The $57 Aukey PA-Y13 46W USB-C Charger will charge even a top-end MacBook pro, though its 46-watt USB-C port won’t do it as fast as Apple’s 87-watt charger. But unlike Apple’s chargers, you can also plug in devices using regular and quick-charge USB-A ports. Apple’s 18-watt USB-C power adapter isn’t cheap at $29, and it’s bigger than newer third-party chargers that can deliver more power. But it’s a clean, solid adapter design that’s good for charging tablets, phones and other smaller devices. With Apple’s $19 USB-C to Lightning cable — also expensive — you can charge your iPhone or iPad fast, too. Barnes & Noble Nook Color devices also require a special charger that runs at 1.9 amperes.
Do note that no cable is supplied in the box, so you will need to provide your own. The compact dimensions of the Omnia plug also make it ideally suited for travel – just remember to pack an adaptor as this one has a UK three-pin plug . Here are the essential—and nonessential—items to carry in your car during winter driving to ensure you get to your destination. Scosche’s PowerVolt Power Delivery Dual 18W USB-C Car Charger is a good alternative to the PowerVolt PD40, as it performed equally well in our tests. But it has a larger charging face, usually sells for a few dollars more, and doesn’t support 20-watt charging for MagSafe. Scosche offers a three-year warranty and makes service replacements easy. Wirecutter staffers who have taken advantage of the company’s warranty have reported a fast and pleasant experience.
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.
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.
It’s never been tested in a surge situation but it gives me peace of mind. I have an older version so it is slow if I have both my phone and tablet plugged into the USB ports, so I usually plug one into the plug instead. Which electrical practices, and so which charger, are best suited for use depending entirely on the type of battery. NiCd cells must be fully discharged occasionally, or else the battery loses capacity over time due to a phenomenon known as “memory effect.” Once a month is sometimes recommended. Rapid charging results in even faster recharge times and is limited only by available AC power, battery type, and the type of charging system. Battery cases are small power banks attached to the rear side of a mobile phone like a case. Power may be delivered through the USB charging ports, or wirelessly. Some power banks have a pass-through charging feature which allows providing power through their USB ports while being charged themselves simultaneously. Often a timer charger and set of batteries could be bought as a bundle and the charger time was set to suit those batteries. If batteries of lower capacity were charged then they would be overcharged, and if batteries of higher capacity were charged they would be only partly charged.
Motor vehicles, such as boats, RVs, ATVs, motorcycles, cars, trucks, etc. have used lead–acid batteries. These batteries employ a sulfuric acid electrolyte and can generally be charged and discharged without exhibiting memory effect, though sulfation will occur over time. Typically sulfated batteries are simply replaced with new batteries, and the old ones recycled. Lead–acid batteries will experience substantially longer life when a maintenance charger is used to “float charge” the battery. This prevents the battery from ever being below 100% charge, preventing sulfate from forming. Proper temperature compensated float voltage should be used to achieve the best results. Such chargers are permanently installed and equipped with temperature compensation, supervisory alarms for various system faults, and often redundant independent power supplies and redundant rectifier systems. Capacity of the charger is specified to maintain the system load and recharge a completely discharged battery within, say, 8 hours or other interval. Power-factor correction chargers can more closely approach the maximum current the plug can deliver, shortening charging time. Electric vehicle battery chargers come in a variety of brands and characteristics.
Note that USB-IF does not yet have a testing protocol for chargers with more than 1 USB-C port. Properly designed multi-port chargers will intelligently split the power delivery when multiple devices are connected to not over-drive the charger. Poorly designed chargers can get extremely hot when multiple devices are connected. Few broadly available chargers support the maximum 100 watts power delivery (20V @ 5A) although many support ~80-90W. Laptops capable of receiving 100W via USB-C rarely do so and typically step down to lower charge rates quickly as battery temperatures rise. Most laptops will get similar charge speeds across the watt class.
Travel-friendly, the PowerCore+ measures a backpack-friendly 6.5 x 3.1 x 0.9 inches in size weights 1.3-pounds. Fortunately, the PowerCore+ doesn’t take too long to recharge on its own courtesy of the 30W USB-C wall charger that can refill the entire battery in just over four hours. If you’re wary of using a third-party charger with your smartphone or tablet, you should know that Apple sells a USB-C power adapter of its own. You may want to pick one up since Apple no longer includes a charger with the purchase of an iPhone. It has the ability to recharge an iPhone 12 Pro Max up to 50% in just a half-hour. It features a foldable plug but does not come with a USB-C cable. For a more affordable charger that includes a USB-C cable, consider the Nekteck’s slightly larger 100-watt charger instead.
The USB device costs $55 alone, and about $20 more with a charging cable or $30 more with the company’s stainless steel-wrapped USB-C charging and data cable. It’s worked well for me over months of road trips and daily use in our minivan. A quality vaporizer battery needs a quality vaporizer charger to match.

USB4 increases speeds and charging power to match Thunderbolt 3, up to 100W. This type of connection now provides enough power to juice up most laptops (particularly the Type-C 3.0 version). That’s why laptop charging is a new topic of conversation for USB connections, especially now that more laptops are entering the market with USB-C charging compatibility. In our tests , the Anker and RAVPower models performed very closely to one another. But the reason the final list skews almost totally to RAVPower is that the company is just killing it in the value arena. In nearly every head-to-head match-up, the RAVPower charger beats its equivalent Anker model on price.
