Anyone who has witnessed this knows how demoralizing it is to be separated from your device. This made having a backup source of power a necessity. But with the amount and variety of power banks on the market, finding power banks that are right for you is a huge undertaking.
Here are some tips before you buy a power bank.
I think that's one of the first things to watch out for. I once had a power bank that was three times the size of my phone (an iPhone 5) and weighed as much as it looked. The obvious problem I had was how to put it in my pocket. So many times I had to leave the phone in my pocket and carry my power bank in my hand. It didn't seem like the perfect way to manage my device.
That said, if you travel with a handbag often, size may be less of a concern for you, but you should also be aware that physical size in most cases may have nothing to do with ability or strength. from a power bank. .
Obviously, the number of ports determines how many devices can be charged at the same time. Basically, the more ports, the more devices it can charge simultaneously. Interestingly, this factor sometimes has an effect on the size. So if you want a power bank that fits perfectly in your pocket, you might be looking for one with only one or two ports.
With the increasing number of portable devices ranging from MP3 devices, Bluetooth devices, phones, tablets and iPads, sometimes it is more efficient to acquire a gazebo bank with plenty of ports so that whatever your needs , you are sure to have all your devices accounted for.
When looking for a power bank, consider the voltage of the utmost importance because, unlike other factors, it can present a safety risk. The rule is quite simple:do not buy an external battery with a higher voltage than your battery. So, for example, a 5.5V power bank for a 3.7V battery may not be the best choice.
Indeed, if you charge your battery with a power bank that has a higher voltage, it starts to swell and may even explode. Also, if you charge your battery with a lower voltage power bank, it may never charge.
Capacity measured in milliamp-hours, or "mAh", is a key factor in how much energy it will use to charge your device and how often you will need to charge it.
Common nominal capacities are 2,000 mAh to 15,000 mAh, and in some cases up to 40,000 mAh. The higher the power, the more it can charge your device. While looking for a power bank, you need to consider how many devices you have and invariably the capacity needed to fully charge your devices.
It is almost always the factor that determines which of the other factors will be considered. With prices ranging from $4 to $100, you'll likely find something within your budget. I will generally recommend one towards the top of your budget, as cheaper isn't always better, and often what you pay for is what you get.
This, of course, is not an exhaustive list, but it is a very good starting point when looking for a power bank.
