These days it makes no difference how cool your Smartphone is when that battery alert comes on it is going to power or it will die and be totally useless until it is able to be plugged into the mains power. However there are some emergency battery chargers available, yet these seem to bulky and awkward to carry around while using the Smartphone. What is needed here is something that is light and practical, something like the ChargeGenie charger! These chargers are like cases as it fixes to the back of the Smartphone and connects through the normal connection. Sure fixing the charger to the back of the Smartphone is not perfect, but it does the job of charging the Smartphone battery without being too awkward.
This is what you can expect from the ChargeGenie, it has a built in lithium polymer battery pack has a capacity of 2100 mAh there is a micro USB connection available or it can connect through a standard Apple lightning connector. The power in & power out is set at 5V, 1A, the typical input charging time is around two hours and it offers protection from short circuit and overcharge or discharge. The ChargeGenie for Android or Windows powered Smartphone’s is expected to go on sale this summer with retail price of £30, however if you cannot wait then it can be pre ordered from just £19 and that is a great saving.
