johnnyonetime posted:serious Tools! question up in here. I don't own a single battery operated tool. I have a corded circular saw, drill, hammer drill, impact, blower, weedeater, etc. I have hand tools and sockets and several 100ft extension cords. I'm in my mid 30's, just never jumped on the battery powered tool bandwagon. I was admiring my brother's cordless tool collection over Thanksgiving trying to decide what system I wanted to invest in and had a crazy idea: Instead of buying the same tools in the battery format, what if I just dropped some cash on a Honda generator to power my corded tools? Aside from less mobility I can't really see much of a downside. I live in the mountains so the generator would see double duty when I go out camping/offroading. Plus in the next few years I plan on building a goon shack off-grid and feel like the generator would get a lot of usage out on the mountain. Is there any huge downside I'm overlooking? I'm sure I could buy a lot of nice battery tools for the cost of a high quality generator, but I'm a minimalist and don't want two of everything. Are the good brands making a lot of corded tools anymore? I imagine the used market for corded tools is pretty good. How terrible of an idea is this? AC corded tools have RPM advantages. DC battery tools have torque advantages. There's many instances where you'd prefer a DC battery tool even if electricity and the AC powered tool was free. Impact drivers for example. Plus even off the grid, would you prefer to keep a gen (or some other powered source) running all day while you are using the tools, or just run the power source every so often for a quick battery charge? I think most trades and construction have long abandoned AC tools with a gen and have switched to DC battery for good reasons. E: The only people running a gen these days are ones that need air or run a circular saw all day. On that note, If you want to still go with AC and a gen. try find quality s/h gear like you're thinking - metabo, hitachi, bosch pro Fo3 fucked around with this message at 17:21 on Nov 25, 2018 |

revmoo posted:That's unbelievable. As in I don't believe it. On the other hand, just because a wall outlet is capable of putting out say 15A, doesn't mean anything plugged into it will draw that much. Corded tools will have a label that says how much current it actually draws(though even then the numbers are often fudged by listing the peak inrush current which only happens for the first fraction of a second after turning on a tool and doesn't necessarily tell you something meaningful about the overall continuous power). Anyways, cordless vs corded maximum power pissing match doesn't matter all that much since most modern cordless tools from a decent brand have plenty of power for most tasks.

Lithium cells have really high values and are happy to dump a hundred amps or more of current. Check out the little cells you can buy for remote control cars, planes, quadcopters, etc. Like this little guy will happily provide 44 amps: https://www.batteriesplus.com/productdetails/RCV10173 It's why for a lot of these batteries and raw cells you charge them in a kevlar bag because if anything shorts them out they will dump hundreds of amps and explode or light on fire very quickly.

Rhyno posted:What's the best bang for the buck mini compressor for roadside tire inflations? I just noticed that Dewalt has one which looks pretty nice: https://www.dewalt.com/products/gear-and-equipment/air-compressors/20v-max-cordedcordless-air-inflator/dcc020ib It can run off either a 12V car outlet or a 20V Dewalt tool battery (someone mentioned a similar product from Milwaukee a while ago, but it only runs off a battery). And according to at least one online review, its auto-shutoff is way more accurate than most mini-compressors offering that feature. I'm thinking about getting one in the near future.

To stick with corded vs cordless chat, I've got a nice Milwaukee corded drill on the tool chest. It's literally been in the drawer for 2 years, because I've switched to using my Makita LXT brushless drill for everything. Never once have I thought "hey, maybe the Milwaukee would be better for this task". Modern lithium brushless tools are that good.

Yeah but 44 amps * 20 (18v but lets be generous) = 880watts You can pull 1800 watts from a 15a wall outlet.

Do tool manufacturers still lie and list the amp‐hours as if the batteries were in parallel but the voltage as though they are in series?

Platystemon posted:Do tool manufacturers still lie and list the amp‐hours as if the batteries were in parallel but the voltage as though they are in series? That depends entirely on the manufacturer but for most major tool manufacturers, no. Most 18650 cells are 3.7V (around 4V when charged hence being called 18 or 20V depending who's selling the battery pack with 5 in series), and they tend to be 1.5 Ah to 3 Ah depending on quality. My 4Ah 20V Ryobi battery has 10 3.7V cells in it, which is two sets of 5 series batteries that are in parallel so they are around 20V fully charged and they hope the cells are good for 2 Ah each which is a decent midrange 18650. The 1.6Ah battery packs are only 5 cells and they have to be lovely because they drain quickly. The blatant misrepresentation of amp hours I see most often is on ebay listings for 18650 cells where they'll claim each one is 3000 mAh or that four of them are 10 Ah because maybe they might be if they were run in parallel but they make it seem like each one is going to be 10 amp hours. For example: https://www.ebay.com/itm/18650-Batt...2pnwg:rk:9:pf:0 I'm sure each of those is 1500 mAh or less.

Might need to derate that further unless you've got one stout extension cord. Your instantaneous startup amp draw has to play nice with the breaker too. Platystemon posted:Do tool manufacturers still lie and list the amp‐hours as if the batteries were in parallel but the voltage as though they are in series? Not that I've seen. No way they could feasibly get away with that - the compact packs are all 1P anyway, so the 2-3Ah rating they get is what the cells themselves are rated for. The larger capacity packs are 2P or 3P.

1500w should be a piece of piss. Now go fantasize about the single phase 2400w heaters we have in socialist 240v* countries and shut up. * nominal, it'll do we're socialists... technically 240v +5 / -10, then officially 230V but don't tell anyone because some person with actual 250V will complain their appliances might not last as long or whatever  Main thing is though: DC - more manageable and usable torque. The fact that you people don't have 10A/240v makes a stronger case for not bothering about corded power tools IMO. Fo3 fucked around with this message at 18:17 on Nov 26, 2018 |

I'm reading reviews, people seem to have nice things to say about the shop-vac brand. Filters and accessory prices don't seem unreasonable. Edit: I own a Menards "Workforce" drill and impact set I got 5-6 years ago. It's held up pretty well, batteries hold charge well enough. Is the workforce stuff a rebrand?

The best thing about my rigid shop vac is that it’s way quieter than other shop vacs I’ve used. It’s one with their scroll noise reduction. Not sure if other modern shop vacs have similar noise levels but it’s really my favorite thing about it.

Avoid Stanley shop vacs, at least the cheap one Costco sells or used to sell. It's total trash and loses suction instantly.

Also avoid the one with the motor that pops off to become a leaf blower. And don't let the filter come off the mount a bit, so all the dust goes into the motor. The bearings will start howling after a few minutes. I use a Dust Deputy on a 5 gallon bucket, which then goes to the shop vac (the leaf blower one, its not great but not bad enough to replace). The shop vac has a hepa filter main filter, and I buy the bags. Drywall dust ends up settling a bit in the bucket, then the bag ends up with a bit, and the Hepa filter remains mostly clean. The bucket also catches the large derbis so the bag doesn't fill up too often.
