AOBEN Cordless Ratchet Wrench, 3/8 Inch 12V Ratchet Tool Set with 2 Packs of 2000mAh Lithium Ion Battery and Charger

電動のためエアーツールには劣るが問題なし、バッテリーも２個付属なのでバッテリー切れの心配もなし、普通に毎日使えてます 良い買い物をしたと思ってます。

I bought this after doing a review of all of the available motorized ratchets, to assess which might meet the needs of a weekend auto mechanic (hence the first person). I've used everything from Black and Decker to Makita to Milwaukee to Husky tools, as well as Harbor Freight, all of which have their pro's and con's. After looking extensively and trying out some of the various options from friends and the stores, I settled on the Aoben, based on cost, durability, the two batteries, and the 2000 mAh ratings (as well as the various reviews out there). When I got the kit, I tested the amount of charge on one of the batteries, assuming they'd be close to one another. The other one I put on the charger to see how long it would take to charge. Battery 1 was able to get through an afternoon of wrenching, pulling out various bolts from from the engine and transmission of an air cooled vehicle. I'd say I used it all told about a half hour, dropping it twice when reaching for some tight areas under the hood. (I used it outside of the motorized aspect as well - it's a 'regular' ratchet wrench as well). No issue with that. It still had charge, and when I put it on the charger it took about 35 minutes to fully charge. The smaller head was able to get into some cramped areas, which was greatly appreciated particularly when one can only 'feel' but not 'see' the nut. Battery 2 took about 48 minutes to charge (from red to green on the indicator), and the swap was fairly easy - it's a bit tight for the batteries, but only took a modicum of pulling to get it out. The functionality was no issue with both the tool and the metric sockets that came with the kit. I was also using my old hex attachments which were longer, and I didn't have any issues with those either. I did notice I scraped the plastic just above the battery when the tool got caught on the hood brace, but otherwise the two drops (from about waist height) didn't seem to cause any issue. Of note this is made in China - like virtually all of the other motorized ratchet wrenches I looked at (Makita and Kimo being the exceptions). At least for a weekend mechanic, the Aoben works well for what I need it for, and potentially even more than that. It isn't as heavy as some of the others, it's well balanced, and as noted, it can fit into some tight areas which others might not be able to do so. Although I wish the finish was a bit better (that plastic scrape was my fault, though), I'm otherwise pleased with the tool, the batteries, and the sockets. It's high value for the price.

Works fantastic. I've wanted one for a while, but the main Home Depot competitor is twice the money. Its also probably twice the tool, but if you are a do-it yourself shade tree mechanic, this is great value. I bought this and used it immediately on a complete rebuild of a 6 liter diesel engine, and this was the MVP tool for that entire job. Some reviews giving it bad review because it has no 'loosening' power, but none of these types of ratchets are, even the air driven ones aren't. They aren't designed to 'break' the initial connection. You put it on the bolt, pull on the body of it like a regular ratchet to crack the nut/bolt loose, then you press the button to spin it off with the motor. Manufacturers 'say' not to do it this way because people would attempt to use these in an improper method, like standing on the tool to get a bolt loose, or attach a pipe to it. They aren't designed for that and people are just dumb. It situations where its too tight to turn, you need a bigger tool like a breaker bar to loose the bolt. This will take it off the rest of the way! That battery lasts a really reasonable time. the build is pretty good. I feel the battery connects to the body in a little bit of a 'cheap' or not well executed design, i had the battery pop out a few times, but the price of this is 1/2 of the nearest competitor and so far its doing exactly what I need it to do. 6 month update: Still holding strong. This is now on my top favorite tool. I've used this on every engine work I've done in 2019 since I bought it. The battery each last a long time, but its quite a bit. The quality has held out so far, i've dropped it a few times and no issues. Worked on all kinds of engines with it, super happy.

Works well, torque is good. Trigger is variable speed but the top speed isn't super fast if that's what you're after. Solid for amateur use, a pro might want a high end tool - might. Batteries charged up fine and seem good. Battery cases are clipped shut not screwed and are a bit tricky to crack open if you want to replace the cells at some point but it's not terrible. Overall a decent tool for $60
