Compact 150W switched-mode power supply (SMPS) in 4”x2” package

However, unless very carefully designed and using suitable components, switching adapters are more likely to fail than the older type, due in part to complex circuitry and the use of semiconductors. Unless designed well, these adapters may be easily damaged by overloads, even transient ones, which can come from lightning, brief mains overvoltage (sometimes caused by an incandescent light on the same power circuit failing).

The European Union defined a Common external power supply for “hand-held data-enabled mobile phones” (smartphones) sold from 2010, intended to replace the many incompatible proprietary power supplies and eliminate waste by reducing the total number of supplies manufactured. Conformant supplies deliver 5 VDC via a micro-USB connector, with preferred input voltage handled ranging from 90 to 264 VAC.

He moaned and arched his back as my red painted lips got closer to his hard cock. As presumed, it was no monster, but definitely of length and girth that he should be proud. I put his cock in my mouth and he grabbed my hair gently. If we had had more time or if I intended to keep him, I might have instructed him to pull a bit harder and to reach over and smack my ass as well. I gave his hot, hard cock a few bobs.

As I picked up my morning coffee, I scoped out the place for possible prey. A new cock to suck from a suitable guy was on my breakfast menu. I made eye contact with a good-looking 30-something but quickly realized that he was a former conquest. As he approached to say hello, I raised my hand like a traffic cop and shook my head no. He stopped and retreated, obviously disappointed. I was looking for some fresh meat.

A survey of consumers showed widespread dissatisfaction with the cost, inconvenience, and wastefulness of the profusion of power adapters used by electronic devices. Science fiction author and satirist Douglas Adams wrote an essay bemoaning the profusion and confusion of power adapters, and calling for more standardization.

I led him to my car. We got in. As I slowly backed out of the spot, the 30-something guy walked passed, smiled and gave me a small wave. I drove to a quiet parking lot a few blocks away that I am VERY familiar with. There was no small talk. I parked. We unbuckled our seat belts and I moved our seats all the way back. I leaned over, grabbed his cock through his pants. It was clear that the pump didn’t need.
