Power banks, or portable chargers, are basically an extra store of juice for your battery. Rather than needing to plug your phone into a wall charger, instead, you can plug it into a power bank and fill the battery that way.
This Gentlemen's Hardware power bank is good looking and has a huge 10000mAh capacity, which means it carries enough to charge to big battery phones or two full charges to an average smartphone. Perfect for on-the-go tradesmen, or people traveling, shopping, boating, tramping, camping and who do not access to a plug.
Plug this power bank in and wait for it to be fully charged. The blue lights on the side will tell you how much capacity it has. You can then use this power to charge up a mobile phone or tablet.
This compact but powerful unit has 2 USB charging ports and comes with a USB to Micro USB charging cable.
A great gift for those that like to go off the beaten track, go to festivals and those that need to charge up their phone on the run.
