How do I know if my power bank is safe?


Among the most practical modern devices is a power bank. When your iPhone or Nintendo Switch is about to die, connect it to a power bank and it will begin charging immediately.

Having said that, finding the right power bank is not as straightforward as it appears. If you bought one and are disappointed with it, we think you overlooked a few critical factors.

And in this article, we’ll show you some of the critical things to look out for before getting a powerbank.

How do I choose a power bank for my phone?

When buying a power bank, you should consider the brand, customer service, and capacity of the power bank, along with other things.

In this article, we'll look over ten things you should look for when choosing a power bank. So, let's get this ball rolling.

10 Must-Have Features for YOUR Powerbank

Powerbanks have different features and charging abilities that you need to pay attention to. Some powerbanks can even explode.

This mostly happens when you do not pay attention to things like capacity, outage, input, of your powerbanks before purchasing.

Let’s go over ten (10) basic things to look at when getting a powerbank for your mobile devices.

10 tips for buying a power bank today:

1. Check the Power Bank Charging Capacity (mAH)

The first thing to check is your power bank charging capacity - this is measured in mAH!

Does a 5000mAh power bank guarantee two complete battery charge cycles for a phone with a 2500mAh battery? Regrettably, despite how much we'd want the answer to be yes, it isn't.

For smartphones, the power rating is set at 5 volts. Power banks, on the other hand, have a power rating of 3.7 volts since they include Li-ion (Lithium-Ion) cells. And this discrepancy results in a decrease in charge cycles.

How can I check my mobile power bank capacity?

Luckily, there is a way to estimate how many times a power bank can charge based on its capacity.

Consider the 5000mAh power bank once again.

How many full charge is 5000mah power bank?

In this case, the total energy is 5000mAh x 3.7V = 18500mWh. Now we need to convert the capacity at 5V to 18500mWH / 5V = 3700mAh.

It doesn't end there though. You still need to consider other factors like heat loss, resistance, and the product's degeneration over time.

2. Power Bank Battery Quality

What are the qualities of a good power bank?

How many watts is best for a power bank?

How long can a power bank hold its charge? It's difficult to pinpoint the specifics, though one thing is certain: it won't last forever. At best, you'll get 3-6 months, and only if you use a high-quality power bank. Unfortunately, with lower-grade power banks, the number only lasts a month.

The disadvantage is that these figures are subject to change. The capacity of a power bank to keep charge is affected by various factors, and it deteriorates with time.

For instance, if you do not charge it on a regular basis or if you leave it in an area where temperature fluctuations are way too frequent.

3. Power Bank Warranty and Support

Does your power bank provider give warranty and support?

You want to think about things like warranty coverage for the power bank. You should also look at the customer service ratings for that firm.

Consider our Cyberpowerbank 4000mAh Portable Charger. Many people have praised our product's exceptional service in their reviews.

We at Cyberbackpack believe that a customer’s satisfaction takes precedence over everything. We are always fast to respond to any complaints!

4. Power Bank LED

The LED is the lights we see on our power banks.

What do the lights mean on a power bank?

Normally ignored, a power indicator is a useful feature. Power banks lose power over time, and if you are not diligent with charging and charging cycles, you may frequently have to scrape up a dead power bank. If you don't have a lot of time to juice it up, you can find yourself in a pickle.

That's where the power indicators come in. This handy little feature, generally in the shape of small LED lights, informs you of the product's residual energy.

A few devices need to be shaken to identify their reserve charge. In others, there is a little button to turn on these indicators. Whatever the situation may be, make certain that the product you are purchasing includes these useful LEDs.

5. Power Bank Charging Speed

How fast can a power bank charge?

Imagine carefully planning for a vacation only to discover that the power bank you brought as a backup takes an eternity to charge. Bummer? It'd be a headache on long trips (or at summer camps) if there aren't enough power backup choices.

Portable power banks, especially those with larger capacities, might take a long time to recharge. A respectable capacity device with roughly 20000mAh capacity, on the other hand, should not take more than 6-7 hours to recharge.

The better option is to hunt for devices that have a Quick Charge input for recharging the power back up. Your power bank will be fully charged in a relatively short amount of time because of that.

6. Power Bank QC

What is QC in powerbank?

QC simply means Quick Charge and some power banks have this capacity (like the Cyberpowerbank).

Thus, is your phone Quick Charge compatible? If that is the case, never settle for a power bank that charges at a slower rate.

Most power banks only feature one Quick Charge (QC) port, rather than all of them. As a result, it only makes sense to examine the capacity of all ports.

Again, if one of the ports has QC support (ideally QC 4.0 or 3.0), but the others are at 1A, things become problematic. The best bet is to go for devices that have a combination of 2.4A, 5A, or the QC sign.

7. Power Bank Charging Cable

What cable do I need to charge a power bank?

Don't forget the cables when getting a power bank. Not all power banks are made equal, and not every power bank includes leads. Either for charging gadgets or for charging the power bank itself.

Budget power banks, in particular, may not come with cables, assuming that you either already have your own, or they expect you to purchase one yourself.

8. Power Bank Size And Weight

How much do power banks weigh?

Size and weight are crucial factors to consider when purchasing a power bank, especially if you want to use it while traveling.

We agree that high-capacity power banks are a little heavier. But ultimately, you wouldn't want to carry anything that makes your bag weigh down and hurt your back. Or something that is difficult to tuck in your pockets.

9. Power Bank Ports 

What is the input and output port in the power bank?

The input refers to charging while output refers to the process of charging devices with the power bank. Now, the ports that come with power banks defer.

Early power banks only featured a single output. But as consumers use them more and desire to charge numerous devices at once, many of the bigger power banks now include two or more ports.

Just make sure that the output capabilities for every port are acceptable.

Keep in mind that if numerous devices are charging at the same time, the power bank will not provide the maximum current to each port; instead, an aggregate maximum current output may be split across the outputs, slowing down charging.

Their output is almost always a USB Type A -– the large USB connector used to connect with USB chargers, flash memory drives, and other devices – though the connector used to recharge the power bank itself is different.

It is a micro-USB connector, and occasionally a mini-USB connector, but some have lately integrated a lightning connector so that it can be charged by an Apple charger with an Apple lead, minimizing the number of different cables required.

More recent power banks also come with a USB Type-C port. Our Cyberpowerbank has one too.

10. Brand Integrity

What is brand integrity?

Brand integrity is all about how people see or perceive a brand or business.

Do you have enough faith in the brand? 

That is a question we should address before buying anything, let it be a phone or a portable power bank. At times, even lesser-known brands sell the finest devices, while at other times, even the largest brands produce sub-par products.

A quick look at the brand's reviews area will save you a lot of headaches.

If you are purchasing these products online, take the time to read the seller's comments and ratings. There have been several situations where the brand name matches. However, the goods are quite the opposite.
