facts you need to know about tower banks what exactly is a power bank before diving into any juicy technical details let's clarify the basics a power bank is a portable device that can supply power from its built-in batteries through a USB port power banks allow you to store electrical energy and then later use it to charge up a mobile device technically a power bank consists of rechargeable lithium ion or lithium polymer batteries installed in a protective casing guided by a printed circuit board to control power low fact number one what does the power bank capacity tell us the milliamp-hour figure tells us the amount of power flow that can be supplied by a certain power bank at a specific voltage in other words the more milliamp-hour the power has the larger the energy is to have your phone's battery fully charged you should have a power bank with more million power than your phone's capacity fact number two what is the lifetime of a power bank the battery is used in power banks and smartphones eventually lose their capacity over time depending on the quality of the controller circuitry and battery cells a good power bank can hold charge for three to six months with minimal loss lower quality power banks may struggle to retain a useful charge more than four to six weeks the bigger the battery is the fewer cycles you will need to charge it and the longer it will last here's a tip to prevent overcharging and overheating whenever possible remove the power bank from charge when it's full or at least avoid leaving it connected long term after it's full when a battery is constantly stored in high heat its capacity will go down a bit quicker than if it's stored in a cooler environment don't put it in the freezer though just store it inside out of the Sun and in a cooler area that will help extend the life and capacity of your battery pack number three how long does it last for the most logical question right we all want to know that damn phone would eventually completely run out of juice it is based on how long a battery will last when power is drunk constantly a typical smartphone battery which is between two thousand two thousand five hundred milliamp hours will power a device drawing 100 million powers for 20 hours the usage time depends on the load or how much current you are drawing from the battery at any given time if you're using a battery to power something more powerful but will obviously last a much shorter time back number four how many times can a power bank charge my device the number of times you can charge your device from a power bank is dependent on three primary factors what device you are charging what is the device doing while it's being charged and the age and current charge of the power bank an iPhone 4 has a 1420 milliamp hour battery while on iPhone 7 plus has a 2915 milliamp hour battery so the iPhone 4 can be charged twice as many times as the iPhone 7 plus since it requires a lot less from the power bank for 100% charge a good rule of thumb is to divide the milliamp hour of the power bank by the milliamp power of the device battery keep in mind that this is never 100% accurate but it will at least give you a rough idea generally the bigger the power bank and the smaller the device you're charging the more girlz you get other factors can also improve or limit the discharge potential of a power bank so look after them and they will work better for longer pack number five what is the fastest way to charge my smartphone some phones may download updates automatically and consume more power when connected to the charger if we really want to save energy when charging from a power bank it is a good idea to keep the phone in flight mode this will allow you to only charge the battery cell only using the basic features of the operating system on your phone if you're watching a movie on your device while you're plugged into the power bank you may drain the power bank but it will appear that your device never charged this is because you were taking the charge out of the device battery as quickly as the power bank charged it if you leave your device on airplane mode and let it charge you will get a lot more charges out of your power bank since the device is not taking much battery charge at all to run while the power bank is charging it up if you found this video useful make sure you give us a big thumbs up leave a comment and don't forget to subscribe
