I've been a big fan of Anker since I first started using their products a couple of years ago.

My main devices — the iPad Pro, iPhone, and MacBook Pro — wouldn't be as powerful or useful to me without their accessories. 

Anker is currently holding a 20% off sale on many of their tech accessories, so I rounded up the most useful ones for you, below. 

A high-capacity external battery

I always find ways to recommend an external USB battery; it's by far the most useful accessory you can buy for a mobile device. 

This is one of the highest-capacity batteries than Anker sells — it can recharge the latest iPhone 7 times — and at this price it's a no-brainer. The other big benefit of picking up this battery over some of the smaller-capacity models is that you can charge two devices at once.

A USB-C battery

This is the same battery I just recommended, but this one has a USB-C port. 

That might not be important to most of us right now, but as USB-C adoption grows, it'll turn into a must-have feature. As it stands now, you can use this battery to extend the life of Apple's new MacBook and MacBook Pro, which can't be said for most USB batteries.

A fast wall charger

If any of your devices support fast charging, you should pick up a wall charger that can keep up. 

Anker's supports Quick Charge 3.0, PowerIQ, and VoltageBoost, so you should be getting the fastest charging experience regardless of which devices you use.
