Whether you’re looking for a small, portable charger or a big desk-friendly model, I’ve tested them all and these are the best multiport USB wall chargers available today. Looking to charge your tablet, cell phone, or camera on the road? Gearmo’s 45W USB car charger supports two USB Type-A ports and one USB-C port for charging new Type-C enabled devices. Find USB chargers and multi device charging stations for powering mobile devices of all types. Use wall chargers and other USB charging stations to charge your iPad, iPhone, tablets, smart phones, or cameras at home, office, or even in an airport for convenient and efficient charging. If the output voltage is not filtered well, there will be noise and spikes due to the high-frequency switching. At extreme levels this could damage your phone, but the most common symptom is the touchscreen doesn’t work while the charger is plugged in.
The size, shape, price, and environmental mission are otherwise respectable, but for sheer power-per-dollar, stick with our pick. Apple’s 20W USB-C Power Adapter is larger than Anker and Aukey’s 20W chargers, costs more, and doesn’t have folding prongs. We don’t see any reason to choose it over the models we recommend. The PA-D2 measures about 2.5 by 2.3 by 1.1 inches, meaning it’s small enough for you to carry it in a bag or purse without your really noticing it’s there. Its ports are stacked horizontally on the face opposite the folding prongs. The RP-PC132 is the smallest dual-port USB-A and USB-C charger we’ve tested, and in our tests it performed exactly as promised. You can expect an iPhone XS to charge to about 35% in a half hour on the USB-A port and closer to 50% on the USB-C port. Aukey’s one-port charger offers full-speed charging at an affordable price.
7-Port USB 3.0 Hub for Charging and Data connectivity, USBGear’s USBG-BREC307 is a USB 3.0 7-Port Hub that mountable to any flat secure surface. The hub’s USB 3.0 Super-Speed for streaming information or other data allows for fast data transfer. If you are purchasing a USB cable online, and the product page doesn’t explicitly state that the cable supports data exchange, the best bet is to contact the website’s customer support for confirmation. If you’re purchasing the cable in an offline store, be sure to meet the store attendant to confirm that the cable you’re buying is indeed a data cable. Because the majority of the USB cables being sold and shipped with smartphone support data transfer, you might have been wired to believe that all cables support data transfer.

The USB-C port on iPad Pro connects to external displays so that you can watch video, play Keynote presentations, and more on a larger screen. Depending on the display that you’re connecting to, you might need an adapter. You can connect iPad Pro to your Mac or PC to charge the device orsync content using iTunes. For example, the Nintendo Switch power supply provides 2.6A at 15V, which isn’t one of the profiles in this answer. Qualcomm Quick Charge 3.0 brings it one step further and now allow to “negotiate” any voltage from 3.7V to 20V by increment of 200mV. It seems that additional profiles have been added by some manufacturers, for instance, Qualcomm Quick Charge 2.0 seems to be an implementation of the Power Delivery but using 9V too. This technology though does not use the Power Delivery specification as it uses the D+/D- lines of the USB 2.0 port to negotiate the voltage. All in all, I guess that the laptops will as well charge with 5V , just far slower. And based on what I saw from Apple for their new Macbook, the charger is 29W, so most likely a Profile 3 , it seems then to be only 12V.
The power converter side of things can plug into US, UK, European, Australian and many other countries’ wall sockets, and you can likewise stick an equally broad range of plugs into it. If the adapter draws too much power, it’s got a circuit breaker that’ll trip and a one-touch button to reset it immediately. Another big USB-C benefit is that more powerful devices, like a laptop, can charge smaller ones like a smartphone, giving you a juice boost to bail you out when you can’t find a power plug. USB Power Delivery, or USB PD as it is commonly known, is a standard that allows devices to draw out the required power to charge it. This universal approach means a wide range of gadgets, including smartphones, tablets, and laptops, will be able to share adapters, chargers, and wires for charging. Internally a charger is an amazingly compact switching power supply that efficiently converts line AC into 5 volt DC output. The DC is chopped up tens of thousands of times a second and fed into a tiny flyback transformer. The output of the transformer is converted to low-voltage DC, filtered, and provided as the 5 volt output through the USB port.
The key reason behind this love is the materials used and the durability and safety offered by them. My mistake was using Apple’s slightly older 29W USB-C power adapter, which looks exactly like Apple’s more recent 30W USB-C power adapter. We’ve had that adapter plugged into our kitchen island for years, and it’s never before mattered. Unless you exclusively wish to charge Apple products in your car, there may not be enough features and cross platform compatibility to recommend this as an everyday charger. Of course, if you do only wish to charge Apple products, this is a winner. Not only is it a two pack, but it also has a total price of about 15 bucks, making this a really good value. Even if it isn’t, this device is still kicking out excellent power levels so it can be relied upon to charge just about anything. The all-metal construction, in addition to looking great, also allows for superior heat dissipation too – a design choice that is a nod to the incredible power that will be flowing through this bad boy.
Following one reviewers tactic, I used a blunt tool to exert more pressure on the button. As a “bonus”, the button stayed down in a lopsided sort of way, but now, I can rotate the prongs at will. I plan to update this review after used the device in its intended purpose. This section may stray from the topic of the articleinto the topic of another article, AC adapter. To recharge an electric vehicle battery pack; see Charging station. Some larger power banks have DC connector for higher power demands such as laptop computers. “smart” batteries with internal protection or supervision or management circuitry. If you appear closely, you will see that a USB socket has four pins.
Typically a PC has 500mA as the max amperage of a wall charger varies from one device to a different. Although, here is the case, the amperage of wall chargers is generally between .5A and 2.1A. The smart power management circuit design with over current and over-charge protection keeps your devices safe while providing optimal changing capabilities. The Flight Gear Dual USB Quick Charger is perfectly suited to keep all of your devices topped off. Two USB ports provide up to 6.0 amps (3.0 amps each), giving it plenty of power for even the newest tablets. I bought this years ago and find it’s a huge help when I travel or even when I want to plug in my laptop anywhere around my house. The best was after we lost power with Hurricane Sandy and I went to a coffee shop in another town to power my laptop and phone. All the plugs were taken but I had this little Belkin with me – so those using a nearby outlet were happy to share it and one woman I ran into later said she went out and bought herself one.
Then you connect the battery, and it will trickle charge and you can keep it connected forever. So…I’m thinking…using the 21 watt panel…plug in a usb to alligator clip connector to the 12 Volt 8 ah battery to trickle charge it. I’ve done a few solar installations in my RV and have a spare 21 watt solar panel with USB out for charging small devices. i have a 12 volt k-cell sealed lead, rechargeable battery that is dead and i would like to make a charger for it. or possibly might have one but i have no idea what im looking for. I’m looking at buying an mp3 player but I won’t often have access to a computer to charge the mp3 via a computer USB.
The demand for portable chargers is an overriding trend in the USB charger market, as customers are increasingly seeking portable chargers to replenish their smartphone batteries. Customer preference for retractable USB chargers to serve devices with different interfaces is also on an upswing, as consumers are willing to invest in multi-purpose USB chargers with exceptional compatibility. Unparalleled ease of usage will continue to be at the top of the customer priority list, and this is also likely to encourage suppliers to focus more on design optimization. I’ve seen micro-USB to USB-C adapters out there that may make charging QC 3.0 compatible devices possible with USB-C chargers, but will this result in nearly the same charging rates? I cannot say for sure since Qualcomm has always stated that BOTH device and charger need to be QC 3.0 compatible (each needing the additional Qualcomm hardware necessary for QC 3.0 charging). I do not have a QC 3.0 device nor do I have a USB-C device to test this out. It’s no secret that I love my Qualcomm Quick Charge 2.0 chargers because of how quickly they charge my QC 2.0 devices. I’ve been going along in my little QC 2.0 world and was quite content with the simple knowledge of which chargers to buy to take advantage of this fast charging technology. However, since Qualcomm Quick Charge 3.0 chargers/devices and the new USB Type-C fast chargers/devices are showing up on the market, I decided to investigate a little more about fast charging technology. Many of these are high quality even if they are not USB-IF certified.
(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.
If you are looking for a no-frills charger that won’t take up a bunch of space, then the Key Power Station may be the best fit. The SIIG Charging Station is perfect for those with a slew of devices, as there are slots for anything and ambient light. Satechi makes some of the most premium accessories on the market, and this 7-port charging station is no different. Velcro straps are included, so your array of cables don’t end up too unruly while keeping your desk space clutter-free. Additionally, each slot is large enough to accommodate even the largest smartphones and any cases you may have installed. We’re guessing that all other ports may start giving way to the USB-C. USB-C ports will soon outweigh all other ports in importance, taking over as the primary port. In the future, USB4 and Thunderbolt will likely be the standard.
