I've just moved into a new (to me) house. (The house itself is old and quite funky.) I brought with me my extant Macbook Pro (most-recent vintage). I'm finding that when my computer is fully charged and the charging cable is plugged in (green light), the house lights flicker. [more inside]

I will be doing about 4-5 weeks of camping in the mountains in West Virginia, Kentucky and Tennessee this Summer. I think I'm pretty well prepared, but I don't want to forget anything, and would love to hear your tips for what to bring, what to remember, etc. Extra bonus points for good recipes and tips on powering devices!

I've been thinking about buying a used EV - maybe a Nissan Leaf. I have a very small garage which I use for storage. There is power in there. 1) How much does it cost to install a charging station? 2) Can I park in my driveway and run a power cable to my car for charging? I'm talking about six or ten feet.
I'm trying to set up several micro USB charging stations in my house and car, and I'm realizing that I retain very little from 9th-grade Intro To Electronics. Set me straight on how current works? [more inside]
My wife's UP band quit working. When she called tech support, they told her that they had found that some of the devices would quit accepting a charge from the plug-in, and only accept a charge via the computer. She chuckled, but tried charging from the computer and it worked. Can anyone explain to me what's going on here?

I'm an independent developer. I work from home, and I charge most of my clients by the hour. Often, a project will require the computer to do something while I twiddle my thumbs; for instance, downloading, uploading, running, or compiling a lot of code. I'm divided as to whether to charge for this. [more inside]
More and more cell phones opting for waterproof construction (yay!), and each of them seem to be doing their own thing as far as waterproof connections. Is there any movement afoot to standardize these things as they become more widespread? [more inside]
I've just been told at the Apple store that it's a bad idea to keep the iPhone plugged into the power for long periods when fully charged, and that if possible I should really only charge it when it tells me to (ie. when the battery is almost dead). [more inside]
my galaxy s3's usb charging port is loose with every cord I have, and only works in certain positions, (and charges slowly even then) so I'm looking into alternatives, including Qi charging or repairing the port. Advice needed. [more inside]

Tomorrow morning I'm meeting with someone to talk about implementing a local scheduling/database application. Most everything I know about the project suggests it's something I could do in my sleep. Thing is, I desperately need the money, I don't know how much to "bid," and I have a long history of undervaluing my work. How much should I ask for? [more inside]

I have an imaxpower IMP880 portable charger. I would like to use it to power my GoPro Hero 2, but it doesn't work. The output on the device claims 5V/0.6A. Does the charge not output enough power? Should I simply look for a device that outputs 1A?
Explain to me the technology of charging devices. Is it mainly about voltage? About current? How close to the "required" values must you be? [more inside]

I have a mini solar-panel (it's about 2sf) and claims to good for about 75w. In full sunlight it outputs about 19v. Of course when the light fades, the output voltage drops. There doesn't seem to be any 'electronics' built in - it just the silicon panels and output wires (with a female car charger socket soldered on actually). I want to use it to charge a mobile phone and laptop. But ... what seems to happen (with the laptop) is that is actually drains the battery somehow. [more inside]

Is there any way to get a RAZR phone to reliably charge via USB on a Windows machine? I have a v3m and everything seems hit or miss, regardless of the cords or drivers I use. Since there's gazillions of these handsets still in use, I wonder if someone has discovered a solution.

I'm currently running a business where I monitor computers for people. I use custom made software that gets by all the anti-malware scanners and through the firewalls. I have been charging $40/hr for the first hour, and $45 for each hour after that. Since most of work may only take 1-4 hours per client I've been told that I'm charging too little. Figures have been thrown at me by friends, family and even clients that I should charge $60, $75 or even $100. What is a fair amount in this business. Yes this involves spying on people at the workplace, churches and spouses. My first question. I've searched mefi for similar stuff and came up empty.

We've all been reading about the iPhone and its battery that's supposed to last 300-400 charges. How do they define "charge"? I usually charge mine every night, when the battery is at about 50%. Is that a "charge"? If I top my iPhone off when it's at 80%, is that a charge? What's the best way to preserve the life of my iPhone battery?

I recently sold a photograph (of dragonflies copulating, no less) to an Italian publishing house. They asked me to send an invoice and appropriate tax information. This is the first time I've ever sold something like this; can anyone tell me what forms, et cetera I ought to use or make? Thank you!

I'm traveling outside of the U.S. (to Israel) and want to know about charging my electronics. I'm only taking a few (I agree with comments in a summer 2005 posting that taking too much stuff can distract from the actual visit) namely my HP handheld (for contact numbers) and my digital camera. I may need to recharge both. I have the original charging cords, appropriate adapters and I have access to a transformer. Do I use the transformer, and is it safe to charge these devices overseas?
