UPS or surge protector for iMac

[umbilical]

hi again, what about this simple and small: http://www.amazon.com/Belkin-3-Outl...1520_1_20?s=pc&ie=UTF8&qid=1403568386&sr=1-20

note: that mini JUST!!! for 2 macbook's that I have, for the 3rd macbook that I have I go to buy an UPS, why? becasue around the 3rd I have other things like external hard drive, mac airport extreme, speakers etc... so yes for that I buy an UPS but for other 2 macbooks that are standalone I think a surge protector is enought, so that mini is enought?

thanks!

As posted,

Be wary of any recommendation that did not say why with numbers.

Did you read spec numbers for that Belkin? It will absorb 306 joules and never more than 612 joules. How does it block or absorb destructive surges that may be hundreds of thousands of joules? How will its 2 centimeter internal part stop what three miles of sky could not? Did you think it does something useful only because it has a name: "surge protector"? Where are numbers?

What anomaly are you trying to avert? Protect from a surge? Then why use a 'surge protector' that does not claim such protection. Why not use a 'surge protector' that is a completely different device and actually does protect from destructive surges?

A previous post discussed two completely different devices called 'surge protectors'. Defined one, for about $1 per appliance, that actually does protection. And the other (ie that Belkin) that only claims to protect from tiny surges that typically cause no damage.

Read its specification numbers. Where is one number that claims effective protection?

Same applies to that UPS. Specifically which anomaly is to be protected from?

wow! your reply is so technical to me I dont know anything about it... Im more confused now, so what I need buy to protect my macbook pro 13?

please suggestions with amazon links?

thanks

I use that belkin for 2 years, until now my macbook is fine. Although I'm not sure if it really protected my macbook from surges.

You already have it. Its inside the macbook.

None of this is technical. Discussed are layman's numbers If a protector is adjacent to a mac, then it must 1) absorb or 2) block a surge. View layman simple numbers.

Absorb: Belkin claims to absorb hundreds of joules. A mac, like all electronics, makes such tiny surges irrelevant. A surge that maight overwhelm and blow through a Belkin (ie 800 joules) would not harm the mac. In fact, the mac would convert that into electricity to power its semiconductors.

Block: how does that 2 centimeter part block what three miles of sky could not stop? It doesn't. They need you to not know what centimeters and miles are.

A scam is easy to promote. They tell you what to buy, never say why, and avoid all numbers. So yes, a majority may recommend the Belkin. And that will make you confused. Separate heasay from knowledge. Eliminate all posts that avoid numbers. What is left is useful answers and no confusion.

Did you know macs, like all electronics, already have internal protection? To hype fear, a Belkin is promoted without mentioning existing internal protection. To keep you confused and fearful, they do not discuss existing internal protection.

And finally, a concern exists for a surge that might occur once every seven years. Only that might overwhelm protection inside your mac, refrigerator, dimmer switches, air conditioner, dishwasher, clocks, GFCIs, and recharging mobile phones. Only a completely different device, called a 'whole house' protector, can avert that damage. This device works by being distant from electronics and low impedance (ie 'less than 3 meters) connected to earth. But you are not going to rewire their building. Either they already have this device proven by over 100 years of science and experience. Or you hope a surge that only occurs once every seven years does not happen. Nothing adjacent to your mac claims to protect from that rare anomaly.

That Belkin has one useful function. It is a USB charger.

so in conclusion I dont need nathing? just plug to the wall and that is?

just one thing off topic but related:
"if I plug in my living room... I feel electricity static around the trackpad" but "if I plug in my bedroom dont feel any static"... I think my bedroom have a better system electricity inside the wall...

Static electricity is charges created between your body and other charges in the floor. Touch electronics, and a discharge out the body and finger, through electronics, to floor via table legs or some other path, then connects to charges beneath your shoes.

Static is eliminated by connecting your wrist to those charged beneath shoes. Often by a conductor not considered conductive to 120 VAC electricity but very conductive to static electric. Pink poly plastic is one classic example. Wrist straps contain a large resistor (ie 1 Megohm).

Not generating those charges (ie a different rug, replace nylon fabrics with cotton, etc) is also useful. Increasing room humidity to at least 40% also helps.

However I suspect you have assumed static electricity rather than some other problem. If you do not move your feet, then a static charge would not build up. Static discharges are infequent and surprising. Other electrical anomalies have different symptoms.

Agreed, that's not "static electricity" but suggests a possible problem with your house wiring or outlet in the living room. Especially if you tried the 3-prong cord and still have the trouble. I'd suggest having a qualified electrician take a look at the outlet and wiring.

thanks very clear for static electricity.

but so about buy a surge protector or ups... so I dont waste my money? and dont buy anything? westom seems to say that...
I just need plug a macbook pro... I dont need plug router or hard disk... etc...

Ok lets say that you don't use a surge protector or ups.

And one day the unthinkable happens and your macbook fries.

How mad are you going to be at yourself?

I do consulting for a very large Alarm/Burglar company.

People and business buy millions of fire alarms and sprinklers hoping they never have to use them.

 

[deeddawg]

Kashsystems: I think you missed the point that westom was making.

To use your fire alarm / sprinkler analogy, would you recommend (for a building already with an adequate alarm/sprinkler system) a second alarm that was no louder than a whisper or a second sprinkler system that sprayed no more than a gallon per hour?

(In case you missed it, umbilical resurrected a four year old thread ask a question about a Macbook Pro -- which already has a built in UPS and surge protection in the power adapter.)

I think the cheap surge protectors are worthless.

On the built in surge protection, I also believe in redundancy. I rather have a go between device than use one is built into the pc.

Bingo.

As for redundancy -- yes, I agree, but only where the cost of redundancy makes sense vis-a-vis the risk-weighted exposure. You wouldn't put a $1,000 alarm system on your tool shed containing $100 worth of old rusty tools.
