While most casual buyers rely on the battery capacity only, a few minutes of research reveals there’s more to power banks than just how many milliamps the battery is.
This is a device that you'll be carrying around a lot, so durability is just as important as portability.
Most portable phone chargers contain a standard lithium-ion battery pack inside a casing. Cheaper ones, however, have a plastic housing or casing in which the parts are assembled. Plastic parts are prone to heating up or getting damaged when dropped, but chargers enclosed in plastic shells are lighter than metal ones.
Premium chargers are encased in aluminum or other kinds of metal shells, which are tougher, and cannot be damaged easily even if dropped. If portable phone chargers are dropped and damaged, they can be subject to accidental bursting or fires, so drop-protection and toughness should be given priority.
If you're going on an adventure and need something that can withstand outdoor exposure like shock or dust, consider a charger with a rugged design.
A rugged power bank is quite bulky and heavy. However, it's drop-proof, so it's less likely to break when you accidentally drop it on the ground and is useful for outdoor enthusiasts. Intend to visit some ocean side? Search for products that are also waterproof!
There is an easy way to help you determine how much charging power you would need. Simply search for your device's battery capacity, which is measured in milliampere hours (mAh), and choose a portable charger with a capacity that exceeds that number. It'll give you more than a full charge!
Most portable phone chargers nowadays contain a charging capacity of at least 10,000 milliampere hours, which is enough to charge modern smartphones around one and a half times.
This capacity is also great for college students or working professionals who just need a charge on the go but have access to power outlets if the need arises in their colleges or offices.
If you intend to charge multiple devices such as a smartphone, earbuds, or an e-reader at once, you might want to consider a portable charger with a charging power of at least 15,000 milliampere hours.
For emergency purposes, or when going hiking where power outlets are not guaranteed, it is best to carry a charger with around two to three times the battery capacity of your device. To charge your laptops and tablets, go for 20,000 milliampere hours, as the batteries of laptops are usually around 8,000 milliampere hours.
Also, a portable phone charger, regardless of the quality, cannot provide 100 percent of the charging capacity as mentioned by the manufacturer. In fact, a power bank can only provide 65 percent of the advertised capacity since it has to convert its output voltage to match up with the device's voltage before actually charging it.
A portable charger might have a lot of charging capacity, but it might still take a while to charge your phone. To understand how quickly a portable charger can charge your device, you need to understand its output.
Technically, the output of a charger refers to the maximum power that will be provided to the external device and is measured in amperage and voltage. By multiplying both of them, you'll get wattage, which is the measurement used to determine the total power.
To charge the device more quickly, manufacturers will increase either the amperage or the voltage. For example, the majority of modern phones can handle five volts and 2.4 amperes. So, a charger that can boost the voltage up from five volts to nine volts and above or bump the amperage to three amperes and beyond can help charge your phone faster!
However, don't get fast charging unless your phone actually supports it. Smartphones rated to support fast-charging can also be charged via normal chargers, but the reverse is not true, and charging normal smartphones with fast-chargers may damage the internal phone battery.
Care should be taken to ensure that portable phone chargers with fast-charging capacity are only used with smartphones that support fast-charging.
The type of ports a portable charger will decide if it's compatible with your devices or not. Most products should have a USB-A port for input and output. This port type is a connection standard that's frequently found in laptops and desktop computers.
However, nowadays, most modern smartphones, tablets, and laptops are shifting to USB-C type charging, which gives faster charging and hassle-free reversible connectivity. So portable chargers should have at least one USB-C port as well!
If you're using an iPhone, make sure your portable charger has Lightning ports, iPhones' proprietary technology. You want to check how many outputs the charger has as well. Some products allow you to charge one device at a time, while others allow up to five devices!
Some premium portable phone chargers nowadays now support wireless charging, which is present in most high-end flagship smartphones.
Some are designed with a flashlight, a convenient feature for outdoor uses such as camping. There are products with a LED display as well, which shows you how much power is left in the portable charger.
Some portable phone chargers also provide additional features like a built-in cable, two or three charging ports to charge multiple smartphones simultaneously, and even two different types of ports (USB-A and USB-C).
When your charging port is stuffed with dust or debris, it can interfere with your phone getting the juice it needs! If you're experiencing issues with connecting your device, try these tips from Ventev Mobile on how to clean your port.
Active and busy smartphone users won't settle for being tied down! Have a look at these other great items for work and leisure tech you can't live without.
The primary concern when buying a new portable charger is how much capacity the battery has, but while that rating is surely important, each customer also uses the power bank in a different setting.
Do you need one that's rugged, waterproof, and drop-proof? Or are newer technological features like fast charging and reverse charging your priority? Keep our tips in mind when shopping for your portable charger!
