To find the best of the best, we researched user ratings and professional reviews alike, searching for units that stand out in such a crowded field. Each unit we selected for testing is unique from the others, offering a feature you can’t get elsewhere. While it doesn’t support Qualcomm Quick Charge, it does feature Anker’s proprietary PowerIQ and VoltageBoost tech—features that give this sleek unit enough oomph to charge two iPads at the same time. Small, mighty, and a consistent performer, the Anker is a good choice, especially at a price that’s competitive with more basic chargers. If your needs range from phones, to phablets, and even to full-size tablets, this Anker has got you covered. When the weather may be suitable for flying, I bring my batteries to the office and charge them in the office. This charger works, but neither does it balance very well nor is the cut-off voltage ideal.
To help you understand how to use your USB chargers, we’ve answered some key questions on the safety of USB charging. The Custom Basecamp™ Explorer Power Bank Flashlight is a lifesaver during a power outage. Not only is it a flashlight, but the 5V USB power bank on the bottom also keeps electronic devices charged. You can’t go wrong with any of our top picks, but we recommend theHiluckey Solar Power Bank. The great thing is that the average solar charger comes with at least a few, if not all, of these features. Extras like the LED flashlight can be real lifesavers, so don’t be too quick to choose a plain jane model because you want to save money. More often than not, the extra features won’t increase the cost very much, if at all. Take the time to look through a few model options because the chances are pretty good that you will find a model that has both the power you need and the features you want without having to break the bank.
Most USB car chargers are splash resistant and can handle a few drops of water on the exterior shell. However, anything more than that and the USB charger is bound to malfunction and see an untimely death. Now that you’ve had a look at some of the best USB car chargers that money can buy, you need to know what to look out for when purchasing a USB car adapter. Here is a list of some of the most important considerations to bear in mind. Not only do they present a risk to you, the use of uncertified chargers may also damage your phone . It’s important to check the rating of the chargers, to ensure that the output is correct for your device. Do not simply assume that if they have the same physical connection the output will be the same. A supply of an incorrect charge may result in damage to your device and the potential risk of overheating and fire. When it comes to USB networks there is always one host and one device. The majority of the time the computer is the host and your appliance is the device.
The hub may also have some non-removable functions in place of ports. A self-powered hub is a device that provides high-power ports. Optionally, the hub controller may draw power for its operation as a low-power device, but all high-power ports draw from the hub’s self-power. Proprietary, hazardousExisting for specific proprietary purposes, not inter-operable with USB-IF compliant equipment and possibly damaging to both devices when plugged in. In addition to the above cable assemblies comprising two plugs, an “adapter” cable with a Micro-A plug and a standard-A receptacle is compliant with USB specifications. On the device side, a modified Micro-B plug (Micro-B SuperSpeed) is used to cater for the five additional pins required to achieve the USB 3.0 features (USB-C plug can also be used).
Charging power is quite strong with this port, offering 2.4A at every plug-in. On the other hand, you can definitely use your USB-C laptop charger to juice up your smartphone. Again, those safeguards we talked about earlier will allow the charger and battery to talk with each other and automatically default to the fastest allowed charging speed. This is what we’d generally think of as a “slow” charger, since the majority of modern chargers are much faster now. Having some knowledge regarding USB chargers and cables, you should be able to find the perfect charger to fit your needs. You can also eliminate that power-strip containing numerous individual chargers cluttering up your kitchen counter or another area of your home by consolidating chargers.
In our tests, one of the power profiles was an unusual 12 V, 1.75 A , which didn’t match the 12 V, 1.5 A specs listed on the charger itself. If you don’t want to spend more than $10 or so on a charger and aren’t concerned about USB-C speeds, we recommend ZMI’s PowerCruise C2 36-Watt Dual USB Car Charger with QC 3.0. To be fair, any dual-port USB-A charger from a reputable brand will work as well as any other. But the PowerCruise C2 has a slight edge because it’s the rare charger that supports Qualcomm’s Quick Charge 3.0 charging technology on both ports , and it has the most aesthetically pleasing design in the category. The Nekteck PD 45W car charger is the only model we tested that includes a USB-C–to–USB-C cable, a $10 to $20 value if bought separately. You can keep this cable in your car to charge your Android phone, computer, or iPad Pro without having to buy a separate accessory. We’ve verified that the cable adheres to standards; it’s not only safe, but it also has a sturdy build quality. In addition to passing our own tests, the Nekteck charger has been certified by the USB-IF, which means it has been independently tested for safety.
Most multiple USB port chargers have become quite affordable and practical additions to any high-tech home or office. However, there are some that could stretch the limits of your wallet. Always ensure that you don’t buy something that reaches beyond your intended use. And if you’re just driving across town, the faster your phone charges, the better. If you own a QC 2.0 device, however, ask yourself if paying extra for a QC 3.0-capable charger is worth it. Without fancy testing equipment, it can be hard to gauge whether you’re getting what you paid for.
Versatility is one of the main highlights of an unwired USB charger. A car charger is usually small in terms of form factor and has multiple charging ports to support numerous devices. They also have in-built safety features that safely charge smartphones and tablets alike. Furthermore, they are easy to use and can comfortably fit in the USB output port of the automobile. Before you learn more about the best USB car chargers, it’s crucial to take a look at the kind of USB car chargers. For the days when all of your devices seem to run out of juice at the same time, there is the BigBlue 3. The BigBlue 3 comes with three USB ports that can simultaneously charge up to 5W/2.4A each.
They quickly suck the battery power from your computer and can slow down the operating speed. These small devices don’t differ from each other all that much. Some have an indicator light, others have illuminated ports. Some feature Quick Charge for devices that support it, others don’t. One attribute they all share, however, is two USB ports—i.e., the days of the single-port car charger are long over. There are plenty of options for keeping your phone or tablet charged while on the go. We’ve already taken a look at portable USB battery packs, as well as the USB-C variety. A bolder noncompliant scheme assumes that 500mA will be available and instructs users to plug only into powered ports and hubs that are capable of 500mA.
Most car chargers, if treated well, can last for a few years. However, like most electronic components, car chargers too can suffer sudden failure. Thankfully, since most have inbuilt-safety features, your devices and you are kept safe. Before you make that all-important purchase, revisit our list of the 11 best USB car chargers and choose the one you like the most. Much of its popularity arises from its super-quick charging speeds coupled with dual smart charging technologies. Built into this compact car charger is a PD 3.0 PPS fast-charging chip and a QC 3.0 fast charging chip. The 2 Type-C USB ports have a 65 W and 30 W rating, while the QC port has a rating of 18 W. The sheer brilliance of this charger is its ability to fast charge iPhones and Android smartphones and tablets.
