Anker ensures that this charger is compatible with all kinds of devices and will evenly distribute the necessary power based on the devices that are plugged in. Plus, Anker offers an 18-month warranty if something goes awry with your charger. When you think of portable chargers, Amazon Basics is likely not the first brand that comes to mind, but their affordable electronic accessories are quickly becoming industry standards. The company has released a 60W charging station with one fast-charging USB-C port and four smart USB-A ports, allowing for a quick charge on any device that you can throw at it. While we haven’t personally heard of any damage from using a USB-C charger other than the one that came with your laptop, there’s always a slim risk when plugging a laptop into an unknown power source. In short, it’s a good idea to buy cables and chargers from reputable sources and think twice about using that cable you found laying on the ground in a conference room. You have probably already used USB connections to charge smaller devices either from your computer or from an outlet. That works well because past USB connections had enough wattage to successfully power up those smaller batteries.
USB-C 1.0 brings in the new power standards and speed advantages similar to that of USB 3.1. Usually the other end of a USB cable uses a Type-B connector. The Type-B plug is the tall plug with the slanted top corners. Variations on Type-B have been widely adopted due to the sheer necessity of having smaller plugs at the client device end. We’re excited that you’re excited about getting your very own promotional USB chargers! We’d be happy to help you customize your order, whether you do that here on our website or through one of our experienced Customer Care Reps. Give them a call at Monday through Friday, 7 a.m. Since these chargers are often used for outdoors, they are usually designed to withstand a lot. That being said, before making your purchase you should make sure that the charger you’re looking at will fit your specific outdoor activity.
Power is extremely important when it comes to these devices, however it is how that power is delivered that is the key – and that is measured in amps. No device on this list delivers power at less than 2.4 amps. There are models out there that do, we’ve seen some with as low as a 1 amp rating – and they are a complete waste of time. They’ll still be trying to get your phone up over 50% even as the sun consumes the Earth itself in a few billion years time. The product itself is small and light, and pretty unobtrusive – there are no bells and whistles here from a design point of view, just a well designed and constructed little device. This is a useful feature on any charger as not only does it make them look really cool , it makes them easier to use in low light conditions. Everything about this product, from the aluminum alloy construction to the nifty red glowing ports screams premium product. Yes, this is certainly one of the better looking models on the market right now, but it is what it has inside that truly makes this one of the standout chargers out there today. This thing looks good and will be a credit to the inside of any car.
USB connector types multiplied as the specification progressed. The original USB specification detailed standard-A and standard-B plugs and receptacles. The connectors were different so that users could not connect one computer receptacle to another. The data pins in the standard plugs are recessed compared to the power pins so that the device can power up before establishing a data connection. Some devices operate in different modes depending on whether the data connection is made. Charging docks supply power and do not include a host device or data pins, allowing any capable USB device to charge or operate from a standard USB cable. In a charge-only cable, the data wires are shorted at the device end, otherwise, the device may reject the charger as unsuitable. The device combines multiple power output ports and may become a true life savior for all of your gadgets. Finally, many multiple USB chargers operate similarly to the average surge protector. They protect your devices from unexpected power surges and prevent them from being damaged using overcharge protection.
4-Port Charging for Smart Phone, iPad, or Tablet, very portable 34W USB AC Desktop Charger! The 34W 4-Port USB Charger can Charge 2 iPhones with each available 5V 1A ports and 2 iPads or tablets. Another way to tell a USB charging cable from a data transfer is to actually test the cable. Since the USB Implementers Forum does not have a standard, symbol, label, or icon to distinguish these cables, you actually have to use them to find out. Because the USB Implementers Forum doesn’t have any rule enforcing USB manufacturers to label or differentiate charge-only cables from data-transfer cables, it is almost impossible to tell them apart. However, there are still some proven ways to find out if a USB cable is charge-only or supports data transfer. All USB cables have the positive and negative wires but not all USB cables have the data exchange wires — this is why some cables only charges your smartphone. Lifepowr’s $25 USB-C cable, called “the Beast,”is wrapped in a stainless steel housing for durability. It handles both high-speed data transfer — USB 3.1 at up to 10Gbps — and high-power charging but costs $32. I was terrified its flexing coils would catch an arm hair and give it a painful pluck, but I didn’t have any problems.
You might still find a USB Type-B port on some devices, but it’s becoming quite rare. Keep in mind, however, that the consequences can be worse than just slow charging. There are cases of people blowing up devices with the wrong type of cable, and other instances where one device may flatly refuse to work with another device’s USB-C cable for unknown reasons. The assumption, in this case, is that the device is refusing to connect through a given cable to protect itself. In the USB 1.0 and 2.0 specs, a standard downstream port is capable of delivering up to 500mA (0.5A); with USB 3.0, it moves up to 900mA (0.9A). The charging downstream and dedicated charging ports provide up to 1,500mA (1.5A). USB 3.1 bumps throughput to 10Gbps in what’s called SuperSpeed+ mode, bringing it roughly equivalent with first-generation Thunderbolt. It also supports a power draw of 1.5A and 3A over the 5V bus. There are now five — and soon to be six — USB specifications — USB 1.0, 2.0, 3.0, 3.1, 3.2, and USB4. The USB4 spec has been published but isn’t actually available in any shipping devices yet, so there are five USB standards for now.
A budget-friendly yet highly efficient model from iClever features a foldable design, making it a perfect travel option. Plus, this tiny device is capable of delivering up to 2.4 Amps, enough to charge the newest gadgets in a matter of hours.

A “smart charger” should not be confused with a “smart battery”. A smart battery is generally defined as one containing some sort of electronic device or “chip” that can communicate with a smart charger about battery characteristics and condition. A smart battery generally requires a smart charger it can communicate with . A smart charger is defined as a charger that can respond to the condition of a battery, and modify its charging actions accordingly. If both the charge current and the battery capacity in the C-rate ratio is multiplied by the battery voltage, the C-rate becomes a ratio of the charge power to the battery’s energy capacity. For example, when the 100 kWh battery in a Tesla Model S P100D is undergoing supercharging at 120 kW the C-rate is 1.2C and when that battery delivers its maximum power of 451 kW, its C-rate is 4.51C. Charge and discharge rates are often given as C or C-rate, which is a measure of the rate at which a battery is charged or discharged relative to its capacity. The C-rate is defined as the charge or discharge current divided by the battery’s capacity to store an electrical charge. The C-rate is never negative, so whether it describes a charging or discharging process depends on the context.
After that, the voltage decreases, which indicates to an intelligent charger that the battery is fully charged. Such chargers are often labeled as a ΔV, “delta-V,” or sometimes “delta peak”, charger, indicating that they monitor the voltage change. The first stage is referred to as “bulk absorption”; the charging current will be held high and constant and is limited by the capacity of the charger. When the voltage on the battery reaches its outgassing voltage (2.22 volts per cell) the charger switches to the second stage and the voltage is held constant (2.40 volts per cell). The delivered current will decline at the maintained voltage, and when the current reaches less than 0.005C the charger enters its third stage and the charger output will be held constant at 2.25 volts per cell. In the third stage, the charging current is very small 0.005C and at this voltage the battery can be maintained at full charge and compensate for self-discharge. Fast chargers make use of control circuitry to rapidly charge the batteries without damaging any of the cells in the battery.
To add on top of this, it charges your iPhone quickly as compared to the traditional charger. ESR’s accessories have always been on top of my list, especially for my iPhone and MacBooks! Be it a case for iPhone 11 or a sleeve for MacBook, ESR products always deliver the best and are durable too. And if you’re wondering what’s the output of this USB-C adapter, it’s 36W and this is an ideal companion when you have less time to charge your iPhone while traveling. Part of the issue is whether or not a charger supports a protocol known as USB-C Power Delivery, usually abbreviated to USB-C PD – and if so, which version? This is a method by which a charger and the device connected to it negotiate the power that will be supplied in terms of both volts and amps. These little devices can also be extremely useful to have on hand during an emergency. They are so small – and also pretty durable – you can pop one into the glove box and leave it there indefinitely.
But you can also be sure that, should the need arise, it will be right there ready to charge up your phone or GPS if you desperately need it. We finish up our marathon march through the best USB car chargers with this product from CHOETECH. This is the second style of charger we have come across on our list where the two USB Ports serve separate functions. On the other hand, remember what we said about the TrimDish product above, that the power cord was kind of the Achilles heel of USB chargers? Bearing that in mind, this product from AmazonBasics could be a very handy standby charger. Buy it – along with a more traditional design for everyday use – and pop this one in the glove box. To be perfectly blunt, there’s not really much about these products in terms of stand-out features. Yes, they do have wide compatibility across a range of electrical devices.
Micro-USB connectors, which were announced by the USB-IF on 4 January 2007, have a similar width to Mini-USB, but approximately half the thickness, enabling their integration into thinner portable devices. Mini-USB connectors were introduced together with USB 2.0 in April 2000, for use with smaller devices such as digital cameras, smartphones, and tablet computers. The Mini-A connector and the Mini-AB receptacle connector have been deprecated since May 2007. Mini-B connectors are still supported, but are not On-The-Go-compliant; the Mini-B USB connector was standard for transferring data to and from the early smartphones and PDAs. Both Mini-A and Mini-B plugs are approximately 3 by 7 mm (0.12 by 0.28 in). To accomplish this, a locking device was added and the leaf-spring was moved from the jack to the plug, so that the most-stressed part is on the cable side of the connection.
