No more do you need lots of different chargers for lots of different devices (goodbye, Micro-USB!). If you’re on the go, you can move your laptop charging cable over to your phone and back to keep both devices’ batteries topped up. Today, USB ports are used for more than just data transfers and storage. USB connections can charge devices with most mobile chargers coming equipped with a single port USB charger that plugs into an AC wall outlet. USB chargers with multiple ports simplify life without putting a huge dent in your wallet. They differ from USB hubs in that they do not allow for data transfers from your devices to your computer. The best ones are powered – meaning that they plug directly into an external power source, such as a wall outlet. While this may look like a relatively simple and boring category, there’s actually some interesting innovation going on right now when it comes to charging standards. Charging from USB can take many forms, governed by the unique requirements of each USB device.

With online retail emerging as a force to reckon with across emerging economies, USB charger brands are concentrating on different ways to expand their online presence while becoming more agile and responsive. Analyzing the market progression and unceasing growth, Transparency Market Research estimates the USB charger market revenue to cross US$ 30 Bn in 2019. Mustak Ahmed – Would you be willing to rephrase your question and provide a little more information? For instance, do you have a USB-C Android phone or a micro-USB phone and what are you using to charge it ? An update on the Hyperjuice; I don’t use it very frequently (it’s my backup from my Surface Pro when I’m away from my work and home docks), but it seems to do the job well. I’ve even had it charging my Surface Pro and my Dell Latitude at the same time . For a start, they lack the 15V alt-mode required for compliance. A larger wattage charger must do everything a lower wattage charger will. That means if it has 20V then the 15V mode must be presence.

The classic USB plug that we are all familiar with, the Type-A USB is the larger standard rectangular plug. The types of USB refers to the physical shape of the plug. It is waterproof, shockproof, and dustproof, so it can go anywhere you go.

The Anker PowerPort 4 offers four USB-A ports in a compact design, making it ideal for a couple who’s traveling . It’s what I personally carry when my wife and I are on the go, as it allows us to charge our iPhones and Apple Watches from a single outlet. But if you have an iPhone with MagSafe and want to take advantage of the magnetic-charging feature, which lets you use your phone while it’s charging, we recommend RAVPower’s Magnetic Wireless Charger (RP-WC012). plugs in sideways can be a little awkward depending on the outlet, and you’ll find charging speeds are slower when using all four USB ports at once because the total output is limited. is relatively compact considering the number of ports, but it’s also quite light. However, since the power cord plugs into the back, it limits your placement options a bit. If we had to say anything negative, it does have a really bright blue light that illuminates when it’s plugged in, even when you’re not using the USB ports — so, it’s not one for the nightstand. There are no frills here, just six USB-A ports offering 2.4A each, up to 12A in total for a maximum output of 60W.

There are also plenty of USB chargers that don’t fit into this specification, such as AC adapters. Second, and this is a big one—helping customers or prospects out of a bind goes a long way. We’ve all felt the onset of a slight panic upon finding ourselves low on battery and without a charger. Be the hero and eliminate this issue by handing out custom portable phone chargers. First, let us state that the use of cellphones and electronic devices is so popular that it’s rare to find a person who doesn’t use one. This makes personalized phone chargers an easy and effective way to get your company’s logo and information in front of people every day. No matter which of your devices you are recharging, choosing solar power is better for the environment and better for your budget. Solar chargers come in a variety of sizes and styles and are designed to hold up to even the craziest of your adventures. This may seem a bit obvious, but the first thing you need to consider is the amount of power you’re going to need on average.

If you have a Quick Charge 3.0 device, definitely get a Quick Charge 3.0 battery. But if you have a Quick Charge 4.0 device or an iOS device, get at USB PD battery for now. Do it all with WORX Power Share™ – the only cordless tool platform that uses the same battery to power 20V and 40V tools. USB adapter attaches onto any 20V Worx Power Share battery. Beware of jealous friends that may try to steal you totally awesome charger. You might want to use a serial circuit so I suggest using a battery holder from an old remote or anything that uses batteries so that all the wiring is connected for you inside the battery holder. When your phone isn’t charging, then you have done it wrong. Put your battery holder connected to your female USB in the Altoids tin. Make the ON/OFF switch to the battery holder is up so that when you open the tin you see it the female USB port not stick out of the USB port, but have it line up so it doesn’t stick out.

When users buy our independently chosen editorial selections,we may earn commissions to help fund the Wiki. A different device might not be designed to communicate with USB or does not want to devote system software to manage USB charging. It just wants to use available USB ports as a power source. This approach can be used to avoid complexity or in response to worries that a software bug might cause incorrect charging. Since the system does not enumerate, the best charging option is a self-enumerating charger IC. The charger takes care of port detection and selects the appropriate USB load current limit without requiring help from the system .

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.

The great thing about solar power banks is that you can charge the power bank throughout the day and then use that to charge your phone at night or on rainy days when there isn’t enough sun. The only downside is that the electricity from the solar panels has to go through the battery before going to your phone. This means that if you let the battery run out completely, you will not be able to charge your phone until you have given the battery time to recharge. Why spend money on a device that can only be used one way when you can choose a device with versatility? That’s why we chose chargers that you would be able to use every day. You can take them on long hiking trips or simply use them at home to take advantage of free solar power, whatever works for you. The high-efficiency solar panels are designed to be water and dust-proof and the ports are protected by a waterproof cover.

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.
