What to look for in a wall charger
Same as with any tech, USB chargers have properties that determine whether a charger is good and fit for your needs or not. The main criteria for picking the best charger for your phone or tablet are amperage, the quantity of ports, and support for improved charging, which we have described in detail below.
Our list is mainly focused on chargers with standard USB type A ports, so if you’re in need of a charger using the USB type C connection, your only option on our wall charger list will be CHOETECH’s charger. We are also focusing on the American market, so all but one (Syncwire) phone charger on our list use the type-A electric plug. This list of different electric plugs will help you understand which one you are using.
Check Wall Charger Amperage!
Undoubtedly the most important characteristic of a charger, the amperage (measured in amperes A) basically determines how many electric particles go through the electrical system in a certain amount of time. The best amperage you need in your charger is 2.4 A per port, which is enough to charge even tablets at max speed, not to mention phones, with 2 amps being the minimum for a good charger. This makes you do a bit of math with some chargers with multiple ports since total amperage of a charger is split between all the ports.
For example, if you use the Anker 4-port 8A charger to charge three devices, they will all charge with 2.4A, which leaves only 0.8A (8 – 3 x 2.4A = 0.8A) for the last port. This, however, doesn’t mean that the fourth device you connect to the charger will charge at a measly 0.8 amps since chargers split their power output over all ports. So four devices will all charge at 2.0A (8 / 4 = 2A) which is an important detail to note when using a multi-port charger – when charging a lot of devices at the same time, the power will be split among them, making charging times longer with a less powerful charger.
Voltage (measured in volts V) is another important characteristic of current since, in Layman’s terms, it describes how much a power source wants to move charged particles within an electric chain. Most chargers these days provide a 5 V current, with more modern chargers providing slightly more (5.2 V, for example) for different new devices and interfaces. Wattage (measured in watts W) is what connects amperage and voltage and is the value that describes the actual amount of energy over time that a charger can dish out. Mathematically it is P=V x I or wattage = voltage multiplied by amperage. So if we know that a charger provides a 5 V current, simple math will tell us that its amperage will be wattage divided by 5. As long as you know either value, you will be able to tell how powerful a charger is.
Quantity of ports
Depending on how many devices you use in daily life, you may need more than one or even two charging ports, but at the same time, you have to consider the size and portability of the charger. Also, the previously mentioned amperage drop per port is important to consider depending on how often and how long you use the charger.
Support for improved charging
The box making enough amps go into your phone is a very simplistic and basic way to describe how charging works since there are hundreds of different components in the circuitry to make sure it works as intended. This leaves a lot to improve and build upon, which is what larger companies do by implementing various forms of smart charging.
The purpose of smart charging is making sure your phone or tablet gets charged with the most appropriate power input, which can decrease charging times and to some extent, power usage. Basically, these technologies allow the charger to adapt to your device to provide optimized charging as well as lowering voltage when your device is almost charged as to not damage or wear out the battery. Different companies come up with their own technologies to improve the charging process, like Anker’s PowerIQ and VoltageBoost, or RAVPower’s iSmart. However, for the consumer, there isn’t a huge difference between these charging technologies, as long as one of them is implemented in the charger you’ve picked.
An exception to this “anything goes” principle is QuickCharge (QC) by Qualcomm, which takes shortening charging times to the next level. For example, QC version 3.0 promises what Qualcomm calls 5 for 5 – which is 5 minutes of charging providing enough power for 5 hours of device usage. However, such a technology is very complex, so it has to be implemented not only in the charger but in the phone or tablet as well, making it a waste of money for people who don’t own such a device. You can check Qualcomm’s web page to see the details about QC, as well as a list of devices that use it and who knows, your device might be listed there.

Frequently Asked Questions
Same as with all technology, many smaller aspects related to charging are unknown to the regular customer, so here is a short list of tips for keeping your phone battery in top shape, followed by a short video by Techquickie.
Q: If my older device requires lower amperage to charge, can a powerful charger damage it?
A: No. Modern charging devices, as well as power systems within your phone or tablet, are all able to cut down higher amperage to fit the device’s needs, i.e. a 2.4 amp charger won’t fry a device that needs only 1.5-2 amps to charge. In fact, a more powerful charger will simply charge your device faster without any danger. If your device is around a decade old, though, you should probably use the charger it came with or find a charger with lower amperage.
Q: Is it better to replace the charger that came with my device to improve charging?
A: No, unless it’s broken. While there is nothing much to these hard-wired chargers, they have been engineered to fit the product that it came with, which ensures close to optimum charging and makes most previously mentioned smart charging technologies pretty much unnecessary (aside from QuickCharge, which is a huge boost to charging speeds).
However, if you want to charge different devices with the same charger, slower charging is almost guaranteed since the charger is not designed to adapt to various devices. Of course, if you’re looking for multiple ports or other special features, a well-designed new charger will never be worse than the original.
Q: Can different cables affect charging speeds?
A: Yes, but not too much. When looking at differences purely between cables themselves, you have to look for thicker cables, since they can support higher amperage. As to whether the version of your USB cables makes any difference, you have to consider the port you are using. When using chargers, there is no difference between 2.0 and 3.0 cables because of the simplistic nature of the charger.
However, if you’re charging from your PC’s USB 3.0 port, only a USB 3.0 cable will ensure the higher charging speeds (up to 1.5 A, as opposed to USB 2.0’s 0.5 A), while a USB 2.0 cable will cut that speed down to 0.5 amps. Your PC’s USB 2.0 port will always provide 0.5 A power regardless of the cable type.
Q: What are the most important tips to charge my phone’s battery correctly?
A: Charge it in small bursts
