Now, as far as power banks are mentioned, I can confidently say, I have seen it all. I have tested solar power banks, used high capacity power banks that can charge computers. I have also seen a power bank that can replace your electricity, converter or power generating set at home. However, I am currently using an ultra-portable mobile power bank with fast charging for my mobile phone. Power banks buying guides is the article that I have dedicated to every reader on this blog to enlighten them on how to choose right when buying a power bank.
What Is A Power Bank?
A power bank is a portable charger for your mobile devices and it is an absolute necessity if you are a frequent traveller. You absolutely need to be able to charge your devices if you want to fully utilize them on a single trip. Cell phones, tablets, etc., all require power after some time and a power outlet is generally not available everywhere you go.
Nowadays, we have mainly user-nonreplaceable batteries. Therefore, buying and carrying spare batteries for every gadget is not a practical option either. (Not to mention the additional expense over time.) So it’s a necessity that you have a portable power bank with which you charge your devices if you don’t want to stay out of touch.
With a power bank, your phone can be charged everywhere you go when you are out of juice. This facility has given us a lot of relief, so now many people take with them a power bank. Every company claims that their power bank can charge the phone in a very short time. In this case, it is important to know what special power should be in a power bank so that when you buy one, you get the best power bank for your device.

Power banks buying guides for all prospective buyers: Things to keep in mind
1.The brand name of the power bank
My very first Power banks buying guides, focus on the name of the power bank you are trying to buy. Some companies are synonymous with quality, dependability and trustworthiness. Such brands include Poweradd(For your regular and solar power banks), Anker for your portable and high capacity quick charging power banks. Anker also sells the regular power banks. EasyAcc is another great company., ZMI(this is the one i am currently using, it is as lights as my phone and not as big) RAVPower(regular and Solar). I recommend you look into those who have been in the game for years when you are shopping for your power bank
2.Price/quality and features
Everyone loves good things. However, no good thing comes easy. I would have gone for Anker 20000mAH quick charge power bank. Sadly, I settled for ZMI due to financial constraints. I have no regrets because my choice is also good. Please don’t buy a power bank with high mAH and a ridiculously cheap price. They will cause you problems. Either they will be missing vital features or the capacity you will get is unreal.
Similarly, the built quality is very important. I once got a power bank which fell off and broke into pieces. Also, the cables got severed from the batteries. You would need a compact design if you want it to last long. In addition, the following features should be looked out for; overcharging/input overvoltage protection, battery over-discharge prevention, shortcircuit, overtemperature, Output overcurrent, Device auto shutoff, battery overcharge and waterproof features(this is very important for solar power banks)
3. Predetermine your usage before buying a power bank-Know the battery capacity of your phone
If you have a mobile phone with a 3000mAH battery, ideally a capacity of 3000mAH can fully charge it once. however, this is not always true. And when you buy a portable power bank, make sure that it can charge the battery for a specific device. By this I mean make sure its output voltage matches with the device you own. This is because if the output voltage of the charger is less than the device being charged, you will have a problem. Of course, the reverse is true, if you have a charge with a larger output voltage than your device, you should be able to get several charges for your device.
Power banks buying guides: how to determine your device’s battery capacity

For all known mobile phones and watches, please visit gsmarena.com and search for your phone. Scroll down and you will see a section similar to what is shown in the image above, there lies your battery capacity.
My Power banks buying guides for devices with a removable battery, please remove your battery and check the writings on it. Also, for all devices that come with a user manual, check the specifications section of your manual and it will there. Finally, for other devices that cannot utilize the steps above, simply visit your device manufacturer’s website and goto the specification of your device.
Should you decide on buying a portable charger, keep your own usage in mind. To be on the safer side get a power bank with a capacity between 8000mAh (and higher mAh) units are also available. There are chargers that can charge almost any type of device, from all types of companies. This includes laptops, iPad, iPod, tablets, and mobile phones from Apple, Samsung and HTC.
