Apple sells it as a standalone item, so you’ll probably want to buy a USB-C to Lightning cable if you don’t have one. I would be interested in a test of car USB chargers. iPhone oplader Wow, I would never have guessed how bad aftermarket solutions are. I just went home to meet the fire department that responded to a fire alarm in my home.
In my detailed disassembly of the iPhone charger, I looked at the inside of the iPhone charger. The iPhone charger uses two circuit boards that together form a one-inch cube, which is an impressive technique. IPhone and iPad chargers are flyback switching power supplies, but the feedback mechanisms are very different. In comparison, the transformer of the counterfeit charger is of much lower quality. (I didn’t add the images for space reasons; click to view them.) It simply has the polarization winding, secondary winding and primary winding, separated by electrical tape.
With a power of 12 watts, it will noticeably lag behind many of the other load-bearing stones on this list. The load-bearing brick is also less sturdy than the others on this list. If you’re someone who loses your bearing stones often or if you’re looking for a secondary load-bearing stone to travel with, this affordable option is a great option. If you have multiple smartphones competing for the chargers available in your home, consider buying a charging brick with two ports instead of multiple charging bricks with one port.
Kindle ended up narrowly outperforming the iPhone 5. Thanks to everyone who voted; Stay tuned for more disassembly. I bet it probably took a long time for him to buy the cost, evaluate all the different measurements, and present his findings.
For efficiency analysis, I use 12 cents/kilowatt-hour as a typical residential energy price, which I obtained from Table 5.3 of the U.S. Photo of PMP W loader used with permission from Texas Instruments. Samsung’s cube charger has a similar shape to Apple’s iPhone charger.
