Electric cars are designed to run by the use of a battery or 'electric' parts rather than from fuel like gasoline. Electric cars don't pollute like gasoline ones do so that makes them environmentally friendly. I believe in the future of electric cars. But there are some draw backs.
Let's look at a typical comparison to prove this point. A normal 9.6 volt cordless drill will weigh around 3-1/2 lbs and costs you $35-$150 a piece, depending on the model and brand you choose. If you opt for a higher voltage tool, a 19.2 volt cordless drill would weigh up to ten lbs and costs anywhere from $120-$300 a piece. If you are looking to get more power and torque from a cordless drill, then it may justify the cost of getting a more expensive version. But if you are merely looking to drive screws in your own home, then it would not be a wise move to waste your hard-earned money on a powerful 19.2 volt cordless drilling. It is much harder to use too because cobalt mines of the additional weight. Under these circumstances, a lighter version would suit you best.
The typical lithium-ion battery lasts 2-3 years. Eventually oxidation lowers internal resistance, causing it to not be able to deliver the stored energy, even though the battery is charge. Lower current draw applications will add to the life vs. high draw devices with cobalt based Li batteries, like laptops, cameras, and cell phones.
Another option is battery-powered gloves. The very best of these uses lithium-ion batteries that will keep you warm for hours and recharge rapidly. On the lower end are gloves that use regular AA batteries or something similar. These tend to be bulkier and do not last as long, especially the rechargeables. They do have the advantage that you can just swap in a fresh pair if the ones you're using run out of power. But your best bet is to carry a spare lithium ion batterty stocks-ion battery and do the same thing.
The Milwaukee 2410-22 Cordless Drill provides up to 35% faster speed than its competition. The powerful motor delivers 250 in/lbs of torque, which is 25% more than comparable models. It also has a life cycle of one full day before having to recharge. It's the only tool in its calls with a 100% metal 3/8" ratcheting and locking chuck for maximum grip on the bit. The Milwaukee drill offers a lightweight and compact size and an cobalt ontario copyright ergonomic handle for easy handling. The powerful M12 lithium-ion batteries deliver a fast, 30 minute recharge so your tools are ready when you need them.
You have more power to perform work better and faster such as drilling and screwing than the smaller model. Once I used the 18v model I found that I prefer to use it more often because it gives me more power to complete the same task with less effort. At the end of the day it is better and faster, productivity counts.
These scooters have ranges and speeds similar to the 2 wheel models above, with increased range for some models capable of carrying larger battery packs. As for cost, a few of the Zap models can be had for less than $1,000. The rest range on up to as much as $3,000 for a top of the line E-Bikeboard.
