Some Frequently Asked Questions (FAQs)

If you still have any query about buying power bank in India,  here we have answered some of the frequently asked questions about Power Bank.  Which will further help you in choosing and buying; one of the best power banks in India.

Which Power bank company I should buy a power bank?

You can buy a power bank from any well known and reputed company in India.  We don’t recommend to buy those Chinese duplicate power banks which are easily available in the markets. Stay away from those crappy products and spend a bit more and buy a good quality power bank for your own safety and for your smartphone’s safety.

What is the estimated life of a power bank?

Actually, it depends on the brand, battery type, and usage. In general, a good quality Power Bank should work well for approx 300 to 500 charge cycle. Large capacity Power Banks usually last longer as they are not required to charge them very frequently.

Can I use my power bank to charge the laptop as well?

No not at all,  power banks are made for charging the smartphones and not the laptops. They have a much lower output that may not be sufficient to charge the laptop battery. If you want to power up your laptop, then you need to consider having a different charging device that is compatible with the laptops.

How long does it take to charge a power bank?

It actually depends on the battery capacity of the power bank. These days, a good quality power bank comes with fast charging capacity which can be charged 30% in just half an hour. Again it depends on the brand and the power voltage at a place.

Can a 10000mah power bank charge a smartphone of 3500mah battery three times?

This is one of the very common myth with most people. Power bank battery capacity is the manufacturers rating and you may not get the same output while charging a smartphone and thus a 10000mAh power bank may not charge a phone of 3500mAh battery three times, but yes you can easily charge that a couple of times.

Is it true that some power banks can explode?

This is only true for the low-quality power banks and that is the reason we only recommend you to buy a power bank from a well known and trusted brand.  It may cost you a bit higher but it is good for both, your smartphone safety as well as your own safety.
