On Dell, HP and Toshiba laptops, sleep-and-charge USB ports are marked with the standard USB symbol with an added lightning bolt or battery icon on the right side.
China, the European Commission and other countries are making a national standard on mobile phone chargers using the USB standard. On October 22, 2009, the International Telecommunication Union announced a standard for a universal charger for mobile handsets (Micro-USB). A 10 amp-hour battery could take 15 hours to reach a fully charged state from a fully discharged condition with a 1 amp charger as it would require roughly 1.5 times the battery’s capacity. The most sophisticated types are used in critical applications (e.g. military or aviation batteries). These heavy-duty automatic “intelligent charging” systems can be programmed with complex charging cycles specified by the battery maker. The best are universal (i.e. can charge all battery types), and include automatic capacity testing and analyzing functions too. For example, for a battery with a capacity of 500 mAh, a discharge rate of 5000 mA (i.e., 5 A) corresponds to a C-rate of 10C, meaning that such a current can discharge 10 such batteries in one hour.
If we were using our charger at a desk, we’d prefer a similarly priced model with USB-C. Anker’s 18-month warranty is on par with many of its competitors’ offerings. On the rare occasions Wirecutter staffers have had to take advantage of the protection, they’ve found the process to be quick and easy. They’re less than half the volume of Apple’s comparable 20 W charger. Based on those criteria, we’ve tested dozens of models over the years, including some with just USB-C ports, some with just USB-A ports, and some with both. is not one for the nightstand as each port has a green LED, but it should prove handy for a shared charging space at work or perhaps in the kitchen at home.
Dell adds a lightning bolt icon and calls it the “PowerShare” while Toshiba uses the term “USB Sleep-and-Charge.” The sleep-and-charge USB ports may also be marked with the acronym USB over the drawing of a battery.

The all-metal construction, in addition to looking great, also allows for superior heat dissipation too – a design choice that is a nod to the incredible power that will be flowing through this bad boy.
No, cables differ both in terms of data transfer speed and power as well as protocol support. Some USB-C cables only support the older USB 2.0 standard, while modern cables can take advantage of USB 3.2, the latest and fastest standard (until 4.0 releases). Some cables can only carry 20V 3A power, while others carry 20V 5A, sufficient to power devices like laptops and monitors. You should always check which type of cable you’re using before plugging it into a device, particularly if it’s aftermarket or you bought it from a third party.

Because USB chargers are relatively simple devices, it’s the little touches that make a difference. The majority of cell phones and tablets will charge fastest at 18w PD, so if you use both ports at the same time, you’ll end up with longer charge time. To finish everything, I’ve painted a little 0 and 1 beneath the switch, so I could see if the solar usb charger is on, without having to plug in my usb device. The best way to do this is to first glue the battery connectors in place, then the batteries, then the switch and the usb ports, and then the cover. Included Smart IC Technology detects your device and provides optimal charging current to each port. Rounding out this sleek charger are safety features to protect against overheating and overloading. When solid workmanship matters, you want the Syncwire charger by your side.

Data cables have four wires and as such, have thicker outer insulation/lining than their charge-only counterparts with two less wires. What differentiates a charge-only USB cable from a data cable is the how they are produced. More precisely, their wiring system — the number of wires within the cable. Underneath the fancy body of your USB cables are wires, right? The number of wires a cable has will determine if charges your phone, transfers data, or does both. Ever tried to transfer files from a PC to your smartphone using a USB cable but the computer doesn’t recognize your device? But usually, there’s nothing wrong with your USB cable, it’s just not built for data transfer. both your phone and your laptop — at least if you have an Apple MacBook, Google Chromebook Pixel, or a higher-end model from Dell and HP.
Incompatibilities between competitive systems exist, willingly or by oversight. To support charging and data communication when using the DCP, a Y-shaped cable is offered that connects to the original USB port for data streaming and to the DCP port to satisfy charging needs. Standard A and B USB plugs, as illustrated in Figure 1, feature four pins and a shield. Pin 1 delivers +5VDC and pin 4 forms the ground that also connects to the shield. The two shorter pins, 2 and 3, are marked D- and D+ and carry data. When charging a battery, these pins have no other function than to negotiate current. With 5V and 500mA available on version USB 1.0 and 2.0, and 900mA on USB 3.0, the USB can charge a small single-cell Li-ion pack.
This charger is a great choice if you often carry standard products such as tablets and rechargeable Bluetooth speakers in your journeys.
