There are two main forms of lifetime that are associated with Power Banks.
•Charge discharge cycles: Any rechargeable battery will gradually wear out. Normally the lifetime of a battery is quoted in terms of the number of charge discharge cycles it can undergo before its performance falls by a given degree. Some cheaper Power Banks may only have a life of 500 or so charge discharge cycles, but better ones will have lifetimes of many more charge discharge cycles.
•Self-discharge time: All battery cells, whether rechargeable or primary have a certain level of self-discharge. For rechargeable batteries these days with their own control circuitry, a small amount of power is required to keep these circuits alive. As a result, there is only a finite time that a battery will remain charged.
A good Power Bank can hold a charge for up to 6 months with only a small loss of charge, but lower quality ones may only retain a useful charge for about a month. These figures are for room temperature, but storing them outside these temperatures considerably reduces their performance.
While some tablets can accept lower input (1A or 1.5A), the charging is slower and sometimes can only be charged when the tablet is in sleep mode. So, before you throw a fit, here are some things you might want to consider:
o It might be about the cable and not the charger. Get the cable changed and try again. o Make sure the battery provides 2 amp and above. A 3 amp mobile charger ideally does the trick. o There might be a compatibility issue: For e.g.: Samsung Tab might need you to use the designated cable and connector.
Various shapes and sizes and sizes are available in Power Banks. Some are useful as a car mobile charger, some as bike mobile charger. Follow the instructions at your own risk. The guidelines have been taken from instructibles.com. The same device will not work for iPhone.
