Electric Muscle Massagers vs Battery Powered Vibrators

Electric vibrating massagers and battery powered massagers are very often used to massage and stimulate aching and hardened muscles to get relief from the pain caused by them. However these vibrating massagers have become to be identified as sex toys over a period of time. The performance of the electric vibrating massager is better then the battery powered vibrating massager. Electric vibrating massager is considered more powerful than the battery powered vibrating massager for obvious reasons. The motor used in an electric vibrating massager is bigger then the motor used in a battery powered vibrating massager. The electric powered vibrating massager was initially produced to perform the larger body and muscle message and marketed as such, but people soon found other use of them and were labeled as sex toys. Nevertheless the manufacturers still market them as muscle massagers. The electric vibrating massager is very popular as a sex toy than a body and muscle massager. It uses an alternating current source as its power supply whereas the battery powered vibrating massager uses AA batteries which are much smaller and give out less power than an alternating current source.

The other advantage of the electric powered vibrating massager is that the head of the vibrator is connected directly to the electric motor which is not the case with battery powered vibrating massager. There is an indirect transfer of power in the battery vibrator resulting in a slight loss of power as compared to the electric vibrator. This results in stronger vibrations from an electric vibrator.

The sensations caused by an electric powered vibrating massager are much more powerful and intense than that of a battery powered vibrating massager. These powerful vibrations produce intense sensations which most of the people are unable to withstand especially women who use a padding to absorb part of the vibrations and reduce the intense sensations. If you are not comfortable with the vibrations they can be minimized as per your body acceptance level by getting attachments along with the vibrator made of soft material like silica, jelly or rubber.

The disadvantage with an electric powered vibrating massager is that it is not portable as the battery powered vibrating massager is. Once the electric powered vibrating massager is fixed in to a socket moving it to another location is difficult as the socket in another location may not be at the desired location or it may not be there at all.

Though there are a number of manufacturers of electric vibrating massagers but Hitachi, Wahi and Acuvibe electric vibrating massagers are the most popular ones in the market. The quality of the electric vibrating massager has to be of top quality as they have to act both as body and muscle massagers. Low quality vibrators also available in the market but then you are at peril of owning them. It is but natural that high quality electric vibrators will be little more expensive than the low quality electric vibrators.

Battery Powered Chainsaws

battery powered chainsaws are fairly rare in the United States, but if you are interested in a battery powered chainsaw you can find them. It may take some digging to do. There is one brand currently being offered that claims a single chain blade can cut 4,000 pieces of PVC pipe with only a small amount of oil required.

This saw has a chain tip guard to prevent kickback and extend chain life. The electric brake stops within ½ second of releasing the trigger. It also has hand guards. A hex wrench allows for rapid blade changes and adjustments.

The chain guard allows fast entry to the blade and motor housing area. The 12 V.N1-MH battery gives you a longer operating time. You can buy an optional handle if you will need a longer reach. This 4.6 pound dynamo cuts through a variety of PVC piping diameters.

We found two other brands of battery powered chainsaws. One made in China has a 12 volt battery and a shock absorption system. The other brand has an 18 volt battery and a 10 inch chain. There is little information currently available on these saws and most of what is available is anecdotal.

On one message board we found a discussion thread on cordless battery operated chainsaws. One participant said he made 12 cuts and took down a five inch sugar maple.
Another said he got one and it wouldn't cut a two inch twig - he had the chain on backwards. Overall it looks like the ideal chainsaw for the occasional user who wants to do some light pruning or to take down small trees.

AC Versus DC Powered Battery Back-Up Systems

Power outage can be a common occurrence during a severe rain storm. The sump system in a home typically relies on a heavy duty AC primary pump to discharge water entering the home through its drainage system. To compensate for the possibility of a power outage, the sump pit may include a battery-operated DC or AC driven pump in addition to the primary pump. How do these AC/DC pumps differ in function and performance?

A DC based back up system typically consists of a DC pump, a 12 volt deep cycle battery (2 batteries if a 24 volt system), and a charger. Most DC pumps used as part of a back-up system were initially designed to be bilge pumps for boats and are not heavy duty, but some work well. A characteristic of a DC system versus an AC system is that the rate that it discharges is related to the degree that the battery power source is charged. A fully charged 12 volt battery will power the DC pump to its maximum capability. As the charge of the battery is consumed, the pumping rate of the DC pump diminishes. For example, a given pump will discharge at the rate of 30 gallons per minute with a fully charged battery, but may only be pumping at 15 gallons per minute when half of the charge is still left with the battery. At the end when the battery is about to be depleted, the pump may be discharging at less than five gallons per minute. DC systems efficiently consume DC current and can run continuously for several hours (up to 10 hours continuously and intermittently for several days).

An AC based back-up system typically consists of an AC heavy duty pump, a 12 volt deep cycle battery (or two batteries if a 24 volt system), and an inverter with a battery charger). An inverter converts the DC power of the battery to its AC counterpart. Unlike a DC pump, an AC pump will run close to its maximum potential capability until the battery charge is depleted. For example, if the AC pump can pump at a rate of 50 gallons per minute, it will continue at close to this rate (with minimal loss over time) until the battery power source is depleted. It is important to select an AC pump with efficient amperage rating (3-7 amp hours), otherwise the system will not run long enough before the battery source is depleted and the system shuts down. An efficient AC pump can discharge as much as the best DC system because it is discharging at a greater rate than most DC systems even though it shuts down faster than a good DC pump system. The key advantage of going with an AC system is that it is easier to match it up with its primary pump counterpart. Since the AC system requires an inverter, it is typically more expensive than DC systems which do not require an expensive inverter for its operation.

The best way to compare different available systems is to compare the total amount of gallons discharged with a given battery (beginning with a fully charged battery recommended by the manufacturer) and that the data, ideally determined by an independent testing agency, represents the time and performance until the system shuts down). The values should have been generated at an 8-10 ft. head. The head is the distance that the pump discharges vertically (in a basement, it is usually 8-10 ft).

For the most part, A DC system will discharge at a rate less than the primary pump can discharge. Whether this is good enough is something that the homeowner and/or contractor must make a judgment call on. An AC system can be matched more effectively to the performance of the primary pump. The best scenario is that the homeowner has determined how effectively his primary pump has performed during a major storm and matches that performance with that of the back-up system, whether it be an AC or a DC system.
