USB Phone Charger
What features do you need in a power bank?
Seeing your phone or table running juice when you’re nowhere near an outlet is stressful. Fortunately, there is no shortage of third-party backup batteries, and they come in all sizes, capacity, and price range to keep the device running when the battery icon starts to drop red. And it doesn’t end there. Some power banks are equipped with features such as fast charging, wireless charging, built-in cables, AC adapters, LED flashlights, even the ability to start your car.
With so many options to choose from, how do you know which power bank is right for you? Read on for the most important points to consider.
Size and capacity
Generally speaking, the larger the battery, the greater the capacity and number of ports you get. Power banks that fit comfortably in your pocket are usually good for a full charge of the phone or two, while anything designed to keep you running all day is going to require a bag or purse.
the battery size increases to the point where it’s less likely to fit in your tight jeans, but it can still be stowed in a jacket pocket. There are even batteries that allow you to power laptops and have enough juice to charge the average phone 10 times. Of course, they are some of the largest and heaviest in the group, and they should definitely be carried in a bag.
Input and output ports
The type of port (or ports) a battery has determines not only whether it is compatible with the devices you want to charge, but also the charging speed. At a minimum, most battery packs will have a standard USB-A port for input and output. But with more phones, tablets and laptops adopting the USB-C standard, you will often find a USB – C port in addition to USB-A.
USB-C allows you to charge faster, consolidates input / output into one port and can be found on many new phones. Now, you have to be careful, because while some power banks have USB-C input, they do not have USB-C output.
Lightning is a patented technology from Apple and it used to be difficult to find power banks with a Lightning cable or a charging port. Fortunately, those days are over and there are dozens of excellent power banks made with iPhone users in mind.
Another factor to consider is how quickly a power bank can charge your phone. Battery output is measured in voltage and amperage. Amperage (or current) is the amount of electricity flowing from the battery to the connected device, while voltage is the amount of potential energy. Multiplication of volts by amps gives you power, the measure of total power. To make a device charge faster, most manufacturers vary the voltage or increase the amperage to increase the total power. For faster charging, you are looking to dynamically increase or vary the voltage.
#Essentially, for any type of fast charging you need three things: a phone or other device with a charging circuit capable of using one of the fast charging standards, along with a battery and cable that support the same standard. If any of these three things are missing, it won’t load as fast as it can.
Fast charging, on the other hand, works by increasing voltage rather than amperage. These standard allows you to charge compatible phones to 50 percent capacity in 30 minutes, which is especially useful when you need power in a hurry.
Pass – through and wireless charging
There are a couple of other aspects to consider before selecting a backup battery. Step charging allows you to charge devices connected to the battery, while the battery itself is also charging. If both the phone and the backup battery are running idle, this is a very useful feature.
Wireless charging has also become very popular, as it allows you to turn on compatible devices without the need for a cable, but simply by resting them on the battery. Qi is the dominant standard you’ll find on compatible Apple and Samsung phones, and there are a few battery packs that support it.
Should you buy a battery box instead?
If you find that you often forget to carry your backup battery when you need it most, you might want to think about using a dedicated battery box instead. It combines the portability and protection of a case with a built-in power cell to keep your phone topped up at all times. The downside is that they often have lower charging capacities than dedicated batteries, and you can’t really charge anything else with them.
What should you look for?
Is the brand reliable?A reputable brand is more likely to last through countless charging cycles. We highly recommend, but there are tons of other great brands. We make sure that every option on this list balances price, quality and reputation.
What ports do you have?Most new third-party chargers come with USB-C ports, and you’re likely to get the fastest possible charging with these. However, you will already have a charging cable. .
How many ports do you need?Are you looking to recharge multiple devices with a single charger? The more ports the charger has, the heavier and less portable it becomes. A multi-port charger is ideal on a desk, but smaller single-port or two-port chargers are the best travel companions.
How fast will it load?Fast charging is a standard feature at this point, albeit with varying degrees of capacity. A third-party charger is unlikely to offer the same speeds as patented charging .
What size do you need?You will also have to consider the size. Want something that can easily slip inside your pocket or backpack? Or do you want the most charging power enclosed in a big brick? Are you looking for something that sits on a desk? How long should the charging and plug cables last?
Most wall chargers will work with many smartphones. However, with various charging speeds, ports, and features available on different phones, compatibility is something you’ll have to look into.
Here, we’ll look for the best wall chargers you can get for some of the newest phones available. Something to keep in mind is that while we mention specific smartphones, these can be great options for other phones as well. If you own one of the specified devices, rest assured that the Chargers we have chosen will give you the fastest speeds and the best security.
While we wait for smartphone manufacturers to develop phones that can go beyond a day of reasonably intense use, the short-term solution is to invest in a portable charger, a USB block that you can plug into your phone to get two or three times more use.
These power bank packs are getting smaller, smarter, and can charge faster, and here we introduce you to the best portable chargers of 2019. Do not buy anything before you have reviewed our list and worked out exactly what you will need.
The size and cost increases as well. The second feature to keep in mind is how many USB ports you have, reflecting how many devices you can charge at a time, one might be fine for most of you, but it’s another thing to keep in mind.
