Alex Varga Antonius Fast Charge 20W Power Bank - 10,000mAh

a fully charged 10,000mah power bank should charge an iphone 2 – 3 times from zero to full charge, before needing to be recharged itself. It should charge most modern android phones 1.5 – 2 times from zero to full charge. This 22.5w power bank can charge your phone faster than a standard 10w power bank. 
The compact design gives you the chance to carry some decent power with you, which doesn’t take up too much space in your bag. It has a matte, textured surface, with a smooth space to brand your company logo or message, finished off with shiny gun metal trims. The §§led§§ display will help you keep track of how much power is remaining in your power bank.
