Power Bank FAQs

What is a power bank?

A Power Bank is an extra battery or simply an external and portable charger for your phone or any other chargeable device. It is a power source made of a rechargeable battery, packed in a small and handy case that is easy to carry around. It has at least one port for charging and another for charging your devices such as tablets, smartphones, laptops, etc. Both its ports connect to a standard USB cable for charging.

How do they work?

Power banks are very convenient and easy to use. They are just small cases that will plug in your device and start charging it. Charge your power bank before using it; the LED lights will show the charge status. Once the battery is full, plug in your device using any USB cable, and it will start charging your selected device. So, zero hassle and incredibly easy to use.

How do I charge a power bank?

You can charge the power bank just like you would charge any other device. You can use the USB cable you get with the power bank. It is usually a micro USB or USB Type-A cable. Connect this cable to your available charger and plug it into a socket. The power bank will start charging immediately. Power banks usually come equipped with a Lithium-Ion battery, but many power banks now are made with a Li-Po battery (Lithium-Polymer). These batteries are more compact; thus, making them even more portable and lighter in weight. Hence, they are generally preferred more.

How fast can a power bank be fully charged?

Due to the high battery capacity of power banks, it can take some time before charging 100%. Another vital factor is the power outlet used for charging your power bank and the power output that your selected adapter has. Most phone chargers have an output current of 1A. The adapters of tablets come with an output between 2A to 2.4A. So, if you were to charge your power bank using a tablet adapter and corresponding cable, it would take a relatively shorter time than with a phone adapter or an adapter with a power output of less than 2A. The best thing is to avoid the USB ports of laptops and computers as they only give 0.5 to 0.9A, and they can slow down the charging considerably.

What does the mAh capacity on the power bank mean?

A power bank will have its capacity in mAh (known as milliamp hours). It is a measurement standard used for the power or total charge stored inside the power bank. So, in general, the higher the amount of mAh capacity shown, the more the number of times you can charge your device before the power bank needs recharging.

Is it safe if I charge my device from a power bank multiples times a day?

Our power banks ensure the complete safety of your device. We carry out thorough safety checks on all our products; you can check out all our safety certifications on our Certificates page. All safety certificates for each model are also available on separate Product Pages.

Some of these safety features include:

  • Strong body encased in a pack that protects the battery from falls or hits.
  • Batteries of the highest quality only from leading brands.
  • Input and Output over-voltage and over-current protection.
  • Shut down in case of high temperature recorded.
  • ESD (Electrostatic Discharge) protection.
  • Short circuit safety.

How long will my power bank take to charge?

As mentioned before, it will all depend on what capacity (in mAh) your power bank has. You can see the LED light display to check how much the power bank has charged or how much battery is available for use.

What is the life of a power bank?

If your power bank is in good condition, there is no reason it won’t last for a couple of years. However, if your power bank is in use multiple times a day, the battery performance will eventually decrease, like other batteries.

How do I know which power bank will suit my device?

Selecting a power bank depends on your requirements and needs. There is a whole general criterion to consider when choosing to buy a suitable power bank:

a) Capacity

For example, if your phone’s capacity is 1500 mAh, a power bank with a capacity of 2200 mAh can charge your phone fully once. But if your phone battery’s capacity is 3000 mAh, then the same power bank won’t charge your phone fully because the phone’s capacity is higher. So, if you are looking for a power bank that can charge your phone several times a day, then look for the power banks with high capacities.

b) Output ports on the power bank

Each power output will charge one device, so if you need to charge more than one device together, you will need to get a power bank with two or more outputs.

c) Output specification for your devices

1A-1.5A output is for smartphones, whereas the 1.5A-2.0A output is for tablets.

I can’t turn on my power bank. What do I do? 

It can be because:

a) Your power bank is totally dead, and it doesn’t have any charging left. Charge your power bank, and the indicator (LED Light) will start blinking once it has enough charging.

b) Your power bank has gone into sleep mode.
The power bank can automatically stop its power and activate sleep mode if it detects a short circuit, over-discharge, or overcharging. It can happen due to a faulty cable. To fix this, charge the power bank with its 3-pin plug and use a good quality cable with no issues.

Is it true that a branded power bank has less danger of exploding than a generic power bank? 

Any device with a battery has a chance of explosion, mainly in the case of overheating. It does not matter whether your power bank is branded or generic because the odds of any of them exploding are near 0%. So, don’t worry, and keep your device and power bank away from conditions that are not favorable.

Are power banks good for promotion?

The good news is yes! One of the main benefits of power banks is that they get used daily, and many people out there have power banks that don’t fulfill their requirements. Power banks get used almost daily to charge our phones, tablets, and other devices that we take everywhere with us. All of this makes a small and portable power bank that much a commodity. Now, imagine your logo on your power bank that provides the best quality. Customers and clients will make sure to always remember the great service from you.

Tips for maintaining a long life

  • Never keep your power bank empty and charge it.
  • At minimal use, it’s best to charge your power bank once every three months.
  • Use the cables provided originally for charging any device.
  • Store it whenever it’s not in use. Place it away from hot and humid places, and don’t leave it out in the sun. The recommended temperature would be 16 to 22 degrees.

General Information

  • A = Ampere
  • mAh = milliampere-hour
  • The Output of PC’s USB port: about 500 mAh
  • The Output from wall 3-pin plug: varies (please check wall socket’s specification)

Laptop Battery FAQs

How long will a battery last before I need to replace it?

Any battery will eventually slow down and degrade with time and as you use it more. For the average person, a battery will last two years, but if your laptop is in heavy use, chances are you might need to replace it sooner than that. We recommend using certified batteries or batteries from the same manufacturer to avoid any problems.

What does it mean by 6 or 12 cell batteries?

These indicate the running time. 6-cell batteries might last for an average of 1 ½ hour, whereas a battery with 12 cells can last up to four hours. If you are on the go a lot, it’s best to invest in a large cell battery; however, it may add some weight which can vary from brand to brand. Cell size can also give you an idea about how long it will take your battery to charge.

Even when my laptop finishes charging, I don’t unplug it. Can this overcharge it or harm it?

Most laptop chargers have an option that detects if the battery is full and so will stop charging. If you see that your battery keeps charging and doesn’t stop when plugged in, you might need to get a new adapter or battery.

If I drain my whole battery and then recharge it, does that prolong its life?

No, this will not increase the battery life as they are designed specifically for these situations. Although, do remember no battery runs forever, so it will eventually degrade with time and usage.

When I plug my laptop into the wall, sometimes it starts charging, but other times it doesn’t. What’s the reason?

A full battery only uses alternate current electricity. But if you think that the charging isn’t activated and your battery still drains, then the battery could be the problem. A broken DC jack (the port where your power cable plugs into the laptop) or a failed power supply might be the culprit. If the jack is broken or cracked, you have to get it repaired. A voltmeter easily checks your power supply. The average voltage on plugging in is from 18 to 24 volts. Please seek professional help if you don’t know the workings of a voltmeter.
RCCS will assume no responsibility for any electricity misuse or harm that results from the failed testing.

Can users replace laptop batteries?

Yes, easily. Your laptop has a latch under it that loosens the battery for you to take it out. Remember to shut down the computer and unplug it from any power outlet. As mentioned above, the standard recommendation is to buy the same battery brand or a certified one.
