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.
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.
A variety of (non-USB) standards support charging devices faster than the USB battery-charging standard (USB-#BCS). When a device doesn’t recognize the faster-charging standard, generally the device and the charger fall back to the USB battery-charging standard of 5 V at 1.5 A (7.5 W). When a device detects it is plugged into a charger with a compatible faster-charging standard, the device pulls more current or the device tells the charger to increase the voltage or both to increase power . USB chargers are power adapters that plug into an outlet and accept a USB cable to provide power to a device. They have one or more charging ports for connecting a device. Fortunately, if your system gets power via USB-C, you can easily find a third party charger that weighs less, looks better and may even have additional ports for charging other devices at the same time.
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.
The difference in price between models is minor when the device is priced on the basis of the number of ports. USB Type-C is backwards-compatible with older versions of USB A, but you will need an adapter that has a Type-C connector on one end and an older-style USB Type A port on the other end. You can then plug your older devices directly into a USB Type-C port. The device will charge like any other Type A in-wall charger. Leviton USB In-Wall Chargers have USB ports and most models have 15 Amp or 20 Amp Tamper- Resistant Outlets. They are designed for adapter-free charging for two USB-powered electronic devices at once, leaving the outlets free for additional power needs.
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.
Once you get the chargers that will work with your phone, you can narrow down your search by deciding which type you want to buy. Here is a list of some of the most popular types available online. So, these are the variants of boAt type-C chargers you can opt for. Once you have zeroed in on the variant you want to buy, all you have to do is add it to your cart and check out your order. Once the order has been placed, you can expect your new charger to arrive at your doorstep. Once you have your new charger, you can bid goodbye to charging woes and ensure that all your devices are juiced-up so that they run smoothly and efficiently. However, while it is present in the wall chargers that ship with the devices themselves, and a few third-party solutions, Quick Charge 4 is not in any battery products yet.
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.

It’s compatible with most 5V USB devices like smartphones, tablets, cameras, and more. With its six smart identification USB ports, it can adjust the output power to accommodate each device and charge compatible devices up to 80% in 30 minutes. A variety of 10 safety features work together to protect your devices. USB Type-A connectors are extremely common and will likely be at one end of a lot of USB cables nowadays. You can connect various devices such as smartphones, cameras, keyboards, and more to computers to transfer data, or plug into wall chargers to charge these gadgets with a Type-A port. The longer answer is that the age of your device plays an important role, dictating both how fast it can be charged, and whether it can be charged using a wall charger at all. Shortly thereafter, USB devices that implemented this spec started to arrive.

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.
