Not All USB Power Is Created Equal

jfruh writes "We've reached a point in our electronic lives where most of our gadgets draw power from a USB cable, and we have lots of USB ports to choose from — some of which live on other gadgets, some of which live on adapters that plug into your wall or car. But those ports supply wildly varying amounts of power, which can result in hours of difference in how long it takes your phone to charge. The Practical Meter, the product of a successful Kickstarter campaign, can help you figure out which power sources are going to juice up your gadgets the fastest."

Indeed they do. If the charger says "I can supply 1.5A" but due to thin wires in the long, cheap cable that results in a significant voltage drop the device backs down to a lower level.

This is why I build my own USB leads using #00 welding cable.

business plan generator for 2013:

1. browse dx, find a neat product, that seems practical while being utterly useless for your usual hipster, preferably with nice lights.
2. ask around your hipster friends if they've heard of such a product. if they have go back to 1.
3. if not, then track down the manufacturer industry guy from china.
4. put the fucking thing on kickstarter with reduced features to put down cost(come on, going from a segment display to fucking FOur FUckING LEDS!!).
5. have them dropship the product from said china guys warehouse
6. you're in the moneeeyy you're in the moneeeeyyyy.
