Like any piece of technology you may use, you can always choose the first one you see, but you’re unlikely to get one that does everything you need it to.
For a power bank, there are a few things that we suggest you look at before you buy.
Measured in milliamp-hour, commonly known as “mAh” is important to consider because it tells you how much power it will use to charge your tech and also how often you may need to charge it. It can be common to see capacities ranging from 2,000mAh to 15,000mAh, some power banks on the market have a capacity of 40,000mAh.
The higher the capacity, the more times use can use it to charge your device. While many people will use a power bank to charge more than one device, knowing how many devices you plan on charging with the device will help you pick a capacity
A power bank is meant to be a device that is easily portable so that when you’re on the go, you can plug your device in, put the device in your bag or pocket and go. If your power bank is larger than your phone, you may want to consider a new one. The physical size of the power bank does not affect the capacity that it comes with.
It is pretty simple, the more ports a power bank has, the more devices it can charge at the same time. Typically though, the number of ports that a bank has will increase the physical size of the device. If you’re looking for one you can put in your pocket, it may only come with one of two ports.
Out of what you should consider, the voltage has to be one of the most important and that’s because of the potential safety risk. You don’t want to buy a power bank that has a voltage higher than the battery of the device you’re charging.
This is because if the power bank has a higher voltage, it can cause your device’s battery to swell and possibly explode. If the voltage is less than the battery, it may not charge the device at all. Always check compatibility.
It always comes down to price as a consideration when you choose what to buy. With power banks ranging from $24 to $199, finding something within your budget shouldn’t be too difficult. Cheaper is not always better and you do get what you pay for, so making sure it has what you need is important.
