I have to ask why on God's green earth would you subject yourself to that? And just because you have it and it still works is not the right answer.
I'm not certain I understand the question completely. I always have a small generator with me or a way of produce 110VAC power. Not always do I have a compressed air supply. Nor do I at this time have a battery operated impact wrench in 1/2" drive but do carry a general tool set with me. I carry the impact behind the seat in the pickup, (Krusty Dodge) along with a mechanical scissor jack and these get used often changing tires as I hate spinning lug wrenches any longer.
In reality I don't need the latest and greatest. Only need and keep what works. That impact and jack have changed literally a couple dozen tires alongside the highway bordering my shop. It also rattled better than half the fasteners holding my shop together all those years ago.
Only cordless tools I have are a Milwaukee screwgun for drywall, a Milwaukee grease gun sharing the same battery, a couple of DeWalt drills that are beyond worn out, and a Harbor Freight 1/4" hex drive impact my son bought me as a joke after I was ripping on their tools. I must admit that HF tool has held up well and readily snaps drive bits. I have also been very impressed with the Milwaukee stuff as far as ergonomics and power.
In reality I will continue to build upon the Milwaukee base as some of the stuff is impressive. I would like to have both a 1/2" and 3/4" impact in the brand.
Much of my corded tools are either Milwaukee, or Black & Decker Industrial line of tools. Both circular saws are DeWalt and have electrical dynamic braking to the spinning blade and stop very shortly after releasing the trigger. None of these are the "homeowner" line of tools; hence the reason they are still around. On that manlift I ran a 14/3 SOOW cord up the boom in with the hydraulic hose routing terminating into weatherproof receptacle box mounted to the basket back wall. It is almost as JLG would have supplied the option. With the small RV generator strapped to the hood and this cord plugged in, there is no loose or bitter end to be concerned with. Most times from my understanding an extension cord is not used in the basket as cord on the tool is long enough to reach. Again, I've not used it myself.
Thanks for asking.
