Buying Guide for best power bank

When it comes to charging on the go, power banks are an easy and convenient way to do so. Power banks come in a variety of shapes, sizes, and capacities which makes finding the right one for your needs a bit daunting. To make things easier for you, here is a buying guide with all the essential criteria you should consider when looking to buy a reliable power bank.

Capacity The capacity of power banks is measured in milliampere hours (mAh). Generally speaking, higher mAh means more charge can be stored or transferred from the battery itself. The amount of juice needed will depend on what devices you plan on using it with; if it’s just your smartphone then you won’t need as much as if you were also going to use it with tablets and other larger electronics that require more energy. Look at both how many times each device can be charged by the power bank before needing another recharge and its total overall capacity in order to make sure it’s suitable for your needs.

Size & Weight It goes without saying that portability is key when choosing between different models of power banks; look for ones that are lightweight yet still have enough capacity to fit whatever devices you want them for. If size isn’t an issue then bulkier models may be preferable as they tend to hold more charge than their smaller counterparts – however keep in mind that these may not always be convenient depending on where/how often they will need transporting around! It’s important not just think about practicality but also aesthetics too – certain designs might appeal better than others depending personal taste!

Input & Output Ports The input port should match up with the cord(s) used by your device(s); most common ports include Micro USB or USB-C which may vary across different brands so double check beforehand! For output ports look out for either two or four USB ports (or even wireless outputs!). This allows multiple devices/cables being used simultaneously while saving time due to faster charging speeds per device compared single-port configurations – perfect if there are numerous people needing access at once! Safety Features Be sure any model purchased has built-in safety features such as overcharging protection and short circuit prevention – this ensures against potential damage caused by excessive current flow into connected devices during use or storage respectively. Many modern batteries also feature temperature control systems which help regulate heat levels within themselves thus preventing overheating issues commonly seen older versions leading potentially hazardous explosions/fires etc…

Price & Brand Quality When considering price points bear in mind brand quality too since this usually reflects build quality/durability over time – although sometimes cheaper options can provide decent performance too so don’t immediately discount those based solely off cost alone! As far warranties go most manufacturers offer some form guarantee ranging from 6 months up 2 years depending manufacturer policy – checking out customer reviews online beforehand helps identify good quality products among bad ones easily without having personally invest money into something risky first hand…
