Why do the kittens chew my cell phone charger?
Comments (20)Calliope, I think you might be on to something. They chew only the charger cord and always right where the wire goes into the charger thingy that apparently has current in at all times. But it's also true that months ago when they were really tiny, they chewed a very thin wire. Well, the FOURTH charger for this month is safely tucked away in a drawer and I'll start trying a couple of the methods you've all given me to try and make sure it's the last charger....See MoreCheap Cell phone Plan
Comments (39)There's many different Verizon coverages. Well actually, the same is true with all providers. Verizon cut back their area significantly for all accounts activated after February. For example, there's America's Choice version 1 & 2, InPulse, etc. And for some reason, the prepaid is always a more restricted coverage. They don't want to give the tightwads the same coverage as the more profitable areas, I guess. Probably think they'll hook people with prepaid and then opt for the postpaid to increase coverage. Doubt that'll happen. So far it doesn't seem to be happening either. And interesting too since the prepaid market is where their future is for adding customers since the postpaid market is virtually saturated and people can't change too often because of the cancellation fees in the contracts. It's irritating, but that's the way it is. The coverage map for PagePlus shows essentially the Twin Cities metro area is covered and St. Louis County in northern MN. Technically the rest of the state has "coverage", however, it's at the $1.99/min roaming rate. Way too rich for my blood! I don't mind some roaming charges for traveling since I don't use the phone much, but I'm not about to spend $2/min. Additionally you have to tack on the cost of a decent tri-band phone and PagePlus is out of my budget. SimpleFreedom has cheaper (about 50¢/min) roaming but they're discontinuing a lot of their service with no credit back to the customer. They have the option to sign up with another carrier. So I wouldn't mess with them at this point. At least without more research. Although the Sprint PCS coverage isn't great around here, I'm finding that it's not all that bad compared to the others. At least they cover the major freeways and some highways where PP, Cingular and others don't. And I do tend to stay on the major highways. And since I like the phone I got for Virgin, I might just hang on to it. But I'm still tempted to try out USA1rate and see if their coverage is what they claim. The prepaid coverage leader overall would have to be TracFone, unless the maps are accurate for USA1, but TracFone's rates are pretty high unless you play games with transferring back and forth between a couple of phones and/or beg people to sign up to get referrals. I can justify what I'm spending for a phone. Could justify a bit more to have better coverage even at roaming rates. But I'm not crazy. Argh! I've been looking around again. Head's spinning again. Why don't I simply slam my hand in the car door? Be more enjoyable than trying to interpret their websites!...See Morespeaking of phones--Land line? Cell? Both?
Comments (45)I misplace my TV remote enough that I don't want to be looking for my one and only phone. I have a 10 room two story house and wouldn't even hear the phone unless it was strapped on my body. I have three phones downstairs and they are always on their stands when not in use. The cell is in the car because I always forgot to bring it in the house. It's not a smart phone,( we opted for an iPad instead) just a flip top Samsung and we 're not on a program. We "buy" minutes every year and it's pretty cheap. Our phones are part of our Verizon bundle... My son has only a cell phone, no land lines and kept his old number....See MoreAnother cell phone question
Comments (12)If you want to talk about power flow through batteries and electrical devices, I'll put it separate so as not to confuse the above. You're right - draw and pull aren't really the right words to use. They're colloquialisms I've used for years in my job. "This pulls 10 amps," etc. The best analogy, and the one that was often used in my education, is to liken the flow of electricity to that of water in a pipe. A higher amp circuit is a bigger pipe. A higher voltage circuit is like a pipe with higher water pressure. The current-using device is like the faucet you open or close. Higher pressure (voltage) and lower resistance (Ohms) are what will increase the current (amps) through the circuit. Amps do not exist until current begins flowing. Amperage ratings of power delivery equipment refer to the maximum allowable amperage the circuit or device can safely carry. Amperage ratings of power consuming equipment refer to the maximum amperage they'll carry in normal operation. To relate that to this discussion, it should now be clear why a higher amperage charger is fine: it's merely a bigger pipe that can deliver more current if needed. That doesn't mean the current will flow - the voltage and resistance will determine that - but that it can flow if needed, exactly as I started in my analogy of the night light and the microwave oven. Charging batteries is an interesting area, because you can observe what happens with a device called a Kill-a-Watt that indicates the wattage used by any device you plug into it. I have a 12-volt car battery that is one of those "booster" batteries you can use to jump-start your car if there's no other car around. You charge this battery with a supplied plug-in charger. If the battery is heavily discharged, the charging wattage will show about 14, but as the battery nears a full charge, the wattage slowly drops to about 2, and at that point you can unplug the charger. This happens because as the charger continues to supply a constant voltage, the charging current drops as the battery's internal voltage nears that of what the charger is delivering. This all occurs not as a function of any type of computerized circuitry in the charger, nor as a result of the charger's maximum amp rating, but simply because of how current flows in the battery charging process. "Smart" chargers can affect the charge rate of a battery by applying different voltages at different phases of the charging process, as batteries of different chemistry do better with faster, slower charges or other specific things, such as high voltage early and low voltage late in the charge, or whatever. Most cell phones today have charge control circuitry to somewhat counter the detrimental effects of constant overcharging, as people frequently do when they charge the phone all night while it's still turned on and they're asleep....See Morepetrushka (7b)
