DEWALT DC840KA 12-Volt 1/2-Inch Cordless XRP Impact Wrench Kit Review

Average Reviews:

(More customer reviews)After reading other people review the 12v seem like a good idea. Small, compact, lightweight, and supposedly enough torque to break lug nuts with ease. Well 1st attempt on my car seems good but i did not torque it to tight maybe 50 ft/lbs.
My brother car (06 STI) I know for sure it was torque at 65 ft/lbs because I was there when the mechanic torque it. It loosen the lug nuts but the impact was struggling real bad. It took about four or five fully depressed until it loosen. One can argue that it might be seize but the wheel was put on only for one week.
It is a good impact wrench for other lower torque rating bolts when working on the car.
I regret not getting the 18v. And would highly recommend everyone to consider the 18v rather than the 12v.

Yamaha EF1000iS 1,000 Watt 50cc OHV 4-Stroke Gas Powered Portable Inverter Generator (CARB Compliant) Review

Average Reviews:

(More customer reviews)I've used these with friends camping and been absolutely amazed. This model has a number of positives about it. Yamaha has produced small, reliable generators for over 15 years.
My big plusses:
1 - REALLY quiet. The engine drives basically just an alternator and produces about 12V, though it varries. When there is a small load on the generator (typical of most camping / outdoor uses) it slows down the engine. This not only makes it quiet, it cuts back on fumes, and saves gas. A tank filling can last half a day easily depending on demand.
2 - clean power. Because the alternator is outputting a DC voltage into a sinewave inverter your 110 VAC is comming from one of the best sources. I use inverters in many of my service vehicles, right at 1000W, and have found no situation where that was not enough power. Since the inverter tells the throttle how much power it needs, wasted noise and gas are eliminated. Basically it does not feel like the old 5000W genset on wheels.
3 - light weight. Compared to taking the 5000W generator camping, the small size and light weight are a welcome change.
4 - very small gasoline consumption. Unless you are running the full 1000W all the time you'll get great mileage. If you do need to run 1000W all the time, consider a larger digital inverter genset. Honda makes a 2000W which can be joined to a second 2000W for 4000 total if I recall.
5 - well built engine. Although only 50cc, it has overhead valves and excellent sound isolation.
Cons:
It's not going to run EVERYTHING in your RV at the same time. If you are watching the plasma TV (400W) and turn on the microwave (1000W) the generator will shut down due to the 1400W load. Consider your loads and if you must run everything simultaneously.
Heavy loads make it spin faster and thus change the acoustic tone of the exhaust. If it's within hearing range and you turn alot of stuff on/off the noise may irritate some people.
Pros:
Put a 100 foot extension cord between you and the generator and you'll be saying "what generator" as the lights and appliances work fine for 12+ hours. It's that quiet.
1000W is enough to run your vehicle's battery charger, a good size TV, and small cooking appliances, just not at the same time. Consider the kill-a-watt wattmeter to know EXACTLY what your load is P3 International P4460 Kill A Watt EZ Electricity Usage Monitor
