbs and a motor speed of up to 400RPM. With this feature, you could work on large bolts and select a speed setting that will work for smaller bolts. It’s also very light to carry with a weight of 1.7 pounds and a length of 11 inches.

Although the KIMO battery may not be sufficient for a long duration, it comes with two batteries. You can charge one while using the other. It’s also more expensive than AOBEN ratchet. However, it’s still cheaper than other brands with the same capacity.

Due to its lightweight and selectable light-to-heavy use, I’ll pick the KIMO cordless ratchet wrench over its AOBEN counterpart. I can work with it for a long time because its lightweight will minimize fatigue, and I can change the batteries. Besides, the KIMO cordless electric wrench allows me to work on a variety of materials.
