Choosing the best power bank is a do-or-die choice. Also, it’s not that simple as it may sound. It requires some technical knowledge, awareness and choices. Power banks are not all made equal. The market is flooded with so many different products from different brands. Some of them are good and some of them are low quality that can literally blow your gadgets apart.
The capacity or mAh rating determines how much charge a power bank can hold and also how many times it can charge your smartphone before draining out. To know which capacity is best for you, you need to know your average daily smartphone usage.
For example, if you have 2 smartphones and only use them for calls and texts, that is only about 600 mAh. If you are the gamer type, then the number of hours of gaming will determine how much power is needed.
So, if you’re looking for a power bank that can charge your smartphone once or twice before recharging, then a 2000 mAh power bank will be ideal. If on the other hand you are looking to charge your phone 6 to 10 times before recharging it or more than 2 smartphones at once, then a 10000+ mAh power bank will be sufficient.
Another thing to look out for when buying a high capacity power bank (anything above 2500 mAh) is the speed of charging. Some high capacity mobile chargers tend to take longer in charging your devices due to their inability to distribute enough current into your gadgets thus slowing down the charging process.
For example: An average 5500mAh Power Bank takes up to 10 hours (or more) in fully charging it while an average 10400mAh Power Bank can take up to 14 hours (or more) in fully charging it! So if fast charging is one of your criteria when selecting a power bank then be sure that it has at least 2 Amps of output current and not less like an average 1 Amp output current!
You might think voltage isn’t really important but it really is because most devices will have specific voltage requirements!
For example: If you have an iPhone 5S running on iOS 8 or above, Apple recommends using a 1Amp Charger or higher because anything lower than that may not make full use of its input current resulting in slow charging speed!
Even worse some low quality non-branded low voltage chargers may damage your iPhone due to over voltage input! Make sure what voltage output the charger provides! The most common voltages used by smartphones are 1Amp (iPhone / iPad), 2 Amps (Samsung Galaxy S4 / S5 / Note 3 etc.), and 3Amp (Samsung Galaxy Note 4).
mAh stands for milli-Amp hour which is used to rate or calculate how much charge can be stored in the external battery pack (or portable charger). So basically when you hear about something with 5000mAh capacity, it means it can store 5000mAh of charge (same goes for 7000mAh or 10,000mAh).
Input Voltage is the voltage coming from an electrical outlet. For example, in the United States, the standard voltage is 120V (and in Europe it's usually 220V).
So if you are using an external battery pack or portable charger which comes with an Input Voltage of 120V, then it means that you can charge your external battery pack or portable charger from any electrical outlet with 120V (even if it's a 220V outlet) – just make sure the power adapter that comes with your external battery pack / portable charger fits in the power outlet.
Output Voltage is the voltage coming out of your external battery pack / portable charger when you are charging a device from it.
For example, if you are charging an iPhone 5 and your external battery pack has 5V 2A output (output voltage), then that means your iPhone will be charged at 2A speed (that means fairly quickly).
If your portable charger has a 5V 1A output (output voltage), then this means your iPhone will be charged at 1A speed and will take much longer to charge. So make sure that when you buy a power bank you check its output voltage first, so you know how fast you can charge devices from this power bank.
Current or commonly known as Amps is used to measure how fast your device will be charged from the power bank. The current rating of a power bank tells us how many Amps are flowing through its port to charge our devices.
For example: If two power banks have exactly the same mAh capacity but one has 2 Amp current rating and another has 1 Amp current rating – then obviously we can say that because there's more Amps flowing through one port than another – our device will charge faster from one than another port.
This is difficult to answer this question as it depends on how many devices you want to charge, where you will be using the power bank, what devices you will be charging and whether you will be using the power bank in a car or indoors.
For example, if you are looking for a power bank for camping with your friends or family then 15000 mAh is enough for two days of charging. If however, you are looking for a power bank to keep your phone charged during office hours then 3000-5000 mAh would be enough because most people charge their phones at home at night.
The fastest and recommended way to charge any device is to use an original charger. Your phone came with one charger and it's safe to assume that the manufacturer tested every possible scenario when they designed the device and they have done all the required safety checks.
It's best not to mess around with that. Original chargers are fast and efficient because they usually have smart chips inside them which talk well with your device and therefore deliver more than 90% of the required energy in less than half the time of cheap chargers.
Using original chargers is also safer as many of these third party chargers use really low quality materials which can overheat easily due to which fire incidents do occur from time to time. Quality batteries are also very important as low quality batteries tend to burst open during the charging process from time to time by which they could cause serious injuries or even death.
Most Portable Chargers come with two USB ports so it's safe to assume that they can charge two devices at once provided both ports support the same voltage input levels (5V).
This means that if one port has 1A output capability then the second port should have the same 1A output capabilities too otherwise it won't work.
Most tablets like iPad air 2 require maximum 2A current input so plugging such tablet into 5V/1A port will not harm anything but plugging iPad into 5V/2A port will damage its battery permanently. So keep this in mind while buying portable chargers/power banks for your tablets.
