Torque ratings on all those types of tools are complete BS. The method used to measure that peak torque has little relation to actual usage.
B&D is strictly a bottom-tier consumer brand. Fine for limited use, but don't expect much from any of their stuff. Most of the brands are owned by only a few conglomerates and they specifically differentiate between the brands by various quality modifications. So you do, generally, get what you pay for.
Cordless has its place, but you need the higher end stuff to deal with things like lug nuts. Any corded tool will work much better. Or, just get used to breaking the lugs loose manually then using whatever to spin them off. And as mentioned, do NOT use an impact to tighten the nuts. Get them close, then manually tighten. After much, much experimentation I know that my air gun, at marker "2" with 110PSI source, lands lugs nuts at about 70ftlbs, which gives me just the right amount of room to tighten down to ~80-90ftlbs with another 1/4-1/2 turn. But you need to know your tools and check and double check to do something like that.
The biggest thing with cordless is you're buying into a family. The batteries and chargers are so expensive (*) and wildly incompatible, so you really need to see what set of tools you might eventually want to use and buy that. Super frustrating because, e.g., I bought into the Makita 12V series. Loved 'em. Now totally discontinued.
(*) Again, you get what you pay for. The super cheap batteries on Amazon are cheap for a reason. They might work fine for a while, might catch fire, might have less than half the capacity on the sticker.
