Can You Use Any Charger With Any Device?

USB-C chargers are turning up on many different devices, so it’s not strictly relegated to laptops. Newer phones use USB-C charging, car chargers may come with USB-C ports, and portable chargers can have USB-C options. But laptops tend to have USB-C more frequently than other devices, at least for now. Ultimately, it’s really the amperage that determines how fast a charger will supply power to your device. If you want quicker charging, look for a wall or car charger that delivers 2100 mA of current at 5 volts (or whatever voltage the device you’re trying to charge is specced at). If you want to simultaneously charge two phones at the fastest speeds possible, or to take advantage of Apple’s MagSafe Charger in your car, we recommend the Scosche PowerVolt PD40. It’s one of the most affordable dual–USB-C car chargers you can get from an accessory maker we trust, and unlike cheaper options, it stays snugly in place to ensure your phone continues charging. Each port supports 20-watt charging speeds, even when you use them at the same time, and the device overall is about the same size as the tiny Nekteck 45-watt charger but not much more expensive. The Nekteck PD 45W Type-C Car Charger is the right model for any vehicle, any phone, and almost any device you might want to charge while driving. It’s a tiny but powerful charger that has both USB-C and USB-A ports, ensuring near-universal charging compatibility.

It is advised to only use compatible or trustworthy brands when experimenting with higher voltages and currents in USB connectors. New devices come with the USB-C connector and USB 3.1, but consumers beg for two or three regular USB 3.0 ports on their gadgets to support what worked so well in the past. USB 3.1 is backward compatible with USB 2.0 and USB 3.0 and the classic type-A and type-B connectors. While in transition to the type-C, adaptors are available to convert, but expect lower data transfer speeds with adapters than what USB 3.1 offers. As with most other successful technologies, USB has spawned several versions of connectors and cables over the years. USB chargers do not always work as advertised and charge times are slow.

This device allows you to use a single power outlet for one transformer and provides power to four or more USB ports. Different types of USB charging stations are available, so you will want to be sure to research features offered when considering a purchase. Are there chargers that can charge multiple devices at once? Some mains USB chargers have up to three USB ports built in to the plug. There are even chargers that are designed to charge two or more brands of phone at once. A wide variety of cellphone chargers and cradles are available for many different types of phones and many uses. Phone chargers exist for your home, car, or for use on the go. From the traditional corded car charger to the portable and efficient solar charger, there is a charger or cradle for every cellphone. Car chargers – A typical car charger is a corded device that plugs into the 12-volt DC adapter or cigarette lighter in your car. This type of charger draws power from your cars battery if the car is turned off, or from the cars alternator if the car is turned on, providing a reliable way to charge your smartphone on the go.

An increasing number of devices rely on USB chargers to draw power. Cell phones, tablets and game console controllers all connect and charge via USB connections. While it is likely that you have a collection of cables and USB plugs in a drawer, grabbing the closest charger might not be your best option. A group of electronics manufacturers introduced the technology in a bid to replace standards, including PS/2, Parallel and DB9 Serial connections. Today, there are various USB variants in use, which means that you first need to ensure that you choose the right standard from a selection that includes USB-A, USB-B, USB Type-C™, and both micro and mini versions. Furthermore, some USB chargers offer faster charging, thanks to a higher voltage or thicker lead, and some act as a hub, providing charging and connection for multiple devices. A power adapter that generates the 5 volt DC standard required by USB. The charger plugs into an AC outlet, and a USB cable plugs into the charger. USB ports on computers have an upper limit of 500 milliamps; however, USB chargers that come with cellphones and other devices handle one or more amps. The devices sense when they are connected to a computer versus the charger and regulate their current draw.

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.

With the right multiple USB port charger, you will know that all of your important devices are well protected. Multiple USB port chargers are compatible with a wide range of devices. From smartphones to tablets and from Android to Apple, USB chargers with multiple ports will charge nearly any device with USB connection capabilities. The most obvious advantage to a multiple USB port charger is that you can charge multiple devices at one time. These chargers accommodate anywhere from two to ten devices. Even those that work with four or more devices are often lightweight and do not sacrifice portability. Un-powered USB chargers draw their power directly from your computer. These are not recommended if you need to charge multiple devices.

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)?

It can also withstand, as well as block, inputs up to 28V. This protects the battery, the charger, and downstream circuitry against inadvertent connection to almost any known adapter type. In addition, the MAX8844 includes overvoltage-protected LDOs, biased from the USB and adapter inputs, that can supply 30mA to the system. These LDO outputs remain on whether or not the charger is enabled. In Figure 6 simple Li+ charging functionality is added to a USB device. The MAX8814 can be configured to charge a battery from either 100mA or 500mA USB ports. The microprocessor then enumerates the host to determine its current capability. If the USB port is capable, the charging current is increased by turning on N1 and R1 in the current-setting network. The high-level charge is nominally set to 425mA to avoid exceeding the SDP 500mA limit after tolerances are considered.

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.

It comes in a cloth bag to cut down on the banging and scratching during travel, but the bag covers up the LED status lights on the outside. A bit bigger than a 9-volt battery, the $21 Chargerito is the smallest USB-C charger I’ve found — it even comes with a keychain loop. It plugs into the wall with flip-out power prongs and another flip-out USB-C connector, so you don’t need a cord — which, let’s face it, is often the bulkiest part of bringing a charger with you. You have to be comfortable perching your phone on the wall, though. I found it plenty sturdy, but don’t put it in the hallway where you or your dog might bang into it. Due to their versatility, usb wall charger can be designed to be configured explicitly for each vehicle platform. They take up minimal space while still maximizing the power supply. Also, they are efficient as they are made to optimize charge current and reduce charge time.

We also looked for models that were built to withstand extreme conditions so you can climb any mountain in any weather without ever having to worry about your charger being damaged by the elements. With its foldable lightweight design, this unit is great for backpacking. It weighs only 20.6oz and measures 11.1” x 6.3” x 1.3” when folded. It comes with four carabiner clips and can easily be attached to your backpack or tent for solar power wherever you are. You can usually find information about your equipment’s wattage requirements from the manufacturer’s documentation or the equipment nameplate. (If the power requirements are listed in amps, multiply by the input voltage to find the wattage.) For assistance with UPS sizing, contact our application specialists at or + . Hot-Swap PDUs have dual input power cables to enable live-replacement of select UPS systems with no power interruption to connected equipment. Digital Load Meter is a local display on metered, monitored, switched and ATS power distribution units that reports output power consumption in amps in order to facilitate load balancing and avoid overloads.
