I was able to try the IonSlim 5K for USB-C ($54.95) from Moshi before it was released. Like other Moshi products, it's elegantly designed, with quality materials, including anodized aluminum. At 8.5 mm, it's also incredibly slim, almost as slim as an iPhone 7, yet it provides 5,150 mAh of power and Fast Charging at 15 Watts (5 volts at 3 amps), which is impressive given the thickness (or lack of thickness.)

With such an infinite array of wired and Bluetooth headphones for running and working out, how do we know our money will buy an investment and not another piece of temporary tech? Headphones are a very competitive electronics category with players ranging from obscure to household name. As a complete and total music nerd, I have owned many a headphone pair. Studio monitors, wired and wireless earbuds of every gimmick and design, Bluetooth on-ears, in-ears, and over-ears, and countless random sets from disposable to decadent. Headphones have been an emotional receptor for me throughout my life, and a mirror for my artistic expression as a musician. Just over three months ago, I began a rigorous workout schedule, and I knew I would need the best sport headphones I could find. I played with a few wired and Bluetooth headphones for working out before I had the opportunity to write this article, and saw it as the perfect way to test these workout headphones in the field. Well, actually I tested them in the gym, in the field, on the trail, on a bike, and on a skateboard, but I think I covered some solid ground during the tests.

Did you know that you can send and receive money from your friends via Facebook Messenger? I didn’t until I received a notification informing me that my sister had sent me $5. It seems there are a million apps for sending friends and family money these days, from Venmo to Snapchat. But if you already have a debit card connected to your Facebook account, then using Messenger to send or request money on iPhone is the quickest way to go. Here’s how to send and request money via Messages on iPhone.

There are various ways to share Kindle books. With friends, you can loan ebooks out for a couple weeks. But if you set up Family Sharing with Amazon, you can share Kindle books with family members easily and with fewer limitations. When you share Kindle books, the recipient can read the Kindle book you lend them via the Kindle app on iPhone or iPad, as well as Kindle devices, including Kindle Fire. Kindle family sharing allows two adults to create an Amazon Household with up to four children. The two adults in your Kindle family must have separate Amazon accounts. However, setting up family sharing and sharing Kindle books with your Amazon Household is actually quite straightforward. We’ll go over how to set up Family Sharing on Amazon, how to share Kindle books with that family, how to access content shared with you via Amazon Kindle family sharing, and how to leave an Amazon Household should you need to in the future. Here’s everything you need to know about how to share Kindle books with family members.

Since the release of iOS 8 a few years back, the Mail app on iPhone has swipe options. This means that when you’re viewing an inbox, you can swipe an email left or right to select options such as mark read/unread, delete, flag, or archive an email. Plus, tapping the More option gives you access to all the other email actions. However, you can choose to customize these gestures, though the options are somewhat limited. And you can even turn them off, if you so choose. Here’s how to change mail swipe options in Settings on iPhone.
