It’s black, slightly textured, and has the AmazonBasics logo on top. There’s a long power cord supplied and a power switch on the side. Small yet mighty, it keeps your devices charged on the go or at home and comes with a long charging cord. If you don’t fancy the black option, it’s available in navy blue or white, too — and its solidly-positive reviews make this well worth the money. For example, I almost always charge my ASUS Chromebook C302 with my Pixel 2 XL’s charger when I’m at home, and I’ve used my C302’s charger on my Pixel multiple times when I’m out. I leave the C302 charger in my bag all the time and the stock Pixel charger plugged up, so it works out well. This is why you can use a Quick Charger on older smartphones that don’t support Quick Charging technology—both the charger and the battery have the necessary safeguards in place to keep anything bad from happening. The phone will just charge at the normal speed its designed for. With its smaller connector head and symmetrical, reversible orientation, it fits easily into phones, tablets, laptops and more.
Many are small and compact in order to be easily portable. A few others are large and intended to spend most of their time on a desk or counter top in order to create a designated charging station. Still others are intended for use in your car for charging on the go. Purchasing a charger with four ports when you have six devices will be counter productive because you still won’t be able to charge everything at once. If you don’t need one of those 60-watt or higher, heavy-hitting chargers, you can usually get by with spending considerably less. The Aukey PA-T16 is great for those with two devices that support Qualcomm QC 3.0, while its larger relative the Aukey PA-T11 is suitable for those with several such devices.
Apart from the above, this Choetech charger is also quite affordable compared to its peers. Plus, there are built-in features in place to reduce the risk of damage and overheating. If we go by the testament of one of the users, this Aukey charger can add 50% to a Pixel 2 in around 30 minutes. What makes the deal even sweeter is that the box includes a meter-long USB-IF certified Type-C cable. The example is specific to CPUs but the idea holds for any power source and load. You didn’t measure transient response, which is admittedly tough to do right, so you wouldn’t see the advantage it provides. Tim Tyrell needed a new charger for his iPhone so he turned to eBay.
Chargers that are rated up to two amperes may be used to maintain charge on parked vehicle batteries or for small batteries on garden tractors or similar equipment. A motorist may keep a charger rated a few amperes to ten or fifteen amperes for maintenance of automobile batteries or to recharge a vehicle battery that has accidentally discharged. Since a battery charger is intended to be connected to a battery, it may not have voltage regulation or filtering of the DC voltage output; it is cheaper to make them that way. Battery chargers equipped with both voltage regulation and filtering are sometimes termed battery eliminators. The problem is, the magnitude of “delta-V” can become very small or even non-existent if high capacity rechargeable batteries are recharged. This can cause even an intelligent battery charger to not sense that the batteries are actually already fully charged, and to continue charging. However, many so called intelligent chargers employ a combination of cut off systems, which are intended to prevent overcharging in the vast majority of cases.

Arguably the most useful benefit of USB’s power capabilities is the ability to charge batteries in portable devices. Nonetheless, there is more to battery charging than picking a power source, USB or otherwise. This is particularly true for Li+ batteries, where improper charging can not only shorten battery life, but also become a safety hazard. A well-designed charger optimizes safety and the user experience. It also lowers cost by reducing customer returns and warranty repairs. Arguably the most useful part of USB’s power capabilities is the ability to charge batteries in portable devices, but there is more to battery charging than picking a power source, USB or otherwise. This is particularly true for Li+ batteries, where improper charging can not only shorten battery life, but also can be a safety hazard. Charging batteries from USB requires balancing battery \”care and feeding\” with the power limitations of USB as well as the size and cost barriers ever present in portable consumer device designs.
We also tried these dual-port setups with a real laptop, a ThinkPad X1 Carbon and used a USB-C power meter to see how much the charger was delivering. Whereas most car chargers are plastic, the PowerCruise C2 is made of silver-toned brass. It also sports a glowing ring between the charging stem and the 0.8-inch-tall head, though the ports themselves aren’t lit. Although you’d be able to charge some devices slightly faster with our top picks, the difference wouldn’t be big enough to be worth spending more money on a new model right now. Whether you’re on the way to the airport, an important meeting, or even for an family event, a car charger can fast-charge your electronic device while you’re on the go. They have become popular owing to their small-sized form factor, design, and utility.
However, prior versions of USB could handle a limited amount of power, which is why laptop chargers have typically retained their larger, bulkier cables. The fact of the matter is that if you’re packing the right kind of charging cable , and your laptop or device was released in the past couple of years, you’ll be in very good shape. The key, of course, is getting one of the latest and greatest USB-C power delivery chargers. Thankfully, I’ve spent the past few weeks testing some of them, and I’ve found some go-to choices for fast charging on the go. You can find no shortage of small, $10-ish, dual-port USB-A chargers from reputable brands. AmazonBasics’s Dual-Port USB Car Charger, Anker’s PowerDrive 2, Aukey’s CC-S7, and Scosche’s ReVolt all perform identically to one another. Some models are shorter than others and end up looking like they’re part of your car when installed, and some have glowing ports that make it easier for you to plug in a cable when it’s dark.
System software again handles communication with a USB host and sends commands to the charger. The MAX8394 manages the hardware aspects of charging and provides simple hooks for setting charge parameters relevant to USB and adapter charging. USB input current limits are preset to ensure that specified limits are not exceeded; a user-set current is used for adapters. The charger also supplies a complete set of status and fault signals to the system. A dual-input charger like the MAX8844 handles charging from both USB and adapter sources. This device also protects against input overvoltages up to 28V. BC1.1 describes hardware detection methods to determine port type.

Hi Dan, I made no progress with the issue with the Apple 87W wall charger and the Apple usb-c charge cable.
With the display off on each phone, we monitored the charger’s output. Determining whether a car charger lives up to its promise entails more than connecting it to a phone and charging. Testing requires special equipment to measure output and verify stated performance claims. Another aspect of noncompliant charging relates to the treatment of USB suspend. USB 2.0 stipulates that all devices must suspend (draw less than 2.5mA) after a set period of bus inactivity. Since charging was never included when this was written, there was no consideration for a device continuing to charge a battery while off, but still attached. However, since most USB hosts do not actually turn off power, this violation of the specification rarely prevented charging. In fact, due to heat dissipation, most portable devices would not tolerate a 2A linear charger design under any conditions.
The expectation is that integrated circuitry will be used for this, as with the MAX8895 in Figure 2, or that this circuitry will be included in the USB transceiver. Nevertheless, adding port detection, or at least some subset of it, to an existing charger may sometimes be preferred. Figure 4 shows circuitry for a rudimentary USB charger detection scheme that operates under control of the system microcontroller. This approach can detect a DCP, but cannot distinguish between an SDP and a CDP. It treats both as an SDP, which means that in some cases it can miss the opportunity to draw more charging current from a CDP. The MAX8895 charger self-enumerates with a USB source to optimally set charge current depending on the type of connected power source.
