You can connect various devices such as smartphones, cameras, keyboards, and more to computers to transfer data, or plug into wall chargers to charge these gadgets with a Type-A port. The longer answer is that the age of your device plays an important role, dictating both how fast it can be charged, and whether it can be charged using a wall charger at all. Shortly thereafter, USB devices that implemented this spec started to arrive.
The $57 Aukey PA-Y13 46W USB-C Charger will charge even a top-end MacBook pro, though its 46-watt USB-C port won’t do it as fast as Apple’s 87-watt charger. But unlike Apple’s chargers, you can also plug in devices using regular and quick-charge USB-A ports. Apple’s 18-watt USB-C power adapter isn’t cheap at $29, and it’s bigger than newer third-party chargers that can deliver more power. But it’s a clean, solid adapter design that’s good for charging tablets, phones and other smaller devices. With Apple’s $19 USB-C to Lightning cable — also expensive — you can charge your iPhone or iPad fast, too. Barnes & Noble Nook Color devices also require a special charger that runs at 1.9 amperes.
“Micro-USB pinout and list of compatible smartphones and other devices”. This USB power meter additionally provides a charge readout and data logging. Prior to Power Delivery, mobile phone vendors used custom protocols to exceed the 7.5 W cap on USB-BCS. Up to 6 unit loads; with multi-lane devices, one unit load is 250 mA. Up to 6 unit loads; with SuperSpeed devices, one unit load is 150 mA. Up to 5 unit loads; with non-SuperSpeed devices, one unit load is 100 mA.
(See USB Battery Charging Specification, section 3.2.3.) The hardware test takes place before turning the data lines over to the USB transceiver, thus allowing a CDP to be detected before enumeration. On paper, the PD 4 marks off just about all of the checkboxes that one could want. However, there is no dedicated power button to turn the charger on or off. This means that you’ll need to unplug it from the wall if you want to turn the charger off. Also, there is no official Quick Charge 3.0 support, and PowerIQ will likely do the job, but we still would’ve liked to see QC 3.0 onboard. This design looks extremely clean and will blend in rather nicely sitting next to your iMac or MacBook Pro. However, there are no USB-C ports, and the LED indicator light cannot be turned on, so you’ll have to resort to unplugging the charger if the light is bothersome.
Modern laptops no longer need a big power brick — you can just use USB-C. If you’re looking for the best USB C charger, read on to see which of the tried and true devices below will charge best for you. You might think that all chargers are created equally, but nothing could be further from the truth. Wired explains that picking the right charger with the right amperage can mean the difference between getting your phone charged while you work versus waiting all day before you can unplug it. A new generation of chargers with Gallium Nitride semiconductors are way better than the power brick which came with your laptop.

Another way to tell a USB charging cable from a data transfer is to actually test the cable. Since the USB Implementers Forum does not have a standard, symbol, label, or icon to distinguish these cables, you actually have to use them to find out. Because the USB Implementers Forum doesn’t have any rule enforcing USB manufacturers to label or differentiate charge-only cables from data-transfer cables, it is almost impossible to tell them apart. However, there are still some proven ways to find out if a USB cable is charge-only or supports data transfer. All USB cables have the positive and negative wires but not all USB cables have the data exchange wires — this is why some cables only charges your smartphone. Lifepowr’s $25 USB-C cable, called “the Beast,”is wrapped in a stainless steel housing for durability. It handles both high-speed data transfer — USB 3.1 at up to 10Gbps — and high-power charging but costs $32. I was terrified its flexing coils would catch an arm hair and give it a painful pluck, but I didn’t have any problems.

Make some article about using a 5V USB plug to extend laptop battery life. the older12v to 5v regulators are usually shunt based these can fail to a short and get the full 14.2 volts to the device you are trying to charge. Also any advise how to get the gauge back to initial state. With 2.1A, would it pumping in too much current to the battery. I got some questions, I am building a USB loading station for 4 smartphones that is indirectly powered by a solar panel through a 12V lead battery. Maybe you have some devices that are using “A” or “B” or “AB” connections and they are not all the same. In 2008, USB 3.0 relieved the power shortage by upping the current to 900mA. This current ceiling was chosen to prevent the thin ground wire from interfering with high-speed data transfer when drawing a full load.
