Included safety features help detect and deliver surge protection and temperature control. As this speedier cable becomes more popular, you may run into issues where you have a USB-C cord and a USB-A port without any way to connect them. When that happens, a USB-C adapter can help bridge the gap. If you travel regularly, you will know how quickly your phone or tablet can run out of power. These specially crafted devices let you use your car’s battery to efficiently charge up your mobile in no time. In contrast, laptops require adapters and batteries that can output at a higher wattage. Most modern cell phones, laptop and tablet computers, and most electric vehicles use Lithium-ion batteries. When stored after charging, lithium battery cells degrade more while fully charged than if they are only 40-50% charged. As with all battery types, degradation also occurs faster at higher temperatures. Degradation in lithium-ion batteries is caused by an increased internal battery resistance often due to cell oxidation.
There was a time when every device seemed to come with its own unique charger. Remembering to pack the right charging cable was a must if you wanted to continue using your device whilst away from home. However, the Micro USB has combatted the industry’s use of custom ports and now charging your phone on-the-go is no longer a problem with the standardised connector. The 30000mAh lithium-ion battery can hold enough power to charge your phone up to eight times on a single charge. It also has a built-in battery level indicator, so you always know how much power is left. This unit comes with two USB ports, one Type-C port, and it is compatible with Qi wireless charging.
The RAVPower wowed us with compact design, quick charging, and consistent power delivery. It helped that it was also the least expensive charger we tried. Other units have different talents, not least the Scosche 3-in-1—a true multi-tasker that’s a charger, a portable battery backup, a flashlight, and an emergency strobe. As such, many different quick charging technologies have risen up, with one of the most popular options being from Qualcomm. Depending on your phone, you should ensure that the USB charger you purchase has the proper adapter to support your phone. iPhones come with a proprietary adapter that should be labeled on the box as compatible with your iPhone. For Androids and other devices that use a traditional USB adapter, ensure that your USB port is the same size as the charger or cradle. For modern devices, this will generally be a mini-USB, a micro-USB, or the modern USB Type-C connector, which charges very quickly and efficiently. The rectangular RAVPower PD Pioneer sits on your desk and powers four devices with fast and efficient GaN Power Tech.
Ideal for quick-charging tablets, cell phones, laptops and other mobile devices. Charged a brand new 1S 3.7V 150mah from Horizon on my Macbook Pro. Don’t charge anything outside of a fireproof charging bag. Syncing – Some charging cables for micro USB accessories can double as syncing cables. These cords will sync the data between two of your devices. The electric security systems of the wall charges may include protection against electrical discharge, overcharge, and short-circuit prevention that can blow the battery of your mobile device. In short, the brick-shaped device from Nekmit is a force to be reckoned with. The high power output, high speed of charging, and well-thought-out design make this model virtually one of a kind. To wrap things up, the iClever BoostCube charger provides you with an unrivaled amperage level of 4.8 Amps , a really impressive performance compared to other dual USB devices in the same price range.
For some reason, Indian Railways has 110V power sockets in trains. When charging phones in the train, it always happens that the touchscreen goes wonky. Different phones show different behaviour, from totally non-responsiveness to very heavy lag or some offset in the touch location. Most of these chargers aren’t made by the companies that sell them, and there are some interesting facts about the manufacturers. The manufacturers of the chargers can be looked up from the UL certification number. The oblong Samsung is made in China by Korean RFTech, a manufacturer of mobile phone products. The Samsung cube is made in China by Korean power supply manufacturer Dong Yang E&P. The HP charger is made by Foxlink, who also makes the iPad charger for Apple. The counterfeit chargers are made by anonymous Chinese manufacturers, despite what they claim on the labels.
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 turned out that one side of the cable was just half a millimeter too shallow in the laptop port, preventing a full connection. As an electrical engineer this article really makes me cringe. Not because there is a lot wrong with the tests done, and also not the low technical depth. No, the contents are fine but the constant use of the horrible words wattage and amperage are offending and make my brain hurt. Now unfortunately these words have been misused so much that they have become part of the normal vocabulary, that’s how languages work. However anyone who knows the proper words would never use those. So I hope you will use the proper words next time, they are power instead of wattage and current instead of amperage. At 64 watts, one below its rated maximum, the RAVPower Pioneer RP-PC133 maintained a skin temperature of just 119 degrees Fahrenheit (48.3 Celsius), which is pleasantly cool compared to most chargers we tested.
A USB charger can be purchased separately from a third party. Be sure to read the manual that came with the device to determine what type of USB connector it has. Eyeballing the connector can lead to buying the wrong type of USB charger unless you are very familiar with the different USB standards by sight. USB cables are used to connect devices — such as printers, keyboards and music players — to computers. A USB charger cable features the male Type-A connector on one end, and a very different USB connector on the other. This end plugs into the portable device and is a more compact design to allow for the lack of real estate on handheld electronics. Several USB standards have developed including the Mini-A, Mini-B, Micro-AB and Micro-B connectors. The Micro standards are about half the thickness of the Mini standards, more easily serving slimline products. Virtually all portable, personal electronics feature a USB port, though the connector can vary between one of several standards. Computers use the Type-A standard, which is a flat, rectangular port that contains recessed data pins and exterior power pins that make contact first.
Some chargers use pulse technology in which a series of voltage or current pulses is fed to the battery. The DC pulses have a strictly controlled rise time, pulse width, pulse repetition rate and amplitude. This technology is said to work with any size, voltage, capacity or chemistry of batteries, including automotive and valve-regulated batteries. The output current of a smart charger depends upon the battery’s state. An intelligent charger may monitor the battery’s voltage, temperature or time under charge to determine the optimum charge current and to terminate charging. The charging protocol depends on the size and type of the battery being charged. Other battery types cannot withstand over-charging, being damaged , over heating or even exploding.
Dell calls this feature PowerShare, and it needs to be enabled in the BIOS. On Acer Inc. and Packard Bell laptops, sleep-and-charge USB ports are marked with a non-standard symbol ; the feature is called Power-off USB. Lenovo calls this feature Always On USB. On 8 January 2018 USB-IF announced “Certified USB Fast Charger” logo for chargers that use “Programmable Power Supply” protocol from the USB Power Delivery 3.0 specification. As of USB Power Delivery specification revision 2.0, version 1.2, the six fixed power profiles for power sources have been deprecated. The USB Power Delivery specification revision 2.0 (USB PD Rev. 2.0) has been released as part of the USB 3.1 suite. Power Delivery protocols have been updated to facilitate USB-C features such as cable ID function, Alternate Mode negotiation, increased VBUS currents, and VCONN-powered accessories. The first Power Delivery specification defined six fixed power profiles for the power sources. The power configuration protocol uses a 24 MHz BFSK-coded transmission channel on the VBUS line. The charging device identifies a charging port by non-data signaling on the D+ and D− terminals. A dedicated charging port places a resistance not exceeding 200 Ω across the D+ and D− terminals.
This unit from Aukey had a couple of tricks up its sleeve compared to the others we tested, offering both Qualcomm Quick Charge fast-charging and USB-C. I’ve made a career helping readers easily understand complex things. Since I understand what makes people tick and how technology works, my goal is to advocate for the end user whenever I’m evaluating products. You need to make sure you do not paint the solar panels and usb ports, so put some tape over it, before spraying. Also do not place the tape on top of the protection sheets, because the protection sheets won’t stick to the solar panels. I did not have that kind of luxury, so I had to do it the hard way. To saw the hole in one of the sides, you will have to measure the size of your usb ports and switch and saw a hole at the right size. I did this with a normal handsaw by sawing vertical lines through the place of the hole, so the really thin pieces of wood will break.
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.
The ClipperCreek HCS-40 is another high powered level 2 EV charger that’s safety verified and designed to work with all electric cars.

Schumacher SC-1200A-CA SpeedCharge 12Amp 6/12V Fully Automatic Battery Charger Microprocessor-controlled battery charger. It does a good job charging batteries, but does not have a jump-start option. Some car chargers handle 6 volt and 12 volt; others work with 12 volt and 24 volt. Ask yourself these questions as you shop for a car battery charger. Once the engine is running, your alternator should supply enough charge to keep things going, but it’s a mistake to think that leaving the motor running will eventually charge the battery. Even running it for a long time will leave your battery in a weakened state. The battery needs a proper charge to put things back to normal. Both these types are also called “wet cell” or “flooded” batteries because they contain liquid .
We’ve researched and tested the fastest chargers available and collected our recommendations of the best ones, no matter what device you need to charge. If you don’t want to spend more than $10 or so on a charger and aren’t concerned about USB-C speeds, we recommend ZMI’s PowerCruise C2 36-Watt Dual USB Car Charger with QC 3.0. To be fair, any dual-port USB-A charger from a reputable brand will work as well as any other. For our latest update, we tested another 20 chargers, including some with only USB-A ports, some with just USB-C ports, and some with both. To find the top options in each category, we put the finalists through a number of tests. If you want to have the fastest charge possible on two modern devices—such as an iPhone 8 or later, or a Samsung Galaxy S8 or later—this is your best bet. Save 20% on AT&T accessories Stock up on new chargers, screen protectors, headphones, and more. When charging an older battery, you should leave access to it open (bonnet, boot or rear seat if it’s an old Beetle, for example) and ensure the space is ventilated. The hydrogen sulphide gas emitted is flammable , and batteries can cause sparks.
Mine had high-grade suction cups, which worked most of the time, though when it got very hot, sometimes it’d lose grip out of nowhere and fall down. The dash mount form factor is usually convenient – it lets you use many features of your phone safely, like GPS, Spotify/Pandora, and hands-free communications without a lot of distraction. I do have experience with induction technology as well, though I’ve never tried to use that in my car due to my shocks being less than magnificent, and many of those needing a stable, level surface. Looking for a more basic, down-to-earth cup holder charger, designed to deliver multiple USB charges from your cigarette lighter? While the quality of this as a physical mount isn’t quite up to snuff compared to the previous unit, the induction charging feature is rather convenient and immediate. Suction mounting isn’t ideal, even if this is a good suction cup. It does not provide charge, meaning you will still want a USB adapter which connects to your cigarette lighter. The gooseneck is adjustable, but this may swing around in the plug, or wobble a lot on bumpier roads, or on a vehicle with less than excellent shocks.
What’s more, it includes a 3.0 car charger and micro USB c cable as well. This Choetech USB C car charger is compatible with QC 2.0, QC 3.0, and Apple-2.4A charging.

For a full list of compatible devices, refer to the product description. This really is a fast car charger, but it also has the built in safety features you would expect when that amount of power is in play. We have built in protection from over charging, from over heating – the works. There is other tech at work here too, as the charger can also detect the model of phone you plug in, and adapt the power flow to suit it best. If you connect the negative first, you can cause a short circuit that will damage the battery and possibly other parts of the car’s electrical system. A fast charge can get you out of trouble, but batteries always charge better if done slowly, which is why trickle chargers are so popular.
Appropriately, this is a charger—no muss, no fuss, and average numbers across the board. This unit from Aukey had a couple of tricks up its sleeve compared to the others we tested, offering both Qualcomm Quick Charge fast-charging and USB-C. I’ve made a career helping readers easily understand complex things. Since I understand what makes people tick and how technology works, my goal is to advocate for the end user whenever I’m evaluating products. Stock up on new chargers, screen protectors, headphones, and more. The mount not only features the rounded magnetic circle, but also the vertical alignment magnet at the bottom.

It’s not an issue for home charging, because you can install the outlet you need at home, your place of work or maybe even at a relative or friend’s house. Before we start the comparison, we’d like to talk a little about the power delivery of these units. Some manufacturers like to boast about the charging speed of these units in their advertisements, and it can sometimes get a little confusing. We’ve seen claims of “charges three times as fast” and “lightning fast” being used, and some people new to EVs may not fully understand how EV charging works. Some EVs can only accept 16-amps of power, while others, like the new Audi e-Tron for instance, can accept up to 40-amps. Therefore, make sure you know your car’s charging capabilities before you purchase charging equipment, or you may not pair the correct device with your car’s charging ability, and your driving needs. Only a few years ago there were very little choices for electric vehicle charging equipment. When I got my MINI-E in 2009,BMWpartnered withClipperCreekto supply thehome charging station, or as BMW called it, the “Wallbox” to charge the fleet of 450 MINI-Es in service in the US.
The electricity costs of workplaces charging are often taken on by the employer, which means employees can charge at work for free. In other cases, the employer charges fees to use the charger, but the cost is usually lower than charging at a public charger. Independent public chargers are installed by local businesses or by individuals who want to make charging available on their property. It’s not necessary to be a member of a network to use those chargers. For fast charging, the CHAdeMO and SAE Combo (also called CCS for “Combo Charging System”) are the most used connectors by electric cars manufacturers. It takes around four hours to fully charge a 30-kWh battery car , which allows you to make the most out of driving your EV, especially when you have a limited time to charge. To enjoy all the benefits of charging at home, you need to use a level 2 home charger. Charging an electric car or plug-in hybrid is mainly done at home.Home charging accounts actually for 80% of all charging done by EV drivers. This is why it’s important to understand the solutions available, along with the pros of each.
It can be frustrating to have to wait for assistance — especially when you have somewhere you need to go. You can attract an ever growing number of EV drivers as customers by offering charging points. Fitting of your home charger on a brick or plaster wall, or to another suitable permanent structure. Once you order your charger, they’ll complete a remote risk assessment. During this assessment, they’ll identify the installation as either low or high risk. This will depend on the risk of Covid-19 transmission during the installation process. If you’re identified as a low risk your installation will go ahead. If your assessment results come back that you fall into the high-risk category the installation will be paused for now. I love its improved touch controls to adjust the temperature, too.
Smart battery chargers work much the same when used normally, though intelligent circuitry can reduce charging times considerably. The X-Doria Defense Helix wireless car charging mount with RoboGrip has powered “robotic” arms that automatically open when you place your phone near the charger and then clamp shut after you dock it. You can easily remove it from its charging station with the touch of a button on the dock, which causes the arms to open. It’s compatible to use as a wireless charger for iPhone and Android devices. It’s not as slickly built as the iOttie — and this fast wireless charger doesn’t come with a cigarette lighter adapter — only a USB-C cable — but it’s $30 less. This Qi wireless charger comes with a dual charging USB cigarette lighter adapter. iOttie finally has an “autosense” automatic clamping wireless car charger with a phone mount — and it’s a good one. The Auto Sense Automatic Clamping Qi Charging Car Phone Mount is available in a dashboard mount version or a CD and vent clip version .
Usually, the charger’s positive clamp will be red and the negative clamp will be black. If you need to charge a battery and you’re short on time, the Schumacher SC1325 is the charger for you.

He points out that it took CR 10 hours to recharge the electric-powered Chevrolet Bolt using a 240-volt power source. If you use a standard 120-volt power source, he says, be ready to wait longer than 24 hours for your Bolt to fully recharge. When it comes to owning an EV, Tal says simple charging solutions are found only at the extremes of daily driving routines. For example, Level 1 home charging simply won’t work for anyone who drives longer distances and has no time, or opportunity, to recharge their car during the day. Upgrading to a Level 2 charger for that owner becomes a necessity, especially if the car is fully electric and there aren’t any public charging stations at the workplace or nearby. These cars will need to be charged, however, and given their longer-than-typical range, that can take some serious time. So when does it make financial sense for an owner to get a high-speed at-home charger installed?
Some telltale signs that your battery is running low include a slowing of your engine cranking speed and a dimming of your headlights. You can also purchase a battery tester if you’re concerned about getting stranded. After the charger is connected to the battery, individual instructions may vary. Some chargers may have settings to adjust that will determine the rate at which the battery is refilled, while others can just be turned on. Trickle chargers come in both automatic and manual varieties, and are designed to recharge batteries slowly, over longer periods of time. Finally, the 4-amp maximum charge makes the entire charging process faster than with other models. NOCO’s Genius line also features models with higher amperage, providing more power and, if you desire, a faster charge. It’s the Genius1, however, that delivers the best bang for your buck, making it an excellent introductory product when it comes to charging your own battery.
