Firstly, you can charge your portable charger via direct current recharge i.e. through USB input port; this port is compulsory and you will find in every power bank you want to buy. Secondly, is the car USB input; this facility allows you to recharge your power bank, meanwhile, driving towards your destiny, it ultimately saves your time. Thirdly, recharge power bank through sunlight via separate solar panel or in some power banks you will find its own panels, however, this mode is for the emergency purpose, in case, when neither there is a direct source of current nor you have the facility to recharge via a car battery. Battery remainder The portable charger you buy, it should have LED flashlights or OLED screen to keep you updated of remaining battery status. This feature is known as real-time power management, in which it will show how much battery is taking power from the socket via power adaptor and how much it is discharging when another device is connected (mobile phone etc). In some cases, OLED screen shows only the incoming power status while recharge and not the outgoing power status, when put into use. Qualcomm Quick charge It is a fast charging technology found in your daily used devices, for instance, mobile phones, power banks, rechargeable cameras, fans and other rechargeable devices. However, when we particularly talk about the power banks, this technology enables your device to charge faster than its standard capacity of charging with its specific USB cable. In this way, it will charge your device in less time than the expected duration of the full charge and support better and effective performance of the device in the long run. Whereas, Qualcomm quick charge version 1.0, 2.0, 3.0, so on, supports 5V with max 2A max 10W, then 5V, 9V, 12V with max 3A, 2A or 1.67A 18W and 3.6V to 20V with 2.6A or 4.6A 18W, respectively. Pass-through charging technology Pass-through charging technology enables the portable charger to refill or recharge itself from the wall charger via input outlet, whilst charging the devices (mobile phones, tablets, cameras, drones etc) from the other end. In contrast to this feature, there is a major disadvantage as well, that is, it might cause damage and deteriorate your battery cells and the device you want to charge too. This is because of the difference of the power the portable charger is taking directly to be recharged from the wall socket and the power it is giving (discharging) to your device, ultimately reduces the lifespan of both the devices. But if this facility is rarely used, probably in extreme need, then it might not cause any serious damage to the devices iSmart Technology This property is also called auto detect IC technology. Its function is to recognize the requirement of the current by the connected device. It is an automatic procedure, in which when the device is detected, this technology helps to deliver only that much amount of power to the device, which it can take easily without harming its battery cells. Whereas, this technology is purely different from the Qualcomm quick charge and it can not play its role either in its absence. Flight Compatible What use of a power bank if it is not allowed on the flight? If you love to travel and often use your phone or laptop on the plane, then your portable charger should be eligible to step on the flight along with you. But that is not the case every time remember because a certain amount of wh (watt-hour) of the power bank is prohibited by the FAA (Federal Aviation Association). Since the limit is 100wh or in some Airlines they allowed power banks not more than 160wh, you can bring only less than this capacity. How to check the wh (watt-hour)? Here is the method to calculate it; mah/1000*V=wh Battery Type There are two types of battery cells; lithium polymer and lithium ion. Whereas, lithium polymer battery is the best to store the energy in an effective way and can store a quite huge amount of power as compared to the lithium-ion battery capacity.

Charging pads or charging stands are the new technology and the most innovative way of boosting your smartphones, however, this way of charging is only for the devices with the Qi enability, like the iPhone series with Qi technology. In this process, there is an electromagnetic induction between the surface (induction coil) of the charger and the receiver (induction coil) at the back of your smartphone that fed directly into your phone battery. How to charge a Power bank Step 1. The power bank charger you buy comes along with its accessories. In which you will find a USB cable and an adaptor to recharge it. You simply need to plug the big jack of the USB cable in the adaptor and small jack in the USB port of your portable charger, named; DC/input. Step 2. Now just plug the adaptor on the wall socket and leave it till all the lights lit up on the head of the power bank (better to see the manual for the estimated charging time of the device). Note: Don’t ever leave your portable charger too long to recharge on the socket, it will damage the battery and shorten the lifespan of your power bank. Step 3. Unplug the USB cable from the power bank and adaptor from the socket. It is ready to use. Wink * Note: you can charge your power bank portable charger through your laptop instead of the wall socket or car USB port, in the same way, minus the role of the adaptor.

Our Verdict

From draining to dead batteries to preoccupied sockets and wall chargers, the best portable chargers are the only solution to these. It not only allows the user to move freely without leaving their phones, laptops and iPads behind to get charged, but also ensures the safe and reliable boost remaining close to us. However, not every power bank or portable charger is built to recharge your phone or laptop, but the type of this varies according to the capabilities so do the power of that external battery pack. For instance, any power bank for smartphones does not necessarily be able to charge your laptop. Similarly, a portable charger with 10,000mah wouldn’t be able to charge your laptop. Hence, the specifications must be taken under consideration before buying any, and your need and usage must also be specified. In the same way, your interest and future demands should also be checked, like in a situation where you can not only charge your phone, laptops and tablet, but also other electronic gadgets too. Which is most likely your portable fan, water dispenser, lamps and other small devices including GPS devices, cameras, earphones, drone etc. Moreover, if you have not yet experience the solar panel chargers and always sooner or later found your power bank runs out of battery as well when you are traveling for days, then nothing could be better than solar portable chargers.
