Criteria Used for Evaluation
This has to be one of the top criteria to keep in mind when looking to use a power bank. Capacity here refers to the number of times the power bank will charge the phone for you. A full charge is known as a cycle. If you are working in or traveling to a remote location where there is limited access to charging points, then obviously you will need a portable charger with a higher “mAh” (more on this in the FAQs section). In other words, you will need a power bank which will give you many recharges when fully charged as opposed to just 1 or 2.
At this point, you may be forgiven for asking why should you just not blindly go for the one with the highest capacity as more is obviously better, right?! Well, yes and no. Being able to recharge more often is obviously a plus, but it comes with a trade-off or two. Usually, the power banks with the highest charging capacities tend to be the most expensive. Therefore, if you seek a portable charger that has above average charging capacity, be prepared to shell out a few extra dollars. High capacity power banks also tend to be bigger in size and heavier than their counterparts with lower capacity and that should also be factored in. This becomes particularly important if you plan to carry it around with you all the time.
In this case, obviously, the power bank that takes the least amount of time to get fully charged is most preferable. Whether you are using it on an airplane on a holiday or using it just before work in the comfort of your house, the faster your power bank recharges the better it is for you.
Regardless of your plan to use your power bank, it would be in your best interests to get one that it is not too big. Compactness is key when it comes to power banks as it is possible or even likely that you will be carrying it around with you a lot. A few extra inches may not seem like much in isolation, but at the end of a long and tiring backpacking trip, it all adds up; trust me!
Another issue with a power bank that is bigger than average is that it makes it difficult to stash it away in your pockets. Tight and uncomfortable pockets do not make for pleasant experiences, whether you are on a hike or at a party. If it is too big for your pockets you will probably have to put it away in a bag. This will take up precious space in your travel or work bag that could have been used for something else. In a nutshell, the smaller and more compact it is, the better.
This goes hand in hand with size. Your ideal power bank should be as light as possible. While a few extra ounces may not seem like much, just like with size it all adds up at the end of a tiring day or a long hike or something similar. As with virtually everything in life, there is a trade-off though. The heavier ones are usually more sturdy and durable. This makes them less vulnerable to damage if they are dropped. Of course, if you drop any power bank enough times it will break or get damaged in some way, but the key takeaway here is that the heavier ones are more damage resistant. Therefore, if you are someone who tends to drop things a lot or rough handle your possessions, then it might be safer and wiser to invest in a power bank that is more durable and stronger.
Overall when looking for a power bank for your electronics, first figure out where you will be using it mainly. Will it be the office, on the bus, on your next hiking trip, etc. Once you know where you will be using it, then you can determine the size and weight of the power bank you will need.
All good power banks are thoroughly examined for defects before they are introduced into the market. However, due to the very nature of power banks, there is the odd defective piece from time to time. Not only that, sometimes the defect takes a while to develop and is only apparent from considerable usage. This is where a warranty comes in.
When you buy a power bank, look for at least a 1-year warranty, preferably an 18 month or a 2-year warranty. Inherent flaws and defects in the power bank may take a while to develop. It would be a shame if you were deprived of your right to exchange only because of lack of warranty/expiration of warranty despite it being no fault of your own. One crucial point here is that the warranty is usually limited to manufacturing or production defects. Therefore, if the charging cable is too small and you use it to transfer more electricity than it can handle resulting in it malfunctioning, then it would not qualify for a free repair or replacement even if it happens to be under the period of warranty.
Some power banks also come with a 30-day money back guarantee or something similar wherein you can return the power bank within the stipulated period if it does not meet your expectations; obviously this is subject to a few terms and conditions. Good customer service is always welcome and essential to being able to claim your warranty. Make sure that the company whose power bank you plan to buy has good and professional customer service.
Expert Interviews & Opinions
Faulty power banks are not uncommon. There have been cases where faulty power banks have caused voltage problems, overcharging and overheating issues and even electric shocks. This is why it is imperative that you carefully examine the safety features of the power bank you are interested in buying. A good power bank with adequate built-in safety mechanisms will greatly minimize the aforementioned risks. Therefore, ensure that your power bank has enough safety mechanisms inbuilt to counter potential charging accidents and incidents.
When looking for a power bank, always check the dimensions of the power bank as the picture online may be misleading. Figure out if you would like to store it in your purse or bag and how big of a power bank you can get that will fit and be easy to transport.
Other Factors to Consider
Number of USB Ports
If you are someone with a hold of devices that need to be charged at the same time, then you will need a power bank with more than 1 USB port. Typically power banks come with dual USB ports. The bigger power banks have more than two USB ports to enable you to recharge 3 or 4 devices at a time. A power bank with that many USB ports will usually be bigger in size, therefore that has to be kept in mind as well.
LED lights to indicate charging level
Most power banks on the market do come with this feature, but there are still a few that do not. Make sure that your power bank has LED lights that indicate how charged a power bank is and how much charge it has left before it gives up on you. The last thing you want is for you to mistakenly assume that your power bank is fully charged only for it to give up on you at the wrong time. Sometimes the power banks with LED lights also come up flashlights which can definitely come in handy especially when you are on the move.
Frequently Asked Questions
q: What is mAh and what is its relevance?
A milliampere is abbreviated to mAh. It indicates the capacity of the battery to hold a charge. A power bank with 20000 mAh has more capacity than a power bank with 10000 mAh, a power bank with 10000 mAh has more capacity than a power bank with 3000 mAh and so on.
q: How many times can I charge my smartphone using the power bank?
This depends on the capacity of the power bank you have and the device you intend to charge. For example, if the power bank you own has a capacity of 12000 mAh and the device you want to charge has a battery capacity of 2000 mAh, then your phone can be charged 6 times using the power bank (12000/2000).
However, there is an important point that needs mentioning here. In the aforementioned example, your phone can only be recharged 6 times in theory. In reality, it is unlikely to be able to charge your phone more than 5 times because there is some energy/charge that is lost during the whole charging process, which means full efficiency is not reached.
q: Can you charge tablets, Ipads or laptops using power banks?
Yes, absolutely. You will find that your power bank works just as well for these devices as it does for your smartphone. However, tablets, Ipads, and laptops typically have much longer battery spans than a smartphone. Hence, even a 20000 mAh power bank may only give you two recharges at most.
q: What does the output specification mean?
1A-1.5A is usually for smartphones. On the other hand, 2A is generally for tablets.
q: There is no cable to charge your phone or tablet. Is that normal?
Yes, this may or may not be normal depending on the specifics of your power bank. Make sure to check thoroughly the box of the power bank you intend to buy. If the list of contents makes no mention of such cable then you will not get it. Please note that this is different from the cable that is used to charge the power bank, which you will most certainly get regardless of which power bank you choose.
