Before buying a power bank you should read these 4 important facts
Our whole lives pretty much revolve around our smartphones and laptops. A power bank is therefore a must-have accessory especially, for internet-enabled devices. Despite being a simple-to-use device there are many features to consider while purchasing a power bank. Here is what you need to keep in mind when deciding which power bank to buy.
The Power Capacity Of A Power Bank
- Perhaps the most obvious feature to look for when purchasing a power bank is its battery capacity. Milliampere hours or mAh is the unit used for measuring the battery capacity. The greater the mAh the more power it stores and delivers.
For instance, a portable power bank with a battery capacity of 8400 mAh would store double the energy that a power bank with a 4200 mAh battery. When buying a power bank the more mAh you can get the better it is.
Type Of Charging Ports
- There are two types of ports input and output. Some power banks come with additional ports that allow you to charge multiple devices at the same time. But you need to keep in mind whether or not the total output current of the power bank is sufficient for charging multiple devices simultaneously.
Input ports on the power bank are used for charging the power bank while output ports are used for delivering the charge to your device. Always buy a power bank that suits your device and the cables that you are going to use with it.
- Although USB-A ports are disappearing from laptops all power banks feature at least one USB-A output.
- USB-C is like the recent standard in most new android phones. The good thing about this port is that it can be used either as an input or output port. There’s no risk of plugging the cable upside down because USB-C ports are reversible.
- It is a small USB variant mostly used in smartphones and other portable devices.
- Some models of power banks offer wireless charging options. They let you charge wirelessly by simply placing your phone over the power bank.
Battery Type Of The Power Bank
- The quality and type of battery a power bank contains is another important feature that should be kept in mind while buying a power bank. Power banks vary in prices depending on the type of battery used. For instance, lithium polymer batteries are far more expensive than lithium-ion batteries.
A slight difference exists between lithium-ion, lithium-ion polymer batteries. Lithium-ion polymer batteries use the same technology as lithium-ion batteries but in a more flexible casing. Lithium polymer batteries on the other hand work on a different technology than the other two.
Lithium Polymer Batteries
- Lithium polymer batteries use a microporous polymer or a gel as a substitute for the electrolyte. Whereas, lithium-ion batteries use liquid electrolytes which makes them comparatively cheaper.
Lithium polymer batteries are safer and thinner but they are expensive and may have a lower energy density. They are usually found in the latest models of laptops and electronic cars and are now making their way into power banks as well.
Build Material And Quality
- Purchasing a fragile power bank that is made of inferior material will do you no good. Look for something robust and solid that will withstand the unavoidable drops, knocks, and impacts. Superior quality power banks are made with durable materials such as anodized aluminum carbonate, silicone rubber, and more.
Some of these materials also provide resistance against heat and fire. Power banks with multi-layered shells offer extra protection against falls and impacts.
