Usb Charger
The expectation is that integrated circuitry will be used for this, as with the MAX8895 in Figure 2, or that this circuitry will be included in the USB transceiver. Nevertheless, adding port detection, or at least some subset of it, to an existing charger may sometimes be preferred. Figure 4 shows circuitry for a rudimentary USB charger detection scheme that operates under control of the system microcontroller. This approach can detect a DCP, but cannot distinguish between an SDP and a CDP. It treats both as an SDP, which means that in some cases it can miss the opportunity to draw more charging current from a CDP. The MAX8895 charger self-enumerates with a USB source to optimally set charge current depending on the type of connected power source.
It delivers 30 watts of power, and its power prongs snap back for easier travel. At $19, it’s a notch cheaper and more powerful than Apple’s $29 competing model.

The device features 6 USB output ports that will definitely come in handy for those who have more than a couple of phones and other mobile devices that can be charged via USB. Another advantage to the multiple port USB chargers is their portability. Most are small and lightweight enough to carry in a briefcase or purse. If you are a large family with numerous electronic devices, a USB charger with multiple ports will make road trips much easier. Wall chargers connect to standard 120V electrical outlets to provide USB ports for charging devices. Some compact devices need high charge currents but cannot tolerate the excess heat that those charge rates would generate in a linear charger. In those situations the MAX8903 operates a 4MHz DC-DC converter that keeps the component footprint small while still delivering up to 2A to the battery from adapter sources.
You will need to solder one 150k ohm resistor to the data- pin/wire of port 1, as well as to the data+ pin/wire and also to both data pins/wires of port 2. Then you need to solder a 560k ohm resistor to both ground pins/wires and both 5V pins/wires. Then solder the other sides of all resistors connected to port one together, and do the same with port 2. If you’ve purchased a new, current phone over the past couple of years, chances are you were notified of quick charging when you first plugged it in with your unique charger. Your best bet, at least as far as Qualcomm’s Quick Charge goes, is to find Qualcomm-certified chargers. Chargers straight from your phone’s manufacturer should work, too. They’re often found at the bottom of our smartphones and tablets for charging up the battery. They’re also found on a myriad of other devices and hardware in the market.
Logicfest January 13, 2014 Remember when cell phones all had their own, strange proprietary plugs? Thank goodness most have changed to allow for both charging through standard USB ports and almost all use standard USB cables for recharging. Even Apple products use standard USB plugs for all their cables, albeit with odd, proprietary connectors. For example, let’s say you’re using an old 5V/1A charger on a brand-spanking-new smartphone. You’re going to have less than stellar results there, because it’s going to charge the device much more slowly than the charger that came with the phone. Does that mean you can’t use a 5V/2.1A charger, or even a 9V/2A charger (in the case of USB-C)?
Despite its advertised 40-watt maximum output, we measured 12-watt draw from all four ports at the same time, for about 48 W total. Based on our experience with the PowerPort 4, even if the speeds do drop a bit in practical use, you can still be sure of fast USB-A charging across all the ports. The Aukey Focus Duo 36W Dual-Port PD Charger (PA-D2) is what you should get if you want to take advantage of fast USB-C with multiple devices. When a single port is in use, it charges at up to 30 watts. This dual–USB-C setup is still pretty rare, and the PA-D2 offers the best execution of it. Be sure to allow yourself room to expand by purchasing a charger with more ports than you currently need. This will help you to maintain your goal of reducing clutter by using only one outlet when you expand your inventory of electronic devices that require charging.USB cables. Using a substandard USB cable can hinder full-power charging of your devices. Even though the cables that accompany smartphones are sufficient, some of the generic micro USB cables do not perform the job very well.
When some portable audio players are plugged into a USB port, they are designed to go into a data transfer mode as soon as the data connection is made. In this mode, the device cannot be used to playback music even if files are not actually being transferred. By plugging the USB charger in without pushing it all the way forward to the data pins, the cable can make contact with the power pins and recharge the device while leaving it in a mode that allows playback. has two ports that support Qualcomm’s Quick Charge 3.0 standard, clearly marked in orange. Another four ports go up to 2.4A with Aukey’s AiPower technology, so they’ll determine what rate to charge when you plug in your device.

Although Apple’s charger works just fine, you’ll probably want to consider a third-party wall charger for the regular iPhone 11 or an earlier model. The regular iPhone 11 and the iPhone SE only come with a 5W USB-A charger, which is woefully inadequate for getting your device charged up quickly. And the current rumor mill seems to indicate that the iPhone 12 may not even ship with a charger in the box at all. USB Power Delivery is a relatively new fast charge standard that was introduced by the USB Implementers Forum, the creators of the USB standard. It is an industry-standard open specification that provides high-speed charging with variable voltage up to 20V using intelligent device negotiation up to 5A at 100W. Some of them have USB-A ports that can deliver the same voltage, while others feature one fast (2.4A) and one slow . If the device and the charger port both support the USB 2.0 standard (pretty much the least common denominator these days for entry-level Android smartphones), you can charge it at 1.5A/5V. Some consumer electronics, such as higher-end vape batteries that use the Evolv DNA chipset, can charge at 2A. A USB 3.0/3.1 charge port on one of these batteries can supply 3.0A/5V — if the device supports it.
