Not all power bank manufacturers are equals when it comes to design. iWalk is an improvement in this regard. The power bank won't let you down in terms of functionalities either. The power bank comes with a micro USB cable that can be used with almost all other devices. Still need another cable? No problem. There's an extra USB port and USB-C port. The LED screen shows you the most important information, like how much energy the power bank still has. You can fully charge the average smartphone up to 5 times, or a 12-inch MacBook twice. This will keep you going for a while.
Note! With this power bank, you can only use a USB-C connection to charge laptops.
