Can I use a regular old power bank with my Nexus 6P?

I have a couple of 2600mAh power banks that I used with my old phone. They're Duracell units I got from Costco but I can't find a link online, sorry. My new phone uses USB-C to charge which apparently draws 3A; can I still use these old power banks with my fancy new device? [more inside]

Laptop charged, house lights flicker. What's going on?

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]

Do I need to park in my garage to charge an EV?

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.

USB Charging, Computer vs. Line: What's the difference?

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?

As an hourly contractor, what tasks should I charge for?

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]

Correct way to charge rechargeable devices (iPhone, laptop, toothbrush)?

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]

What should I bid to implement a fairly simple Python scheduling system?

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]

Why can't I charge my GoPro with a portable charger?

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?

Solar panel sucks power??

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]

Charging a RAZR phone via USB

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.

What are appropriate rates for computer surveillance work?

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.

iPhone Battery Charging

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?

Charging electronic devices overseas

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?
